Hello all. For some of you this will be your first information email as I am entering off the signup list from last night and they have also been coming in all day from the website. It will be a little repetitive for a few days as I will be sending some of the same information over the next few days as I enter names in batches of about 50 as we have around 200 requesting to be part of IPPA information and or as volunteers. I need to do them in batches as I add the names and email addresses because I must test the emails for deliver because sometime its shard to read the writing from signup and or I might enter it wrong, but in either case I will fix those as they are rejected if incorrect for whatever reason. I am receiving information from several of you and from Dave Merritt at KRCD. At the same time requests for assistance have also been coming in today. I am logging all the requests in and answering each with an approximate day we will address the request issue. I will share those as we will need to work together to accomplish all requests as timely as possible. I will always answer them personally every day or have someone on the standby team do that. We will talk about the standby team in a day or two as we get more signed up. Meanwhile we have some extra filled sandbags coming in tomorrow from Visalia and a place for them to go as a request for help came in from someone that needed assistance with that. We have several elevations help requests and other concern requests on the levee conditions in their areas. For the new people on this list tonight I am attaching an email I sent out this morning on a message from Dave Merritt from KRCD answering the concerns from last night about debris build up on the railroad trestle on the South Fork. It includes pictures of the action they took today. Stand by for lots of information over the days coming in real time. I have also added the two videos from last night to the website under the Public Notice tab. Be well friends.
Hello all. We are sending this out as Notification # 002. We now have a little over 200 members and we have had over 4,000 visits to the website which means we have many more friends out there praying and willing to help us if needed. Because of the size of the membership and the time to make the entries we are sending this notification out in groups. We are still working on the “text notifications only” list as some do not have emails and or want only texts messages. We continue to update the website with ideas from you and things we think of as time passes and requests come in. We have had 13 requests for direct information, and or assistance, and 11 of those have been completed. If you remember, at the meeting we made two main promises; “We will always answer the call for help and all the people, have the right to know all the information, all the time". The only exception to that is if people ask for help, we handle that on an individual basis with them and the volunteers as we do not openly share personal information, for example where someone might live alone or be a single parent with children. We also do not share when people need help with technology or computer work as we want people to feel comfortable requesting that information.
Given all that, we have a need for a couple of volunteers with a pickup truck to deliver sandbags to a person who cannot not do that on their own. The bags are already filled with sand and staged a mile from the residence where they need to go. Please contact me, or one of the other contact team members, Jim Verboon or Marilyn Vieira. My number is below and all three of our numbers are in the contact section of the website. If you reply to requests and or to notification emails, please consider if the reply should go to the entire group or to just the sender as that will keep people from getting repetitive emails. You are of course always welcome to reply to everyone as needed.
These resources were added to the website today as recommended by KRCD. The flow has increased some today. Be well, be safe.
Release changes at Pine Flat Dam - https://www.spk-wc.usace.army.mil/fcgi-bin/release.py?project=pnf
Hello all. KRCD has set up the email below to assist those that find areas of concern on the river that they think should be looked at and watched. We realize that not everyone uses email, but if you know of someone that has a concern to report you can email for them or anyone can call one of us contact team members and we will report it on their behalf. We are also adding it to the website. This does not replace the need to call in case of an emergency, but it does give an additional way of reporting concerns. I would advise if you did report something please consider copying one of us on the email to keep a recorded log. You can also cc. info@ippa.life. Be well neighbors.
KRCD email to report information and or concerns about the rivers. flood@krcd.org
We hope you will get used to reading this information regardless of the source so you can feel good about knowing where we currently are. If you have any questions about his report, please reach out to us. Be well, be safe.

Notification # 6
All notifications that have gone out are now archived on the website, and all new notifications will be archived as they are sent. Anyone that joined after the notifications began or did not see the earlier ones may do so on the website. A photo and video page has also been added and will be populated as we go along to provide photos and video for areas that all may not have access to but are furnished to the organization. Be well, Be safe.
Notification # 7
We are now at the stage where more and more things have been addressed just in case the worst of scenarios happens, but many questions remain unasked and or unanswered. As the temperatures are now rising and water flows will certainly increase, more and more questions will arise, and we would like to put those in the Q&A area to help others. In the Q&A area of our website we have addressed just a few of the questions that neighbors have sought answers to. We would like you to please send us any questions that you may have to share and or are seeking answers to. We will look for answers to all questions from sources that are nonpolitical and unbiased and post them in the Q&A section of the website. All questions will be posted and answered anonymously of course. Please help us by sending any questions via email or text directly to me to protect privacy and to minimize the number of emails that people receive through our system. A few examples of new questions that have come in are below. Please check out the IPPA website as the new Photo and Video section has a very amazing video of the Crescent Weir. Be well.
Q. Will the high river flow cause more mosquito problems?
A. Yes, not from the flows but from the seepage that is occurring and will cause stagnant water.
Q. Should we be concerned that there could be rattlesnakes washed downstream into our area as the snow melts and runs off?
A. Pending from Fish and Game
Q. If there is a breach in one part of the Island area will PG&E disconnect power from that area and if so, would that affect other areas surrounding the breach?
A. Pending PG&E
Notification # 8 (Priority Message) 04/24/23 6:05 PM
We are sending this email out with a priority designation rather than our previous messages which were keyed as informational. Going forward notifications will have one of the following designations 1. General Information 2. Priority 3. Urgent 4. Alert. The temperatures are going to rise significantly over the next several days (high 90’s) before they simmer back down a bit. The agencies have done very well on their releases and space has been created at Pine Flat. At some point the inflows will begin to rise more dramatically and we need all to work together to manage the outflows. There is no doubt the agencies have planned for this, but mother nature has much to do with the next steps. We are asking all farmers, either hobby or full production types, to take and use as much water as you can during this period to help reduce the flow from the rivers. The canal districts are asking that users commit to running consistently seven days a week and do not cut back on the weekends. Some farmers where they can, will be using flood irrigation instead of their drip. Farmers manage best at that and only they know if that works for them depending on their situation and proximity to the rivers.
Recently there was what was thought to be a mysterious airplane flying a grid over the Island District. It in fact was an agency establishing current elevations in our area within a foot of accuracy. The link below will take you to the site. If you have not done so go to our website and view the newest pictures and videos to help you understand what is happening out there. There is one video of the Crescent Weir and the other is the way to transfer water from the North Fork to the Crescent Bypass by huge siphon pipes. Six of the eleven siphons are currently running. If you watch these videos on a desktop or laptop turn up the volume and you can hear all the sounds of the force of water and nature.
Notification # 9 (Priority Message) 04/26/23 11:15AM
We are sending this email out with a priority designation as all from now on until this challenge passes will carry this designation or higher if necessary. Going forward notifications will have one of the following designations 1. Priority 2. Urgent 3. Alert.
The temperatures are rising significantly over the next several days (high 90’s) before they simmer back down a bit. The agencies have done very well on their releases and space has been created at Pine Flat. The inflows and outflows are rising given the temperatures and the calendar. As mentioned before there is no doubt the agencies have planned for this, but mother nature has much to do with the next steps.
Given the more accelerated stage we are in now we ask that you review your evacuation plans just in case. This should by no means indicate that we expect a breach or flooding soon, but just want you to focus on what you would do if you had not already planned for that. The two links below are excellent sources for flood evacuation plans provided by FEMA.
We are now asking any volunteers that wish to provide their capabilities to move animals with stock trailers of any size to contact me by email. I will set up a special alert schedule for that and all that are on the list, your information is kept confidential, and you are only called upon if needed.
The other side of this stage is for us to now know if anyone out there has animals that might need to be moved and has not planned to do so already. If you contact me by email and provide your contact information with the type and number of animals, we will also set up that schedule for possible alert action. Your personal information will also be kept confidential.
Thanks to all that have provided important questions and possible scenarios to us. We have posted those with answers in the Q&A part of the website. Be well, be safe
Notification # 10 (High Priority Message) 04/28/23 07:52AM
We are sending this email out with a priority designation as all from now on until this challenge passes will carry this designation or higher if necessary. Going forward notifications will have one of the following designations 1. Priority 2. Urgent 3. Alert.
Jim Verboon attended the old Kings River area meeting representing the area above the north-south split at the Kings River Hardwick School last night. Below is his report.
The meeting at Kings River Hardwick School last evening went well. Steve Haugen and David Merritt with Buddy Mendes giving reports. David complimented Stone Land Company and Tony for the help and involvement. They are actively pursuing pre- staging flood defense materials to repair potential breeches.
They were happy to report PFD storage to be below 440,000 aft at that time and still going down despite the 10,000 cfs inflow and Steve stated they would be continuing holding the river stable to continue the same splits at the Corps and Island Weirs.
We complimented the great cooperation between the Counties, KRCD and KRWA for maintaining a STABLE river during challenging times. We expect to have a high flow situation for a couple more months. They are expecting the peak inflows to be 26 to 28,000 cfs barring unforeseen events. Mother Nature is helping now and hopefully into the future. Mill and Hughes Creeks are not big factors with snowmelt.
Note: One of our members did report that it appears we had a ~1 ft surge last night on Clark’s Fork at Grangeville and 22nd? The member was kind enough to provide photos to demonstrate the change. Big thank you for that!
Notification # 11 (Informational Message) 04/29/23 09:41 PM
We are sending this email out with an informational designation as we thought it would be nice to share with all of you an example of one of the many requests your system has accomplished. The pictures attached are a before and after spot in the river that one of your neighbors had real concern with. The admin team reviewed the situation with the neighbor and KRCD and we are pleased to say the agency stepped in and strengthened the area. We continue to take photos and information in areas of concern that we observe or are brought to us by request from you. Please be proud of the efforts of all your neighbors and how we as a community have come together. Below are the stats to date of your organization. Be well, be safe.

We are sending this email out with a priority designation as all from now on until this challenge passes will carry this designation or higher if necessary. Going forward notifications will have one of the following designations 1. Priority 2. Urgent 3. Alert.
We are delivering this message this morning not as an alarm by any means, but rather recognizing a day of historical inevitability. Due to the calendar and recent high temperatures the inflow as indicated below is greater than the outflow at Pine Flat Dam. This had to happen of course and the cooler temperatures this coming week might slow down that process. The agencies have done well to prepare for this event and going forward will manage by discharge and use of water flow through the main channel and the forks of the North and South while using the space created at the dam as their buffer. I believe Jim Verboon summed it up best this morning when he sent Marilyn and me this message.
“The DAM is officially earning it's keep as it is retaining more water than releasing, while keeping stable, manageable flows downstream. Still the same height at Hardwick Bridge this AM.

Notification # 13 (High Priority Message) 04/30/23 02:34 PM
This notification has been raised to a “High Priority” given we are entering the next phase of surveillance and prevention strategies given the calendar and higher temperatures and to resolve an issue that has concerned us some since the activation of IPPA. Things have been going well in our organizational work, working with agencies, and completing requests for assistance (47 to date). Now with more than 240 members, and 6,300 views on the website, we know that our community is active and obviously many from the outside of the area are watching what is happening in the Island District. What is missing is an early and timely alert system where all in the community can be contacted in case of a breach or other emergency during this period and done as quickly and safely as possible.
The IPPA early alert system (EAS), strictly voluntary, is now being organized where all neighbors in the community that want to be notified in case of a breach or emergency, and have provided a cell phone contact, can be notified in a timely manner (the whole community). This will not replace the email notification system but will only supplement it. What we are looking for are volunteers that will be Alert Leaders (AL’s). The volunteers will be given no more than 10 phone numbers to put in a group text by them to those citizens if they receive an alert from one of the emergency agencies, an administrator or a neighbor that has observed an alert emergency. The Alert Leaders will be given numbers without names and are to text the group once an emergency alert has happened. Anyone that does not take text will be called in lieu of a text once we know their preference. Jim, Marilyn, and I will have all the Alert leaders’ numbers split up and, on our phones, to notify them and then they will alert their groups. What I did on my own phone was I listed those that I have to notify that want text only not emails, I added them in my contacts as IP-1, IP-2, etc.
We are looking for about a dozen or so volunteers that are willing to do this and are comfortable with texting. Our goal is that all persons living in the impending threat area are notified as quickly as possible. If you are willing to volunteer to join this alert group, please email me.
Special Note: This plan does not replace first calling 911 or the responsible agency for assistance. This is a neighborhood watch and alert system for our community to make sure all are notified if there is an emergency observed during this potential flood period.

Notification # 15 A Moment of Reflection and Calm (05/04/23) 10:20 AM)
With 7,000 views of our website and numerous emails from people across the nation we know that individuals are watching our situation and hoping for the best. This week I was asked if we have been lucky with the weather and general conditions. I answered this way and then went on to explain generally where we are today. Given the adage that “Luck is defined as when opportunity and being prepared meet”. Our opportunity was when we met and the neighbors decided to work together in a common cause both as a group and as individuals cooperating in IPPA, the organized Facebook platform, and in every home and coffee shop in the area. Opportunity was also those neighbors banning together to work with and support the local agencies that are 24/7 protecting our community. Preparation speaks for itself by the actions of every member of this community with boots on the ground watching and doing what is necessary to fix things and being prepared to act for each neighbor if needed. Preparation is at the forefront of local agencies’ daily duties as they continue to manage the water flow and with 24/7 surveillance along the rivers. Given all that, yes, I guess “we are lucky”.
Mother Nature has bought us a little time, and time and flow days are what we need to move past the apex point of melting snow versus safe release. As you know we in the Island District live surrounded by a triangle of three rivers, the North Fork, South Fork, and the Crescent Bypass. At some point down the road three-million-acre ft. of water will have passed this area to be used in farming, take the North Fork to users or on to the ocean, and the South Fork for farmer usage and that continues to flow to the Tulare Lake basin. Pine Flat being the main storage area above us we watch the inflow versus the outflow. When the inflow exceeds the outflow, that could fill and if that point comes and they cannot safely continue to release at a manageable rate, that is when things could become dangerous. The agencies have done an outstanding job of managing the flow and reducing the water behind the dam therefore increasing buffer storage space behind the dam. Right now, we are in much better shape than we were just a few weeks ago but the snow pillows just taken show we do have some record snow fall and water content in areas feeding the Pine Flat Lake. I am placing two links here. One shows the Army Corp's hour to hour report of outflow versus inflow, and storge behind the dam, and the other is the NOAA inflow predictability chart based on weather conditions. You will notice that just a few days ago the inflow was greater than the outflow, but cold weather has now slowed that down. With these high rates of daily flow through the district it is about holding on long enough to get through the critical point that will come in the next several weeks. This will be the inflow versus out flow, capacity in the lake, usage, and the flow rate in the channels. Meanwhile everyday agencies and citizens watch, pump seepage, trim dangerous tree situations along the river and repair areas of concern. We do think that things are getting better but the continued saturation from the high flows and the probability of warming temperatures that ultimately will come, means we stay ready and prepared to act.

Notification # 16 Water Flow Reduction
We were just notified that the flow in the South Fork is being reduced by 200 cfs. You should see a difference by late Sunday or early Monday. Good management has allowed this easing which in turn will help reduce the seepage and levee issues along the South Fork.
Notification # 17 Looking Forward 05/09/23.
The reduction in the flow of the South Fork did take place at around 200 cfs and yes, it was slow to see a change in the level as it takes time to mitigate through the system. We thought it might be time to look at where we are and where we are headed. The high flow over a period keeps us vigilant because of seepage, possible tree degradation inside the river which could cause one to uproot, and always the threat of a possible breach. The other side of high flows over a longer period is that for every day that goes by that much water has been released and, in our case, additional buffer space has been created behind the dam. PFD storage is at 364,000 (10:15 am) this morning giving us 700,000 or so buffer space in storage. The outflows continue to be larger than the inflows which at some point will most likely change as the weather heats up and the snow continues to melt at a higher daily rate. A little math might give some comfort here. If the average of out flow has been 13,000 cfs (26,000-acre Ft.) since April 1stand continues to May 15th that is equivalent of 26,000 x 45 = 1,170,000 that has been used or passed us by and 700,00 of buffer storage has been created. Below I am placing a direct report from Jim Verboon as he is kind of our Daniel Boone type of guy who tells it the way he sees it and, in his case, a genuine way of what his brain and heart tell him.
“We are better off than I would have forecast six weeks or more ago, PFD at 388 thousand aft with 12894 cfs outflow and 8284 cfs inflow at 4AM. However, the COOL weather has been a blessing at gaining flood control, the corresponding result is it did NOT melt a lot of snow, meaning when the heat comes, we potentially can see some very high flows that if short in duration can be handled. KRCD and KRWA members have done a great job of keeping a stable river while adding (continuing) control space behind the Dam. The next MOVE is MOTHER NATURES'. Thanks to all involved and we need to stay vigilant for seepage control and weak spots, falling trees, etc. NOT out of the woods yet”. Jim Verboon
Notification # 18 Looking Forward 05/10/23.
The following disaster relief meetings have been set up by the KCFB for public information and assistance. Please open the file for times and locations. One is tonight at West Hills College Lemoore.
Notification # 19 Alert System Announcement 05/12/23.
With this notice we are announcing that the text and phone call alert system has been put in place at IPPA. This system is to notify the neighbors by text and or phone if an actual breach has occurred. We are as a community working hard to prevent such an event and the agencies have done an exceptional job of managing the water and levee system. We are entering the next phase of the water year where temperatures are increasing, snow will melt at an accelerated pace, and higher flows continue and may increase. As the previous notifications have pointed out planning and management have helped as we have safely used or passed a great deal of water through our area and significant space has been created behind Pine Flat Dam. This alert system is just in case a breach does happen and we will use every possible mode to notify those living in the area by text, phone, email, and word of mouth and in a the most expedient time frame. There have been team leaders set up and we have assigned a certain number of phone numbers to each of those teams who will text and or call everyone on their list if an emergency happens.
Notice: This does not replace calling 911 immediately if an emergency happens.
“The rivers are raging, but be not afraid, the neighbors are watching a plan has been laid, from sunrise to sunset, by star’s pure light, the neighbors are watching, sleep restful tonight.”
Notification # 20 Snow Measurement and Warming Temperatures 05/13/23
As we send out this notification it is apparent to all that a warming period is upon us for a while. We knew this would come as it is that time of year. Now is when all the management work will pay off even though it will test our endurance and patience. Some of you have received from other sources the latest snow survey taken on May 12th. We realize at some point one might get information overload but during these times more is much better than less in knowing what we are facing. I am placing the snow survey link below and when you open it, please note that we are in the southern region which means all the Corcoran area is also. It will continue to be a very challenging time for the people in the Corcoran area as they have several rivers and streams flowing their way, not just the South Fork of the Kings. You will notice in the survey that some areas are 400% of normal. There were 20 locations tested for the southern region and if you click on the initials of each down at the bottom of the page it will show the snow and water content from April 13th to May 13th. What one might focus on is what is left in each of those areas tested. Some lower elevations are nearly depleted while others show an abundant still to melt.
The inflow will now be greater than the outflow and will be countered by the storage buffer accumulated behind the dam, increased usage by agriculture due to the warmer temperatures, and possibly the necessity to increase outflows through our region. We await comments from the agencies about what the plan will be given the new snow updates, increased inflows, and rising temperatures. We will pass that on as received.
I want to personally thank Ron Alvin for his continued linking the various groups of IPPA, Clarks Fork, etc. by sharing information with all.
Jim Verboon sent this message this morning.
“It looks like we start the "snow melt season" with the DAM 1/3rd full as the inflow will match or be greater than the outflow starting today. Our Agencies have done a good job of keeping the river at bay while gaining control space behind the DAM. The next 30 days are crucial for flood protection as we need to hold enough water behind the DAM to move the water both NORTH and SOUTH without breeches and without allowing it to completely fill up. We are NOW in the official REACTIONARY phase of our flood year. MOTHER NATURE moves and we must REACT to the best of our ability and PRAY we do good enough and MOTHER NATURE GIVES us a WIN!”
Snowpack Measurements
Notification # 21 Current Data and Modeling 05/16/23
As we send out this notification it is apparent to all that the warming period has continued which in turn has accelerated the snow melting in the water shed for Pine Flat Dam Reservoir. Since the last notification some notable things have taken place. The cuts to the South Fork have been apparent and given some relief to those along the river, especially in the Clarks Fork region. This period has given much thought to the latest B-120 WATER SUPPLY FORECAST SUMMARY (attached) and the appropriate adjustments to modeling, if necessary, given the estimated remaining snowpack, daily inflows, increased water usage demands and the necessary outflow to keep it all in balance. Given all that, and the requests by several of the members to seek what modeling the agencies are currently using to determine outflows from PDF, we made the following request by email to KRCD and KRWA.
The email we sent: Monday 05/2023 10:37 AM
Gentlemen. Given the current situation of sustained warming conditions, the newest snow measurements, and the possibility of required higher flows; we are requesting on behalf of our members, either in writing or in a personal presentation, the models that you are currently using to plan for the next 30 days of increasing inflows to Pine Flat Reservoir. Especially considering the recent decrease in flows through the South Fork. We truly appreciate the management actions by your agencies that have taken place thus far in preparing for the inevitable temperature increases and inflows both for water releases and levee security. It is a nervous time for property owners in our area and the sharing of your models would help calm the anxiety of the unknown factors that face us all.
We received an email message back this morning from David Merritt KRCD with his modeling and an explanation of how it works. I have attached the information and modeling on a word document. The below link is included in his model, and it shows the forecasted water to be created in the Pine Flat area from October 2022 through Sept 2023. Please review the modeling and if you have questions, please feel to reach out to me, Jim Verboon, or other members you feel comfortable with to ask for clarifications. It is important to note that local agencies are put in tough spots during these times when considering public safety and possible property losses. If they are too aggressive it can make some fear the situation at hand and if they are not aggressive enough, they risk being blamed for not being responsible. We have great respect for the work that has been done over the last several months by our agencies and we give special thanks to David for being timely and transparent with his reply.
Note: David’s Model has this disclosure which is important to acknowledge: “Disclosure – the following is not guaranteed and is an assumption based on publicly available data, the USACE makes all final decisions on actual flood release requirements”.

Notification # 23 Where are We? 05/25/23.
Hello all. As you know we stay in constant contact with the local agencies and the boots on the ground so that we can report to you the information as it happens in real time. We asked David Merritt of KRCD to give his opinion of where we are and where we are headed given all the current data points of snow left, melt rate, inflows to PFD, dam storage, outflows PFD, current and projected irrigation usage, recharge, and mother nature of course. Below is his response and it speaks for itself but if anyone would like to talk about this feel free to contact one of us. As always it is our honor to help keep you informed.
From David Merritt KRCD
A couple items –
· DWR updated the B-120 forecast today – they increased the runoff in May by 65,000 AF and decreased June by 57,000 AF
· To meet their forecast for May, the inflow to Pine Flat would need to average 25,235 CFS (50,469 ac-ft) daily for the remainder of the month – based on forecasted temperatures, I do not see this happening. Even the long-range forecast looks very mild.
· The forecast for Upper Basin continues to cool and shows it potentially below average on the high side out to June 3 – this is helping to keep the melt more consistent over a longer duration, a potential good thing. https://www.cnrfc.noaa.gov/temperaturePlots_hc.php?id=PFTC1
· Snow surveys are occurring this week and will have more information next week.
· We continue to discuss on a routine basis with the USACE concerning future release needs.
Disclaimer – all data is subject to verification.
Notification # 24 We Approach Two Apex Points 06/01/23.
Hello all. We will use apex in this context as the peak of a curve before it drops off on the other side. The top of any curve graph typically will have an apex where it no longer climbs but reaches the point where it turns downward. In this case the apex will be the point where the runoff from the watershed behind Pine Flat will reach its maximum run off for the month, which at this point is the month of June. The number as you will see below has again been estimated at 1,090,000-acre ft. for the month of June and then dropping off to 745,000 in July. The other apex, which in this case will have a flatter peak, is the usage for irrigation and recharge. It is difficult to put an exact number on it, but the apex period starts somewhere around May 15th and goes on until August 30thth. This is the reason you see the outflow of PFD staying about the same the last couple of weeks but the South Fork levels dropping.
Below is the update received this afternoon from David Merritt. It is self-explanatory but we remain ready to answer any questions you might have. Be well.
From David Merritt KRCD
CDWR B120 was updated today –
· No change in June forecasted runoff – remains at 1,090,000 ac-ft
· A 43,000 ac-ft increase was made to July – 745,000 ac-ft
· We continue to meet with the USACE routinely each week and coordinate on flood release requirement from Pine Flat
· The forecast at 8,000 feet + continues to look very mild – a very slight increase with a rapid drop below average for the daily high https://www.cnrfc.noaa.gov/temperaturePlots_hc.php?id=PFTC1
· My updated routing is below –
We are still waiting on some additional data from the ASO flights that occurred last weekend and hope to have in the next couple days – I will share updates as I get more information.
Notification # 25 Where we are Now 06/08/23.
River Flows
As of today, the following are where agencies have adjusted flows going forward at least for the immediate future, and it is subject to verification and change of course.
Based on the current models of both hydrologic and climate the Crescent Bypass is now off and will not be used for flows. The South Fork flood release will go close to near zero with the flow fulfilling the irrigation and recharge usage. The North Fork will remain at 4,750 csf.
Sandbag recommendation by one of the members:
A lot of people have placed sandbags around their homes for possible flood protection and piled some up in case of last-minute emergency. All the bags that I have used have started to break down from UV light. If you try to pick them up, they shred like crazy. The bags were probably for immediate use to throw in a doorway or levee breach and not sit around waiting as we have. Everyone that has them needs to be made aware of this potential failure. I will be replacing several of mine and putting them under a tarp until needed.
Hello everyone. Attached is IPPA Notification # 26. This is not the final one for the year but close to it, as science, human courage, and prayer has paid off to mitigate what could have been potentially disastrous to the community of the Island District. This does not take from the damage that many of our fellow neighbors, farmers and businesspeople have faced in the Lake Bottom, Corcoran area, and several communities, and they remain in our thoughts and prayers. As you have watched the high flows for months flow past you on all sides, they now have been reduced significantly with no flood releases in the South Fork and the North Fork to be reduced meaningfully. The water management decisions that were made early, the maximum water use by those for irrigation and recharge worked, and mother nature was kind. As you review the attached notification with the current models provided by David Merritt you can tell the hard work has paid off. Please keep in mind the goal was to control flood flows for the preservation of life and to mitigate damage to property as much as possible. You will see by these models that at the end of July the PFD will be near full and the flood releases will be finished or near to it. Be well, be safe
As Provided by David Merritt General Manager KRCD
Attached are from the California Nevada River Forecast Center:
1. Chance of Inflow Exceedance to Pine Flat Reservoir – I set this to go through August 2023
2. Pine Flat inflow forecast through June 24th – a significant decline due to the Kings Rive Upper Basin significant drop in temperatures.
3. Kings River Upper Basin (8,000 feet and above) forecasted temperatures. We will potentially beat the record low temperatures at night.
The CDWR B 120 update for the April – July runoff volumes versus actual into Pine Flat Reservoir (all values are in acre-feet).
The June and July reservoir projections – these are my routings and subject to change. CFS outflow @ PF Dam
As of Sunday (6/18/23) the minimum at Pine Flat was 10,600 CFS – this will be reduced by 400 CFS today (6/19/23) and 400 CFS tomorrow (6/20/23) – the new target will be 9,800 CFS after these changes. We continue to work closely with the USACE and KRWA on further changes to the release rate at Pine Flat.
