GSP Updates

Everything you need to know about Water Year 2020: Kings Subbasin Annual Report update

The North Fork Kings GSA (NFKGSA), together with the six other GSAs in the Kings Subbasin, submitted the second Annual Report to the CA Department of Water Resources (DWR) by the April 1, 2021 deadline.  Dryer conditions in water year 2020 (Sept 2019 – Oct 2020) strained groundwater supplies across the Kings Subbasin, evidence that cooperation among groundwater users and strategic surface supply management will be critical to achieving sustainability by 2040.

The Annual Report includes an overview of groundwater conditions in the region including groundwater extraction, surface water supply available for groundwater recharge, total water use, change in groundwater storage, and a description of progress made toward implementing the Groundwater Sustainability Plan (GSP) since the last Annual Report.

The Sustainable Groundwater Management Act (SGMA) requires Groundwater Sustainability Agencies (GSAs) to submit annual reports to the Department of Water Resources (DWR) on April 1 of every year.

Here are highlights from the Kings Subbasin’s 2020 Water Year:

  • Water years 2017-2019 were overall wetter than average but were preceded by an extremely dry period.  Overall, the last five years result in near average conditions, but they include an extreme dry and an extreme wet year.
  • Water use for Water Year 2020 consisted of 1,353,000 acre-feet of groundwater and 958,000 of surface water. Total water use for Water Year 2020 (WY 2020) equaled 2,311,000 acre-feet, with 2,011,000 acre-feet of the total used for agricultural purposes and 300,000 for urban use.

The Kings Subbasin saw improvements in groundwater storage in the 2019, but dryer conditions in 2020 led to the reduction observed in this year’s Annual Report. In light of the Annual Report, the North Fork Kings GSA is taking the opportunity to develop and execute the best strategy to achieve sustainability and secure water supply for its landowners and stakeholders. Projects efforts to date that will help provide a groundwater supply buffer for landowners to use during the dryer years include:

Development of a Groundwater Banking Policy that outlines parameters for landowner groundwater banking projects within the jurisdiction of the North Fork Kings GSA. The policy’s objectives include improving groundwater conditions, increasing water supplies, assisting in meeting Groundwater Sustainability Plan (GSP) objectives, providing flexibility to landowners, and ensuring no negative impacts to overlying owners.

Installation of a multi-completion monitor well through the Department of Water Resources Technical Support Services program. This well will increase data capacity and monitor sustainability progress to ensure NFKGSA is achieving its mitigation targets.

Completion of the Basin 11 Improvement and Expansion Project. The project consisted of the development of a groundwater recharge basin on a 52-acre site using Kings River floodwater as the primary water source. This basin improved conveyance capacity of the Liberty Canal by constructing a turnout and check structure, flow meters, a basin with exterior levees, a settling pond, an outlet to Murphy Slough, and monitoring wells.

Completion of the Terra Linda Recharge project. The project consists of a percolation basin located south of the Mendota Pool and adjacent to the Fresno Slough. This project decreased groundwater salinity levels to benefit domestic wells and the City of Mendota.

Progress on the Laton North Recharge Project. The purpose of this project is to utilize excess surface water for groundwater recharge by diverting water from Cole Slough, a distributary of the Kings River, into a groundwater recharge basin during wet years. The proposed project will involve the construction of a groundwater recharge basin and maintenance of an existing inlet structure to accommodate an additional 36″ mainline pipe. The project would utilize gravitational flows and would not require electricity or permanent on-site personnel to operate. All surface waters for the project will be supplied by Laguna Irrigation District in the form of its Pre-1914 water supply during flood events.

NFKGSA will continue to implement innovative projects that will lead to a sustainable, resilient, and steadfast supply of groundwater for the region.

North Fork Kings GSA joins regional agreement to monitor land subsidence

At the July 22nd Board Meeting, the North Fork Kings GSA approved a cost-sharing agreement between Groundwater Sustainability Agencies (GSAs) in both the Kings and Tulare Lake Subbasins for subsidence monitoring. The Kings River Conservation District (KRCD), a regional special district with diverse water resources management roles, proposed the agreement to support the Subbasins’ monitoring efforts under the Sustainable Groundwater Management Act (SGMA).

Because declining groundwater levels can cause surface elevations to lower, subsidence is an indicator of groundwater sustainability under SGMA. Over time subsidence may lead to what SGMA terms an “undesirable result”, for example damage to infrastructure like canals or roadways. Consistent monitoring across the region is key to preventing significant rates of subsidence from causing undesirable results.

The cooperative agreement approved by the North Fork Kings GSA provides funding to increase both the magnitude and frequency of KRCD’s subsidence monitoring program. Established in 2010 with surveys conducted every 2-5 years at 125 monuments, the current monitoring is too infrequent to meet SGMA’s needs for reporting on subsidence conditions and critical data gaps exist in the network. The agreement will allow KRCD to conduct surveys annually and establish an additional 71 network monuments that fill known data gaps.

Subsidence data collected by KRCD over the years was used in the development of the North Fork Kings GSA’s Groundwater Sustainability Plan (GSP) and has been referenced by GSAs as a source for mandatory SGMA reporting to the State. Cooperating with KRCD and the GSAs is a cost-effective solution to bring robust data to the table for successful groundwater management.

The agreement outlines cost-sharing of 8% between eleven GSAs in the two subbasins, while KRCD will contribute 12% to the overall cost. The cost for 2020 monitoring is estimated in the agreement not to exceed $30,000. The South Fork Kings GSA and Southwest Kings GSA, both located in the Tulare Lake Subbasin, have approved the agreement. The remaining GSAs are currently considering approval.

Annual Report Submitted to the State, First of Many on Kings Subbasin Groundwater Conditions

The North Fork Kings GSA together with the six other GSAs in the Kings Subbasin submitted the first Annual Report to the CA Department of Water Resources (DWR) on April 1, 2020. A requirement under the Sustainable Groundwater Management Act (SGMA), the Annual Report serves to inform and update both the State and stakeholders in the Kings Subbasin on groundwater conditions and sustainability progress. Thanks to favorable hydrology for the reporting period, Kings Subbasin groundwater conditions improved overall with storage increasing by 210,000 acre-feet Subbasin wide.

The report indicates groundwater extractions in the North Fork Kings GSA represent an estimated 17% of total 1.06 million acre-feet extractions in the Subbasin. Irrigation Districts and landowners alike in the North Fork Kings GSA took every opportunity to capitalize on available surplus surface water supplies, capturing Kings River water during flood releases to recharge in basins or use on farms, offsetting groundwater use. The Annual Report focuses on water year 2019 (Sept 2018 – Oct 2019), a hydrologic “wet year” seeing 134% of average diversions on the Kings River, the majority of surface water supply to the region.

The North Fork Kings GSA plans to expand its groundwater recharge capacity at both the landowner and agency level to take advantage of similar wet hydrology in future years. Partnering with landowners to implement on-farm recharge practices, constructing recharge basins, and expanding existing recharge facilities are all strategies outlined to achieve a sustainable groundwater supply. The combined efforts of the North Fork Kings GSA and six other cooperating Kings Subbasin GSAs will ultimately lead the region to long-term sustainability.

The data for the report was collected from the seven GSAs’ monitoring networks, groundwater extractions, surface water supply, total water use, and changes in groundwater storage. Combined surface and groundwater use in the Kings Subbasin across sectors including agriculture, urban, and managed recharge totaled 2.7 million are-feet for the period.

Considering this first report was prepared just months after the submission of the Groundwater Sustainability Plans (GSPs), the data does not stray from data already included in the seven Kings Subbasin GSAs’ GSPs. Although the Subbasin used the opportunity to include any additional data collected through the reporting period and established a template for future reports.

The North Fork Kings GSA adopted its GSP on December 18, 2019, marking the transition from the planning to implementation phase. Following the adoption of a Groundwater Sustainability Plan (GSP) SGMA requires GSAs to submit annual reports to DWR on April 1 every year as a tool to track and communicate GSP implementation progress.

There is no grading or scoring criteria on the Annual Report, and DWR expects this first report to be missing some information considering the short timeframe between GSP adoption and the report due date.

After Two Years, Groundwater Plan Adopted, Implementation Begins 2020

Riverdale, CA – The North Fork Kings Groundwater Sustainability Agency (NFKGSA) Board unanimously adopted their Groundwater Sustainability Plan at the December 18 meeting. NFKGSA’s Board is proposing a phased approach over 20 years to mitigate the target overdraft of 59,000 acre feet per year, NFKGSA’s allocation of the Kings Subbasin total annual overdraft of 122,000 acre feet. Board Chair Mark McKean thanked the plan developer Provost & Pritchard, staff and the Board for all of their work over the last two years. “This Plan is a living document,” stated McKean. “We realize it isn’t a perfect document but a building block and in five years we will have a better Plan than we have today by working together.”

The NFKGSA will use the Groundwater Sustainability Plan (GSP) as a roadmap to balance its groundwater.  The GSP includes potential policies and projects that will impact groundwater management in the region for years to come as the North Fork Kings GSA works to achieve sustainable groundwater supply. Technical consultant Provost & Pritchard worked over the last two years collecting data that documents historic and current groundwater conditions; the GSP uses this information as the foundation to define a path forward for how groundwater will be managed. The overdraft can be balanced using both supply-side and demand-side solutions. The toolkit of projects and management actions will include both, but the NFKGSA Board plans to prioritize supply-side solutions including floodwater capture for groundwater recharge.

NFKGSA is the one of seven groundwater sustainability agencies that will coordinate to achieve sustainability in the King Subbasin, a critically overdrafted groundwater basin that lies within Fresno County. Once all seven groundwater sustainability agencies adopt their plans, they will be submitted together with a coordination agreement to the State prior to the deadline of January 31, 2020. 

Stakeholders can review a full draft Groundwater Sustainability Plan, now available for download

At the July 17th Board Meeting, the North Fork Kings GSA Board approved opening the draft Groundwater Sustainability Plan (GSP) 90-day public review and comment period. Members of the public are encouraged to download the GSP on the website at northforkkings.org/gspcomment and provide comment for the agency’s consideration.

The GSP includes potential policies and projects that will impact groundwater management in the region for years to come as the North Fork Kings GSA works to achieve sustainable groundwater supply. Technical consultants worked over the last two years collecting data that documents historic and current groundwater conditions; the GSP uses this information as the foundation to define a path forward for how groundwater will be managed.

The North Fork Kings GSA will use the GSP as a roadmap to balance its estimated 59,000 acre-feet of annual groundwater overdraft by 2040. The overdraft can be balanced using both supply-side and demand-side solutions. The toolkit of projects and management actions will include both, but the North Fork Kings GSA Board plans to prioritize supply-side solutions including floodwater capture for groundwater recharge.

Members of the public are encouraged to take part in the important process of defining the path forward toward groundwater sustainability. The public comment period will conclude at the end of the day on October 21st.

The North Fork Kings GSA is hosting workshops in August to review what is in the GSP and how it impacts those with a stake in groundwater management. View the GSP calendar for workshop details: GSP Calendar.

Our water needs a budget

Water is scarce. Sustainability of the resource we all depend on requires balanced inputs and outputs. Whether SGMA is the compulsion or not, responsibly managing water demands a budget.

In the Kings Subbasin we’re working to balance an overdrafted water “account”. The North Fork Kings GSA, along with the six other GSAs in the Kings Subbasin, is required by SGMA to bring its account into balance by 2040.

A water budget, required in the Groundwater Sustainability Plan (GSP),  provides valuable insight for those managing our water. It informs current conditions and will measure impact of the North Fork Kings GSA’s upcoming sustainability efforts.

The budget tracks water inputs and outputs to calculate the change in groundwater storage in the service area. A negative groundwater storage indicates overdraft.

Groundwater Storage = Inputs – Outputs

Sustainability can be achieved by increasing water supply (inputs) and/or decreasing water demand (outputs). The GSP will define how the North Fork Kings GSA plans to balance its estimated 50,300 AF of annual overdraft. The GSA can increase its inputs, decrease its outputs, or a combination of both through projects and management actions. For example increasing inputs through flood water capture off the Kings River in wet years can offset irrigation outputs, bringing the budget closer to balance.

Inputs are water sources, and can include additional surface water, precipitation, estimated groundwater pumping, and groundwater inflow. Outputs are water uses, and can include irrigation, municipal, residential, and industrial uses, as well as groundwater outflow. The North Fork Kings GSA is committed to prioritizing supply side solutions for sustainability.

A water budget is a key component of the Groundwater Sustainability Plan (GSP), and will be included in the draft document scheduled for public review beginning in July.

When Water Supply is Scarce, Management Actions can Mitigate Overdraft

There are only two ways to achieve sustainability and eliminate groundwater overdraft for the North Fork Kings service area: increase water supply, primarily through project development and reduce water demand, primarily through management actions. The NFKGSA Board is emphasizing increasing water supply with the understanding there are hurdles to overcome.

The preliminary project list continues to be updated and contains recharge projects that would yield an estimated annual average of approximately 50,000 acre feet per year based on historic floodwater availability. The seven Kings Subbasin GSAs have reached agreement on an initial overdraft amount for the entire Kings Subbasin of 122,000 acre feet. The North Fork Kings GSA estimated amount of the 122,000 acre feet is 50,300 acre feet. 

The amount of overdraft that cannot be overcome with increasing the water supply will need to be overcome with management actions that reduce water demand.  Demand reduction through management actions will likely need to be initiated within 5 – 10 years if project development isn’t progressing as needed.

Management Actions are programs and policies that will aid the GSA in achieving sustainability primarily through water demand reduction measures and improving data monitoring.  A suite of potential management actions will be presented in the GSP that could be implemented at the GSA level or landowner level. The GSA may not want to dictate management actions at the landowner level, what works for one landowner may not work for another and economic impacts must be considered.

Below are potential management actions that will be considered in the GSP and the estimated time for implementing those actions.

Proposed project would recharge an estimated 15,000 AF annually in the North Fork Kings GSA

A portfolio of solutions will be considered to achieve sustainable groundwater under SGMA. Projects and management actions can work in tandem to augment water supply and reduce water demand, stabilizing groundwater levels. The North Fork Kings GSA Board’s first priority is implementing projects to increase water supply in the service area. The North Fork Regional Recharge Project introduced by Kevin Johansen, Provost & Pritchard, aligns with that priority. The project is in early conceptual stages.

Three groundwater recharge basins with estimated annual recharge capacity of 15,000 AF (acre-feet) are included in the project scope, leveraging suitable recharge conditions in the GSA’s northeast region. The average annual cost per AF of recharge is $160 according to preliminary project cost estimates. The project includes two new basins and expansion of an existing Laguna Irrigation District basin. An additional component needed is improvement and expansion of Liberty Canal to increase current carrying capacity and secure water delivery.

Surface soil type, absence of clay layers, and groundwater flows at project sites are highly conducive to recharge that benefits the entire GSA’s service area. The bulk of surface soils at proposed sites are coarse sands and sandy loam, ideal for percolation into the groundwater aquifer below. And although much of the GSA is underlain with clay layers, the northeast region is absent of these layers. Because groundwater generally flows east to west in the GSA, the groundwater recharged by the project would flow into the rest of the service area. This includes to disadvantaged communities of Lanare and Riverdale where soil type and clay layers are unsuitable for recharge projects.

To help cover project cost, the North Fork Kings GSA is pursuing grant funding through Integrated Regional Water Management (IRWM) Prop 1 Implementation funds. A pre-application was sent to the Kings Basin Water Authority for review and if selected, will compete for funding from a pool of $12.7 million for the Tulare Kern Funding Area.
