Innovative project in MAGSA sparks interest from California water leaders

Don Cameron, MAGSA Board Chair, hosted a public tour of the McMullin On-Farm Flood Capture and Recharge Project at Terranova Ranch following the meeting of the California Water Commission in Kerman. California Water Commissioners Armando Quintero, Carol Baker, and Maria Herrera joined the tour.

The tour group visited several sites along the project, still under construction. Once completed the project will provide an opportunity to capture available flood flows onto farm land to mitigate downstream flood risks and provide for groundwater recharge.

An important tool in the SGMA toolbox, groundwater recharge projects have the potential in years of excess surface water supply to offset groundwater pumping.

The McMullin project proved an excellent example for leaders of the California Water Commission to see the innovative solutions that will bring progress to sustainability efforts in the Central Valley.

Raffle winner claims prized YETI

MAGSA’s raffle contest concluded at the May 13th Open House, where the winning name of the YETI cooler was drawn. The raffle winner Jacob Niederquell grows almonds in the northern area of MAGSA.

Those on MAGSA’s Interested Persons email list were entered into the raffle for a chance to win the YETI cooler.

Thank you to our raffle sponsor, HP Water Systems for the generous YETI cooler donation.

Congrats to our winner, Jacob Niederquell!

FOX26 Town Hall on groundwater will highlight MAGSA sustainability efforts

MAGSA is a co-sponsor of the upcoming Thursday, May 23 FOX26 live Town Hall: Sustainable Groundwater Management Act, and will be represented on the panel by North Fork Kings GSA Board Chair, Mark McKean. Other panelists include:

  • Gary Serrato, North Kings GSA
  • Johnny Amaral, Friant Water Authority
  • Mario Santoyo, San Joaquin Valley Water Infrastructure Authority
  • Thomas Esqueda, California Water Institute

The public is welcome to join the audience in-person at the Clovis Veterans Memorial District or watch from the comfort of their homes. The event will air live on FOX26 from 6:00-7:00 pm and will be streamed live on KMPH.com and the FOX26 mobile app. If you plan to attend as an audience member, it is recommended you arrive around 5:30 pm to secure a seat.

There will be a live audience and viewers will be able to submit questions using a special text number.

Stakeholders indicate priorities on potential effects of groundwater conditions

In an effort to identify and prioritize stakeholder concerns relating to potential impacts that may result from groundwater conditions, MAGSA conducted a survey. The survey asked participants to rank potential effects that can occur across five sustainability indicators (in bold below) from most important to avoid to least important to avoid.

Top responses across the five sustainability indicators for the effects most important to avoid are:

  1. Reduction in groundwater storage: need to drill new wells
  2. Degraded water quality: impact to crop yield, water treatment for domestic use
  3. Land subsidence: damage to wells, damage to infrastructure
  4. Chronic lowering of groundwater levels: irrigation wells becoming unproductive, reduction of well pumping capacity
  5. Interconnected surface water depletion: concern the trees and riparian habitat will dry up

Survey results ensure stakeholder concerns are considered in MAGSA’s Groundwater Sustainability Plan.

The planned pace of sustainability in the McMullin Area will provide early flexibility

The SGMA requires subbasins to become sustainable by 2040. Reaching sustainability objectives will not occur overnight, but rather will require the laying of a foundation at the onset of implementation that yields results in groundwater conditions over the entire 20 year stabilizing period and the 50 year planning horizon. As MAGSA takes stock of current groundwater conditions, the Board must consider the rate at which mitigation will occur.

The orderly implementation of sustainability efforts needs to strike a balance between practicality and intensity. Identified in the Groundwater Sustainability Plan (GSP), the planned rate of mitigation must be approved by Department of Water Resources (DWR). The planned rate needs to set forth a path to achieve sustainability objectives on a feasible timeline.

MAGSA’s technical consultant Lynn Groundwater, Provost & Pritchard, reviewed three alternatives for the rate of mitigation: a constant rate, a phased rate, and a deferred rate. Constant mitigation sets an even pace of 25% improvement every 5 years toward the sustainability objectives. This option is likely acceptable to DWR, but may not be practical as initial projects and management actions will take time to develop. A phased mitigation schedule starts more slowly initially, with an increased rate of progress over time. This rate would allow time to develop management actions and build projects that may not yield the bulk of the intended results until further down the implementation timeline. Deferred mitigation delays 100% of improvement to the last 5 years of GSP implementation, leaving all progress to occur between 2035 and 2040. This rate is unlikely to be accepted by DWR.

The best fit for MAGSA’s sustainability timeline appears likely to be a phased mitigation schedule. Laying the foundation for the service area’s groundwater management will mean heavy lifting on the front end of the timeline to develop the nuts and bolts of projects and management action mechanisms. Phased mitigation grants flexibility to establish this foundation that will yield increased results in later implementation years.

MAGSA developing groundwater level metrics, sustainability criteria considered for individual wells

Setting metrics for groundwater level is underway in MAGSA. At the February 6th Board Meeting, technical consultant Lynn Groundwater, Provost & Pritchard, discussed MAGSA’s methodology for setting the criteria that indicates whether or not sustainable levels of groundwater are met. Known as sustainable management criteria, these levels are guided by historical groundwater level data. The Kings Subbasin coordinated effort has adopted MAGSA’s methodology, with a few variances such as time period of data used.

Sustainable Management Criteria are the SGMA metrics of success. The criteria will include numeric values for groundwater depth. These values will guide sustainability efforts. The first value is the measurable objective: the groundwater depth you must reach and maintain. The second value is the minimum threshold: the groundwater depth you cannot drop below. A range of flexible values, the operational flexibility, will also be determined. The operational flexibility takes into account historical declines and the potential for future drought occurrences. The intent of operational flexibility is to allow groundwater depths to drop for a time (e.g. during a drought) as long as recovery toward the measurable objective follows. 

Using data to determine historical rates of water level decline is important for setting reasonable sustainability objectives. Historical data helps set the objectives. Future data will inform Agency managers of progress occurring toward achievement of those objectives. MAGSA is using historical data beginning 1990-present from wells within its service area. Progress toward the sustainability objectives will be tracked using data collected from the monitoring network of spatially distributed wells.  Moving forward, MAGSA plans to collect groundwater level data from each well at least every March and October. Each well within the network will have its own minimum threshold and measurable objectives against which to measure new data.

Sustainability progress will follow a phased mitigation schedule, starting slowly at first with increased rate of progress over time. This allows time to begin developing management actions and building projects that may not yield the bulk of results until further down the GSP implementation road.  

As Groundwater Sustainability Plan (GSP) draft chapters take shape for internal review, technical consultants are actively seeking public input early on from stakeholders during Board meetings and via the Undesirable Results online survey. The input received prior to the official GSP 90-day public review period allows maximum stakeholder concerns and preferences to be considered and included in early GSP chapter drafts.
