Landowner and stakeholder participation will help create a fair groundwater pumping cap program

Learn about upcoming local groundwater supply changes and how groundwater pumping caps will change landowners’ water management strategy. The Greater Kaweah GSA will be hosting a webinar in December and workshop in January to discuss pumping caps impacting landowners in the area.

The Greater Kaweah GSA Board is conducting two initial public events to provide landowners an opportunity to learn about the proposed pumping cap policy leading to a formal 90-day public comment period scheduled to conclude in April 2022. Landowners can prepare for a future pumping cap by getting involved now. Attend upcoming meetings, talk with staff and stakeholder committee and Board members, and sign up for e-updates (form to the right of this page). The Board is dedicated to navigating SGMA together as a local community, and we look forward to your input.

💧 Groundwater Pumping Caps will Change Your Groundwater Management Strategy

Greater Kaweah GSA Pumping Caps

The Greater Kaweah GSA is developing a draft groundwater pumping cap proposal in anticipation of implementing a full pumping cap program in October 2022, however, emergency action may be required sooner if drought conditions continue.

The pumping cap program will change the way landowners manage the use of their groundwater supply by limiting the amount of groundwater that can be used over a period of time. The GSA Board’s goal is to develop a program that provides for equality and flexibility of all landowners in the Greater Kaweah GSA service area.

Why a Pumping Cap is Needed

Due to an oversubscribed dependence on groundwater in the Kaweah Subbasin, long-term analysis shows groundwater levels declining over the past 20 years and earlier. For the years 1997 to 2017, the region has experienced average groundwater declines in the range of 100 feet. The Kaweah Subbasin is currently estimated to have an annual average overdraft of approximately 80,000 acre-feet per year (an acre foot of water equals about 326,000 gallons of enough water to cover a football field 1-foot deep).

Due to the last two severely dry years, groundwater pumping has persisted and much more has been pumped from the aquifer than was replaced. This increased pumping has created a larger shortfall in groundwater levels than anticipated in the Greater Kaweah’s Groundwater Sustainability Plan adopted in January 2020. Although the Plan calls for a gradual reduction of the overdraft, pumping over the last two years requires more immediate actions to be taken through demand-side management if the short and long-term goals as submitted to the State are to be met. Compliance with SGMA is not optional and is best accomplished without State intervention.

The Sustainable Groundwater Management Act (SGMA) is a State law that requires groundwater subbasins to achieve sustainability goals by 2040 through management and balance of groundwater supplies. SGMA has sever consequences to landowners if its requirements are not met, including more costly state intervention. Local management is needed to more equitably source this valuable resource for our local community for years to come. SGMA affects ALL users of groundwater.

Compliance with SGMA is not optional and is best accomplished locally. The Greater Kaweah GSA Board is dedicated to navigating SGMA together as a local community.
