McMullin On-Farm Flood Capture Expansion Project

The McMullin Area Groundwater Sustainability Agency (MAGSA) has been awarded a $10 million grant by the State Water Resources Control Board through the Prop 1 Stormwater Grant Program to expand the existing McMullin On-Farm Recharge Project located near Helm in Fresno County. The Project is identified in MAGSA’s Groundwater Sustainability Plan and is a key element in a vision developed by MAGSA to achieve groundwater sustainability under the Sustainable Groundwater Management Act through innovative approaches in groundwater banking and crediting.

Project Overview

The infrastructure development resulting from this project will:

Further develop On-Farm Recharge with landowners
