Project: Westside Regional Drainage Plan Implementation

Description: The Westside Regional Drainage Plan will meet existing and future water quality criteria for salt, boron and selenium by implementing projects that manage, reduce, or eliminate agricultural drainage discharge through the Grasslands Bypass Project. This Project is split into 3 subprojects: Project 1 – Reuse Land Expansion; Project 2 – Development & Conveyance; and Project 3 – Source Control Projects. The collective objective of these projects is to reduce the discharge of subsurface agricultural drainage, and associated constituents contributing to water quality, into the San Joaquin River by increasing drainage reuse potential in the and eliminating sources of drainage discharge. The Project will utilize existing agricultural drainage as a source irrigation water for sustaining salt-tolerant crops, and will line existing drains and canals to prevent the continual seepage from these conveyances. The Project will require acquisition of fallowed agricultural properties which will be developed to sustain salt-tolerant crops including “Jose” Tall Wheatgrass and pistachios for drainage reuse, potentially increasing drainage reuse capacity by up to 11,000 afy. Additional areas within the existing San Joaquin River Improvement Project (SJRIP), up to 870 acres, will also be developed to support salt-tolerant crops and contribute to the aforementioned drainage reuse capacity. Furthermore, historical sources of seepage from drainage conveyances will be remedied by lining several miles of drains and canals, and will eliminate approximately 800 afy of drainage seepage.

Reference Number: 3860-P84-705

Implemented By: Panoche Drainage District

Objective: Reduce/eliminate discharge of subsurface agricultural drainwater to the SJR from the Grassland Drainage Area. Improve regional management of subsurface agricultural drain water. Reduce the production of subsurface drain water from seepage.
