MID provides irrigation water to approximately 3,100 agricultural customers who irrigate close to 60,000 acres of permanent and annual crops alike. Water is transported to area farms via MID’s 208 miles of canals and pipelines that operate on a gravity flow system.  Surface water from the Tuolumne River flows downhill all the way from the beginning (MID’s Upper Main Canal at La Grange) to the end of MID’s canal system (several locations where there are drains into the San Joaquin, Stanislaus and Tuolumne rivers).

2019 Groundwater Replenishment Plan

The 2019 Groundwater Replenishment Plan (GRP) is a voluntary plan that allows MID to deliver surface water to any eligible landowners outside of MID's irrigation boundaries, but within MID's sphere for influence for the purposes of groundwater replenishment.
