The Senior Canyon Reservoir has existed in some capacity since 1929, but it wasn’t until the early 1960s that the company hired premier geotechnical engineer Julian Hinds to create the dam and reservoir as it exists today.  The reservoir holds 80-acre feet of water, all of which is designated for agricultural use. The company is currently working on expanding the reach of reservoir water so the reservoir can service orchards across the East End and lessen demand on the company’s potable water supply.  Potable water is stored in the Thacher tank and a small portion of the company’s East End orchards rely on that water.  The company’s main headquarters also sit on the edge of the reservoir.

Each year California’s Department of Water Resources, Division of Safety of Dams, inspects the earthen dam to ensure the dam’s safety and integrity.  SCMWC and adjacent landowners are required to mitigate any recommendations outlined in the report.  In addition, Senior Canyon is in the process of developing an inundation map and evacuation plan as required by State law.
