Ceres Main Regulating Reservoir

As part of TID’s conjunctive management program, the District is constantly looking for ways to enhance our surface water and groundwater interaction. A regulating reservoir provides multiple benefits in a gravity-based irrigation distribution system. It supports water conservation by stabilizing flow rates in the system downstream of the reservoir and by capturing water that is normally lost to surrounding rivers, allowing that water to remain stored for later use. Stable flow rates and increased water supply reliability, coupled with faster response times to customer demands, provide vast improvements in customer service for growers served by the reservoir.

Quick Facts

  • $10 million – Cost of the entire project
  • 36 Acres – Footprint of the regulating reservoir
  • 10,000 Acre-Feet – Anticipated annual water savings from the project
  • 220 Acre-Feet – Operational storage capacity of the regulating reservoir
  • Designed and constructed in-house by TID staff

Project Benefits

  • Reduce groundwater pumping
  • Support water conservation
  • Improve water quality
  • Capture excess water
  • Improve operational flexibility
  • Improve customer service

Site Location

The Ceres Main Regulating Reservoir captures flows from the Ceres Main Canal and then pumps the stored water back into the Ceres Main Canal and Lower Lateral 3 canal to enhance deliveries to the canal system downstream of the reservoir.

This strategic location along the TID irrigation system benefits approximately 25,000 acres below the reservoir.
