Water Supply Operation

Pardee and Camanche Reservoirs are

  • perated in a integrated manner to

meet a myriad of obligations:

– Water supply – Flood Control – Streamflow Regulation – Fishery Requirements – Obligations to Downstream Diverters – Recreation – Hydropower Generation

Project Objectives and Need

  • Continue the ability to reliably meet existing and future water

demands within EBMUD’s service area in a cost-effective manner

  • Have sufficient supplies to meet projected increases in overall

demand for water

  • Meet peak demands
  • Maintain operational flexibility to meet demands following

prolonged droughts or catastrophic events

  • Meet water quality and flow commitments to protect ecosystem

and anadromous fish

Proposed Project

  • Extend existing Permit 10478 to the year 2040 to allow

EBMUD additional time to apply the water to beneficial use

– 40-year time frame based on planning horizon of the 2040 Water Demand Study and land-use plans – No new water rights authorizations – No new construction – No change in operations

Summary of Significant Impacts

  • Impact FISH-1: Reduced migration habitat for adult fall-run

Chinook salmon and steelhead

– Potentially Significant; Less than Significant with Mitigation

  • Impact AG-1: Potential reduction of surface water supply for

agricultural use by senior water rights holders

– Potentially Significant; Less than Significant with Mitigation

Conclusions

  • No significant and irreversible changes identified under the

Project

  • Two potentially significant impacts identified under Project are

reduced to less than significant with mitigation

– Reduced adult migration habitat for fall-run Chinook and steelhead – Reduced access to water supply to JVID
