Reservoir Operations Pilots

Through the Reservoir Operations Pilot Initiative, Reclamation uses modeling and forecasting tools to identify ways to increase flexibility in reservoir operations to support optimal water management.

2021 Pilot Studies

In June 2021, Reclamation selected six new Reservoir Operations Pilot Studies to evaluate approaches and potential operating alternatives to increase flexibility in reservoir operations to address risks from changes in the timing and volume of snowpack and runoff, changing water demands, reservoir evaporation, and risks from water supply shortfalls due to drought or competing demands.

Project Descriptions

2015 Pilot Studies

In 2015, Reclamation selected five pilot studies to identify possible improvements to reservoir operations. The results from these pilots are posted on this webpage, as they become available. See links to Bulletins summarizing pilot results and to the full reports.

Current Status

Reclamation has identified six new 2021 Reservoir Operations Pilot projects for funding following Round 1 selections.

Proposed Calendar

A new Call for Proposals is anticipated in fall/winter 2022.
