Hourly Release Estimates

24-hour Water Release Info






J.C. Boyle Powerhouse flow forecasts have been discontinued for the winter and will resume in May of 2014.

Daily variations in flow into J.C. Boyle Reservoir during the fall and winter months and variable flow releases from Iron Gate dam can result in numerous operational schedule changes in one 24 hour period. This may cause erroneous or misleading postings on this page. Flow forecasts below J.C. Boyle powerhouse will resume in the spring of 2014 once river flows and the electric customer load requirements of the project are again stable enough to forecast future days’ release levels and timing of generation.

Real-Time flow information below J.C. Boyle Powerhouse is available from the U.S. Geological Survey.
