Lake and River Forecasts

Lake Level Forecast

A graph showing the US Bureau of Reclamation's forecast for lake elevation at the 90% confidence level (dark blue) and the 50% confidence level (light blue) is available on the Trinity River Restoration Program's website.

Last year, the 50% confidence level was quite accurate. Lake outflow determinations are based upon the 50% confidence level.

Current Restoration Flow Release Schedule -- This is the water released from Lewiston Dam, not the total release out of Trinity Dam. The Central Valley Project gets up to 51% of annual inflow and the Trinity River gets 49%. But, in past years, the Trinity River has gotten extra water for the Ceremony Boat Dance in August and Late-summer Augmentation Releases.
