Reservoir Level Update
This morning the reservoir level was two inches below the spillway (-2 inches) which is two inches higher than yesterday morning. The consultant completed the IFIM studies they were performing this week shortly before noon yesterday so we resumed releasing flow based on the estimated inflow for the previous day. Yesterday's estimated inflow was 409 cfs (264 million gallons) which means we only have to release 190 cfs (123 million gallons) today. After subtracting an estimated 45 cfs for raw water withdrawals this still leaves 174 cfs (112 million gallons) that will be stored in the reservoir. This should raise the reservoir level about 1.5 inches today. Therefore the reservoir level should exceed the spillway level sometime tomorrow at the latest. Once water is flowing over the spillway the hydro-electric facility can resume operation and generate power with the water flowing to the downstream portion of the river.
