RESERVOIRS — The level of Lake Roosevelt was 1274.85 at midnight last night and is expected to
slowly rise over the next week.
The Bureau of Reclamation anticipates the elevation for the end of next week will be in the 1277 - 1279 range.
Currently, Grand Coulee Dam is being operated to meet power demand and also the minimum tailwater requirement of 13.5 feet below Bonneville Dam for chum.
The flood control elevations for Lake Roosevelt have been issued based on the January water supply forecast. These levels are the maximum elevation for Lake Roosevelt. Other factors such as power demand can result in elevations under the flood control elevations.
The flood control elevations are as follows:
January 31 - 1290 feet
February 28 - 1290 feet
March 31 - 1266.4 feet
April 30 - 1235.7 feet
These elevations can and probably will change with the February water supply forecast.
This is only a prediction and can change due to weather events, power demand or other unforeseen power emergencies.
