RESERVOIRS -- The level of Lake Roosevelt was 1275 today and likely will be stable for a while.
The U.S. Bureau of Reclamation antipates the elevation will be in the 1275 -1276 range through the next week. Currently, Grand Coulee Dam is being operated to meet the minimum tailwater requirement of 11.8 feet below Bonneville Dam for chum.
The flood control levels are the maximum elevation for Lake Roosevelt. Other factors such as power demand or supplying water downstream for fish can result in elevations under the flood control elevations.
The flood control elevations are as follows:
- March 31 - 1282.3 feet
- April 30 - 1260.8 feet
These elevations can and probably will change with the March water supply forecast.
This is only a prediction and can change due to weather events, power demand or other unforeseen power emergencies.
