Spring drawdown begins at Lake Roosevelt

BOATING — The level of Lake Roosevelt is about 1274 feet today, and it's begun a steady downward trend to make room for spring runoff.  But Columbia River dam operators don't expect the drawdown to be nearly as severe as in recent years, having less impact on boaters and anglers.

Grand Coulee Dam is being operated to reach the flood control elevation of 1258.5 at the end of the month, according to the U.S. Bureau of Reclamation. 

Lake levels are expected to decrease 1 to 1.5 feet a day and spill over the drumgates will be intermittent through the rest of the month in order to reach the flood control elevation target.

Lake Roosevelt water levels to be steady

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.

Roosevelt lake levels on downward trend

RESERVOIRS — The level of Lake Roosevelt was 1278.4 feet today in a drop that was predicted to be around 1 foot in a 24 hour period.

The elevation of Lake Roosevelt is expected to drop by about 1/2 foot per day over the next week. It is antipated the elevation will be about 1274 by the end of next week, according to the Bureau of Reclamation. 

Currently, Grand Coulee Dam is being operated to meet the minimum tailwater requirement of 13.5 feet below Bonneville Dam for chum.

The flood control elevations for Lake Roosevelt have changed based on the February water supply forecast. January turned out to be a dry month and currently the forecast does not call for significant precipitation into the near future. The water inflow forecast from January - July into Lake Roosevelt is 89% of average.

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:

  • Feb. 28 - 1290 feet
  • 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.

  • January 31 - 1290 feet

  • February 28 - 1290 feet
