The Snake River can be productive and tricky for anglers during spring. There's a tight window from when the water starts warming up and the fish get active, but before the snow melt comes rushing downstream and swells the river and drops the temperature.
Idaho Power announced flows won't change for a while.
"Flows in the mid-Snake are expected to remain at or slightly below current levels through March as reservoirs in eastern Idaho continue to fill," Idaho Power officials said.
Most of the reservoirs on the Upper Snake are more than three-fourths full. Updated information from the U.S. Bureau of Reclamation is available here.

In Hells Canyon, the elevation at Brownlee Reservoir is being lowered to make room for potential higher flows later in the spring. These flood control measures are directed by the U.S. Army Corps of Engineers. As of Tuesday, Feb. 17, Brownlee was at 2,057 feet, which is 20 feet below full. The current flood-control target is 2,055 feet by Feb. 28.
The target level for the end of March will be adjusted after a new river-level forecast is issued March 5. All maintained boat ramps on Brownlee Reservoir remain usable at the current level.
