Bonner County Lakes Commission Updates

The spring refill of Lake Pend Oreille begins today, April 1. The planned operation for April is to target a lake elevation of approximately 2055 ft by the end of the month. The day-to-day rate of refill will vary based on changing inflows to Lake Pend Oreille. This week, the elevation of Lake Pend Oreille is expected to increase gradually within the 2052-2053 ft range.

Albeni Falls operations during May and June will be set according to observed and forecast conditions in order to manage flood risk. The Corps monitors snowpack and weather forecasts to determine timing to reach the summer operating range of 2062.0 to 2062.5 ft. In a typical non-flood year this summer range is reached in mid to late June. The current seasonal water supply forecast for April-July inflow volume is 88% of average.

Short term modeling forecasts are provided by the Northwest River Forecast Center.  Their projections for Albeni Falls Dam inflow, outflow, and the elevation of Lake Pend Oreille at the Hope gage can be found here:
