Namakan outflow reduced

The Water Levels Committee of the International Rainy-Lake of the Woods Watershed Board has directed the dam operators on Namakan Lake to target the upper rule curve rather than the middle portion of the band.
This step was taken to reduce inflow to Rainy Lake in order to help increase its rate of decline.

The outflow from the Kettle Falls dam was reduced Sunday.
As of Monday, the average level of Namakan Lake was just below the upper rule curve.
Conditions are being monitored closely in the wake of recent precipitation.
Should the inflow to Namakan Lake rise significantly above the current outflow, it may be necessary to increase outflow to maintain the lake level near the upper rule curve.
