Rainy Lake Water Level Adjustment Following Public Consultations


April 10, 2018:  Based on input from various stakeholders received during the first week of March at a meeting in International Falls, MN, and a review on 20 March 2018 of current basin conditions and forecasts, the Water Levels Committee of the International Rainy-Lake of the Woods Watershed Board have directed the operators of the international dam on the Rainy River at Fort Frances-International Falls to adjust the April water level target range for Rainy Lake. The revised target range provides some additional capacity in the lake for early spring snowmelt and rainfall. The revised range is the lowest 10 cm (4 in) of the Rule Curve band, a shift from the standard target of the middle portion of the Rule Curve band.

The standard mid-Rule Curve target remains in effect for the month of April for Namakan Lake.

The Water Levels Committee will continue to monitor the progress of the freshet and make a determination on May water level targets for Rainy Lake and Namakan Lake in late April.
