May 4th, 2022 Update

Rainy Lake friends, inflows to the lake are continuing to rise, approaching 1,200 cubic meters per second. Inflows exceed outflows by about 300-400 cubic meters per second which translates to 1 – 1.2 inch rise per day. Given the hydraulic limitations of upper Rainy River and dam, lake outflows can not match current inflows until lake levels reach about foot above the all gates open level. Below I’ve charted historical data showing the current situation. At this point it may be prudent to prepare for high water in coming weeks.

I’m aware the professionals at the IJC and local advisory groups are monitoring this closely, and they have access to the latest data. We should be watching for any advice that may be forthcoming from those groups
