Friends … the latest NOAA/NWS weekly forecasts for Rainy and Namakan Lakes were released today. It’s heartbreaking to deliver this message.
* Rainy Lake is projected to rise 11-13 more inches over the next week, and rise through mid-June and likely break the all-time record high-level of 1950.
* Namakan Lake is projected to rise 5-7 inches more next week, and possibly continue to rise into mid-June. At this rate, Namakan Lake will reach the all-time record high level set in 1916.
* A wet weather pattern is projected for Sunday through Wednesday that could drop 1 to 3 inches of rain throughout the basin. This is driving the above forecasts.
* Once peak levels have passed, it will take a long time (weeks) for lake levels to fall to anything close to normal summer levels. Areas experiencing flooding and performing mitigation measures should expect to deal with high water levels for the foreseeable future.

None of this is good news. There are signs, however, that levels will crest in the coming weeks. The headwater streams and large tributaries have peaked and are now on the decline due to dryer weather. But until net inflows from upstream sources fall below outflows through Rainy River and the dam, unfortunately we remain on the path to higher water levels for now.
