INTERNATIONAL FALLS, MN and FORT FRANCES, ON, Oct. 10, 2023 /CNW/ - The International Rainy-Lake of the Woods Watershed Board (IRLWWB) Water Levels Committee (WLC) released its 2022 Post-Flood Report: A Report on High Water Levels in the Rainy River Basin.
In the spring and summer of 2022, the Namakan Chain of Lakes and Rainy Lake reached some of the highest water levels on record. The flood was due to record precipitation in April and May. The intensity and longevity of the spring precipitation caused flows in the tributaries of the Rainy River watershed to remain at high or close to peak levels from late April to mid-June.
The Post-Flood Report focuses on Rainy and Namakan Lakes and covers the following topics: roles and responsibilities shared by the International Joint Commission (IJC), IRLWWB, and WLC within the Rainy River-Lake of the Woods watershed; hydrologic conditions that led to the extreme flooding in the Rainy River basin; activities and decisions of the WLC in 2022; the role of rule curves during flood events and what would have happened if the High Flood Risk Rule Curve (HFRRC) on Rainy Lake was implemented in 2022; and a summary of public engagement and what the WLC heard throughout the flood event and August 2022 public listening sessions.
