Public Comment on Recommended Changes to the Rainy and Namakan Lakes Rule Curves

The comment period closed on June 1, 2017. Thank you for your comments. Comments have been posted to the website and can be viewed here.

The Rainy-Namakan Lakes Rule Curves Study Board was appointed in the fall of 2015 to make scientifically supported recommendations to the IJC for modifying or retaining the 2000 Rainy and Namakan Lakes rule curves after reviewing the wide range of hydrologic, hydraulic, economic, cultural and environmental factors.

The Study Board is completing its work, and has released to the public and all interested parties, its draft report to the International Joint Commission, with its findings, recommendations and rationale. The Study Board is welcoming comments on its draft report until midnight June 1, 2017.

Below you will find a button to submit comments, and on the right of this page under Document Library you will find links to the draft report, “Managing Water Levels and Flows in the Rainy Basin”, a guide to understanding the Shared Vision Model, and the Weight of Evidence matrix table used to review the 2000 Rule Curves. Lastly, there is a story map below which holds a wealth of background information on the study and Rainy-Namakan system. As well, there are two videos that the Study Board and IJC produced to explain the basic hydrology of the outlet of Rainy Lake and the control function provided by the dam between International Falls, Minnesota and Fort Frances, Ontario.
