International Rainy and Namakan Lakes Rule Curves Study Board

Background Reports

Review of IJC 2000 Rule Curves

Studies supporting the scheduled rule curve review officially began in 2010, although many other studies done by resource agencies provide additional background data as well - all of these have been reviewed as part of this study. These studies looked at a wide range of potential impacts to the watershed due to the rule curve (flooding damage, wildlife habitat, cultural resources, fish spawning, etc.) and will be used by the Study Board in their evaluation of the 2000 rule curve.

Many of the studies summarized in the reports below are listed in thePlan of Study for the Evaluation of the IJC 2000 Order for Rainy and Namakan Lakes and Rainy River - June 30, 2009.
