Upper Lakes Plan of Study Available

The IJC's Upper Lakes Plan of Study Revision Team has updated the 2002 plan of study to investigate improvements to Lake Superior outflow regulation. This document is available on the IJC Web site.

In May 2005, the IJC appointed the Upper Lakes Study Revision Team to expand the 2002 plan of study to include an investigation of past and on-going physical changes in the St. Clair River. The St. Clair River was incorporated into the plan of study because of the impacts physical changes might have on the water levels of Lakes Michigan-Huron, on Lake Superior outflow regulation, and the IJC's Orders of Approval governing Lake Superior outflow regulation.

The latest edition of the Monthly Water Level Bulletin (December 2005) found at: http://chswww.bur.dfo.ca/danp/ contains the water level forecast for January to June 2006.
