International Joint Commission invites public comment on Upper Great Lakes water levels study via teleconference


The International Joint Commission (IJC) announced today that it is inviting public comment via a bilingual public hearing by teleconference on the final report of its International Upper Great Lakes Study Board, Lake Superior Regulation: Addressing Uncertainty in Upper Great Lakes Water Levels.

The teleconference will be held at 7:00 p.m. (EDT) on September 19, 2012 and will provide an opportunity to be heard for those who were not able to attend one of the 13 public hearings that the IJC conducted in upper Great Lakes communities during July 2012.  The deadline for comments has also been extended to September 30, 2012.

The report examines whether the regulation of outflows from Lake Superior through the compensating works and power dams on the St. Marys River at Sault Ste. Marie might be improved to take into consideration the evolving needs of users on Lakes Superior, Huron, Michigan and Erie. The report also examines the potential future impacts of climate change, a management strategy to better anticipate and respond to future extreme water levels, the feasibility and implications of restoring water levels in lakes Michigan-Huron and multi-lake regulation and its impacts throughout the Great Lakes-St. Lawrence system. A presentation on the study findings, as well as the full Study Board report,supporting documents and peer review are available online. 

Participants may join the teleconference on either of the following lines and are encouraged to dial in 10 minutes before the 7:00 p.m. (EDT) start time:
