Great Lakes Water Levels Special Report in Milwaukee Journal Sentinel

The Milwaukee Journal Sentinel recently published a very informative and interesting series on Water Levels in the Great Lakes called Uncharted Waters.

Part 1
Does Lake Michigan’s record low mark beginning of new era for Great Lakes?
At least 150 years of rhythmic pulses in Lake Michigan’s water levels appear to have shifted abruptly with loss of winter ice.

Part 2
Water flushes through a greatly widened drain below Lakes Michigan, Huron
Every time dredging widened and deepened the hole at the bottom of the lakes, the federal government was supposed to engineer a fix to maintain water levels – but it never did.

Technical Resources Page Added to GreatLakesCoast.org

A new page has been added to the Great Lakes Coastal Flood Study website in the menu on the left called Technical Resources. The Technical Resources page contains links to data and reports of interest to engineers and other technical stakeholders interested in the Great Lakes Coastal Flood Study.

As of this posting, there is a link to high-resolution bathymetric and topographic LiDAR data on NOAA’s Coastal Services Center Digital Coast website. In June 2012, additional data links will go live, including the C-STORM wave and storm surge database (containing all the wind, wave, pressure, ice and water level data for the Great Lakes basin) and the Great Lakes Oblique Photo Viewer (containing all the coastal oblique photographs of the Great Lakes shoreline).

The Technical Resources page also currently houses links to U.S. Army Corps of Engineers reports relevant to the Great Lakes Coastal Flood Study, as well as a link to the FEMA Great Lakes Coastal Guidelines, Appendix D.3 Update at fema.gov, which includes information on the 60-day public comment process that starts today.

All stakeholders are invited to review and comment on this draft guidance. See FEMA’s webpage for e-mail address for submission of comments.

International Upper Great Lakes Study Progress Report

In 2007, the International Joint Commission launched a five-year study to look at future water levels in the upper Great Lakes and the options for regulating those levels to support the region’s economic and environmental interests. In the entire upper lakes basin, water levels are currently influenced through a regulation plan at the St. Marys River control structures at Sault Ste. Marie, where Lake Superior outflows have been regulated since 1914.

Please view the Progress Report from the International Upper Great Lakes Study at this link
