Marie, Michigan, during a visit October 22. Spellmon, Command Sergeant Major Patrickson Toussaint and several others toured the facility and the New Lock at the Soo project currently under construction. The new lock will replace two older, smaller decommissioned locks and be about the same size as the 1969-built Poe Lock. It is 1,200 feet long, 110 feet wide and 32 feet deep. The Poe is the only lock that can handle the largest freighters used on the upper Great Lakes. About 80 million tons of commercial commodities worth an estimated $500 billion pass through the Soo Locks each year.

Glaciers covered most of the Great Lakes basin approximately 14,000 years ago. During the glacial retreat, the glaciers eroded rock and soil and carried it along with moving ice to the glacier edge where it was released from the melting ice and deposited as till, a mixture of sand, silt and clay.

Grand River Draft EIS Notice of Intent/NEPA Scoping Meeting

3/19/2019
SUMMARY: Pursuant to the requirements of the National Environmental Policy Act (NEPA) of 1969, as implemented by the Council on Environmental Quality Regulations, the U.S. Army Corps of Engineers (USACE) Detroit District, announces its intent to conduct public scoping and solicit public comments to gather information to prepare a draft Environmental Impact Statement (EIS) on behalf of the Great Lakes Fishery Commission (GLFC) related to the proposed Grand River Habitat Restoration and Invasive Species Control Project in Grand Rapids, Michigan. The project must provide a means to block sea lamprey from moving upstream, as this invasive species is currently blocked by the existing 6th Street Dam in the Grand River, must maintain or reduce the current risk of flooding upstream, and must provide for fish passage into upstream areas. If implemented, the project is expected to adversely impact existing healthy mussel population, which includes the federally-listed endangered scaleshell and snuffbox mussels as well as a number of state listed mussel species. DATES: Comments for consideration in the development of the scope of the NEPA draft EIS are due no later than May 15, 2019. Comments may also be made at the public scoping meeting as noted below. All comments and materials received, including names and addresses, will become part of the administrative record and may be released to the public. ADDRESSES: The public is invited to submit written comments at the meeting and/or to Mr. Charles A. Uhlarik,Department of the Army, U.S. Army Corps of Engineers, Detroit District, Environmental Analysis Branch, 477 Michigan Avenue, Detroit, MI 48226 or via email to: Comments-Grand-River@usace.army.mil.
