Army Corps of Engineers requests comments on Cedar Lake aquatic ecosystem restoration feasibility study

Published July 7, 2016

Chicago (July 7, 2016) – The U.S. Army Corps of Engineers (USACE), Chicago District, has released for public review and comment the Cedar Lake Aquatic Ecosystem Restoration Feasibility Study, Cedar Lake, Ind., Draft Feasibility Report and Integrated Environmental Assessment. 

   The draft feasibility report, completed in collaboration with the nonfederal sponsor, the Town of Cedar Lake, describes an ecosystem restoration project that could be implemented within the 781-acre glacially formed Cedar Lake as well as along Founders Creek, a tributary to Cedar Lake. This report addresses the need to restore an ecosystem historically degraded by surrounding watershed practices and activities. 

   Features of the proposed project, the locally-preferred plan, described in the draft report include restoration of approximately 35 acres of emergent and 95 acres of submergent aquatic plants within the littoral (near-shore) zone, reestablishment of a native fish community, rerouting of Founders Creek to its historic connection with Cedar Lake, physical substrate restoration through removal of 263,000-cubic yards of sediment, chemical substrate restoration through alum dosage over 400-acres of lake bottom, and implementation of institutional controls.

   With this restoration, resident and migratory birds, fish, aquatic macroinvertebrates, and other native wildlife are expected to benefit. Additionally, this project has the potential for supporting the following state endangered species and species of special concern: Black-crowned Night-heron, Marsh Wren, Blanding’s Turtle, Northern Leopard Frog, and Common Mudpuppy. There may also be suitable summer nursery habitat for the federally-endangered Indiana Bat and federally-threatened Northern Long-eared Bat within the general area.

   The report is available online at USACE is accepting comments on the report through August 8, 2016. Comments may be submitted by e-mail to; or mailed to: U.S. Army Corps of Engineers, Chicago District, 231 S. LaSalle Street, Ste. 1500, Chicago, IL 60604, ATTN: Cedar Lake Draft Report. Emailed comments must be received by August 8, 2016, and mailed comments must be postmarked by August 8, 2016. Questions should be directed to the Public Affairs Office at (312) 846-5330.
