Use of the CORE-LOC™ as a Baffling System at the Chicago River Turning Basin Cutoff Wall

Lake Michigan is one of the main sources for water supply of the Chicago Metropolitan area. In 1985, the City of Chicago experienced a severe typhoid epidemic as a result of contaminated water from the river into the lake. In order to prevent further contamination, the city engineers, in 1990, designed a timber cribbing wall that separates the Lake and the River, and a series of locks along the Chicago River that reversed the flow of the river away from Lake Michigan. Over time, the wall started to deteriorate and this had the result of uncontrolled leakage of water from the Lake into the River. As part of the Great Lakes system, the water quality and quantity of Lake Michigan is carefully monitored by the local, state and interstate agencies. In order to stop and control the amount of water taken from Lake Michigan to the Chicago River, a new cutoff wall, a pump station and four sluice gates were designed by Consoer Townsend Envirodyne Engineers, Inc. (CTE-Engineers), for the Illinois Department of Natural Resources - Office of Water Resources. The project location is known as the Chicago River Turning Basin, since it was used in the past for vessel maneuvers.
