Upper Des Plaines River

Des Plaines River Phase I Project

The Des Plaines River has a long history of flooding that has caused significant damage and economic losses. The maximum flood of record in September 1986 caused an estimated $35 million in damage to 10,000 dwellings and 263 business and industrial sites. More than 15,000 residents were evacuated from the flooded area. In this area of 33 municipalities along 67 miles of river in two counties, severe impacts to the area transportation networks were also identified and a large proportion of project benefits accrue to motorists. The Phase I Project is authorized under the Water Resources Development Act of 1999, Section 101 (b) (10), August 17, 1999.

The project has six structural features:

  1. Levee 37
  2. Big Bend Lake Reservoir Expansion
  3. VanPatten Woods Lateral storage area
  4. North Mill Creek Dam Modification
  5. Buffalo Creek Reservoir Expansion
  6. Levee 50

Des Plaines River and Tributaries Phase II Study

The Northwest Municipal Conference and the Army Corps of Engineers are working with state and federal agencies, local and national groups to find forward-thinking solutions that meet the needs of all concerned. Accurate and timely information is critical to the effective resolution of the many issues associated wit the Phase II project. The Phase II project is authorized under the Water Resources Development Act of 1999, Section 419, August 17, 1999.

The Des Plaines River starts in southeast Wisconsin and flows south into northeast Illinois. It has a long history of flooding that has caused significant economic losses. The Phase II study provides for formulating projects that reduce damages on both the main stem and its tributaries because the study is specifically exempt from the Army Corps restrictions regarding 800 CFS. Additionally, the range of alternative solutions to be investigated is very broad. Potential sites in both Illinois and Wisconsin which address the interests of flood damage reduction, environmental restoration and protection, water quality, recreation and related purposes will be included.

The Upper Des Plaines River and Tributaries, Phase II Feasibility Study can be found at the U.S. Army Corps of Engineers' website.
