About This Watershed

The Prairie du Pont-Judy’s Branch watershed area is the southern part of the American Bottom, containing communities that have weathered the rise and fall of population, industrial development, and floodwaters. Communities face challenges in maintaining Infrastructure for sanitary sewers and stormwater management.

More information will be coming soon to this page as the planning process progresses.

Funding Opportunities

HeartLands Conservancy received an Illinois EPA grant in late March 2021 to complete a watershed based plan and implementation of pilot best management practices (BMPs) and minor sewer system infrastructure upgrades to alleviate the frequent flooding issues in Cahokia Heights, particularly north Centreville, and surrounding areas.

More information will be available soon.
