Lockport Prairie Nature Preserve

The Lockport Prairie Nature Preserve is located in Will County near the village of Lockport. The site is 365 acres in size, and the majority of it is wetlands.  Achange in the surface and groundwater hydrology in terms of the water quantity and quality (chemistry) has adversely impacted several threatened and endangered (T&E) species. Lockport Prairie supports numerous rare and uncommon plant and animal species. Nearly 400 native plant species have been identified at Lockport Prairie, and at least nine of those are identified as threatened or endangered species.


Section 206, Water Resources Development Act 1996, as amended (Continuing Authority, Section)
