About this file

This is a survey map document for the Illinois Department of Natural Resources (DNR) Waterfowl Helicopter Surveys contract covering 2026-2028. The map illustrates the general survey areas across Illinois where aerial inventories of waterfowl populations will be conducted. The survey encompasses 64 designated sites distributed across four regional survey areas: Northeast Illinois Waterfowl Survey Area (NEIL), West-Central Illinois Waterfowl Survey Area (WCIL), Central Illinois Waterfowl Survey Area (CIL), and Southern Illinois Waterfowl Survey Area (SIL). The sites include a mix of wildlife management areas, fish and wildlife areas, state natural areas, state recreation areas, lakes, and other waterfowl habitats. Notable survey locations include the Kankakee River, Illinois River, DesPlaines River, Crab Orchard National Wildlife Refuge, and numerous lakes and marshes throughout the state, providing comprehensive geographic coverage from the northern border near the Kankakee River to southern locations such as Cache River and Horseshoe Lake.

The document serves as a reference map identifying the spatial distribution and general locations of all sites subject to aerial inventory during the contract period, with specific detailed maps available for each of the four regional survey areas (NEIL, WCIL, CIL, and SIL). This foundational planning document establishes the scope of the waterfowl survey program and indicates the breadth of Illinois territory requiring helicopter-based aerial survey services throughout the three-year contract term.
