About this file

This is a survey schedule document for the Illinois Department of Natural Resources (DNR) waterfowl helicopter survey contract covering the 2026-2027 fiscal year. The schedule outlines survey operations across four geographic zones: Northeast (based at Morris and Marion Airports), South (based at Canton Airport), and West-Central (based at Morris Airport). The contract encompasses multiple survey types including primary surveys, alternate survey dates, shotgun deer season operations, check station activities, and midwinter surveys. The schedule spans from October 2026 through January 2027, with specific survey dates allocated for each zone and alternates provided for weather or operational contingencies. Key operational dates include the North and Central Zone openers in late October 2026, the shotgun deer season running through December 2026, and the midwinter survey scheduled for January 2027. The document identifies holidays affecting operations including Columbus Day, Veterans Day, Thanksgiving, Christmas, New Year's Day, and MLK Holiday, with corresponding no-survey periods noted.

The schedule reflects a structured operational calendar integrating multiple survey methodologies and seasonal hunting seasons across three airport locations serving different geographic regions. The document appears designed to coordinate helicopter-based waterfowl survey activities with deer hunting seasons and other wildlife management operations, ensuring comprehensive data collection throughout the specified contract period while accommodating operational constraints and holiday interruptions.
