Illinois Lake Sturgeon Recovery Program

Lake Sturgeon are a state-endangered species and may not be harvested by any means in the State of Illinois. Due to the decline in Lake Sturgeon populations in most of its native range within the Mississippi River Basin (MRB) over the last century, several MRB states, including Illinois, have implementated recovery and management programs.

The IDNR Division of Fisheries acquired 11,000 Mississippi-strain juvenile Lake Sturgeon with the purpose of stocking Lake Sturgeon in the Illinois portions of the Mississippi River and its tributaries in 2023. The mission of the Illinois Lake Sturgeon Recovery Program is to re-establish a sustainable population of a state-endangered species in suitable waters within the State of Illinois. If this plan is successful, it could provide a new sport fishing opportunity to Illinois anglers in the future. Read more about this program here: Lake Sturgeon Recovery Program.

Stop the Spread of Invasive Species

Remove, Drain, Dry: As the boats come out of storage, we'd like to remind you to be aware of invasive species that pose a threat to our lands and waterways. To fight the spread of aquatic invaders, the IDNR is asking residents to "be a hero transport zero." The best way to stop the spread of invasive species is to remove, drain, and dry your boats after use in any Illinois waterway. Learn more here.
