RAINBOW TROUT

Trout are stocked at the Visitor Center Lagoon in the spring and fall.

Location: This 104.5 linear park spans 5 counties (Rock Island, Henry, Bureau, Lee and Whiteside). Construction began on the Canal in 1890 and was completed in 1907. The Canal became a State Park in 1970. The Visitor's Center is located south of Interstate 80 just off Highway 40.

Description: Spanning 5 counties, the Canal is 925 acres with an average depth of 5 feet, is 104.5 miles long, and averages about 90 feet wide. The majority of the Canal is accessible to bank angling.

All boats should try to operate with “no wake” to protect the shoreline from wave erosion. The Hennepin Canal has 10 concrete boat ramps and 1 gravel boat ramp. There is no concession on the canal, however there are many cities near the Canal that offer bait, food and supplies.

History and Status of the Sport Fishery: The fishery is managed by annual species-specific surveys and stocking. The Hennepin Canal receives an annual stocking of Largemouth Bass and Sauger. Trout are stocked at the Visitor's Center Lagoon in the spring and fall.
