Fish Status



Bluegill are present, but little is known about the population in this lake. No bluegill have been collected during the last 3 years of trap netting surveys. An electrofishing survey planned in 2020 should effectively sample the bluegill population in Mallard Lake. Site Regulation: 25 fish daily limit.



No channel catfish have ever been collected during sampling at Mallard Lake. However, IDNR has observed anglers catching channel catfish in the past. Site Regulation: 6 fish daily limit.



Mallard Lake appears to have a decent crappie population consisting of both black and white crappie. Although the number of fish collected at this lake during surveys is typically low, many of the crappie collected are over 9 inches in length. Site Regulation: 25 fish daily limit.



An electrofishing survey is the best way to analyze the largemouth bass population in a lake. A nighttime electrofishing survey is planned for spring 2020, as night shocking is the best way to sample bass in clear lakes. Trap nets are generally ineffective at sampling bass, but bass over 18 inches have been collected in previous trap net surveys. Site Regulation: Creel limit of 5 fish under 14" and one fish over 18"; there is a protected slot of 14-18" (no possession).

Location: Pyramid State Park is located south of Pinckneyville in Perry County. Mallard Lake is located on the Denmark Section of Pyramid State Park. The Denmark Section is accessed off of Pyatt-Cutler Road. From State Route 127 head west on Pyatt-Cutler Road. About 7 miles west of Pyramid State Park turn south into the Denmark Section.

Description: Mallard Lake is located on the Denmark Section of Pyramid State Park. Facilities at this 75-acre strip cut lake include a boat launch, floating dock, and bathrooms.

History and Status of the Sport Fishery: All fishery information is based on spring trap netting surveys thus far. A nighttime electrofishing survey should effectively sample the bass population and better describe the fish community in this lake.
