Fish Status |
Poor | The Bluegill population size structure is poor. Very few Bluegill over 7 inches have been collected. | |
Average | A low density population of Channel Catfish exists in the lake. Five were collected during the 2021 fall netting survey, ranging in size from 2 to 6.5 lbs. | |
Good | Very few crappie have ever been collected from Mallard Lake. This lake is very steep-sided which limits the effectiveness of trap nets, which are considered the best gear for sampling crappie. Although little data has been collected, anglers have reported that a quality fishery exists. | |
Very Good | Electrofishing is now a suitable sampling tool at this lake thanks to modernized equipment that can effectively stun fish in high conductivity water. Therefore, an electrofishing survey was conducted during April of 2021. The survey was conducted at night due to the deep, steep-sided nature of the lake, which can limit the efficiency of electrofishing during daylight hours. Results of the survey indicate a quality bass fishery in Mallard Lake. A total of 46 Largemouth Bass were collected during 30 minutes of electrofishing. Of the bass collected, 43% were at least 15 inches and 11% were over 18 inches in length. Body condition generally increased with length, likely due to the abundance of large shad in the lake. The largest bass collected was 4.3 lbs. | |
Developing | Walleye were stocked in Mallard Lake during 2019 and 2020, while Saugeye (Walleye x Sauger Hybrids) were stocked during 2021 and 2022. During the 2022 targeted electrofishing survey, a total of 20 Saugeye (40/hour) were collected, ranging in length from 10” to over 19”. Growth appears to be good given that young-of-year Saugeye were generally 10”-12” and Saugeye from the 2021 year class were over the legal size of 14”. Although 6 Walleye were collected during the 2021 survey, none were collected during the 2022. As hybrids, Saugeye generally demonstrate faster growth and greater tolerance of warm water in comparison to Walleye. In Mallard Lake, Walleye reached 18 inches in three growing seasons, while Saugeye reached 18 inches after just two growing seasons. | |
Good | White bass have been collected in Mallard Lake up to two lbs. during past surveys. | |
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 66-acre strip cut lake include a boat launch, floating dock, and bathrooms.
History and Status of the Sport Fishery: Thanks to upgraded equipment, electrofishing is now an effective sampling tool for this lake.
The 2021 spring nocturnal electrofishing survey was the first conducted on Mallard Lake. All fishery information prior to 2021 was based on spring trap net surveys.
The only survey conducted during 2022 was the targeted fall electrofishing survey for Walleye/Saugeye. Another multi-gear community survey is slated to occur in 2023. The targeted fall electrofishing survey suggests the Saugeye population is developing well and that anglers should now be able to catch legal-size fish (14"). Past surveys suggest Mallard Lake also supports a good bass fishery. Angler reports suggest that good crappie fishing opportunities also exist.
Additional Lake Information: Note: There is no motor HP limit, but all boats must be operated at no wake speed.
