Fish Status



As in previous years, bluegill catch rate was low and no fish longer than six inches were captured. Other species contribute to the panfish fishery at Mallard to make up for a lack of bluegill. Pumpkinseed, black crappie, and yellow perch are all present in the lake and large individuals of those species are present.



Channel catfish are stocked sporadically. Lack of channel catfish catch in our surveys suggests high angler harvest or low sampling gear efficiency.



Both black and white crappie are present in Mallard Lake. Black crappie are more abundant and numbers have been stable over the years for this species.


Very Good

The largemouth bass population has improved since the 2012 fish survey. Catch rates and numbers of adult fish are higher than they’ve been in the last two surveys. Bass were caught at a rate that is higher than the management goal, and the population shows no signs of stunting. Bass ranged in length from 4.3 to 17.8 inches, with the average bass measuring 11.3 inches. Forty-nine percent of the bass were in the 10-14 inch length group while 18% of the bass measured longer than 14 inches.



Catch rates for spring net surveys have been highly variable since annual monitoring began. The 2018 survey only yielded one 24 inch muskie despite setting seven nets over two nights. We have caught as many as 26 fish with the same effort. The largest muskie sampled was 45.7 inches; anglers have reported 48 inch fish. Muskie are stocked every other year at a rate of one fish per acre (90 fish).



Northern pike were historically stocked in this lake, and fish over the 24 inch legal limit have been caught in two out of five of the last spring trap-net surveys.



Some very nice walleye have shown up in recent surveys and 2018 was no exception. Twenty six walleye were caught in the 2018 spring survey for the highest catch rate since monitoring began in 2011. The walleye ranged in length from 9.6 to 23.7 inches with the largest weighing 5.2 pounds – tying the largest captured since 2011. Twenty-seven percent of the catch was longer than the 16 inch legal length limit.



Yellow perch over the nine inch minimum length limit were caught in spring trap-nets.

Location: Mallard Lake is in Hanover Park, in Dupage County. Parking lot is off of Schick Road west of Gary Avenue.

Description: Mallard Lake is an 85 acre man-made lake with a maximum depth of 25 feet owned by the Forest Preserve District of Dupage County. The lake is managed under a cooperative management agreement with the Illinois Department of Natural Resources. There is an island with bridges connecting two sides of the lake. There are two handicapped accessible fishing piers and several access paths. Carry-in boats under 20 feet are allowed (no boat ramp is available). No gasoline powered motors allowed. A smaller 9 acre pond (Cloverdale Pond) is also accessible at Mallard Lake Forest Preserve.

History and Status of the Sport Fishery: Mallard offers a variety of fish species, so don't be surprised if your bait comes under attack from a hungry largemouth bass, walleye, northern pike or muskie! Although this lake does receive fairly heavy fishing pressure, there are some truly memorable fish to be caught. Forage species include: yellow perch, gizzard shad, bluegill, green sunfish, golden shiner, and bluntnose minnows.

This fish community is surveyed every four years while trap-net surveys targeting muskie take place each spring. Three brush piles and a pallet style fish crib were placed in the lake in 2016. *New regulations for FPDDC lakes and ponds take effect April 1st, 2017.

Additional Lake Information: No gasoline powered motors allowed.
