Fishing Outlook
Largemouth Bass
Average
Seventeen Largemouth Bass were caught in 25 minutes of shocking (41 fish per hour) during the 2020 fish survey. This is a slightly lower than the management goal of 60 fish per hour. The bass in the sample ranged in length from 3.9 to 16.9 inches with an average length of 10.2 inches. Mays Lake had a good proportion of large bass with five of the 17 bass measuring longer than 12 inches. Two fish over 16 inches were present in the sample. Larger fish may be present in the privately-owned portion of the lake, as the habitat and depth are more desirable.
Bluegill
Good
Bluegill catch rate was 146 fish per hour. This is very close to the management goal of 120 fish per hour. This is a good catch rate in that the Bluegills aren’t over-populated or stunted. Bluegills ranged in length from 2.4 to 7.7 inches, with an average size of 6.0 inches. This is the first survey since 2006 that contained Bluegill over seven inches. Fifty-one percent of the Bluegills in the sample measured longer than six inches. Bluegills in Trinity Lake were in good body condition.
Channel Catfish
Improving
Channel Catfish stocking occurred in 2012, 2013 and 2017 so all of the Channel Catfish should be longer than the 12-inch minimum length limit.

Description
Trinity Lake is a 6.1-acre dug pond with a maximum depth of 18 feet and an average depth of 8 feet. Trinity Lake is one of 30 lakes and ponds owned and maintained for sport fishing by the Forest Preserve District of DuPage County (FPDDC). The District owns about 3 acres on the north end of Trinity Lake. There is a small cleared shoreline fishing access area directly behind the estate.Fishery History
These waters have been under management by the FPDDC Fishery Ecologist to provide quality sport fishing opportunities. In 1984, the FPDDC entered into a Cooperative Management Agreement with the Illinois Department of Natural Resources to facilitate management activities. Largemouth Bass and Channel Catfish are occasionally stocked to supplement the population. Current regulations are designed to increase numbers of preferred size bass as well as increase the size of Bluegill (more large bass to feed on small Bluegill). A 25-minute electrofishing survey was conducted on June 4, 2020. A 2016 survey showed a more abundant bass population than the previous survey, with a good proportion of large fish (half the sample over 15 inches). The 2020 survey numbers were slightly lower. Bluegill abundance in 2020 was similar to the sample in 2016 with a good number of fish over 6 inches. Only the FPDDC county portion of the lake was sampled.
