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.
