Fish Status



Bluegill were abundant and catch rate was 142 fish per hour. Bluegill ranged in length from 2.4 to 6.8 inches, with an average size of 5.0 inches.


Very Good

Common carp dislodge vegetation and cloud the water with their feeding behavior of “rooting” through the substrate. Since this lake receives floodwater from nearby Blackberry Creek, there is no way to eradicate carp. Unlimited harvest is encouraged for this detrimental species to keep their numbers down.



This lake is scheduled to receive 1,300 four inch channel catfish every other year from the IDNR’s catfish stocking program. Since catfish stocking began in 2012, there should be plenty of large Channel Cats swimming in Lake Gregory.


Very Good

Population indices for Largemouth Bass were similar to 2015 with slightly lower numbers of fish over 15 inches. The current catch-rate was 114 fish per hour. Fifty-six percent of bass in the sample were over 12 inches long while 9% were longer than 15 inches. Multiple year classes of fish indicate successful spawns in recent years. A diverse and abundant forage base ensures bass are well fed in this lake!

Location: Lake Gregory is located at the Blackberry Farm, 100 S. Barnes Rd. in Aurora.

Description: Lake Gregory is a 7.2-acre dug recreational lake located adjacent to Blackberry Creek in the Fox Valley Park District’s (FVPD) Blackberry Farm Historic Park. The lake has a maximum depth of 8.4 ft. and an average depth of 5.4 ft. Flow through from adjacent storm sewers help keep this shallow lake from serious winter kill. The shoreline is mowed in several areas to allow access for shore fishing. Many activities are available at the farm including train and pony rides, paddleboats and live entertainment. If you are looking for a quiet destination with few distractions, this may not be to the place to go! There is a five dollar fee to enter the park.

History and Status of the Sport Fishery: The FVPD has entered into a cooperative management agreement with the Illinois Department of Natural Resources to facilitate fisheries management activities. A 30-minute electrofishing survey took place on September 17th, 2020 as a follow up to a 2015 survey. Prior to that the lake was surveyed in 2007. Channel Catfish have been stocked five times since 2012 (1300 4-5-inch fish per stocking).
A abundant Largemouth Bass and Bluegill population should entertain any angler. Bass were more slightly less abundant than in the 2007 survey. Bluegill abundance was the same as 2015, but the fall sample time most likely under-estimated the size of both Species. The stocking of small channel catfish should improve this fishery in years to come as well!
