Fish Status

BLUEGILL

Average

Bluegills were the second most common fish collected in 2017, accounting for 32.2% of the total fish collection. Bluegills continued to dominate the trap net catch, accounting for more than one-half of the total number of fish collected by that gear type. While the 2015 survey indicated very good numbers of quality-size bluegills, the 2017 survey indicated the opposite as the number of 6” plus bluegills declined to its lowest point in many years; the average size bluegill collected in the 2017 survey measured 4.7”. It would appear that combined mortality has impacted the top end of the population. If the smaller bluegills recruit favorably, this population should begin to recover in the coming years.

CHANNEL CATFISH

Average

A difficult species to sample in strip-mine lakes, channel catfish were collected in fairly low number in 2017. Reproduction and recruitment appear sporadic. Catfish collected in 2017 averaged 19.8” with the largest fish exceeding 25”. Channel catfish are stocked on a rotational basis with other Mazonia lake.

CRAPPIE

Good

White and black crappie were collected in fair number in 2017 with black crappie the more numerous of the two species. The combined crappie sample would indicate a fair population present with good angling opportunity. Crappie that were at least 10 inches in length comprised 16% of the adult population, and several fish were collected that exceeded one pound.

LARGEMOUTH BASS

Improving

Electrofishing catch rates increased to their highest point in 8 years as the total number of stock size and larger bass (8”-plus) increased. The average size bass collected in 2017 measured 12.4”. Although the total number of largemouth bass collected increased, there was minimal change to the overall population. Legal-size bass declined slightly, although good numbers of legal-size bass are present; 4% of bass that were of quality size were at least 18 inches in length.

Location: Bullhead Lake (Lake #7) is located within the Mazonia State Fish and Wildlife Area Main Unit, 3 miles southwest of Braidwood in Grundy County on Illinois Route 53 and Huston Road.

Description: Bullhead Lake is one of the largest impoundments in the Main Unit at 32.9 surface acres. Shoreline access is limited by extensive stands of tall reed grass. The lake has a one-lane concrete boat ramp with adjacent parking. Bullhead Lake is closed to fishing during upland game and waterfowl season. Following the completion of the hunting seasons, it reopens for ice fishing dependent upon ice conditions.

History and Status of the Sport Fishery: No special mercury advisory or other contaminant-related consumption advisories pertain. Bullhead Lake is surveyed on an alternate year basis. Fish stocking has been limited to mainly channel catfish. A variety of other species that can be caught in Bullhead Lake include common carp, freshwater drum, bullheads, green sunfish and several gar species.

Additional Lake Information: Trolling motor only. Two pole and line fishing only.
