Fish Status

BLACK CRAPPIE

Good

Black Crappie collected ranged from 4” to 9.25” long. Anglers often keep crappie at least 9” long, so there is a harvestable fishery present. Like bluegill, added predation should help “grow” the crappie population in the future.

BLUEGILL

Fair

In 2015, Bluegill captured ranged from 1” to 6.8”. 30% were longer than 6”, but none were over 7” long. The expanding bass population and increasing muskie predation should help boost the size of panfish in Diamond Lake in the coming years.

CHANNEL CATFISH

Good

Annual stockings of 8” to 10” channel catfish maintains their presence, and although we collected several fish up to 23” long, weighing up to 5 lbs., larger fish are present in the lake and provide anglers with both sport and table fare. Site Regulation: 6 fish daily creel limit.

LARGEMOUTH BASS

Good

In 2015, bass collected measured 2” to 20.5” and weighed up to 5.2 lbs. 72% were over 12” long, 67% were over 14” long, and 50% were over 15” long. This size structure allows for quality angling opportunities and should create better pan fishing in the future. Site Regulation: 15” minimum length limit ; 3 fish daily creel limit.

MUSKELLUNGE

Developing

Muskie have been stocked in this lake beginning in 2013. Site Regulation: 36" minimum length limit, 1 fish daily creel limit.

Location: Diamond Lake is located in northeastern Lake County, within the Village of Mundelein.

Description: A glacial origin lake, the majority of Diamond Lake bottom is owned by the Mundelein Park District, which it acquired in the late 1960s. Water exits the lake in the southeastern portion of the lake via a spillway that flows underground until it connects to Indian Creek. Diamond Lake is 153 acres; shoreline length 5.9 miles; watershed 686 acres (5 to 1); maximum depth 23 feet; average depth 7.6 feet. There are several ramps around the lake but only one is open to the public (fee required). It is a single, concrete boat ramp on the southeast end of the lake near the beach. No fishing boat rentals are available; a private bait shop is located 1 mile south of the ramp. No fish cleaning facilities are available.

History and Status of the Sport Fishery: Occasional fish surveys are conducted to evaluate stocking success and changes in the fishery. Herbicides are occasionally applied in high-use areas to maintain recreational boat access because the shoreline is generally shallow and Eurasian watermilfoil is present in the system.

Diamond Lake receives annual stockings of 8” to 10” Channel Catfish, 10” Northern Pike, and occasional stockings of 12” muskie (beginning in 2013). We collected 13 species in this mid-sized glacial lake. Additional fish species include: northern pike, muskie, common carp, pumpkinseed sunfish, golden shiners, yellow perch, green sunfish, yellow bass and gizzard shad.

Additional Lake Information: All fish species, two pole and line fishing only. The one public boat ramp on the southeast end of the lake near the beach requires a fee for use.
