Species

Rank

Fish Status

BLUEGILL

Poor

Surveys have shown the bulk of the bluegill population being from 3" - 5". The indices were slightly better in 2023 with 0.2% of the population sampled being over 8 inches and having an average body condition value of 93.

CHANNEL CATFISH

Excellent

An excellent population of catchable-sized channel catfish from 10 - 22 inches is found at North Spring Lake. Best fishing for these fish is found along the Northwest levee and on the outside of the aquatic vegetation beds. Best fishing for channel catfish is at night from May through July.

CRAPPIE

Good

The 2023 indices showed 7 percent of the fish were over 15.7 inches and the body condition of 90. In 2018 a new harvest regulation started for crappie. This regulation is a harvest limit of 25 fish per day with only 10 fish over 10 inches allowed. This regulation will allow harvest pressure on the large percentage of crappie that are under 9 inches in length.

LARGEMOUTH BASS

Good

The 2023 surveys show the largemouth bass population was meeting or just under all desired population indices, with 45.4% being over 12 inches, 17.8% of the population being above 15 inches and 3.3% above 20 inches. This could be attributed to highly successful aquatic vegetation treatments in recent years along with the protected slot limit. The body condition was good with an average value of 89. In 2018 a new harvest regulation went into effect for largemouth bass. The regulation is a protected slot from 12 to 18 inches with 3 fish per day harvest. This is an attempt to restructure to bass population to a larger percent of fish over 16 inches. Growth and condition have been tremendously impacted by the dense growth of Eurasian milfoil in the past. The management of North Spring Lake was geared toward opening forage “edge” in these solid growth milfoil beds and shifting vegetation types to native species.

MUSKELLUNGE

Excellent

The 2023 spring musky survey yielded 39 fish, for a total of 0.2 fish per net-night. 89.7% of fish captured were greater or equal to 30”, with 2.6% of those being greater than 38”. The largest fish was a 40” female. Female to male ratio was 30% female: 70% male.

REDEAR SUNFISH

Poor

Surveys have shown the bulk of the redear population being from 5" - 7" and with 61.5% being over 6 inches.

Location: North Spring Lake is a 578 acre body of water located 6 miles north and west of Manito, Illinois, adjacent to the Illinois River.

Description: North Spring Lake is an elongated backwater lateral marsh of the Illinois River. It was separated by a high levee from the Illinois River in 1916. The North Lake was separated from the South Lake in 1978 by a stop log structure and a spillway for discharge water. North Spring Lake receives 52 acre feet of recharge daily from springs and seeps. Spring Lake currently has a 25 horsepower limit for outboard motors. The main access is via the Spring Lake blacktop road. A single lane boat ramp is located along the causeway which crosses Spring Lake. An additional gravel ramp is located adjacent to the Sky Ranch blacktop road bridge crossing of North Spring Lake. North Spring Lake is a shallow, very fertile backwater. It has a 75% coverage of aquatic vegetation after April and until November of each year. The lake is closed to boat fishing one week prior to regular waterfowl season, and until the end of waterfowl season each year.

Always a shallow body of water, Spring Lake has an average depth of 2.9 feet. Of the 578 acres of water, at least 75% is covered with 17 different species of aquatic vegetation by late May of each year. The majority of this coverage now consists of Eurasian milfoil, lily and lotus. The tremendous spring recharge from the bed of the lake amounts to 52 acre feet a day, creating very cold water temperatures under the insulating layer of vegetation for the majority of the summer months. This is a unique situation and only occurs in Spring Lake within the State of Illinois.

History and Status of the Sport Fishery: North spring Lake was rehabilitated in the 1980s to remove an undesirable carp-gizzard shad fish population. As a result of the rehabilitation, an excellent fish population resulted. Water clarity improved and aquatic weeds flourished. Good fishing for largemouth bass, crappie, sunfish and catfish soon resulted. As part of an effort to develop a brood source for muskie, Spring Lake has been stocked with that species for 25 years. Muskie are trap netted at the lake and spawned at the Jake Wolf Fish Hatchery in March of each year. A total of over half a million eggs are produced for state-wide muskie needs each year. The muskie population is being continuously monitored using electronic tags. This marking program has been ongoing since 1999. Because of its shallow water and clarity, North Spring Lake has a tremendous coverage of aquatic vegetation. As part of an effort to reduce coverage of Eurasian milfoil (an exotic invasive plant), North Spring Lake is treated with DMA4-2, 4D each year.

Additional Lake Information: North Spring Lake has three useable boat ramps and is accessible by the Manito Blacktop, 12 miles south of Pekin. No fuel or services are available, however, camping and food is. There is a 25 horsepower limit at Spring Lake.

Tournaments: All bass tournaments must register online using the new Tournament Permit System at least 30 days before the event.

New Site Regulation Effective April 2018:
Largemouth bass: protected slot length from 12 to 18 inches, with the harvest of 3 fish either over or under this protected slot.

Crappie: harvest limit of 25 fish per day with only 10 fish over 10 inches allowed.
