Fish Status

BLUEGILL

Poor

The number of bluegills collected in the 2016 survey declined with very few fish of quality size were present. Although the majority of the bluegills collected in this survey fell between 3 and 5 inches, body condition for those length groups was very good. Hopefully these fish will continue to grow to sizes more appealing to the angler. The decline of bluegills from 5 inches on may be a reflection of predation on this size group by largemouth bass.

CHANNEL CATFISH

Fair

Population is supported somewhat by annual additions of 9” fish. Catfish were poorly represented in the 2016 survey but site staff report angler success. Fishing Regulation: 6 fish daily creel limit.

CRAPPIE

Poor

Although both species of crappie are present, black crappie are presently the more common of the two. Large crappies are not common, but fish in excess of ten inches have been collected during IDNR sampling. The largest individual collected in 2016 measuring just over 10 inches.

LARGEMOUTH BASS

Average

Length frequency distribution form the 2016 IDNR survey suggests that bass are somewhat stock-piled just below the legal size limit of 15 inches. Weights for these fish was substandard, a consequence of foraging competition. The absence of smaller, younger bass may be the result of predation on these fish by larger bass. This was reflected by an increase in the overall average size bass collected. At the same time, the percentage of legal-size bass fell below the long-term average which may reflect angling mortality as these fish reach and exceed the legal size limit. Fishing Regulation: 15” minimum length limit.

REDEAR SUNFISH

Good

Redear sunfish in excess of 10 inches have been collected in IDNR sampling while the average size caught in the 2016 survey measured 6.5” with fish up to 8.3" collected.

SMALLMOUTH BASS

Poor

Smallmouth bass are present in Big Lake in low density.

YELLOW BASS

Developing

The likely result of an unauthorized angler release, yellow bass have established a reproducing and recruiting population. Yellow bass collected from Big Lake during the 2016 survey averaged 7.6” and dominated the gill net collection.

Location: Silver Springs is located in Kendall County, 5 miles west of Yorkville on Fox Road. Take Fox Street west off Route 47 in Yorkville to Silver Springs State Fish and Wildlife Area.

Description: All seven of the gravel pits at this state site contain a variety of warm-water fish species, while the two largest, Beaver Lake (4.5 acres) and Big Lake, also known as Loon Lake (22.0 acres), are actively managed and will provide the most consistent action. Big Lake contains a maximum depth of 20 feet and averages 11.8 feet. A concession stand located at the park provides paddle boat rental, bait, food and drinks. A gravel boat ramp is available at Big Lake, with boats restricted to trolling motors only. A barrier-free fishing pier with access is also available at Big Lake. A one-lane concrete boat ramp on the Fox River is present as well.

History and Status of the Sport Fishery: To monitor the fish population, Big Lake is surveyed every other year. Aquatic vegetation is monitored annually and treated as required and fluridone has been utilized in early spring applications to arrest the growth of Eurasian milfoil and curleyleaf pondweed. These applications have generally provided control for multiple seasons. Aquatic habitat projects have included the introduction and establishment of selected emergent aquatic plants as well as man-made structures placed in mid-water locations.

Big Lake receives annual stockings of 8” to 10” channel catfish and catchable-size rainbow trout both spring and fall. No special mercury advisory or other contaminant-related consumption advisories pertain.

Additional Lake Information: A gravel boat ramp is available at Big Lake, with boats restricted to trolling motors only. A one-lane concrete boat ramp on the Fox River is present as well. Fishing at Big Lake is closed approximately two weeks prior to the opening of the spring and fall trout seasons.
Boaters – Electric trolling motor only
All fish species – Two pole and line fishing only
