Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Status of the Fishery (as of 06/06/2011)

Clear is a 415-acre located three miles west of the city of Jackson in Jackson County. The lake has a maximum depth of 9.0 feet and is a class 43 lake. Clear is managed primarily for walleye while yellow perch and northern pike are managed secondarily. The lake is presently stocked with walleye fry 3 of 4 years at 500 fish per littoral acre in an effort to boost walleye abundance and numbers of year classes. Because of Clear Lake's popularity, the fish population is assessed every other year.

Clear Lake has a great walleye population when compared to other lakes similar to Clear Lake. The gill net catch more than doubled from the 2009 assessment. Lengths of walleye caught in our gill nets ranged from 13.5 to 19.3 inches and averaged 15.4 inches. The majority of walleye sampled were age 2 and more than likely resulted from a fry stocking in 2009. This points out that the current walleye fry stocking plan seems to be working well, and the population is dominated with good eater sized walleyes.

In addition to a respectable walleye population, the yellow perch numbers are impressive. Although Clear Lake has had catch rates historically higher, the yellow perch population was well above the average when compared to other lakes. The catch rate in 2011 was an impressive 47.7 fish per gill net compared to 25.0 fish per gill net like other similar lakes like Clear. Lengths of yellow perch caught in our gill nets ranged from 7.1 to 12.7 inches and averaged 10.6 inches. Most of the yellow perch were in the 10-12 inch range which could be a great size for the frying pan.

Northern pike are managed as a secondary species in Clear Lake and were stocked with fingerlings in 2004, 2005, 2007, and 2010. In addition to the fingerlings in 2010, 14 adult northern pike were stocked. Only one 35.8 inch northern pike was sampled during the 2011. The northern pike gill net catch was 0.3 in 2011 compared to 0.0 in 2009, 0.3 in 2007, 2.3 in 2005, and 0.1 in 2003. The northern pike in Clear Lake have not had success which may be due in part to lack of spawning habitat.

Black crappies are present in Clear Lake. Crappie numbers were "middle-of-the-road" when compared to lakes similar to Clear Lake. Lengths of black crappie caught in our trap nets ranged from 5.5 to 12.1 inches with an impressive average of 9.3 inches. The opportunity is there to catch some nice slabs.

Bluegills are also present in Clear Lake. Bluegill numbers are low, but over the last three assessments have been trending upward. This may be due in part to sporadic spots of submergent vegetation showing up the past couple years providing some habitat. Lengths of bluegills caught in our trap nets ranged from 5.1 to 9.3 inches and averaged 6.8.

Black bullhead numbers are also low in Clear Lake but the lengths are impressive. Lengths of black bullhead ranged from 10.3 to 14.1 inches and averaged 12.6 inches.

Other fish sampled during the assessment included largemouth bass, smallmouth bass, pumpkinseed, green sunfish, bigmouth buffalo, common carp, freshwater drum, channel catfish, brown bullhead, yellow bullhead, and fathead minnow.

To maintain a healthy fishery in Clear Lake, we need to promote Best Management Practices (BMPs) within the watershed to help reduce nutrients entering the lake. High nutrients and sediments in a lake can cause algae blooms and reduce water clarity.
