Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2012 Walleye fry 1,500,000 16.5
2010 Walleye fry 1,500,000 15.0
2008 Walleye fry 1,500,000 15.0
2006 Walleye fry 1,500,000 15.0
2004 Walleye fry 1,500,000 15.0

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.

Fish Consumption Guidelines

These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Status of the Fishery (as of 07/18/2005)

Clearwater Lake is a 3,158-acre lake located two miles north of the city of Annandale in Wright and Stearns Counties. The lake is made up of two basins (east and west). The lakeshore is highly developed, with 80% of the shoreline being taken up by homes or cabins. There are two public accesses located on the west basin. In 2005, a lake survey was conducted in order to assess the fish populations in Clearwater Lake. With its vast emergent vegetation and complicated submerged structure Clearwater will provide a delightful challenge to anglers.

Largemouth Bass Clearwater Lake has a reputation as one of Minnesota's best bass fisheries. Approximately 10 tournaments are held each year. We sampled largemouth bass with electrofishing and found that the population is large and consists of fish from five to 20 inches or more. The catch rate of largemouth bass was 73.3 fish/hour, which exceeds the typical catch rate for lakes in the Montrose area.

Northern Pike The northern pike gill net catch rate was near the upper end of expected values for similar lakes. Mean length and weight of northern pike sampled was 21.9 inches and 2.4 pounds. During a creel survey in 2005 mean length and weight of northern pike harvested by anglers was 23.5 inches and 3.0 pounds. This indicates a selective harvest on the part of the anglers. Anglers are encouraged to harvest small fish in order to improve the size structure.

Walleye The walleye catch rate in 2005 (5.4 fish/net) was lower than observed in 1997 (7.2 fish/net), but was within the range of expected values for similar lakes. Mean length and weight of walleye sampled was 16.4 inches and 1.6 pounds, slightly larger than the walleye that anglers harvest, 15.2 inches and 1.3 pounds. The fishery is characterized by young fish which are the result of successful fry stocking.

Bluegill The bluegill catch rate in 2005 (18.1 fish/net) was similar to 1997 (16.7 fish/net) and within the range of expected values for similar lakes. Bluegill sampled ranged in length from 2.8 inches to 7.9 inches. Sunfish were the most common species taken by anglers during the 2005 creel. The average size harvested was 7.2 inches, considered good by area standards.

Black crappie are rarely taken with trap nets at Clearwater Lake. However, it was estimated that more than 8,600 black crappie were harvested by anglers during the summer 2005 creel survey. Harvested fish ranged in length from 6.0 to 16.0 inches with a mean length of 9.6 inches.

Other species sampled during the survey included: black, brown and yellow bullheads, bowfin, common carp, golden shiner, hybrid and pumpkinseed sunfish, rock bass, tullibee, and white sucker.
