Giles Lake is located three miles southwest of Cohasset, Minnesota. The lake is a small bass/panfish lake with moderate aquatic vegetation. There is a county owned, gravel boat access on the northeast side of the lake. Black crappie are difficult to sample during the summer because they are often dispersed and suspended. The population seemed to be in good shape in 1999 and when compared to similar lakes was near the top 25 percent. Fish ranged from 4.5 to 9.8 inches with an average length near 6.5 inches. Black crappie from two to seven years old were aged with the 1994 year class representing more than 50% of the sample. Growth was slower than the statewide averages for all ages. Slower growth rates generally occur in higher density populations. Bluegill numbers have been average in all assessments. In 1999, the number of fish caught in trap nets were higher than in previous samples. These fish ranged from 3.3 to 7.7 inches with an average length of 6.1 inches. Bluegill were not aged in 1999 but based on the length frequency distribution, multiple year classes were present. Northern pike numbers were average when compared to lakes similar to Giles. Fish ranged from 19.1 to 33.5 inches and had an average length of 23.7 inches. Five year classes were identified by age analysis ranging from two to eight years old. The 1996 and 1997 year classes represented nearly 85 percent of the sample. Growth was good and exceeded statewide averages for all ages. The yellow perch population has experienced extreme highs and lows in the last 20 years. From 1978 to 1989, net catch rates went from 195.0 fish/net to zero. A variety of things took place during that period but one notable change was that northern pike numbers increased substantially. In 1999, yellow perch numbers rebounded to 39.0 fish/net which puts the population back to a healthy level for lakes like Giles. These fish ranged from 5.4 to 10.2 inches and had an average length of 6.4 inches. Other species sampled in 1999 included bowfin, largemouth bass, pumpkinseed sunfish, and yellow bullhead. Since electrofishing was not used to sample largemouth bass in 1999 it is difficult to characterize the population. To promote and maintain healthy fish populations, water quality must be protected. Fish habitat is directly affected by water quality. Nutrients, sediments and other waste can drastically alter the chemical and physical characteristics of a lake. People often associate water quality problems in a lake with agricultural, forestry or industrial practices within the watershed. Although these can be areas of concern, lakeshore property owners also contribute to water quality problems. Some examples include putting in sand beaches, removing shoreline trees and vegetation, fertilizing lawns, and mowing their lawns down to the lakeshore. Continued good land use practices by everyone should insure that this fishery can be enjoyed by future generations.
