Girl Lake is a 406 acre lake located near Longville, Minnesota. Girl Lake has 9.36 miles of shoreline, and a maximum depth of 81 feet. Sixty seven percent of the lake is 15 feet deep or less. The Minnesota Department of Natural Resources has classified Minnesota's lakes into 43 different lake classes based on physical, chemical, and other characteristics. Girl Lake is in Lake Class 25. Lakes in this class are medium sized, moderately deep, irregularly shaped, and clear. A city owned public access is located on the east side of the lake in Longville.
Girl Lake offers good opportunities for anglers seeking a variety of species. The average length of northern pike sampled in the 2012 survey was 17 inches and the lengths ranged from 10 to 33 inches. A 24 to 36 inch protected slot regulation on northern pike was implemented in 2003 with the objective of increasing the percentage of northern pike 24 inches or longer in the Woman Lake chain (Child, Girl, and Woman lakes). Pike catch rates were the highest observed but lengths in Girl Lake were still below the management goal. Largemouth bass are present in Girl Lake with sizes in the 2012 sample ranging from 7 to 16 inches. Black crappies numbers are average for similar area lakes with fish greater than 10 inches in length present. Black crappie average length was 7 inches and the lengths ranged from 5 to 12 inches. A low-abundance but high size quality muskellunge population is present in the Woman Lake chain. Bluegill sampled in summer netting had an average length of 6 inches with lengths ranging from 3 to 9 inches. Yellow perch numbers have increased in Girl Lake with fish averaging just over 7 inches in length. Walleye abundance was low but lengths ranged from 13 to 26 inches. Other species sampled were black bullhead, bowfin (dogfish), brown bullhead, burbot, pumpkinseed sunfish, rock bass, tullibee (cisco), yellow bullhead, and white sucker.
People can have significant impacts on lakes and the fish populations they support. Harvest, lakeshore development, removal of shoreline vegetation, and introductions of invasive species can all adversely affect fish populations. Currently the aquatic invasive species (AIS) that have been identified in Girl Lake are the rusty crayfish, purple loosestrife and curly leaf pondweed. AIS are moved from infested to non-infested waters by anglers, boaters, and lake shore owners and can adversely impact lakes and fish populations. To avoid spreading AIS, lake users are required to remove all aquatic plants or animals from their watercraft and drain all water from their boat before leaving the access. If you suspect an infestation of an invasive species in this lake, save a specimen and report it to a local natural resource office. Additional information on all of these topics can be found on the DNR website (www.dnr.state.mn.us) or by contacting the Walker Area Fisheries office.

Recreational activities such as recreational boating, angling, waterfowl hunting, and diving may spread aquatic invasive species. Some aquatic invasive species can attach to boats, while others can become tangled on propellers, anchor lines, or boat trailers. Many species can survive in bilge water, ballast tanks, and motors or may hide in dirt or sand that clings to nets, buckets, anchors, and waders. Fortunately, completing simple steps can prevent the transport of aquatic invasive species.
