Townline Lake has an area of 510 acres and is located near Longville, MN. Townline Lake has 6.7 miles of shoreline and a maximum depth of 11 feet. The Minnesota Department of Natural Resources (MNDNR) has classified Minnesota's lakes into 43 different classes based on physical, chemical and other characteristics. Townline Lake is in Lake Class 39; lakes in this class are generally shallow, regularly shaped lakes. This lake is primarily managed for northern pike and bluegill and secondarily for largemouth bass and black crappie. Fish population surveys have been conducted by the MNDNR in 1974, 1985, 1990, 1995 and 1998. The current survey was done in 2001. During the winter of 1995-96 a winterkill was reported on Townline Lake. DNR biologist sampled the lake in 1996 with gill nets and electroshocking gears and collected several northern pike and a golden shiner. Partial winterkills were also reported in 1962 and 1971. In an attempt to reestablish the fish population in Townline Lake the DNR stocked walleye fry in 1996 and adult largemouth bass, bluegill and black crappie in 1997. Additionally, Leach Lake Reservation biologists stocked adult yellow perch in 1997. Northern pike were very abundant in Townline Lake. Northern pike sampled by the DNR ranged between 10.4 and 35.6 inches; the average length was 20.3 inches. The northern pike sampled in 2001 were very plump. Bluegills ranging in size from 2.8 to 8.5 inches were sampled by the DNR during the 2001 survey. Similar to the northern pike catch rates, bluegill catch rates in Townline Lake were the highest on record in 2001. The modal length group of bluegills sampled in DNR trap nets was 3.0-3.5 inches. Though most bluegill sampled were small, they were very plump indicating that the food supply in Townline Lake is more than adequate. Since the winterkill in 1995-96 the largemouth bass population has slowly been rebuilding. In 1998 no largemouth bass were collected and in 2001 two fish were collected. Electrofishing, which is a more effective tool for sampling bass, indicated a fairly abundant population in 1999. No electrofishing was conducted in 2001. The yellow perch population has been stable since surveys were first conducted in 1974. Yellow perch ranged in size from 4.4 to 15.0 inches. Similar to largemouth bass, very few black crappie were sampled in the 2001 survey. In 2001 four black crappie were collected ranging in size from 6.2 to 12.2 inches. Rock bass were collected for the first time in Townline Lake during the 2001 survey; one fish in the DNR trap nets. The pumpkinseed population shows the most noticeable change since surveys were started in 1974. Gill net catch rates have steadily declined from 1985 to 2001. Anglers can help maintain or improve the quality of fishing by practicing selective harvest. Selective harvest allows for the harvest of smaller fish for table fare, but encourages release of medium- to large-sized fish. Releasing these fish can help maintain balance in the fish community in Long Lake and provide anglers the opportunity to catch more and larger fish in the future. Shoreline areas on the land and into the shallow water provide essential habitat for fish and wildlife that live in or near Minnesota's lakes. Overdeveloped shorelines can't support the fish, wildlife, and clean water that are associated with natural undeveloped lakes. The combined effects of all lakeshore owners "fixing up" their property can destroy a lake's valuable natural shorelines. Shoreline habitat consists of aquatic plants, woody plants and natural lake bottom soils. Plants in the water and at the water's edge provide habitat, prevent erosion and absorb excess nutrients. Shrubs, trees, and woody debris such as fallen trees or limbs provide good habitat both above and below the water and should be left in place. Natural lake bottom materials like silt or gravel are more ecologically productive than pure sand trucked in for a swimming beach. A tidy lawn and a sandy beach make great spots for sunbathing and swimming but do little to provide habitat for fish and wildlife. By leaving a buffer strip of natural vegetation along the shoreline, property owners can reduce erosion, help maintain water quality, and provide habitat and travel corridors for wildlife. Only if more lakeshore owners manage their shoreline in a natural condition can fish and wildlife populations on Minnesota lakes remain healthy and abundant. More specific information on protecting or restoring shorelines and watersheds is available through the local DNR Fisheries office.
