Status of the Fishery (as of 08/02/2004)

Leek Lake is a 609-acre mesotrophic (moderately fertile) lake located in north-central Otter Tail County approximately three miles northwest of Vergas, MN. Leek Lake is part of the Otter Tail River Watershed. Two small intermittent inlets are located along the southeast shoreline and one intermittent outlet is located along the north shoreline. Both inlets and the outlet are unnavigable. The immediate watershed is composed primarily of agricultural land interspersed with mixed hardwood woodlots. The maximum depth of Leek Lake is 76 feet; however, 45% of the lake is less than 15 feet in depth. The secchi disk reading during the 2004 lake survey was 11.3 feet, which indicates excellent water clarity. Previous secchi disk readings have ranged from 6.2 to 12.0 feet. Periodic plankton/algae blooms throughout the summer months can influence secchi disk readings. Leek Lake is included in lake class 25 of the Minnesota DNR lake classification scheme. The majority of the shoreline of Leek Lake has been extensively developed. The development consists primarily of homes, cottages, and resorts. The 1984 lake resurvey report referenced 95 homes/cottages and two resorts. A DNR owned concrete public access is located off of the township road along the southwest shoreline of the lake. The shoal water substrates consist primarily of sand and rubble. The substrate of the bay areas is predominately muck. Large stands of hardstem bulrush are scattered along various shorelines of the lake. Common cattail is prevalent in several of the lakes’ bays. Emergent aquatic plants such as bulrush and cattail provide valuable fish and wildlife habitat, and are critical for maintaining good water quality. They protect shorelines and lake bottoms, and can actually absorb and break down polluting chemicals. Emergent plants provide spawning areas for fish such as northern pike, largemouth bass, and panfish. They also serve as important nursery areas for all species of fish. Because of their ecological value, emergent plants may not be removed without a DNR permit. To maintain the excellent water quality and angling that this lake has to offer, it is imperative to preserve the quality of the aquatic habitat. Leek Lake can be ecologically classified as a bass-panfish type of lake and this is reflected in the assemblage of the fish community. Northern pike, largemouth bass, black crappie, and bluegill are the dominant species in the fish community of Leek Lake. The prolificacy of these species can be attributed to the abundance of suitable spawning habitat that is available. A high-density northern pike population exists. The long-term trend has been an increase in the northern pike test-net catch rate. The catch rate also exceeded the upper limit of the normal range for lake class 25. Age data indicate that pike natural reproduction is consistently good. Northern pike ranged in length from 11.0 to 28.2 inches with an average length and weight of 17.8 inches and 1.2 pounds. Pike exhibit extremely slow growth with an average length of 18.0 inches at five years of age. The slow growth rates for pike may be attributed to the high-density population and to the low abundance of yellow perch, a preferred forage fish. Data collected from a spring electrofishing assessment indicated that Leek Lake has a balanced largemouth bass population. Bass ranged in length from 6.5 to 18.3 inches with an average length and weight of 10.7 inches and 0.9 pounds. Bass exhibit good growth rates with an average length of 12.2 inches at age-IV. Catch data from a spring trapnetting assessment indicated that black crappie are abundant in Leek Lake. Crappies ranged in length from 5.6 to 12.4 inches with an average length and weight of 9.8 inches and 0.6 pounds. Seventy-seven percent of the crappies were at least 9.0 inches in length. A strong 1998 year class should provide good crappie angling for several years. Crappies attain an average length of 9.9 inches at five years of age. The bluegill test-net catch rate exceeded the upper limit of the normal range for class 25 lakes. The general trend has been an increase in bluegill abundance. Twenty-three percent of the bluegill sample was at least 7.0 inches in length. Age data indicate that bluegill reproduction is consistently good. Bluegills attain an average length of 6.8 inches at seven years of age. The walleye test-net catch rate was within the normal range for lake class 25. Walleye abundance has historically been low in Leek Lake. Walleye ranged in length from 12.0 to 22.1 inches with an average length and weight of 16.7 and 1.6 pounds. Walleye fry were stocked in Leek Lake over the recent series of surveys, however; age and catch data indicated that the extent of contribution to the walleye population was negligible. The DNR initiated a biennial walleye fingerling stocking sequence in 2000 which will be evaluated over the future series of lake surveys. This stocking plan may increase walleye angling opportunities for anglers of Leek Lake. Anglers can maintain the quality of fishing in Leek Lake by practicing selective harvest. Selective harvest encourages the release of medium to large-size fish while allowing the harvest of the more abundant smaller fish for table fare. Releasing the medium to large fish will ensure that the lake will have enough spawning age fish on an annual basis and will provide anglers with more opportunities to catch large fish in the future.
