Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
North Twin Lake is a small, relatively clear lake in central Itasca County near Marble, Minnesota. The lakeshore has moderate levels of municipal and residential development. North Twin supports a relatively diverse aquatic plant community. Unfortunately, three exotic, invasive plants are present. Exotic aquatic plants are detrimental to the native aquatic plant community and often interfere with recreation. Eurasian water milfoil is present but appears to be limited in distribution at this time. Purple loosestrife and flowering rush are more widespread around the lake and appear to have displaced some other native, emergent plant species. Anglers should take care to remove all plant materials from boats, motors, trailers, and other gear. Despite the invasion by exotic plants and moderate levels of shoreline disturbance, North Twin Lake supports adequate fish habitat for a variety of species. The lake is connected to the Swan River via the outlet to South Twin Lake. This connectivity has resulted in a diverse fish community that offers anglers good opportunity for a variety of fish species. The lake is managed for northern pike, largemouth bass, and panfish. A population assessment was conducted in August of 2008 to assess the status and characteristics of the fish community. Bluegill were the most common fish in both the trap nets and the gill nets. The trap net catch rate was within the expect range in comparison to similar lakes and was similar to previous assessments conducted on North Twin. North Twin Lake has a history of producing relatively small bluegill and small average size may limit the popularity of the fishery. In 2008, the size structure was poor, as most individuals did not exceed 7 inches. Lakes with characteristics similar to North Twin rarely produce fast growing bluegill and growth of bluegill from North Twin was average, with individuals typically obtaining 6 inches in seven years. The 2001 year-class appeared relatively strong and may provide some quality fishing as individuals from that year-class averaged nearly seven inches at the time of capture. Northern pike were the second most common fish in the gill net. The gill net catch rate was within the expected range for this type of lake. Size structure was relatively poor as most individuals were did not exceed 21 inches. A few large individuals remain present, however, as one fish exceeding 36 inches was sampled. Growth was near the statewide average and individuals typically exceeded 21 inches in 5 years. Only 15% of the sampled individuals exceeded age 5, suggesting high…
