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.
Townline Lake is located about five miles southwest of the City of Aitkin along the border between Aitkin and Crow Wing counties. Most of the land surrounding the lake is rolling hills covered by mixed forests and wetlands. Residential development is light and concentrated on the north half of the lake with a county road along the west shore. There is no designated public access on the lake. Anglers who obtain legal access will have opportunities to catch many popular species commonly found in bass-panfish lakes. Largemouth bass were abundant in survey nets with a variety of sizes up to about 16 inches sampled. Reproduction of bass appears consistent with each of the last seven year-classes represented in the sample. Northern pike were captured in slightly lower numbers than the previous survey, but still fairly abundant compared to similar lakes. Size of pike in gill nets averaged 19 inches with 18% greater than 24 inches and fish as large as 33 inches sampled. Panfish anglers should have ample opportunities to catch decent fish. Abundance of bluegill captured in survey trap nets remained within the normal range for similar lakes. Size ranged from 3.4 to 8.7 inches with an average of 6.1 inches and 24% greater than 7 inches. Age analysis revealed consistent reproduction, but slow growth compared to statewide averages. In contrast, age analysis of black crappie showed sporadic recruitment and fast growth. Abundance has also varied significantly between surveys suggesting that crappie fishing may be cyclic around occasional good year-classes. Pumpkinseed and hybrid sunfish also offer panfish anglers opportunities to catch sunfish larger than 8 inches.
