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.
Barnum Lake has an area of 134 acres and a maximum depth of 30 feet. About two-thirds of Barnum Lake is 15 feet or less in depth. Barnum Lake is located about nine miles east and three miles north of Hackensack, MN. The Minnesota Department of Natural Resources (MN DNR) has classified Minnesota's lakes into 43 different lake classes based on physical, chemical and other characteristics. Barnum Lake is in lake class 32. Lakes in this class generally have hard water, a large percentage of area 15 feet or less in depth and an irregular shoreline. Barnum Lake has no designated public access. Though most of the Barnum Lake shoreline is in private ownership, some of the shoreline is under Cass County or US Forest Service administration. Barnum Lake is managed primarily for largemouth and smallmouth bass and secondarily for northern pike, bluegill and black crappie. There is an abundant largemouth bass population present in a wide range of sizes of largemouth bass present in Barnum Lake, with fish up to 21.5 inches sampled. Smallmouth bass were not as abundant as largemouth, however fish up to 18 inches were found. Black crappie were abundant in the 2001 DNR sampling, and fish from 5 to11 inches were found. Northern pike were also abundant and the population had a good size structure. Numbers of bluegill present compares favorably with other lakes of this type. Though most bluegill sampled were small, there was a respectable number of fish 6 inches or greater. Pumpkinseed sunfish, rock bass, and yellow perch can provide action for panfish anglers on Barnum Lake as well. 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-size fish. Releasing these fish can help maintain balance in the fish community in Barnum Lake and provide anglers with opportunities to catch more and larger fish in the future. Most of the land around Barnum Lake is privately owned. In 1988, a lake survey crew counted 28 lake homes around the shoreline, and by 2001 this number had increased to 40 homes. With increasing use of lakeshore areas by people, it is essential that shoreline areas be protected from degradation. 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…
