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.

Trillium Lake, also known as Lizzard Lake, is a 136-acre lake located near Hackensack, MN with no public access. With a maximum depth of 48 feet, approximately 67% of the lake is less than 15 feet deep. The Minnesota Department of Natural Resources (MNDNR) has classified Minnesota's lakes into 43 different classes based on physical, chemical and other characteristics. Trillium Lake is in Lake Class 32; lakes in this class are generally large, high littoral area, turbid and irregular shaped lakes. This lake is primarily managed for northern pike and largemouth bass and secondarily for bluegill and black crappie Northern pike were abundant and the size structure consisted of larger fish. Northern pike up to 33 inches were sampled and the mean length was 25 inches. A fair number of largemouth bass were present, but they were small. Bluegill were abundant, however most were small. Other fish species available for anglers to catch include black crappie, brown bullhead, pumpkinseed sunfish, yellow bullhead, and yellow perch.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 Trillium 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…
