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.

Hazel Lake is a 15-acre lake with 0.71 miles of shoreline and a maximum depth of 38 feet located northeast of Hackensack, MN. There is a US Forest Service public access located on the south shore. Hazel Lake offers Rainbow Trout fishing in a remote, wilderness setting. The lake is entirely within the Chippewa National Forest and the shoreline is undeveloped. Hazel Lake is one of four designated stream trout lakes in the Walker Fisheries Management Area. Other stream trout lakes in the Walker Management Area are Diamond, Perch, and Teepee Lakes. Rainbow Trout were initially stocked in Hazel Lake in 1959. Rainbow Trout do not reproduce in the lake and the population is supported entirely by stocking to provide a unique angling opportunity. Rainbow Trout stocking success is dependent on the absence of introduced species. The average length of Rainbow Trout sampled in 2023 was 11 inches and lengths ranged from 10 to 13 inches. People can have significant impacts on lakes and the fish populations they support. Harvest, lakeshore development, removal of shoreline vegetation, and introductions of invasive species can all adversely affect fish populations. Currently no aquatic invasive species (AIS) have been identified in Hazel Lake. AIS are moved from infested to non-infested waters by anglers, boaters, and lake shore owners and can adversely impact lakes and fish populations. To avoid spreading AIS, lake users are required to remove all aquatic plants or animals from their watercraft and drain all water from their boat before leaving the access. If you suspect an infestation of an invasive species in this lake, save a specimen and report it to a local natural resource office. Additional information on all of these topics can be found on the DNR website (www.dnr.state.mn.us) or by contacting the Walker Area Fisheries office.
