Benjamin Lake is a 33-acre lake with a maximum depth of 128 feet located within the Chippewa National Forest 12 miles north of Pennington in Beltrami County. An historic CCC encampment is located on Benjamin Lake, and is maintained as an interpretive learning center by the US Forest Service. There is a public access site located on the southwest shore off of State HWY 39, also known as the Scenic Highway. There is also an accessible fishing pier which provides shore fishing opportunities, as well as a public swimming area.
Benjamin is managed as a stream trout lake and has been stocked annually with fingerling rainbow trout. There has been a decline in the quality of the trout fishery in recent years due to the presence of high numbers of small bluegill and yellow perch, which compete with young trout for available resources. As a result, growth and survival of stocked fingerling trout has been poor. To address this situation, rainbow trout stocking will be switched from fall fingerlings to catchable-size yearling fish which are 9 to 11 inches in length. This should alleviate many of the factors that were limiting trout growth and survival and will be immediately noticeable to anglers. The shift in stocking strategies will be implemented in the spring of 2012. Benjamin is scheduled to be stocked prior to the stream trout lake fishing opener of May 12, 2012. Benjamin Lake also received a stocking of surplus broodstock brown trout (2 to 4 lbs/fish) in the fall of 2011.
Benjamin Lake does hold some quality-size yellow perch, which have managed to grow despite the extremely high abundance of bluegill and perch in the lake. The 2011 population assessment captured perch up to 12.9 inches in length, with 15% of the trap net catch greater than 10 inches in length.
