Eagle Lake is located in Hubbard County, seven miles north of Park Rapids. Eagle Lake has a surface area of 423 acres and a maximum depth of 77 feet. There is a public access located on the west shore of the lake. Eagle Lake is part of the Island, Eagle, and Potato chain of lakes, with connections to Island Lake upstream and Potato Lake downstream. Boating access in the river connecting these lakes is possible with small to medium size boats, but conditions can vary with water level fluctuations.
The Minnesota Department of Natural Resources (DNR) has classified Minnesota's lakes into 43 different types based on physical, chemical, and other characteristics. Eagle Lake is in lake class 25. Class 25 lakes are generally characterized by being deep, clear, hard water lakes, with an irregularly shaped shoreline. Other class 25 lakes in the Park Rapids area include Bad Axe, Belle Taine, West Crooked, Third Crow Wing, Island, Big Mantrap, Little Mantrap, Ojibway, Little Sand, Spider, Straight, and Two Inlets.
Eagle Lake is well known for its walleye fishery and is a popular fishing spot, especially early in the season. Walleye abundance was within the normal range for similar type lakes and at the current management goal. Walleye abundance in past surveys has been fairly stable and similar to the 2012 survey. Anglers will find good numbers of walleye in the 14-18 inch size range, with walleye measured up to 27 inches. Eagle Lake is currently stocked with walleye fingerlings during odd numbered years. Yellow perch, an important forage species for walleye, were sampled in very low numbers. Yellow perch abundance in past surveys has generally fluctuated from moderate to high numbers.
Northern pike were sampled in moderate numbers, within the normal range for similar type lakes. Northern pike abundance in past surveys has fluctuated from low to moderate numbers. Sampled northern pike had an average length and weight of 20 inches and 1.7 pounds, with pike measured up to 31 inches. While dominated by small pike, Eagle Lake can produce a few large fish. Important forage species such as tullibee (cisco), white sucker, and shorthead redhorse are present providing the right conditions for growing large pike.
While not known as a panfish lake, Eagle does support fishing opportunities for black crappie, bluegill and pumpkinseed. Black crappie were sampled in low numbers, similar to past surveys. Anglers can expect to find black crappie in the 9-12 inch size range. The bluegill population in Eagle has been increasing. Bluegill were sampled in moderate numbers, within the range for similar type lakes. Bluegill abundance in surveys prior to 2000 was low, well below the normal range for similar type lakes. Anglers can expect to find bluegill and pumpkinseed in the 6-8 inch size range.
Other species sampled included moderate numbers of rock bass and low numbers of brown and yellow bullhead. Largemouth bass are present in Eagle Lake but numbers are low compared to other area lakes.
Currently no aquatic invasive species (AIS) have been identified in Eagle Lake. To avoid spreading AIS, lake users are required to remove all aquatic plants from their watercraft and drain all water from their boat before leaving the access.
