Seventh Crow Wing is located two miles south of Nevis in Hubbard County. Seventh Crow Wing has a surface area of 254 acres and a maximum depth of 40 feet. There is no public access on the lake, however, there is a county-owned access on the outlet channel (Crow Wing River), west of county road #13. This is an undeveloped access that is only suitable for small or carry-in boats. The Minnesota Department of Natural Resources (DNR) has classified Minnesota's lakes into 43 different types based on physical and chemical characteristics. Seventh Crow Wing is in lake class 31. Other area lakes in this same classification include: Second, Fifth, Sixth, and Eighth Crow Wing lakes, Duck, Hinds, and Lower Twin. Seventh Crow Wing provides fishing opportunities for walleye, northern pike, largemouth bass, and panfish.
Walleye were sampled in high numbers (13.5 walleye/gillnet), above the management goal of 7.0 walleye/net and well above the range "typical" for this lake class. Walleye abundance in past has generally been near or above the management goal. Good numbers of walleye in the 16-18 inch size range were sampled. The walleye population in Seventh Crow Wing is being maintained by a combination of natural reproduction and stocking by the DNR. Seventh Crow Wing is stocked with walleye fingerlings in odd numbered years. Yellow perch, an important forage species for walleye, were sampled in good numbers. The yellow perch in Seventh Crow Wing are small in size with few fish an acceptable size for angling.
Present and past surveys have shown that Seventh Crow Wing is able to maintain a low to moderate northern pike population composed of moderate to quality sized fish. The northern pike gillnet catch of 1.0 pike/gillnet is below the range "typical" for this lake class, but similar to past surveys. While numbers are low, Seventh Crow Wing is able to produce some large pike due to the combination of a good food supply of white sucker and tullibee (cisco) and fast growth rates.
Seventh Crow Wing supports good populations of panfish and largemouth bass. Anglers will find good numbers of bluegill in the 6-8 inch range and black crappie in the 9-11 inch range. Good largemouth bass habitat of submerged and emergent aquatic vegetation is found in Seventh Crow Wing.
Other species sampled included high numbers of white sucker and bowfin (dogfish) and moderate numbers of pumpkinseed and rock bass. Brown bullhead, yellow bullhead, golden shiner, and green sunfish were sampled in low numbers.
