Crystal Lake experienced a summer fish kill in 2021. Follow up fish surveys found good numbers of crappie survived the kill, but the size structure favored smaller fish. Walleye, Northern Pike, and Largemouth Bass populations severely declined as a result of the 2021 fish kill. Largemouth Bass, Walleye, and Bluegill were stocked in the fall of 2021. Northern Pike will be stocked in the spring of 2022.(2022)
