Lake Cascade produces another state record perch Congratulations to Adam Mann of Mosinee, Wisconsin, on landing the latest record yellow perch from Lake Cascade. After being weighed locally on a certified scale and inspected by a Fish and Game biologist, Mann was awarded a new certified-weight state record for his 3.22-pound perch that was 16.25-inches long. Mann landed the monster perch while ice fishing on Tuesday, March 9. As an avid ice-fisherman, Mann and several friends made the long trek to Idaho in search of trophy perch. Although fishing had not been hot that day, they had been finding a some large perch throughout the day.
