Walleye abundance was low but consistent in previous years, but dropped further in 2016. The few walleyes that were sampled were larger, from 17-24.5 inches. Yellow Perch are important forage for Walleyes and Northern Pike, and their numbers were in line with other class 31 lakes. Perch had an average size of 6.5 inches and were sampled up to 9.5 inches.
Northern Pike abundance was similar to class 31 lakes, and on the high end of past surveys of Hattie. Pike ranged from 12 inches to 30 inches in length. The average size of 18.5 inches and 1.4 pounds were in line with past surveys.
Largemouth Bass were sampled in high numbers compared to class 31 lakes, and on the high end of past surveys of Hattie. Fish ranged from 6.5 to 16 inches, with fish spread out evenly over this range.
Angling opportunities for panfish include Black Crappie, Bluegill and Pumpkinseed. Black Crappie numbers were in line with lake class 31 lakes, and most crappies were 8-10 inches. Bluegills and Pumpkinseeds were sampled in higher numbers compared to recent years, with most fish 4.5-7.5 inches long.
