Fish Status

BLUEGILL

Very Good

Little Grassy Lake bluegill abundance in spring 2019, as measured by catch-per-unit-effort, was substantially higher at 93 per hour. The proportion of these fish larger than 6 inches was 59%, bluegill larger than 7 inches made up 21% of the sample. Average bluegill body condition was just below the desirable range.

LARGEMOUTH BASS

Very Good

The Little Grassy Lake largemouth bass population is generally well balanced, and contains fish ranging in size from fingerlings to trophies. In 2021, bass abundance was higher-102 were collected per hour of electrofishing (goal is 60/hour). Bass quality, as measured by length, was easily within the management plan goal range with 51% larger than 12 inches and 14% over 15 inches. As is often the case in clear, infertile lakes, bass body condition (measured by relative weight) remained at the lower range of the goal but the 2021 sample included bass over 7 pounds. Site regulation: 12 to 15 inch protective slot limit, 6 per day creel.

REDEAR SUNFISH

Very Good

Little Grassy Lake redear abundance in the spring 2021 sample was nearly over double the previous sample at 73 per hour of electrofishing. Redear quality, based on length continued to be very impressive, with 52% of fish over 7 inches, and 2% larger than 8 inches, with several fish exceeding the 9 inch mark. Redear body condition dipped just below the lower end of the management plan goal range.
