Double T Lake

Crappie spp.

Average

In 2024, the black and white populations were sampled by the collection of 27 black crappie and 14 white crappie in the spring trapnet survey. The average relative weights for these fish were 86 and 89 respectively. The black crappie indices showed 15% of the fish over 10 inches, and the white crappie indices showed 29% of the fish over 10 inches. A low-density crappie population is currently present with large fish available to anglers. The established regulation is a minimum size limit of 10 inches and a creel limit of 25 fish per day.

Muskellunge

Average

In 2024, 7 muskie were collected in the spring trap survey. These fish ranged from 30.3 to 37.6 inches long. The average body condition was good with a Wr value of 94. 66 fish were stocked in 2017, 2021 and 2024. The muskie stocking for Double T Lake was adapted to a stocking once every 3rd year starting in 2017. The goal is to maintain a low density of muskie that can grow fast and maintain good body condition.

Largemouth Bass

Good

The Largemouth Bass population was sampled by 164 stock size fish in 2024. The current bass regulation of a 21-inch minimum size limit and 1 fish per day was an effort to protect the initial population in the lake and to build this population up. In the 2024 sample, the PSD was 68, the RSD14 was 25, the RSD 16 was 17 and the RSD18 was 10. The RSD16 and RSD18 values were well below the yearly average since 2014. The Largemouth Bass indices since 2013 have been very high for a bass population. The catch rate was 1.8 in 2024 and has ranged from .6 to 1.8 fish per minute over the last 10 years. The average Wr was good at 90 in 2024.

Bluegill

Poor

The Bluegill size structure remained low according to the 2024 electrofishing survey results. The five-year trend appears to be a Bluegill population with a top size under 7.0 inches in length. The competition from the current gizzard shad and carp population may limit the ability of the Bluegill population to improve to a good status.
