Figure 3.5-2. PSD for Walleye in Seminoe Reservoir Study Area

Walleye

For Walleye, minimum length categories are sub-stock (0 millimeters [mm]), stock (250 mm), quality (380 mm), preferred (510 mm), memorable (630 mm), and trophy (760 mm). Figure 3.5-2. provides the PSD for Walleye resulting in a value of 54.6 indicating that the population of Walleye are well balanced in Seminoe Reservoir and includes a variety of catchable fish in the stock size class or larger.

Brown Trout

For Brown Trout, minimum length categories are sub-stock (0 mm), stock (200 mm), quality (300 mm), preferred (400 mm), memorable (500 mm), and trophy (600 mm). Figure 3.5-3. provides the PSD for Brown Trout resulting in a value of 100 percent and shows that the population of Brown Trout contain many large fish and few younger age classes. Brown Trout are not stocked as part of the WGFD Seminoe Reservoir stocking program (HDR 2022b). Brown Trout generally utilize riverine and tributary features for spawning and return to Seminoe Reservoir for the remainder of their life cycle. Spawning in the tributaries of Seminoe Reservoir where young-of-year (YOY) fish likely reside could explain what appears to be skewed data for Brown Trout in Seminoe Reservoir, as these early life stages are not present in the areas that were sampled.
