- South Dakota Game, Fish and Parks
Anglers in western South Dakota typically spend over 200,000 angler hours fishing between Angostura, Belle Fourche and Shadehill in a given year, highlighting their importance to regional recreation and generation of economic benefit to the region. Understanding Walleye population dynamics in these reservoirs in critical to the evaluation of current regulations and modeling the impacts of potential regulation changes. This study will provide data on Walleye growth, recruitment and mortality rates, and provide additional needed information about Walleye anglers and levels of Walleye exploitation in these reservoirs which will be used to model the impacts of different regulations on these important fisheries. Collection and analysis of the data will allow for informed decisions regarding the future status of Walleye regulations in western South Dakota.
