About Grass Lake
Fishing & license
South Dakota fishing license
South Dakota also requires a Habitat Stamp ($10 resident / $25 nonresident) for buyers 18 and older, so the real all-in cost is $41 resident and $105 nonresident.
Residents and nonresidents under age 18 do not need a fishing license and may take their own daily limits. Anyone 18 or older must have a license plus a Habitat Stamp ($10 resident / $25 nonresident, once per license year; not required with one-day fishing licenses). Residents 65 and older get reduced-price licenses rather than an exemption — they must buy the Senior Annual Fishing ($17) or Senior Combination ($43) license. · Fishing in South Dakota is open year-round — there is no statewide closed season, only species- and water-specific limits (special drawings apply to paddlefish snagging/archery). Annual licenses for the 2026 license year are valid December 15, 2025 through January 31, 2027.
