Thompson Northeast Boat Ramp provides access to Lake Thompson, one of South Dakota's largest natural lakes at over 12,000 acres.

However, user reports indicate this ramp experiences maintenance issues including sand buildup that creates shallow water (2-3 feet at the prop) and poor traction, and is affected by prevailing south/southwest winds that can churn up rough water conditions.

Alternative ramps on the west and northwest sides of the lake may offer better conditions depending on wind direction.
