Overview
Lake Thompson is a natural lake in SD. It is managed by South Dakota GFP.
The basin is characterized by about 16,400 acres of surface area. Shoreline and bottom character vary from protected coves and flats to deeper water, supporting a mix of open-water and nearshore habitats.
Lake Thompson supports recreational boating and fishing. Public access is through area ramps, parks, and shoreline facilities where provided by the operator. Fishing and boating regulations are set by the relevant state wildlife agency.
Lake Thompson is not operated to a classic reservoir full-pool curve. Where a gauge exists, water-surface elevation is the reference. Conditions still matter for boating, fishing access, and shoreline use.
