Explore Black Hills trout streams in South Dakota: the creeks GFP stocked this year, with counts and dates, the Rapid, Spearfish and Castle Creek main stems, and the streams the state classes as coldwater fish waters, with public land, access and river gauges.
Check before you fish. Access, stocking and regulations here come from South Dakota's own data and can be out of date. Posted signs and landowners' wishes come first, and private land needs permission. The rules that apply are in the South Dakota fishing handbook, and you need a valid fishing license.
Bold where the stream crosses public land; faint and dashed across private land. Gauges are measurement stations; a nearby gauge may be on a different stream.

South Dakota publishes no map layer of its trout streams. Stocked creeks come from GFP’s stocking report for this year; GFP stocks named sections, and the line shows each whole creek within the Black Hills. Rapid, Spearfish and Castle creeks are the three watersheds GFP’s Black Hills streams plan focuses on.
The other Black Hills streams are the state’s coldwater beneficial-use classes: permanent (cold enough to support trout year-round) and marginal (trout for part of the year or in places). They are water quality classes, not fish surveys, and much of the land along them is private. Lines stop 8 km beyond the national forest boundary, so plains reaches are left out. Lakes are left out.
Highlighted banks adjoin mapped open-access public land, with a roughly 20-meter bank tolerance. Dimmed water has no adjacent open-access parcel recorded in this source. Neither determines legal entry, rights of way or permission to cross private land. Check signs, property rules and the current fishing regulations.
Access markers are source facility locations within about 800 meters of mapped water, not verified parking spaces or guaranteed entry to a particular reach. River-gauge readings describe the gauged location; a nearby gauge on another stream is shown as context.
