About the Spring Creek
Spring Creek rises in the central Black Hills and runs east past Keystone, through the hills toward Sheridan Lake and eventually out onto the plains near Rapid City. The name is earned rather than decorative: the creek gains a substantial part of its flow from limestone springs in the Madison and Minnelusa formations, and that groundwater input gives it a stability of flow and temperature that a surface-fed mountain stream in this country would not have.
That stability is what makes it a trout stream worth driving to. The Black Hills sit in an otherwise dry part of the continent, and many streams here run thin and warm by late summer. Spring Creek holds up. The gauge near Keystone reports discharge and stage, and while the creek does spike after the heavy spring and early summer thunderstorms that this region gets, it returns to a fishable level quickly and then holds it. Reading the gauge before a trip is mostly about avoiding the day or two after a storm.
Brown trout are the principal fish and are largely wild and self-sustaining in the better reaches, holding under the cut banks, against the limestone ledges and in the deeper pools beneath the pines. Rainbows are present and supported by stocking in the more accessible water. Brook trout occupy the colder upper reaches and the smaller feeder springs. The fishing is small-stream work with a careful approach, and the creek rewards anglers willing to walk away from the road crossings. Keystone itself is the gateway town for Mount Rushmore and is extremely busy through the summer, which is worth planning around: the tourist season affects traffic and lodging far more than it affects the fishing.

Hill City - a short drive west, with services and access to the upper hills water.

Seasons
Spring: snowmelt and storms keep it high and coloured at times, but it fishes well between events as it warms.
Summer: the creek's real strength, holding cool and steady on spring flow while the tourist traffic ignores it.
Fall: excellent, with brown trout colouring up and moving to spawn, and the hills empty of visitors.
Winter: cold and often iced in the open reaches, though spring-fed sections stay open and fish on mild days.
