About Spring Creek

A smaller, freestone Black Hills stream with a dedicated following among local fly anglers. Spring Creek runs through a mix of public and private land near Custer, offering quality pocket water fishing for those willing to explore. The stream's intimate size rewards accurate casting and stealthy approach — bigger fish hold in undercut banks and deeper pools. Proximity to Custer State Park adds scenic appeal.
