Other productive lakes include Canyon Lake, Horsethief Lake, Legion Lake, Center Lake, Bismarck Lake, Sylvan Lake, Stockade Lake and Deerfield Lake. Deerfield Lake is a remote year-round lake near Hill City holding rainbows, brookies, and splake, some of which reach six to eight pounds. Most can be floated from a belly boat or other personal watercraft and some allow boats. Fishing from shore works well too on the smaller lakes. Other area lakes worth fishing include Sheridan, Iron Creek, Mirror and Angostura Lakes.
Canyon Lake is located in a city park in Rapid City.
Smaller Streams Look at a map of the Black Hills region and you will see streams crisscrossing it every which way. The largest feeder stream is Castle Creek above Deerfield Lake, a nice little walk-in stream loaded with brown and brook trout. Slate Creek is a worthwhile and little known tributary of Castle Creek, difficult to access but holding larger fish in its waters than it should. French Creek, in Custer State Park, surprisingly holds lots of trout in its riffles. Spring Creek is shallow and accessible, and in its clear low waters reside amazingly big brown and rainbow trout that rank among the most finicky in the Black Hills.
