Downstream it flows through Bob Creek Wildland Park[5] and Black Creek Heritage Rangeland.[6] Oldman Dam and Oldman River are other Provincial Recreation Areas established along the river. The river and some of its tributaries have formed coulees in Southern Alberta, and the strata revealed by these formations guide local prospectors to ammolite deposits. FishThe Oldman River contains fish species such as rainbow trout, cutthroat trout, bull trout, brown trout, hybrid trout species ("cutbow" rainbow and cutthroat cross), mountain whitefish, pike, walleye, lake sturgeon, catostomidae, goldeye, and minnows.{{citation needed|date=July 2017}} See also
