French Creek has a naturally reproducing population of Brown Trout. Last sampled in 2011 found 2,100 Brown Trout per mile with fish up to 20-inches. This is an estimated population and actual trout numbers will be higher. The upstream segment (upstream of the confluence with the West Branch of French Creek) also has a naturally reproducing South Pine strain Brook Trout population with some wild Brown Trout in this area. Sampling in 2017 showed 220 Brook Trout per mile with fish up to 11-inches collected. Brown Trout sampled in this area numbered 700 fish per mile with fish up to 16-inches. There is a catch and release regulation for Brown Trout only and an artificial lure only rule on French Creek. Primitive camping is allowed on the French Creek Wildlife Management Area. Parts of the stream are on private property where only angling is permitted.(2022)
