The French Creek valley was an important early industrial region, particularly iron, in the United States.
Hopewell Furnace National Historic Site along French Creek interprets this history.
The Phoenix Iron Works site in Phoenixville, an active iron and steel producer from colonial times until the late 20th century, sits astride the creek just before it joins the Schuylkill.
In 1994, the Green Valleys Association (GVA) with its 38 co-petitioners filed a petition with the Pennsylvania Environmental Quality Board for the upgrade of the French Creek watershed from a designation of High Quality (HQ) to Exceptional Value (EV).
In 2003, Green Valleys and its 48 co-petitioners successfully filed a petition to obtain an upgrade from HQ to EV of the lower reaches of French Creek, from the Kennedy Covered Bridge in East Vincent and East Pikeland Townships upstream to PA 100 in South Coventry Township as well as the entire Beaver Run.
