Increased flash flooding has accompanied dense residential development of the Fishpot Creek watershed in Valley Park, St. Louis County. Riprap has been placed to slow the dramatic channel erosion that threatens homes and roads. The high-energy bedforms, the course gravel, the erosion, the deep channel incision below the natural floodplain, and the lack of perennial flow in the creek are all consequences of unnatural flash flooding.
