The website for StreamTeach has detailed descriptions and illustrative photos. Ranges from small waves and good play holes along the Missouri banks to big-water wave trains below the Illinois side water tower. Best park-and-play holes and waves (Rookies, Cobblestone, Primo) abut the St. Louis City Water Treatment Plant. Since 9/11 the City enforces trespass prohibitions on its property but leaves play boaters alone who remain in their boats on the Mississippi. One easily avoidable low-water dam danger 100 yards off the water treatment bank is near a good play hole, Salmon Run, formed when the gauge is below nine feet. Typically the Chain is playable from mid-August through November. The StreamTeach message Board is a good place to pick up paddlers who play the river often and know play and danger spots.
