The Credit River in Savage, MN, one block south of Highway 13.
This river (really a small creek) normally is pretty-much a drainage ditch in this area, but during the spring and after heavy rains it turns into a challenging and fun kayak run (further upstream). As currently pictured in the video it is too dangerous (and way too cold!) to run. Maybe with some wetsuits or drysuits we will give it a run in a month or so...
