River Description


Removal of a dam has revealed a small ledge. Stream remediation involved removing sediment, lining the shores with quarried-rock, and placement of three rock-arch ('wing dam') rapids in about a quarter-mile of this creek as it heads toward (and under) River Road, prior to the confluence with the Fox River. Barely a half-mile upstream of this confluence on the Fox lies the Marge Cline Whitewater Park (a brief whitewater course in a bypass-channel around a dam). At times of peak snowmelt and after significant rains, there will be enough water in this creek to (perhaps) provide some change-of-pace/counterpoint to the features in that course. (In fact, when this creek has sufficient flow for a run, it is likely the Fox will be running a bit high for best play on its whitewater course.) There is a blog which chronicled the entire dam removal and remediation process. The page of the blog showing the 'restored' creek, with flow, is available at: Waterdog Journal.
