Description

A dam (creating Comus Lake) spills flow under N.Terrace Street. The dam is being rebuilt (2024/2025) and presently has boards in vertical slots. Unsure if it will have bottom spill lift-gates or if it will be top spill. Either way, water will sheet shallow across cement splash pan under the road. Midway under the bridge it meets the downstream pool height and creates a wave/hole. At many flows, this is likely playable.

Park and play is possible, and likely a 'best bet' for true whitewater boaters, ignoring the rest of the run, other than perhaps driving to Klug Road if you're interested in stalls and squirts in currents there.

The pool is decent sized, and flow exits to the left, spilling over rock rubble. At high flows, this will be 'washed out'. At lower flows, it will just be rocky. (The 'featured photo' atop this listing shows this rocky rubble at ~260 cfs.)

By our listed take-out, drainage area increases to ~202 square miles (more than 6x the put-in location).
