Dam/Weir?

A small weir/dam appears to exist at this point. It is likely that (at flows required to run Tioga) this will be a 'non-event', awash in flow with perhaps no sign of its existance. However, in case that assessment is wrong, be alert. It is possible it may (at some flows) create a keeper hydraulic . . . or . . . maybe a playable feature (for those who know the difference).
