First Whitnall Park Dam

As you encounter a backwater in the park, you will approach the first of two dams. At low flows, a boat would likely grind to a stop on the lip, making it necessary to use hands or paddle to push across the brink of the dam, or 'throw' your weight back (on approach) then forward (as your boat encounters the dam) to scrape across it and drop into the pool below. At flows high enough to not scrape across the lip, there will be a nasty uniform boil at the base that it would take a well-timed and excuted 'boof', and strokes to paddle out of the boil here.

This is very much in sight of the park road just downstream, so it is a fairly 'high visibility' location where one should not dawdle, as your presence may draw attention and result in an encounter with authorities.
