Totally low; nothing but a scrape.
The most usual take-out will be from the pool immediately at the base of the final ledge/drop.
The easiest egress will be from river-right eddy, carrying up onto a near-river grassy strip, carrying toward the buildings (upstream), to carry up wooden stairway to the parking area. The rows of parking nearest the river are all reserved for tenants of these units, so boaters will need to park in the areas along the aisle nearer the street.
