Totally low; nothing but a scrape.
Most boaters are best advised to put-in from the park (grassy area) river-right just below the dam.
Only a very few paddlers are likely to take the time explore from river left, either parking on Water Street near Brown Court or (carrying from the take-out parking, crossing the Mason Street bridge, then up a path on that side of the river.
Extreme river-left of the dam may be run (at some flows) but will be a hard landing on water sheeting shallowly across bedrock.
Otherwise, find a spot to launch into to paddle the runout.
