Too low for whitewater. May be floated, but will be 'grungy'.
The recommended put-in is relatively midway in the park, where a new bridge spans the river. You'll have to park a little more than 100 yards away and carry to the put-in. (It may be possible to temporarily park in a gravel drive near a restroom building right at the river, offload your boat(s), and then move the car to the parking lot.) Access is best on the downstream side of the bridge, where stonework steps lead to water's edge, and provide a handy launch.
