Should the boundary for Lower Delaware National Wild and Scenic River extend all the way to the Nockamixon State Park Dam? I cannot find any evidence to prove or disprove, and the NPS site for it simply links back to OSM for its maps page.

Additionally, for "fishing and boating," it does not list the frequent dam releases that occur for kayakers to ride down the creek on.

On the page for Ralph Stover State Park, it mentions nothing about the LDNWS, although they advertise whitewater opportunities, and mention that permits for it can be picked up in their park office.
