The water it stands in

Falls River.

We hold no coldwater classification for this river, so the page makes no claim about one. The gauge is here because it stands close to water that does carry a designation.

Snapped to NHD reach Falls River (60003200035902), 25.7 m away. That join is what lets the app paint this gauge's reading onto the reach it measures.
