Mt. Morris Dam and the Genesee River Gorge are just a hop and skip north of Ridge, NY.
Go north about one mile on route 408 (Mt. Morri-Nunda ROad), from Ridge, and connect to the Park Road. Then drive northwest on Park Road another mile to the visitors center.
The dam was built in the 1940s to help prevent the recurring spring floods caused by the swelling of the Genesee River. Countless properties were ruined each year and the Army Corps of Engineers stepped in with this solution.
The park has a visitor center, river overlook, small memorial garden and a picnic area (we ate lunch here). The visitor center is staffed by two ladies who will talk your arm off; very nice ladies but very chatty and informative. There is a 15 minute movie about the dam, its construction and the river. Normally they have special displays (civil war artifacts, boy scout campout events, fossils found in the area, et.al.) that change periodically and are set up in the main entrance foyer. The rest of the visitors center is display boards and cases showing aspects of the dam and the people involved and general info about civil engineers.
There are two restrooms at the park, one in the visitor center for use during its hours and one outside that is more of a portapotty.
The center is completely free and handicap-accessible. The overlook area is fenced for your protection and a bit difficult to get at alone with a wheel chair but can be accessed with a little help. The center's hours are normally 8am to 4pm and they have walking tours on scheduled days and times (call the number below).
