Project Overview

Arkport dam is an earthfill structure, 1,200 feet long, rising 113 feet above the streambed, with a concrete spillway and an ungated outlet in the right abutment.  This project is normally a dry dam; however, water is impounded after heavy rains.  The reservioir created by the dam has a storage capacity of 7,900 acre-feet at spillway crest and has an area of 190 acres when filled to that level.  The project controls a drainage area of 31 square miles, 20 percent of the watershed of the Canisteo River upstream from Hornell.  An additional portion of the watershed is controlled by Almond Lake.  This project forms part of the protection for Hornell, Canisteo and Addison, and reduces flood heights at other localities on the Canisteo and Chemung Rivers.  It contributes to Executive Order 13508 goals to protect habitat and water quality within the Chesapeake Bay watershed.  The project is operational and does not have any recreation features.

LOCATION:  Arkport Dam is located near Hornell, New York, on the Canisteo River, a tributary of the Chemung River, which flows into the Susquehanna River. 

AUTHORIZATION:  The project was authorized by the Flood Control Act of June 22, 1936, as amended by the Flood Control Act of June 28, 1938.
