Records good except those for estimated daily
discharges, which are fair. Diversion from Carrington Creek, a
tributary upstream from station, by City of Hornell for municipal
supply; effluent from wastewater treatment plant enters river
downstream from gage. Since March 1940, flood flows regulated by
Arkport Reservoir (station 01521000), and since June 1949, by Almond
Lake (station 01523000); normal regulation occasionally sufficient to
affect figures of monthly runoff. Telephone and satellite gage-height
telemeters at station.
