PROVISIONAL DATA SUBJECT TO REVISION
Click to hidestation-specific text
The 15-minute precipitation data for this station are temporary and will only be displayed for 120 days. Although the instrumentation is calibrated at least once/year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.

LOCATION.--Lat 42°20'53.2", long 77°42'22.5" referenced to North American Datum of 1983, Steuben County, NY, Hydrologic Unit 02050104, at Almond Dam on Canacadea Creek, 2.0 mi northeast of Almond, and 3.0 mi upstream from mouth. Located adjacent to State Highway 21, between Hornell and Almond.
DRAINAGE AREA.--55.8 mi².
PERIOD OF RECORD.--July 1949 to September 1952 (month-end elevations and contents), October 1952 to September 1968 (daily elevations at 2400 and month-end contents), October 1968 to September 1985 (daily mean elevations and month-end contents), October 1985 to September 2013 (month-end elevations and contents), October 2013 to current year (daily mean elevations). Prior to October 1970, published as "Almond Reservoir near Almond."
REVISIONS HISTORY.--WSP 2103: Drainage area.
GAGE.--Water-stage recorder. Reservoir elevation record is available in ft above NGVD of 1929 and ft above NAVD of 1988. To convert NGVD of 1929 elevations to NAVD of 1988, subtract 0.34 ft. Gaps in record during the period prior to May 1965 are associated with the water surface being below the lowest intake (elevation, 1,231.00 ft above NGVD of 1929).
COOPERATION.--Capacity table provided by Corps of Engineers, 1952.
REMARKS.--Elevations listed herein are in ft above NGVD of 1929. Lake is formed by earthfill dam with concrete spillway, completed by Corps of Engineers in June 1949 for flood control; first used for flood regulation on Mar. 28, 1950. Usable capacity, 14,800 acre-ft between elevations 1,229.0 ft (sill of gates) and 1,300.0 ft (crest of spillway). No dead storage. Figures given herein represent usable contents. Discharge is controlled by the operation of three gates. Water is stored during high flows and released when downstream conditions warrant. Lake is used for flood control and recreation.
