Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

SURFACE-WATER RECORDS
PERIOD OF RECORD - Continuous-record discharge station, April 2010 to current year.
GAGE - Water-stage recorder with telemetry and crest-stage gage. Datum of gage is 783.53 ft above NAVD of 1988.
REMARKS - Records fair, except for estimated discharges, which are poor. Flow regulated by Canistear Reservoir, Oak Ridge Reservoir, and other small upstream lakes and ponds.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 2,980 ft³/s, Aug 28, 2011, gage height, 9.21 ft; minimum discharge, 0.50 ft³/s, Dec 7-8, 2014.
WATER-QUALITY RECORDS
PERIOD OF RECORD - CONTINUOUS DATA: Dissolved Oxygen, Apr 2010 to Oct 2014. Dissolved Oxygen (Percent of Saturation), Apr 2010 to Oct 2014. Specific Conductance, Apr 2010 to Oct 2014. Water Temperature, seasonally Apr through Oct, 2010 to current year.
REMARKS - The accuracy of continuous water-quality data can be found here.
