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.

DRAINAGE AREA - 30 mi², approximately.

SURFACE-WATER RECORDS

PERIOD OF RECORD - August 1971 to 1976, 1990 (discharge measurements only). Daily stage and discharge from October 2008 to current year.

GAGE - Water-stage recorder and data-collection platform. Datum of gage is 23.94 ft above NGVD of 1929 and 23.25 ft above North American Vertical Datum of 1988.

WATER-QUALITY RECORDS

PERIOD OF RECORD -

Water-quality monitors installed January 27, 2016. Period of record from January 27, 2016 to current year.

INSTRUMENTATION -

Water-quality monitor consisting of temperature, specific conductivity, dissolved oxygen and pH.

An additional monitor measures only nitrate.

REMARKS - Extremes for period of record are based on recorded values and may have been exceeded during periods of no record. January 2016 to current year, water temperature, specific conductance, dissolved oxygen, and nitrate published as instantaneous maximum and minimum, and daily mean; pH published as instantaneous maximum and minimum, and daily median.
