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 -
DISCHARGE: August 2014 to current year.
GAGE HEIGHT: August 2014 to current year.
DISCHARGE: August 2014 to current year.
GAGE HEIGHT: August 2014 to current year.
GAGE - Datum of gage is 770 feet above National Geodetic Vertical Datum (NGVD) of 1929 (from topographic map).
