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.

On 2/26/2020, discharge record for the period of 2/18/2017 through 03/02/2020 was revised due to instrumentation programming errors. Gage height data was corrected for the entire period with offsets and gage height corrections causing discharge revisions to the data set.
SURFACE-WATER RECORDS
PERIOD OF RECORD - Annual maximum, water years 1979 to 2010. Continuous-record gage-height station with annual maximum discharge, water years 2011 to current year. Miscellaneous and occasional low-flow measurements, water years 1979-85, 1988 to 2006.
GAGE - Water-stage recorder with telemetry and crest-stage gage. Datum of gage is 208.84 ft above NAVD of 1988.
REMARKS - Peak discharges above 240 ft³/s from rating curve extension on basis of contracted opening computation of peak flow. Annual peak data can be obtained by selecting Peak streamflow from the 'Available data for this site' drop-down menu above or by using this link.
EXTREMES OUTSIDE PERIOD OF RECORD - Maximum discharge, 3,100 ft³/s, computed by State Water Policy Commission at Squaw Lake Dam, 0.2 mi upstream of gage, Jul 23, 1945, gage height, not determined.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 2010 ft³/s, September 1, 2021, gage height, 14.72 ft.
