Click to hide 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.

DRAINAGE AREA - 6,500 mi².
REVISIONS HISTORY - WDR AK-98-1, 1987-1997; WDR AK-00-1 1989-90 (M), 1992-95 (M).
PERIOD OF RECORD - July 1987 to current year.
GAGE - Water-stage recorder. Elevation of gage is 50 ft above sea level, from topographic map.
REMARKS - GOES satellite telemetry at station.
EXTREMES FOR PERIOD OF RECORD - Peak of record flow is 137,000 ft³/s at a stage of 45.54 ft. on June 30, 2021. 
PERIOD OF RECORD - Specific Conductance, Water Temperature (YSI), pH, Dissolved Oxygen, fDOM, and Turdidity Water Quality record period begins 05/06/2019
INSTRUMENTATION - Q.W. - A YSI EXO2 Sonde multi-parameter monitor measuring Water Temperature, Specific Conductance, Dissolved Oxygen pH and Turbidity.  The Sonde readings are checked against a calibrated field Sonde and compared to stream cross-section values at each site visit. After readings are compared, the monitoring sonde is either cleaned, calibrated, and replaced in the stream, or swapped with a newly calibrated Sonde.
