SURFACE-WATER RECORDS
PERIOD OF RECORD -
SURFACE-WATER DISCHARGE AND STAGE
  DISCHARGE: July 1914 to current. Monthly discharge only for some periods,
    published in WSP 1308.
  STAGE: Water years 1994 to current.
SURFACE-WATER QUALITY
  CHEMICAL: Water years 1978-93.
  SEDIMENT: Water years 1980-97, Feb. 2003 to Sept. 2014.
  MISCELLANEOUS: Sediment concentration and particle size, water years 1993, 1995-97,
    2003-2004.
GAGE - Water-stage recorder, satellite telemeter, sediment sampler, and crest-stage gage. Datum of gage is 466.32 ft above NAVD of 1988. Datum of gage was incorrectly published water years 1927-1941. Prior to May 9, 1935, nonrecording gage 0.5 miles downstream at same datum. May 9, 1935 to June 30, 1976, nonrecording gage 0.47 miles downstream at same datum.
