Prior to February 1946 monthly discharge only, published in WSP 1309.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 1,850.65 ft above NAVD88. Datum was converted to NAVD88 datum using the National Geodetic Surveys VDATUM transformation tool.

June 15 to July 26, 1967, nonrecording gage at site 30 ft upstream and July 27, 1967 to June 14, 1971, water-stage recorder at site 60 ft upstream, both at present datum.
REMARKS - Only discharges above 100 ft³/s published. Accuracy of records for water years prior to 2014 are noted in the individual Annual Data Reports for those water years. For water years 2014 onward, records good except those for Oct. 1, 2014 to Nov. 23, 2015 and those for estimated discharges, which are poor. Satellite data-collection platform at station.
