PERIOD OF RECORD - Aug. 1924 to Sept. 1925, Dec. 1947 to Sept. 1985 (daily mean discharge). Oct. 1985 to Sept. 2005 (peaks above base discharge), Oct. 2005 to current year. Prior to 1968, published as "Nolands River at Blum". PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Jan. 1962 to Aug. 1981, Feb. 1999 to Aug. 2004. BIOCHEMICAL DATA: Jan. 1962 to Aug. 2004. PESTICIDE DATA: Aug. 1970 to June 1972. RADIOCHEMICAL DATA: Apr. to June 1981, Feb. 1999 to Aug. 2004.

GAGE - Water-stage recorder. Datum of gage is 551.48 ft above NGVD of 1929, 551.60 ft above NAVD of 1988. July 29, 1924, to Sept. 30, 1925, and Nov. 14, 1947, to May 28, 1949, nonrecording gage at railway bridge (now abandoned) 0.5 mi upstream at datum 5.00 ft higher.
