GAGE - Water-stage recorder, satellite telemeter, water-quality monitor, and crest-stage gage. Datum of gage is 503.74 ft above NGVD of 1929 (503.59 ft NAVD 1988) from Aug. 30, 1982 to present. However, datum incorrectly published as 503.33 ft above NGVD of 1929 from Aug. 30, 1982 to Sept. 30, 2001. Prior to Jan. 9, 1935, nonrecording gage at same site and datum 503.33 ft above NGVD of 1929 (levels by U.S. Army Corps of Engineers) (503.18 ft NAVD 1988). However, datum incorrectly published as 503.99 ft above NGVD of 1929 from 1928 to 1943. Jan. 9, 1935, to Aug. 30, 1982, at site 0.3 mi downstream and datum 503.33 ft above NGVD of 1929 (503.18 ft NAVD 1988).
REMARKS - Effluent from sewage-treatment plant 0.5 downstream from gage is included in discharge records. Flow regulated at times by storage at Lake Vermilion on North Fork Vermilion River, 4.5 mi upstream from station, usable capacity, 7,440 acre-ft, and by Danville sewage-treatment plant. Accuracy of records is discussed in the annual Station Analysis archived at the USGS IL Water Science Center.
