USGS Water-Year Summary 2019
02313100 RAINBOW RIVER AT DUNNELLON, FL
LOCATION - Lat 29°02'57", long 82°26'52" referenced to North American Datum of 1927, in NW 1/4 sec.36, T.16 S., R.18 E., Marion County, FL, Hydrologic Unit 03100208, at bridge on State Highway 484, 5.0 mi downstream of Rainbow Springs head, 1 mi east of Dunnellon, and 0.9 mi upstream from mouth.
DRAINAGE AREA - Indeterminate.
SURFACE-WATER RECORDS
PERIOD OF RECORD - 1899, 1905, 1907, 1917, 1929-30 (one discharge measurement each water year), October 1930 to November 1964 (discharge measurements only made at various intervals from monthly, bi-monthly, or quarterly), January 1965 to current year. Prior to October 1940, published as "Blue Springs near Dunnellon". October 1940 to September 2007, published as "Rainbow Springs near Dunnellon".
GAGE -

Water-stage recorder, acoustic-velocity meter, and data-collection platform. Gage at CR 484 highway bridge established March 10, 2005. Datum of gage is 23.47 ft above North American Vertical Datum of 1988. Prior to March 22, 2018, datum of gage was 24.42 ft above National Geodetic Vertical Datum of 1929. Continuous discharges for this station have always been determined from discharge measurements made 0.25 mi upstream of CR 484 bridge although record published prior to September 2007 referenced 02313092 and 290514082270701 both of which are at a different datum from the current bridge site datum. 

COOPERATION - This gage is monitored in cooperation with the Southwest Florida Water Management District.
REMARKS - Discharge measurements made approximately 0.25 mi upstream from bridge on State Highway 484 and about 5 mi downstream from head of springs; surface inflow between springs and measuring site is negligible except after heavy rains. Discharge computed from relation between water elevation at Rainbow Springs well (290514082270701) and discharge at measuring site.
WATER-QUALITY RECORDS
PERIOD OF RECORD - October 2015 to current year.
COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
INSTRUMENTATION - Water quality-monitor consisting of a nitrate sensor.
EXTREMES FOR PERIOD OF RECORD - NITRATE: Maximum, 1.85 mg/l, Jan. 02, 2018; minimum, 1.25 mg/l, Sept. 03, 2016.
