USGS Water-Year Summary 2024

02310750 CRYSTAL RIVER NEAR CRYSTAL RIVER FL

LOCATION - Lat 28°54'17.09", long 82°38'07.31" referenced to North American Datum of 1927, in sec.13, T.18 S., R.16 E., Citrus County, FL, Hydrologic Unit 03100207, at left bank, 0.1 mi downstream from confluence of salt and Crystal Rivers, 2.7 miles west of town of Crystal River, and 4.0 mi upstream from mouth.

DRAINAGE AREA - unknown

SURFACE-WATER RECORDS

PERIOD OF RECORD -

February 1964 to September 1977; October 1977 to October 1989 (gage height only), discontinued. December 2020 to current year.

GAGE - Water-stage and velocity recorder. Datum of gage is North American Vertical Datum of 1988. Prior to December 2020, datum of gage was 0.90 feet lower at National Geodetic Vertical Datum of 1929 and prior to October 1977 datum of gage was 10.90 feet lower. Prior to March 1987, at site 0.2 mi upstream.

COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.

REMARKS - Streamflow at this site is significantly affected by astronomical tides. The residual discharges are not total "freshwater" flow, but are a combination of freshwater flow and water storage caused by higher or lower Gulf of Mexico mean water levels. By convention, the U.S. Geological Survey has established ebb (seaward) flows as positive flow and flood (landward) flows as negative flows.

EXTREMES FOR PERIOD OF RECORD - Maximum elevation, 7.00 ft., Aug. 30, 2023; minimum, -3.62 ft., Sept. 9, 1965.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Temperature and specific conductance, November 2020 to current year.

INSTRUMENTATION - Water-quality monitor consisting of temperature and specific conductance sensors.

EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE: Maximum, 40,500 microsiemens, Nov. 11, 2022; minimum, 1360 microsiemens, Dec. 14, 2021. TEMPERATURE: Maximum, 33.5 °C, Aug. 14, 2023; minimum, 10.6 °C, Dec. 27, 2022.
