Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
USGS Water-Year Summary 2024
02237700 APOPKA-BEAUCLAIR CANAL NEAR ASTATULA, FL
LOCATION - Lat 28°43'20", long 81°41'06" referenced to North American Datum of 1927, in NW 1/4 sec.26, T.20 S., R.26 E., Lake County, FL, Hydrologic Unit 03080102, near left bank 80 ft upstream from lock and dam, 500 ft upstream from bridge on County Road 48, and 3.0 mi east of Astatula.
DRAINAGE AREA - 184 mi².
REVISIONS HISTORY - WSP 1905: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - July 1942 to June 1948 (discharge measurements only at site 1.5 mi downstream), July 1958 to current year.
GAGE - Water-stage recorder, gate-opening recorder, and data-collection platform. Datum of gage is at NGVD of 1929 and 1.08 ft below NAVD of 1988. Prior to June 1948, nonrecording gage at site 1.5 mi downstream at datum 60.68 ft higher. March to June 1958, nonrecording gage at present site and datum. Since July 1958, auxiliary water-stage recorder at downstream side of lock and dam at same datum.
COOPERATION - Gate-opening record provided by St. Johns River Water Management District.
REMARKS - Since May 1956, flow regulated at station by manipulation of gates in spillway. Discharge computed from relation between discharge, head, and gate openings. Starting March 2, 2009, flow regulated by Nutrient Reduction Facility (NURF) which bypasses the lock and dam structure. Discharge is computed by the index velocity and stage in the NURF outlet channel and added to any structure discharge.
