Click to hide Water-Year 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 2023
07263500 ARKANSAS RIVER AT LITTLE ROCK, AR
LOCATION - Lat 34°44'59", long 92°16'09" referenced to North American Datum of 1983, in SW 1/4 NW 1/4 sec.03, T.1 N., R.12 N., Pulaski County, AR, Hydrologic Unit 11110207, on top of the second pier from the right bank of the Main Street Bridge, 0.25 mile above Missouri Pacific Railway bridge at Little Rock, and at river mile 165.5.
DRAINAGE AREA - 158,000 mi² of which 22,000 mi² probably is noncontributing.
SURFACE-WATER RECORDS
PERIOD OF RECORD - Oct 1927 to Sep 1969, operated as a continuous-record gaging station. Oct 1969 to current year, operated as a stage-only station.
REMARKS - As the number of streams on which streamflow information is likely to be desired far exceeds the number of continuous-record stream-gaging stations feasible to operate at one time, the USGS collects limited streamflow data at sites other than the continuous-record stream-gaging stations. When limited gage-height data are collected on a systematic basis over a period of years for use in hydrologic analyses, the site at which the data are collected is called a stage-only station. Data collected at these stations are usable in low-flow or floodflow analyses, depending on the type of data collected. The following table contains the annual maximum stage for this stage-only station. No discharge measurements are made at stage-only stations. Only the maximum gage-height for the water year is given. The years given in the period of record represent water years for which the annual maximum has been determined.
