USGS Water-Year Summary 2025

07263500 ARKANSAS RIVER AT LITTLE ROCK, AR

LOCATION - Lat 34°44'57.59", long 92°16'00.12" 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,

As of June 2025, the gage was relocated to the downstream side of the first pier from the right bank on the Junction Bridge at river mile 165.6. It is positioned on the handrail inside of the equipment enclosure, accessed via the gate behind the elevator.

Prior to June 2025, the gage was situated on top of the second pier from the right bank of the Main Street Bridge, 0.25 miles above the Missouri Pacific Railway bridge at Little Rock, at river mile 165.5.

DRAINAGE AREA - 158,000 mi² of which 22,000 mi² probably is noncontributing.

REVISIONS HISTORY -

Prior to June 2026, the gage was located on the Main Street Bridge at river mile 165.5. After June 2025, the gage was relocated downstream 0.1mi to the Junction Bridge (Lat 34°44'57.59", long 92°16'00.12") at river mile 165.6.

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.

GAGE -

The gage datum is 223.33 ft above NAVD88 (Reference Frame NAD_83 (2011) (EPOCH:2010.0000), (GEOID18).

Prior to October 2024, the datum of the gage was 223.61 ft above NGVD 29.

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.
