Streamflow/Runoff Data From Phelan Creek near Paxson, Gulkana Glacier, Alaska

Description

The "Phelan Creek near Paxson" stream-gaging station, USGS station 15478040, is part of the USGS network of nearly 100 stations in Alaska. Data collection and analysis are conducted by standard techniques developed by the USGS. Daily values of discharge are generally reported along with those for the rest of Alaska in annual publications of the USGS Water-Data Report series, and available on-line (see links below).

LOCATION: Lat 63°14'27"N., Long 145°28'03"W., 1,125 m altitude, in SW 1/4 sec.28, T.19 S., R.12 E., Hydrologic Unit 19020102, on left bank about 1 km downstream from terminus of Gulkana Glacier and 23 km north of Paxson, Alaska.

DRAINAGE AREA: 32 km² .

PERIOD OF RECORD: October 1966 to September 1978, October 1989 to September 1993, October 1994 to current year, and annual maximums, water years 1984-85. Before October 1968, published as Gulkana Creek near Paxson.

NOTE: Records are poor. The creek bed is composed of typical ground-moraine material: poorly-sorted gravel and small boulders. The channel is subject to frequent changes during high flows. Large fluctuations result from ice melt and alternate damming and storage release during melt season. Typical winter under-ice discharge is about 0.1 m³/s; typical summer discharge is about 4-20 m³/s; the period-of-record peak discharge is 65 m³/s (Linn and others, 1994). The typical minimum winter under-ice discharge is about 0.04 m³/s, which is about three to four times the average contribution from the combined geothermal melt of the bed of the glacier and melting caused by the loss of potential energy from ice motion.
