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.

Annual Values
3-glacier summary
for period of record
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.
