TO RECIP IENTS OF WATER SUPPLY OUTLOOK REPORTS:
Most o f the usable water in western states originates os mountain snowfall. This snowioll accumulates during the winter and
spring, seve ral month s before the snow melts a nd appears as streamflow. Since the runoff from precipitation as snow is delayed,
est imates of snowme lt runoff can be mode well in advance of its occurrence. Streamflow forecasts published in this report are
based p rin c ipa l ly on measurement of the water equiva lent of the mountain snowpock.
Forecasts become more accurate as more of the data affecting runoff are measured. Al l forecasts assume that climat ic
factors d uring the rema inder of the snow accumulation and melt season wil l interact with a resultant average effect on runoff .
Early season forecasts are therefore subjec t to a greater change than those made on later dotes.
The snow course measurement is obtained by sampl i·ng snow depth and water equivalent at surveyed and marked locations in
mountain areas. A tota l of about ten samples are taken at each location. The a verage of these are reported as snow depth and
water equ ivalent. These measurements are repeated in the same location near the same dates each year.
Snow surveys are made monthly or semi -monthly from January 1 through J une 1 in most sta tes. There are about 1900 snow
courses in Western United States and in the Columbia Basin in British Columbia. Networks of automatic snow water equiva lent
a nd rela ted data sensing devices, along w ith rad io te lemetry are expanding and wil l provide a cont·inuous record of snow water
a nd other parameters at key locations.
Detailed data on snow course and soi l moisture measurements are presented in state and local reports. Other data on
reservoir storage , summaries of precipitation, current streamflow, and soi l moisture conditions at valley elevations a re a lso
included . The report for Western United States presents a broad picture of wa ter supply o utlook conditions, including se lected
streamf low forecasts, summary of snpw accumulation to date, and storage in larger reservoirs.
Snow survey a nd so il moisture data for the period of record are published by the Soil Conservation Service by states about
every five years. Data for the current year is summarized in a West - wide basic da ta summary and pub lished about October 1
of each year.

ALASKA SUMMARY
AS OF
February 1, 1982
The southern half of Alaska began the winter with the most early season snowfall
in recent years. By early December, most of southcentral had a far above average
snowpack--but then the weather patterns changed. Very little new moisture fell
during December and January except in the southeast. The Juneau area received a
record amount of new snowfall for the month of January.
Alaska's snowpack now ranges from twice normal to half normal. The east side of
the Talkeetna Range is the maximum for the 18 year period of record. Portions
of the North Slope, Brooks Range, central interior and lower Susitna Valley are
as much as 50 percent below average. In spite of this, all regions of the State
report significantly more snow than last year. Also, well above average percentage wise, are the Kenai Peninsula and portions of the Chugach Ra nge . The
Upper Tanana Valley and the Copper River Basin are slightly above average and
the Yukon River headwaters in Canada are about average. Southeast, although
receiving a great amount of new snow in January, is still below average for
February 1st.

The regional summaries are as follows:
Koyukuk Drainage
Snow courses along the Dalton Highway indicate a snowpack that is only half the
average near Atigun Pass--then gradually increases percentagewise, traveling
south. The Prospect Creek area is slightly below average, while the Thirty Mile
course (thirty miles north of the Yukon crossing) is well above average.
Yukon Drainage
Most of the Canadian Yukon snowcover is about average as reported by the Yukon•s
Department of Indian and Northern Affairs.
Tanana Drainage
The Upper Tanana Valley has an average or better snowcover. The lower Tanana,
by contrast, is well below average. The Fairbanks area and Chena Basin are
about 30 to 40 percent below normal for February lst. The break appears to be
just north of Delta Junction. The entire Tanana Basin, however, has nearly
twice as much snow as this time a year ago.
Copper Drainage
A record breaking snowpack was found along the east side of the Talkeetna
Mountains. The areas drained by the Oshetna (which actually drains north into
the Susitna River) and Little Nelchina Rivers have the heaviest snowcover in
the last 18 years, better than double the normal amount for February lst, and
far ahead of 1972, the next heaviest year. However, such a heavy snowcover
seemed to have a limited extent. The Copper Basin floor was found to be about
10 to 15 percent above average, while snow courses along the Richardson and
Glenn Highways in the Alaska Range were 15 to 20 percent below average.
Susitna Drainage
The upper Susitna Basin is generally 15 to 25 percent below average (except for
the Talkeetna Range -see Copper Drainage above). The Susitna Glacier region
is one of the very few locations in the State reporting less snow than a year
ago.
The lower Susitna Valley has one of the leanest snowpacks in the State, varying
from 15 to 50 percent below normal. The one to two feet of snow is unusually
dense, however, as. no new snow had been deposited since the Thanksgiving storm
which was warm and heavy.
Another notable aspect of the snowpack throughout the Basin was the effect of
an unusual amount of northerly wind. Large drifts, scalloped snow and bare
ridgetops were much more evident than usual. Airplane landings were not
possible at numerous sites as a result.
2
Upper Cook Inlet
' cover slightly below
Snow courses in the Ship Creek Drainage indicate a snow
average (5-10 percent), but considerably more than last year.
A new network of cou~ses has been established on the west side of Cook Inlet.
Known as the Beluga Network, they are located on the Plateau Region between
Trading Bay and Beluga Lake, and are drained by the Chuitna River. They are
called Trading Bay, Congahbuna Lake, Cole Creek, Chuitna Plateau and Capps
Plateau. A Wyoming precipitation gage~ known as Botts Creek is also in place.
They indicate a very lean and heavily wind blown snowcover.
Kenai Peninsula
A fairly heavy snowpack covered the Kenai Peninsula below 2000 feet on
February 1st. Courses along the Seward and Sterling Highways measured 20 to
50 percent above average for their 12 year record period. The pack, below
2000 feet, is also far ahead of last year•s measurements. The deepest reportable snow for the State was measured at Bradley Cirque. The measurement was
more than 14 feet. The Peninsula also is sporting a few new courses for 1982.
Upper Russian Lake, Cooper Lake and Snug Harbor Road are to support the sockeye
salmon fishery of the Russian River, G~ant Creek and Grant Lake (to be read
later) support a hydroelectric power study for Grant Lake, Ski Lake and
Turnagain Pass help support the Seward Highway avalanche control work.
Kodiak Island
The Terror Lake Hydroelectric Project, scheduled for start-up of construction
this summer, has some new courses too. The Falls Creek site, at 2000 feet,
measured nearly 8 feet of depth (probably a modest amount for February 1st for
the site.)
Southeast
Juneau received 72 inches of new snow in January, a record for the month. The
total winters snowcover for February 1st is far from setting records, however.
The snow courses on Douglas Island, opposite Juneau, indicate the low elevation
snowpack is well above average--but tapers off percentagewise rapidly with
increasing elevation. The Cropley Lake course at 1600 feet elevation is about
20 percent below an average of the last 14 years based on a correlation with the
discontinued Douglas Ski Bowl course, whose record began in 1968.
