'-'V''"'""'""K REPORTS:
Most of the usable water in western states originates as mountain snowfall. This snowrall accumulates during the winter and
spring, several months before the snow melts and appears as streamflow. Since the runoff from precipitation as snow is delayed,
estimates of snowmelt runoff can be made well in advance of its occurrence. Streamflow forecasts published in this report are
based principally on measurement of the water equivalent of the mountain snowpack.
Forecasts become more accurate as more of the data affecting runoff are measured. All forecasts assume that climatic
factors during the remainder of the snow accumulation and melt season will interact with a resultant overage effect on runoff.
Early season forecasts are therefore subject to a greater change than those made on later dates.
The snow course measurement is obtained by sampl i·ng snow depth and water equivalent at surveyed and marked locations in
mountain areas. A total of about ten samples are taken at each location. The average of these are reported as snow depth and
water equivalent. These measurements are repeated in the same location near the same dates each year.
Snow surveys are made monthly or semi -monthly from January I through June I in most states . There are about 1900 snow
courses in Western United States and in the .Columbia Basin in British Columbia. Networks of automatic snow water equivalent
and related data sensing devices, along with radio telemetry are expanding and will provide a continuous record of snow water
and other parameters at key locations.
Detailed data on snow course and soil moisture measurements are presented in state and local reports. Other data on
reservoir storage, summaries of precipitation, current streamflow, and soil moisture conditions at valley elevations are also
included. The report for Western United States presents a broad picture of water supply outlook conditions, including selected
streamflow forecasts, summary of snow accumulation to date, and storage in larger reservoirs .
Snow survey and soil 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 data summary and published about October 1
of each year.

SPRINGTIME ON KODIAK ISLAND
ALASKA SUMMARY
ASOF
May 1,1984
OVERVIEW
Snowfall during April was well below average over most of the state. A few
areas were just the opposite. Above average snow fell on the Kenai
Peninsula, Kodiak Island, Western Chugach Range, and a portion of the
central interior, including Fairbanks.
The winter's snowcover is now average or better on only a small portion of
the state. Most of this area is south of the Alaska Range, and within the
Copper Basin and Upper Cook Inlet watersheds. North of the Alaska Range,
only an area of the central interior, north of the Yukon River , has average
or better snow for May 1st.
Nearly the entire western half of the state, the North Slope and much of
Southeast, has a far below average snowcover. The central and eastern
interior, south of the Yukon River, is a little below average, overall.
A much cooler than normal April has significantly delayed the onset of the
breakup season. A late breakup season has caused the National Weather
Service to raise their rating of this year's ice jam flood hazard to
moderate-high on the Yukon and Kuskokwim Rivers.
UPPER YUKON DRAINAGE
Much of the Canadian headwaters of the Yukon River experienced a fairly dry
April. Little snow fell in the southwest portion of the Yukon Territory,
while areas to the north and east varied up to near normal for the month.
Most of the Upper Yukon has a lean snowcover. Exceptions are the Stewart
and Pelly River drainages upstream of Dawson, and the Chandalar River in
northeast Alaska. Snow in these areas is generally average or better.
TANANA DRAINAGE
New snowfall during April was divided within the basin between the northwest
or downstream half, which received well above average, and the southeast or
upstream half, where precipitation fell off to almost nothing at the
Canadian border. The snowcover was all but gone in valley bottoms by May
1st. Snowfall was below average in the Chena Basin, but snowmelt was also
deficient so the snowpack is higher, percentagewise, than a month ago.
KOYUKUK DRAINAGE
The Koyukuk River Headwaters was one of the few regions north of the Alaska
Range to show an increase in the snowpack during April. Precipitation at
Bettles was 27 percent above average for the month. Snow courses along the
Dalton Highway measured a net increase of 0.5 inches of water-content.
Normally, they lose several inches of water during April. The result is
that the snowpack is now above average, compared to being below average a
month ago.
COPPER DRAINAGE
The Copper Drainage generally received well below average precipitation for
the month. Cooler than normal temperatures, however, produced little
snowmelt. The snowpack here also has increased, percentagewise, compared to
a month ago. The remaining snowcover is generally a little above average
everywhere, but the west side which has been 20 to 30 percent or more below
average all winter.
SUSITNA DRAINAGE
Overall, snow in the Upper Susitna Basin is about average for May 1st. The
Alaska Range is still above average, while the Talkeetna Tributaries are
well below average. The Upper Susitna Basin received less than normal
snowfall during April.
Snow in the Lower Susitna Valley normally exhibits a net decrease in
water-content during April with the onset of the breakup season. Cooler
than normal temperatures, however, produced less melt than usual, so the
remaining pack is now very heavy for May 1st.
2
UPPER COOK INLET
The mountains east of Anchorage were the target area for several snow storms
during the month. The Indian Pass course received over 6 inches of new
moisture, more than double its normal monthly increment. The forecast of
snowmelt runoff from Ship Creek, which supplies Anchorage with close to half
its municipal water supply, made a 25 percent jump from the April forecast.
Ship Creek is now expected to produce 66,000 acre-feet of water through
July. This is six percent more than average and significantly reduces but
does not eliminate the annual summer threat of a water shortage in Anchorage.
The west side of Cook Inlet in contrast to the east, received well below
average precipitation for the month .
KENAI PENINSULA
Heavy spring snow storms hit the southern end of the Kenai Peninsula. They
mainly affected the Kachemak Bay area and Kenai Mountains, north at least to
Seward. The storms did not greatly affect the west side of the Peninsula or
the northern end of the mountains.
The snowcover throughout the Peninsula remains below normal. Snowmelt
runoff from the northern Kenai mountains may be as much as 25 percent below
average.
PRINCE WILLIAM SOUND
Mountains surrounding the Sound received a below normal to near normal
increment of new snow during April . The snowcover near Thompson Pass, along
the Richardson Highway, is now slightly below average for the winter.
KODIAK ISLAND
Storms tracking across the Gulf of Alaska have kept Kodiak one of the
wettest spots in the state, percentagewise. April followed the winter-long
trend. The whole winter's precipitation at Kodiak is now SO percent more
than the 34 year average. However, it is only 16 percent above the average
since 1973.
Snow in the mountains fell at a lower rate, percentagewise, this year than
at lower elevations. Also, considerable snowmelt occurred during November
and December when temperatures were well above normal. The result is that
the snowpack at the Falls Creek course, near Terror Lake at 2000 elevation,
is slightly below the estimated average pack for the site. The snowpack,
however, represents only 65 percent of the estimated moisture to have fallen
at Falls Creek . Therefore, a fairly heavy snowpack exists at higher
elevations . Inflow into the Terror Lake reservoir is estimated to be 79,000
acre-feet for the May through August snowmelt period . The forecast is 12
percent above average and is based on precipitation-to-come being normal.
3
SOUTHEAST
The snowpack is gone from the lower elevations of the southeast region. The
Speel River snow course, southeast of Juneau, which normally has over five
feet of snow and 29 inches of water-content on May 1st, had only six inches
of snow depth. The Speel River course has been measured for 20 years, and
never before had less than two feet on this date.
The higher elevation snowpack may not be as deficient, however. Several
courses indicate a snowpack of only 10 to 20 percent below average above
1500 feet elevation .
