DEPARTMENT OF AGRICULTURE Cooperating with ALASKA SOIL CONSERVATION DISTRICT r---ASOf -......, FEB. 1, 1982 TO RECIPIENTS OF WATER SUPPLY OUTLOOK REPORTS: Most of t he usable water in western states originates os mountain snowfall. This snowral l accumulates during th,e winter and spring, several month s before the snow melts and appears as streamflow. Since the runoff from precipitatipn as snow is delayed, estimates of snowme l t runoff can be mode well in advance of its occurrence. Streamflow forecasts published in t his report are based principally on measurement of the water equiva l ent of the mountain snowpack. Forecasts become more accurate as more of the data affec t ing runoff are measured. Al l forecasts assume tha t climat i c factors d uring the remainder of the snow accumulation and melt season wil l interact with a resultant average effect on runoff . Earl y season forecasts are therefore subject to a greater c hange t ha n those mode 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 ore token at each location. The o verage of these ore reported as snow depth and water equivalent . These measurements are repeated i n t he same location near the same dates each year. Snow su rveys ore made monthly or semi -monthly from January 1 through J une 1 in most sta tes. There ore about 1900 snow courses in Western United States and in the Co lumbia Basin i n British Columbia. Networks of automatic snow water equiva le nt and re la t ed data sensing devices, along w ith rad io te l emetry are expanding and wil l provide a continuous record of snow water and other parameters at key locations. Detailed data on snow course and soi l moisture measurements ore presented in state and local reports. Other data on reservoir storage, summaries of precipitation, current streamflow, and soi l moisture conditions at valley elevations are also included . The report for Western United States presents a broad picture of water supply outlook conditions, including se lected streamflow forecasts, summary of snow accumulation to date, and sto rage in larger reservoi rs. Snow su r vey a nd soil moistu re data for the period of record are published by the Soil Conservation Serv ice by states about every five years. Data for the current year is summarized in a West -wide basic da ta summary and pub li shed about October 1 of each year.

AT GIRDWOOD FOR AVALANCHE CONTROL WORK 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. I n spite of this, all regions of the State report significantly more snow than last year. Also, well above average per- centage wise, are the Kenai Peninsula and portions of the Chugach Range . 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. ~ 0 N 0 N ' ~ I ~ :> 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 1st. 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 Mn. ....... +o~;........

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 Snow courses in the Ship Creek Drainage indicate a snow cover slightly below average (5-10 percent), but considerably more than last year. A new network of cour.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 report- able 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, Grant 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. 3 REGION TANANA COPPER RIVER MATANUSKA/SUSITNA COOK INLET KENAI PENINSULA KODIAK ISLAND NEW COURSES FOR 1982 (Measured February 1st) COURSE ELEV.
