TO RECIPIENTS OF WATER SUPPLY OUTLOOK REPORTS: 


Most of the usable water in western states originates as mountain snowfall. This snowfall 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 as they affect runoff will add to be an effective average. 
Early season forecasts are therefore subject to a greater change than those made on later dates. 

The snow course measurement is obtained by sampling 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 1 through June 1 in most states. There are about 1400 snow 
courses in Western United States and in the Columbia Basin in British Columbia. In the near future, it is anticipated that 
automatic snow water equivalent sensing devices along with radio telemetry will provide a continuous record of snow water 
equivalent at key locations. 

Detailed data on snow course and soil moisture measurements are presented in state and local reports. Other data or 
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 . 

Listed below are water supply outlook reports based on Federal -State -Private Cooperative snow surveys. Those published 
by the Soil Conservation Service may be obtained from Soil Conservation Service, Room 507, Federal Building, 701 N. W. 
Glisan, Portland, Oregon 97209.

WATER SUPPLY OUTLOOK 


State of Washington 
March 1 , 1967 

a^- 

* The water supply outlook for irrigation and power in the Columbia * 

* portion in Washington and tributary streams can still be consider- * 

* ed very good for this time of year. Snow surveys made near the * 

* first of March indicate a snowpack that is generally close to aver- * 

* age. Minor exceptions to this are the Kettle River at 33% above * 

* normal. Mill Creek 39% below normal and the Cedar River 32% below * 

* normal. The continuation of above normal temperatures and below * 

* normal precipitation was felt throughout the whole State with all * 

* drainage divisions reporting sub-normal precipitation, Runoff * 

* was generally below normal with the exception of the Palouse and * 

* Walla Walla Rivers which experienced near record low flows during * 

* the month of February. The snowpack in the State as was reported * 

* last' month is good to excellent above the 4500 foot elevation and * 

* poor to nonexistent below this elevation. Since most of the snow * 

* courses are to be found in this higher elevation belt the snow- * 

* pack indicates normal or above normal snow cover. Water from this * 

* high elevation snowpack will be the sustaining factor during the * 

* latter part of the irrigation season. Water from the lower ele- * 

* vation snowpacks are generally considered "flashy" and unreliable * 

* for water supply purposes. The soil mantles continue to be wet up * 

* over those reported last month mainly because the soil moisture * 

* stations are in the lower elevations. Most reservoirs have less * 

* than normal amounts of water in storage for March 1 but with the * 

* adequate forecasted runoff they should comfortably fill during * 

* the runoff season. Comparing March 1 results with last month, * 

* the overall situation is about the same and with normal condi- * 

■* tions, subsequent to this date, no shortages of water should * 

* occur. * 

/'in bjLo f'jn 

SNOW COVER 

If we had a complete picture of the snow cover as it occurred through- 
out the Northwest we would see that in the northern portion of the 
basin in British Columbia record snowpacks were measured at all high 
elevation snow courses and above normal snowpacks at the rest. As a 
person looks further to the south the higher elevation snowpacks con- 
tinue to be good"-not the records of Canada but still above normal and 
the lower elevation snowpacks completely disappear. This condition 
continues through Washington and on into Oregon with a lessening of 
the snowpack at higher elevations and drier soils at the lower eleva- 
tions. The individual stations in Washington indicate the snow cover 
to be from 177o above normal to 39% below. Most of the watersheds have 
normal or near normal snow covers as of March 1. The Puget Sound 
drainage has an enormous variance from the 17% above normal to 32% 
below. The 0l3nnpic Peninsula courses indicate near normal conditions 
in all areas.

RESERVOIRS 

With the exception of Ross and Diablo reservoirs in the Puget Sound 
drainage and Banks Lake in the Columbia Basin, all reservoirs, both 
power and irrigation, have less water in storage than normal for this 
time of year. It is assumed that the lack of February precipitation 
has accounted for this decided drop in reservoir storage over that 
which was reported last month. The major irrigation reservoirs in the 
Yakima basin have 704,600 acre=feet of storage as of March 1 compared 
to 531,800 for last year at this time. Inflow to these reservoirs was 
over three times as great this past month as occurred last year at 
this time. These reservoirs should all completely fill with the spring 
runoff, even Rimrock Lake which sometimes falls short of the expected. 

PRECIPITATION 

All drainage divisions reported by the United States Weather Bureau 
for the month of February showed far less than normal rainfall. De- 
cember and January precipitation for these same drainage divisions was 
generally above normal. The excessive departures on the minus side 
this past month have completely eliminated the surplus total for the 
northeast, southeast and central portions of the State. The winter 
total for the other drainage areas still is on the positive side but 
has been depleted by the lack of February precipitation. 

SOIL MOISTURE 

In the central portion of the State the soil mantle is wetted to well 
above that which occurred in 1965, In the Okanogan drainage the situ- 
ation is similar to last year but not as good as the year before. The 
Yakima area is similar to both 1966 and 1965. In the southeastern 
portion soils are wetted to well above last year at this time but 
still well below that which occurred in 1965. The soil moisture sta- 
tions in Oregon, adjacent to Washington, indicate the soil mantle to be 
827o of capacity but only 77% of last year. The lack of precipitation 
and high temperatures have accounted for most of this increase where 
noted. Snow that melts first enters the soil mantle before it can run 
off. 

STREAMFLOW 

During the month of February near record low flows occurred in the 
Walla Walla River and the Palouse River in southeastern Washington. 
Over the remaining portion of the State river flows were normal to 
slightly below. Forecasts of streamflows indicate the expected runoff 
from the stations in Washington and tributary areas will vary from 25% 
above normal to 27% below normal. The flow of the main stem of the 
Columbia River as measured at The Dalles has decreased slightly over 
that which was reported last month due to lack of increased snow in 
the Snake River portion of the basin as well as the lack of precipita- 
tion over the basin as a whole. Numerical forecasts can be found 
elsewhere in this report.

STREAMFLOW FORECASTS - MARCH 1967 


The following summarized runoff forecasts are based principally on mountain 
snow cover and on the assumption that precipitation and temperature will be 
near average from the present time to the end of the forecast period. Appre- 
ciable deviations from normal of tem.perature and/or precipitation will corre- 
spondingly modify these forecasts .
