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 will interact with a resultant average 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 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 1900 snow 
courses in Western United States and in the Columbis 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 of 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. 



PUBLISHED BY SOIL CONSERVATION SERVICE 

The Soil Conservation Service publishes reports following the principal snow survey dates from January 1 through June 1 in 
cooperation with state water administrators, agricultural experiment stations and others. Copies of the reports for Western 
United States and all state reports may be obtained from Soil Conservation Service, Western Regional Technical Service Center,

WATER SUPPLY OUTLOOK 

as of 

April 1, 1971 




The map on this page indicates the most probable water supply as of the date of this report. Estimates 
assume average conditions of snow fall, precipitation and other factors from this date to the end of the fore- 
cast period. As the season progresses accuracy of estimates improve. In addition to expected streamflow 
reservoir storage, soil moisture in irrigated areas, and other factors are considered in estimating water supply 
Estimates apply to irrigated areas along the main streams and may not indicate conditions on small tributaries 



WATER SUPPLY CONDITIONS 

as of 

April 1, 1971 

WATER SUPPLIES WILL VARY GREATLY OVER COLORADO AND NEW MEXICO THIS 
SUMMER. NORTHERN COLORADO SHOULD HAVE EXCELLENT WATER SUPPLIES. FORECASTS 
ARE 100 TO 130% OF NORMAL. THE MIDDLE AREAS OF COLORADO, THE ARKANSAS, THE 
COLORADO AND THE GUNNISON RIVERS SHOULD HAVE NEAR NORMAL WATER. THE SOUTHERN 
PORTION OF COLORADO AND NORTHERN AND CENTRAL NEW MEXICO HAVE VERY POOR WATER 
PROSPECTS. COLORADO HAS GOOD TO FAIR CARRY-OVER STORAGE. SOILS IN THE 
IRRIGATED AREAS OF NEW MEXICO ARE REPORTEDLY IN POOR CONDITION. COLORADO 
REPORTS GOOD CONDITIONS. 



~ THE SNOW PACK IN NORTHERN COLORADO IS EXCELLENT. SOME 
COLORADO 



SNOW COURSES ARE THE MAXIMUM OF RECORD. BOTH THE EAST AND WEST 
SLOPES OF NORTHERN COLORADO SHOULD ENJOY ONE OF THE BEST WATER YEARS ON RECORD. 
THE COLORADO RIVER SHOULD SUPPLY ADEQUATE WATER TO ALL ITS USERS. GENERALLY 
THE ARKANSAS AND GUNNISON RIVERS SHOULD PRODUCE NEAR NORMAL WATER SUPPLIES. 
THE SOUTHERN PORTION OF THE STATE, THE RIO GRANDE AND THE SAN JUAN BASINS, CAN 
PLAN ON A DRY SUMMER. UNLESS SUMMER RAINS ARE PLENTIFUL, WATER SHORTAGES WILL 
OCCUR. CARRY-OVER STORAGE IS GOOD ESPECIALLY IN THE SOUTH PLATTE BASIN. 

^ McvA/ ..nrv.^^ ~ WATER SUPPLIES THIS SUMMER COULD BE AMONG THE LOWEST 
/^^\ NEW MEXICO 



ON RECORD. PRACTICALLY NO SNOW IS LEFT IN NEW MEXICO. NEW 
MEXICO STREAMS ORIGINATING IN COLORADO WILL HAVE A POOR START. ALL FORECASTS 
ARE WELL BELOW NORMAL. RESERVOIR CARRY-OVER STORAGE IS NEAR NORMAL. UNITS 
WITH DIRECT FLOW RIGHTS ON NEW MEXICO'S MAJOR STREAMS, AND NO STORAGE WILL HAVE 
A PARTICULARLY POOR YEAR. THE FLOW PEAKS WILL BE LOW AND LAST ONLY A SHORT 
PERIOD. LATER SUMMER FLOW WILL BE REDUCED UNLESS SUMMER RAINS ARE BOUNTIFUL.

WATER USERS ON THE UPPER SOUTtl PLATTE AND ALL THE NORTHERN TRIBUTARIES 
SHOULD HAVE ONE OF THE BEST WATER YEARS ON RECORD. ALL STREAMFLOWS ARE BEING 
FORECASTED ABOVE NORMAL. CARRY-OVER STORAGE IN THE AREA'S MANY RESERVOIRS IS 
136% OF THE 15 YEAR AVERAGE. THIS WILL PROVIDE AN EXCELLENT SUPPLEMENTAL 
SUPPLY. IRRIGATION AUTHORITIES INDICATE VALLEY SOILS ARE IN EXCELLENT
