WATER SUPPLY OUTLOOK

STATE ENGINEER of COLORADO
and STATE ENGINEER of NEW MEXICO
Data included in this report were obtained by the agencies
named above in cooperation with the Bureau of Reclamation,
U.S. Forest Service, National Park Service, Corps of Engin-
eers and other Federal, State and private organizations.
AS OFI
MAR. 1, 1972
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 interuct 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 fiom January 1 through June 1 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 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 val ley 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 .

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
March 1, 1972
SNOWFALL DURING FABRUARY WAS BELOW NORMAL IN ALL AREAS. HOWEVER, MOST OF
COLORADO AND NEW MEXICO STILL HAVE NEAR NORMAL SNOWPACK WITH THE EXCEPTION OF
THE RIO CHAMA AND SAN JUAN BASINS. THE UPPER COLORADO AND THE SOUTH PLATTE
BASINS HAVE THE HIGHEST SNOWPACKS. LOW SNOWFALL AND WARM TEMPERATURES HAVE
CAUSED MELTING ON SOUTH FACING SLOPES, ESPECIALLY IN SOUTHERN COLORADO AND
NEW MEXICO. RESERVOIR STORAGE IS GOOD IN NORTHERN COLORADO AND POOR ON THE
ARKANSAS IN COLORADO AND RIO GRANDE IN NEW MEXICO.
— FEBRUARY SNOWFALL WAS LESS THAN NORMAL OVER THE ENTIRE
L^colorado STATE AND MUCH LESS THAN NORMAL IN THE SOUTHERN PORTION.
(y MOST AREAS STILL SHOW ABOUT NORMAL SNOWPACK, BUT PERCENTAGE-WISE
' LESS THAN LAST YEAR. STREAMFLOW FORECASTS RANGE FROM 75 TO 110 PERCENT OF THE
1953-67 AVERAGE. RESERVOIR STORAGE IS ABOVE NORMAL IN ALL AREAS EXCEPT THE
ARKANSAS DRAINAGE. THERE STORAGE IS ABOUT 71% OF THE 15 YEAR AVERAGE. SOIL
MOISTURE CONDITIONS ARE REPORTED AS FAIR IN THE IRRIGATED AREAS OF THE STATE
AND MOUNTAIN SOILS CONTAIN NEAR NORMAL MOISTURE. MORE SNOW IS NEEDED.
— WEATHER IN NEW MEXICO DURING FEBRUARY WAS WARM AND
/^k new mexico DRY. THIS DID NOT IMPROVE THE MOUNTAIN SNOWPACK.
ALL STREAMFLOW FORECASTS WERE REDUCED DUE TO THE BELOW NORMAL
SNOWPACK. FORECASTS RANGE FROM 85% OF NORMAL ON COSTILLA CREEK TO ABOUT NORMAL
ON RIO HONDO. THE SAN JUAN INFLOW TO NAVAJO IS ABOUT NORMAL, BUT CONSIDERABLY
REDUCED FROM LAST MONTH. FLOW OF THE PECOS SHOULD BE BELOW NORMAL. RESERVOIR
CARRY-OVER STORAGE IS POOR, BUT WILL PROVIDE SOME SUPPLEMENTAL SUPPLIES.
CONSIDERABLY MORE SNOW IS NEEDED TO INSURE ADEQUATE WATER THIS SUMMER.

THE MOUNTAIN SNOWPACK DROPPED TO NORMAL OR SLIGHTLY BELOW DUE TO THE BELOW
AVERAGE SNOWFALL DURING FEBRUARY. STREAMFLOW FORECASTS ALSO WERE REDUCED.
THE GUNNISON SHOULD FLOW ABOUT NORMAL IF SNOWFALL IS AT LEAST NORMAL FOR THE
REMAINDER OF THE YEAR. SURFACE CREEK SHOULD FLOW JUST ABOVE NORMAL AND THE
UNCOMPAHGRE SLIGHTLY BELOW. BLUE MESA RESERVOIR CONTAINS 323,000 A.F. WHICH
IS 77% OF LAST YEAR. MOUNTAIN SOIL MOISTURE IS BETTER THAN NORMAL.
