TO RECIPIENTS OF COOPERATIVE SNOW SURVEY 
AND WATER SUPPLY FORECAST REPORTS: 



Forecasts by U. S. Weather Bureau of total annual streamflow October- 
September, inclusive, at more than 300 gaging stations are issued month- 
ly January through May in the publication WATER SUPPLY FORECASTS 
FOR THE WESTERN UNITED STATES. 

Weather Bureau forecasts of runoff presented in this bulletin are com- 
puted from procedures based on mathematical analysis of the relation 
between precipitation and runoff.

WATER SUPPLY OUTLOOK 
COLORADO RIVER DRAINAGE 
FEBRUARY 1, 1953 



Snow accumulation on the headwaters of the Colorado River 
in Colorado, Wyoming and New Mexico is slightly less than 
normal to February 1. The average is about 85 percent of 
normal for the upper basin* Snow melt season runoff is 
expected to be somewhat less than indicated by present 
snow measurements because of deficiency in precipitation 
during the late summer and fall months* Mountain soils 
under the snow are extremely dry* Soil moisture condi- 
tions in valley areas are reported as fair to goods 

Snow cover on principal watersheds of the Arizona tribu- 
taries is much below average and a year ago* Storage on 
the Salt and Verde drainage is much improved over the 
past several years, the highest since 19li2. January tern* 
peratures have been at record highs and precipitation is 
below normal* San Carlos Reservoir on the Gila River is 
near empty a 



COLORADO RIVER AND TRIBUTARIES 
IN COLORADO 

Colorado River (Above Grand Junction) : The snow cover on the Upper Colorado 
River including the Roaring Fork is 87 percent of normal and about one half 
of February 1, 1952. Similar snow conditions exist on other upper Colorado 
River tributaries including the Grand Mesa, At medium elevations the snow 
cover is somewhat less than above 9000 feet and there is practically no snow 
in the foothills » The lack of snow at lower elevations is partially due to 
above seasonal temperatures which has caused mid-winter meltingo Surface 
soil moisture is reported as good but the soil generally is on the dry side* 
Stream flow is about average. Storage in Green Mountain reservoir is now 
108,000 acre-feet as compared to 99,000 a year ago on this date. 

Gunnison River: Snow accumulation to date on the watershed of the Gunnison 
River is similar to the Upper Colorado, at 80 percent of normal* Summer 
stream flow will probably not exceed that indicated by present snow measure- 
ments. Even if the rate of snow accumulation is normal or above for the 
remainder of the season runoff will be materially reduced by dry mountain 
soils o Soil moisture conditions are reported as fair to good in the Gunnison 
and Montrose districts, probably due to snow-melt at valley elevations* 
Stream flow is slightly above normal* Storage in Taylor Park reservoir is 
now 63,900 acre-feet as compared to 53,100 on February 1, 1952 » 

Yampa and White Rivers: Snow on the headwaters of the Green River tributaries 
in Colorado is about 90 percent of normal on February la Summer runoff will 
be adversely affected by the lack of precipitation during the fall months. 
Soil moisture conditions in northwestern Colorado are reported as fair* Stream 
flow is about average >

San Juan and Animas Rivers: Snow cover on the San Juan Mountains is about 
90 percent of normal for February 1 at high elevations and somewhat less at 
lower and valley elevations * Mountain soil moisture is slightly better than 
in other areas of Colorado and much better than a year ago, but probably 
still more deficient in moisture than usual* Precipitation during January 
was about average. Soil moisture conditions at valley elevations are des-» 
cribed as fair to good* Storage in Vallecito reservoir is now 99 » 900 acre- 
feet as compared to 2U,800 on February 1, 1952* 

Dolores River: Snow cover on the Dolores River drainage is similar to the 
San Juan and Animas at 90 percent of normal. Due to warm temperatures in 
January there has been some snow melting at relatively high elevations. Stream 
flow is slightly above average. Soil moisture conditions in the Cortez irri- 
gated district are described as fair. 

COLORADO RIVER TRIBUTARIES 
IN ARIZONA 

Salt River J There is about h inches of water available in less than 2 feet 
of snow in the Mt e Baldy area of the White Mountains. Soil moisture condi- 
tions are still good in this high area, but are beginning to dry. The snow 
is gone for the most part, below 8,000 feet, and these soils are drying* 
Runoff forecast for the flow of the Salt River above Roosevelt for the period 
February through May is 275*000 acre-feet, about 75 percent of normal* 

Verde River: There is little water available in the form of snow even on the 
higher elevations of the Verde River drainage. There is only about 1.5 inches 
of water in 6 inches of snow. Most of this will be lost to sublimation unless 
a warm rain soon brings it off* There is practically no snow below 7,000 
feet. The soil moisture condition is still pretty good, but it is beginning 
to dry. Runoff forecast for the Verde River above Horseshoe for the period 
February through May is 75,000 acre-feet, about 25 percent of normal. 

Gila River: Snow conditions on the Gila River watershed are very poor* There 
is a little snow in the Beaver Head-Coronado Trail area, but most of the rest 
of the drainage is bare* The average is about 0.5 inches of water in 2.3 
inches of snow a There is still good soil moisture in the higher elevations, 
but it is drying. Soil moisture in the lower elevations is poor to fair. 
Runoff forecast for the Gila River above Safford for the period March through 
May is 20,000 acre-feet • 

Williams River Drainage: There is no snow on this drainage, although there 
is still some soil moisture. 

Reservoir storage in the Salt-Verde project at the present time is the best 
it has been in 11 years a The net stored water is over 1,250,000 acre-feet. 
A year ago this date it was 8U3,000 acre-feet. Total capacity is 2,077,000 
acre-feet*
