,) Basinwide Conditions Assessment
The SWSI value 6f -1.1 indicates that for November
the basin water supplies. were below normal. The Natural
Resources Conservation Service reports that December 1
the snowpack was 63% of normal. Flow at the gaging station
Animas. River near Durango was 179 cfs, as ,compared to
the long-term average of 287 cfs. Storage in McPhee,
Vallecito, and Lemon reservoirs totaled 75% of normal as of
the end of November.

Outlook
Novem ber began with a continuation of the dry
weather experienced in September and October. , Many river
flows ,diminished to very/ow b,ase levels. The Animas River
average was only 179 cfsand the la Plata receded to a 5.3
cfs daily flow when 20% more than that would have been
much more typical for a dry condition of flow.
Around Thanksgiving week, a break in the weather
yielded a total of 1.5 inches of moisture for the month. This

was still below the normal of 1.93 inches. TemperatureS
reduced to single digits during the fast week as the dry
snowfall remained on the ground. Reservoirs remained
about the same as last month. Only Vallecito was 'able to
show normal storage amounts for this time of year.

Public Use Imoacts
There was some hope that the weather would
continue the pattern of the last week and the local ski areas
could open with the possibility of an adequate snow
accumulation to carry in to 2002.
