1. Operational Plan:

a. Statement of the Nature and Objective of Proposed Project.

The nature of the proposed program is to augment natural precipitation

within the project area to provide improved snowpacks and additional

water supplies for storage and beneficial use. The operational

technology and procedures utilized in this program were derived

from previous snowpack augmentaion programs operated in Colorado,

specifically: the Climax and Wolf Creek research programs, the

Colorado River Basin Pilot Project and the last ten winters' programs

operated by WESTERN WEATHER CONSULTANTS, INC. in the Central Colorado

and San Juan Mountains.

The objectives of the project are to increase snowpacks in the

drainage basins of all major mountain massifs in the project area

which should result in increased run-off into the storage systems in

these basins and result in an additional water supply for agricultural,

industrial or domestic use along with an additional snowpack for

winter recreational use.

b. A written description of the target area and the area reasonably

expected to be affected by the proJect. See attached map.

The target area consists of the Animas River drainage from the

headwaters down to approximately the Trimble area below Hermosa; the

headwaters of the La Plata River down to Mayday; the headwaters of the

Mancos River above Jackson Reservoir and the headwaters of the Dolores

River down to the Stoner area. (See attached map).

The area reasonably expected to be affected by the project are

those ridges and areas on the windward side (as per the relative location

with respect to the generator locations) downwind of the generator

sides at approximate elevations above 9,500' MSL in the target area and

the uppermost downwind ridge areas beyond the target area. (See attached map).
