Non-Reimbursable Project Investment Application -CWCB Construction Fund
• Form Revised April 2010
5. Explain why you are requesting a grant,instead of a loan. (the Construction Fund exists primarily to
provide low interest loans for the construction or rehabilitation of raw water projects. Non-
reimbursable investments are approved only when the project or study is of statewide interest and
benefits a wide range of people and organizations, and/or a large geographical area.
The CWCB funding leverages out of state funding with a goal of modernizing traditional seeding methods
deployed for the last 40 years in Colorado.This is building on successes from the field and other states.Another
new remote generator will be deployed on the Grand Mesa winter 2012-13 paid for by the Lower Basin and
CWCB. Remote generators are used almost exclusively in NV,CA,ID,WY.Results from Australia and
Wyoming research projects have documented their efficacy. With warming climates and the price of silver
iodide propane seeding is being explored in Colorado. Specialized weather stations are being developed to
characterize seeding potential for operations and evaluations.
There are 40 total sponsors of winter seeding and several of them are: Southwestern WCD,Dolores WCD,City
of Durango,Durango Mountain Resort,Florida WCD,Pine River Irrigation Distirct,Pagosa Areas W&S,
Gunnison County,Crested Butte Ski Area,Crested Butte W&S,Town of Gunnison, Collbran WCD,Grand
Mesa WCD,North Fork WCD,Fruitland Mesa WCD,Crawford WCD,City of Grand Junction,Colorado
Springs Utilties,and Denver Water,Colorado Springs utilities,Northern Colorado WCD.
Expected program costs for winter 2012-13 are$175,000 Vail,$300,000 Front Range Water Council(Upper
Colorado,$300,000 Telluride&San Junas,and$90,000 at Gunnison.CWCB will have$175,000 from a FY
2013 allocation and expects$150,000 from the Lower basin,$15,000 from NM for a total of$1.25 M.

7. List any feasibility study or scope of work that has been completed or is now in progress for the
proposed project or study.(Submit one copy with this application):
Allthough not completed for two winters there are good initial results from the state of the art cloud seeding full randomized
cloud seeding research program sponsored by the Wyoming Water Development commission.That program has spent$14M
and eight years and seeks to develop results with a 90-95%confidence in statistically significant results.
For 2012-13 in progress is an update of a ten year data set that characterizes seeding potential by warm and cold cloud
conditions statewide.This study performed by HDR Engineering will be helpful to determine what months are best for seeding
and what areas are better for warm cloud(propane)and cold cloud(silver iodide)seeding.
For 2012-13 also in progress is an MOU with the Colorado Avalanche Information Center to develop modeling guidance for
cloud seeders based on new 4km resolution weather modeling.Cross sections of modeling in the target areas will be provided
for"thresholds"of wind speed,temperature,cloud water,and precipitation rates need to initiate operations.The data will be
archived and used for analysis of contractors seeding periods versus modeling results.
