<br />operati onal program are, therefore, estimated to be $136.6 mill ion per
<br />year. Thus, 9 to 11 dollars worth of benefits would be produced for
<br />every dollar spent to increase water supplies in the region.
<br />
<br />Conclusions
<br />
<br />Cloud seedi ng is but one of several resource management tool s
<br />available to help meet critical water needs. It does not preclude con-
<br />tinued planning and development of other water management alternatives,
<br />nor does it 1 essen the commitment to improved water conservati on prac-
<br />t ices, but the cloud seedi ng alternati ve does have many uni que and
<br />attractive features. Currently, it appears to be the most cost-effective
<br />means of securing additional water. It does not require major, permanent
<br />construction and large-fixed operation and maintenance costs. Moreover,
<br />a decision to employ cloud seeding is reversible on a year-to-year, E~ven
<br />a storm-to-storm basi s wi thi n a season, shoul d hydrology, weather pat-
<br />terns, or public interest so dictate.
