The technique is based on variables thai arc <br />affected by cloud seeding such as precipitation and snowpack. "Inc control sites are <br />unseeded areas located up".."ind from the target sites. The target and control analyses have <br />been mad!: and published by North American Weather Consultants. The data and <br />analyses have been reviewed and confinned by the Division of Water Resources. A <br />summary of the results from the analyses follows. <br /> <br />4 <br />
