The county supervisors are literally trying to make it rain, as they approved the 2013-14 cloud-seeding program with hopes that Twitchell Reservoir in San Luis Obispo County and Lake Cachuma will collect some much-needed water. Cloud seeding, which the county has used since 1982, involves injecting raindrop-promoting silver iodide into the clouds. This year’s program will cost $307,375 and be carried out from November through June.
