WEATHER MODIFICATION – Amends, repeals, and adds to existing law to prohibit unauthorized weather modification activities and to provide penalties, enforcement, and exceptions.

S 1065 prohibits unauthorized weather modification (such as cloud seeding for precipitation enhancement) and solar radiation management activities within Idaho, classifying violations as misdemeanors punishable by law. It defines key terms like "cloud seeding" and "solar radiation management" to clarify the scope of the ban and authorizes all state law enforcement officers to enforce the prohibition. The bill exempts cloud seeding operations already authorized by the Idaho Water Resources Board under existing water law. It repeals outdated sections related to weather modification districts and funds, updating Idaho Code to reflect this new regulatory framework.
