Bill Information: H0669 – Cloud Seeding and Weather Modification Ban

Session: 2026 Regular Session
Status: Dead
Last Action: Reported Printed; Filed in the Office of the Chief Clerk (Feb 16, 2026)

Bill Summary

This bill completely bans all cloud seeding and weather modification activities in Idaho by repealing existing authorization statutes and replacing them with a prohibition. The legislation declares that cloud seeding lacks provable outcomes, citing a 2024 Government Accountability Office finding that effectiveness estimates were not statistically distinguishable from zero. The bill further asserts that such activities violate Idaho’s constitutional guarantees of inalienable rights.

The ban applies to all aerial and ground-based cloud seeding projects and programs, requiring immediate cessation of existing activities. Any person or entity—public or private—who conducts cloud seeding or attempts weather modification faces felony charges punishable by five years imprisonment and a $100,000 fine per violation. The bill removes all statutory authority previously granted to watermasters and the Department of Water Resources director to develop, coordinate, or fund cloud seeding projects designed to augment water supplies. The legislation includes an emergency clause making it effective immediately upon passage.

Overall Assessment

This bill receives a total score of 1, reflecting its alignment with principles of minimal government regulation in natural resource management while creating a negative impact on water resource management. The legislation advances the metric on Natural Resources and Environment by prohibiting government intervention in weather modification and reestablishing state primacy over environmental policy through the elimination of cloud seeding programs. The bill demonstrates a commitment to reducing government involvement in natural processes and opposing artificial manipulation of weather patterns.

The bill receives a negative score on Water because it eliminates a tool previously used for water supply augmentation, particularly during drought conditions. By removing the authority of the Department of Water Resources to conduct or coordinate cloud seeding projects, the legislation restricts options for managing water resources in a state where water availability is critical for agriculture and other industries. The bill scores positively on Responsibility in Government by reducing the scope of government programs and eliminating spending on weather modification activities, though this represents a modest alignment with fiscal restraint principles.

Rating: 1
