This claim is false. While Michigan had a "Weather Modification Control Act" (Act 279 of 1978), it was repealed on May 30, 2000. This means that in 2001, there were no specific laws prohibiting cloud seeding in Michigan. There is no additional information to confirm that cloudseeding has been banned after the repeal. According to a 2025 dataset on U.S. cloud seeding activities, Michigan has not been a major participant in such programs, but that does not equate to a legal ban. While some states have introduced or passed legislation to restrict weather modification, Michigan is not listed among those with active bans as of 2025.
