SB126 Weather Modification Program Died in chamber

2024 Regular Session
HB130 Cloud Seeding Pilot Program Died in chamber
New Mexico's cloud seeding pilot project would have addressed one of western water law's thorniest questions—whether artificially enhanced precipitation belongs to existing rights holders—while providing state liability protection for cloud seeding activities. The bill passed the House but died in the Senate despite clearing committee. Last update
