Court: No reserved water rights for NM trust land There are no federally reserved water rights for the millions of acres of state trust land in New Mexico, the state Court of Appeals has ruled. The court's decision Wednesday came in a case involving the adjudication of water rights in the San Juan River Basin of northwestern Mexico. In the river system, there are nearly 300,000 acres of trust land. Last year, a state district court in San Juan County rejected the claim made by the Land Office. The Court of Appeals affirmed the decision. The lands conveyed to New Mexico by acts of Congress from 1850 to 1910 "were never withdrawn from the public domain and reserved for a federal purpose. As such, it necessarily follows that any attendant federal reserved water rights that the commissioner now claims in connection with those lands were also not impliedly reserved," the court said in an opinion written by Judge James Weschler. "The Court of Appeals got it exactly right," D.L. Sanders, chief counsel for the state engineer, said in an interview. He said no state court has recognized federal reserved water rights for state trust lands in the West although the legal question has come up in other places, including Arizona and Montana. "By everybody's calculation, this was a huge stretch in the legal theories," Sanders said. Had water rights been reserved for New Mexico's trust lands, Sanders said, it would have been a "sweeping change in law" and disrupted the current system that allocates rights for using water. Federal reserved water rights typically are more senior than those held by private landowners or municipalities in New Mexico, giving them a greater priority in times of drought when not enough water is available to cover the demands of all users....
