New Mexico water agencies are slowly piecing together a regulatory puzzle in order to store Rio Grande water in Abiquiú Reservoir for middle valley irrigation this summer as El Vado Dam is repaired. But an objection from Texas water managers could interfere with the reservoir’s use for non-pueblo irrigators. The U.S. Army Corps of Engineers operates the northern New Mexico reservoir on the Rio Chama. Nabil Shafike, the Army Corps Albuquerque District’s water management chief, said Abiquiu was once authorized only to store Colorado River Basin water that is diverted into the Rio Grande Basin with a series of tunnels and dams for the San Juan-Chama Project.
“All the Corps reservoirs – Abiquiú, Cochiti, Galisteo and Jemez Canyon – work as one unit to protect the middle valley from flood,” Shafike said. “Any storing of native (Rio Grande) water would require a deviation from the current operation.”
The agency is weighing two potential changes at Abiquiu:
• A request from the New Mexico Interstate Stream Commission to store up to 45,000 acre-feet, or 14.6 billion gallons, of Rio Grande water in Abiquiú each year for release later in the season to meet middle Rio Grande irrigation demand.
• A request from the U.S. Bureau of Reclamation to store up to 20,000 acre-feet, or 6.5 billion gallons, of Rio Grande water in Abiquiú each year to meet direct flow right for the six middle Rio Grande pueblos of Isleta, Sandia, Santa Ana, San Felipe, Santo Domingo and Cochiti.
The Army Corps could approve both storage plans or may choose only one.
