This morning’s operations missive from the federal-state-local Middle Rio Grande operations group (by “Middle” here we mean central New Mexico) notes a release of ~100 cubic feet per second of imported San Juan-Chama Project water for environmental flows, an effort to help the struggling Rio Grande silvery minnow. SJC water is removed from the Colorado River Basin in the San Juan mountains of southern Colorado, through a series of tunnels beneath the continental divide, for use in the Rio Grande Basin.
