Rio Grande Silvery Minnow v. Bureau of Reclamation, called Rio Grande Silvery Minnow v. Keys in its earlier phases, was a case launched in 1999 by a group of environmentalists against the United States Bureau of Reclamation and the United States Army Corps of Engineers alleging violations of the Endangered Species Act and the National Environmental Policy Act. The case resulted in significant changes to water and river management in the Middle Rio Grande Basin of New Mexico in an effort to reverse the damage that had been done to the habitat of two endangered species. The waters of the middle section of the Rio Grande in New Mexico, running from north to south past the city of Albuquerque, have been used for irrigation for at least 1,000 years.
