WildEarth Guardians v. U.S. Army Corps of Engineers, No. 18-2153 (10th Cir. 2020)Annotate this Case
The Rio Grande was one of only a handful of rivers that created critical habitat for plants, animals, and humans. “And it is a fact of life that not enough water exists to meet the competing needs.” Recognizing these multiple uses, Congress has authorized the Bureau of Reclamation and the Army Corps of Engineers to maintain a balance between the personal, commercial, and agricultural needs of the people in New Mexico’s Middle Rio Grande Valley and the competing needs of the plants and animals. WildEarth Guardians claimed the Army Corps of Engineers failed to protect the needs of two endangered species that live along the river: the Southwestern Willow Flycatcher and the Rio Grande Silvery Minnow. The group filed suit under the Endangered Species Act, arguing the Army Corps of Engineers failed to exercise its discretion and consult with the U.S. Fish and Wildlife Service (FWS) about alternative water management policies that would help protect these species. The district court concluded the Army Corps of Engineers was not authorized by the statute to allocate additional water to species’ needs and therefore was not required to consult with FWS. Finding no error in the district court’s reasoning, the Tenth Circuit Court of Appeals affirmed.
