Middle Rio Grande Isleta Reach Riverine Restoration Project
Draft Environmental Assessment

The New Mexico Interstate Stream Commission (NMISC) is proposing to implement the Isleta Reach Riverine Restoration and Habitat Improvements for the Rio Grande Silvery Minnow and Bosque Ecosystem (project), a river restoration project in sections of the Isleta Reach of the Middle Rio Grande (MRG) from the southern Isleta Pueblo border to the San Acacia Diversion Dam (Figure 1.1). The NMISC is working in collaboration with the Middle Rio Grande Conservancy District (MRGCD) in implementing the Post-fire Bosque Restoration in the Middle Rio Grande: A Landscape-Scale Approach Towards Revitalization of an Ecosystem, an ecosystem restoration project funded through a grant proposal submitted to the U.S. Forest Service Collaborative Forest Restoration Program (CFRP). The combined projects will provide benefit for the federally listed Rio Grande silvery minnow (Hybognathus amarus; silvery minnow), Southwestern Willow Flycatcher (Empidonax traillii extimus; flycatcher), and the Rio Grande ecosystem as a whole. The combined projects, when implemented, will contribute to the Middle Rio Grande Endangered Species Collaborative Program’s (Collaborative Program’s) goal of meeting the habitat restoration requirements as stated in Element S of the Reasonable and Prudent Alternatives (RPA) in the March 2003 Biological Opinion (2003 BiOp: U.S. Fish and Wildlife Service [USFWS] 2003). This document covers the two separate but collaborative projects between the NMISC and the MRGCD listed above.
