Abstract:

Parametrix received funding through the Middle Rio Grande Endangered Species Collaborative Program (Program) in Fiscal Year 2006 to develop scientifically-based restoration recommendations intended to improve the habitat and population status for two federally endangered species: the Rio Grande silvery minnow (silvery minnow) and the southwestern willow flycatcher (flycatcher). The project area focus is along the Middle Rio Grande between the San Acacia Diversion Dam and the San Marcial Railroad Bridge (see Exhibit 1-1), herein referred to as the San Acacia Reach.

The restoration recommendations in this report are based upon review, analysis, and interpretation of existing data and reports. General project site reconnaissance was also performed, although site-specific field data collection was not part of this project. Limited site-specific data was available across the 47-mile project reach to support site-specific project recommendations. These projects, therefore, should be considered conceptual at this time. Future project sponsors will need to gather and analyze site-specific data to validate project feasibility, refine project cost and water depletion estimates, and develop detailed project monitoring plans.
