Impacts of the Rosemont Mine on Hydrology and Threatened and Endangered Species of the Cienega Creek Natural Preserve

Document ID: 
048900
Year Published: 
2014
Summary: 

This report provides the most comprehensive evaluation of the extensive water resource data that has been collected at CCNP as it relates to potential impacts from the Rosemont mine. We focus first on developing robust predictive models, apply those models to estimate a range of impacts to baseflow and length of streamflow, question some past analyses and assumptions about the lack of connection between surfacewater and groundwater, highlight key uncertainties that inhibit our ability to understand the full breadth of impacts from the mine, and finally, we combine the water resources data with our best understanding of the distribution of habitat for the aquatic and riparian T&E species that currently occur or recently occurred at the CCNP to estimate loss of habitat as a result of the mine.
