The overarching goal of the three-year Lower Santa Cruz River Basin Study is to identify where physical water resources are needed to mitigate climate change impacts and improve water reliability for the municipal, agricultural and environmental sectors in the Basin.  Basin Studies are collaborative studies cost-shared between the Bureau of Reclamation and non-Federal partners to evaluate the impacts of climate change and help ensure sustainable water supplies. 

Study partners include the Southern Arizona Water Users Association, the Arizona Department of Water Resources, the University of Arizona, Cortaro-Marana Irrigation District, the Central Arizona Water Conservation District and the Pima Associations of Governments.  Throughout the process, the study will engage regional stakeholders, including those representing municipal, agricultural, environmental, industrial and tribal water providers and users.

Eve Halper is a Natural Resource Specialist for the Phoenix Area Office of the Bureau of Reclamation.  She has overseen water resources studies throughout Southern Arizona, including the Sierra Vista Subwatershed and the Nogales and Green Valley areas.  Her study partners include the Upper Santa Cruz Providers and Users Group, the City of Nogales, the Arizona Department of Water Resources and the Upper San Pedro Partnership.  Dr. Halper received her Ph.D. from the University of Arizona in Geography with a minor in Remote Sensing in 2011.  Her research includes studies of the relationships between Tucson’s surface temperature, green spaces and residential water use. She also holds an M.S. in Environmental Engineering and Science from Manhattan College in New York.

Kathy Chavez develops, collaborates and implements water policy and advises on State and local water resource issues impacting Pima County. Ms Chavez contributes technical expertise on sustainable water resource planning efforts and leads the County’s Local Drought Impact Group to monitor drought conditions and recommend response actions.
