Sustainable Water Management in the Southwestern United States: Reality or Rhetoric? (July 2010)

Published in PLoS ONE, this study used four scenarios to explore the potential effects of alternative growth and water management strategies on river flows. Under the base population projection, we found that rivers in seven of the 18 study watersheds could be dewatered due to municipal demand. Our approach provides a low-cost method to identify where alternative water and growth management strategies may have the most impact, and demonstrates that such strategies can maintain a continued water supply for both people and the environment.

San Pedro River Wet-Dry Maps (February 2010)

The San Pedro River wet/dry mapping dataset is a community effort to track the river’s health by monitoring the persistence of surface water during the driest time of each year. It is created by recording the end points of every wet section of the San Pedro River during June each year. Maps depict the wet portion of the San Pedro River.

Ecological Implications of Verde River Flows (February 2008)

Presents a literature review and results of a May 2007 workshop where 35 subject experts from 16 agencies and institutions synthesized the state of knowledge for central Arizona’s Verde River. Report describes the river’s ecosystem, including its hydrology, geomorphology, riparian, and aquatic habitats, and fish and wildlife species – and how components would respond to changes in surface- and groundwater flows.

Arizona Statewide Freshwater Assessment GIS Data Package (June 2006)

Includes 3 spatial datasets mapped to 1:100,000 scale hydrography for Arizona, including 1) the habitat for 33 native fish species, 2) former and current perennial surface flow for Arizona’s rivers, and 3) the distribution of threatened and endangered species that require aquatic or riparian habitats.
