Projects Funded by U.S. Bureau of Reclamation
• Environmental enhancement projects need funds to secure water supplies (Megdal et al, 2006 “Projects to Enhance Arizona’s Environment”, Gerlak, et al., Water Policy, 2009)
• Public interest in preserving and enhancing riparian areas (Katz, 2006)
• Connect water conservation to environmental concerns (Schwarz and Megdal, 2007, 2008; Megdal and Bate, 2009)
