In the context of a rapidly expanding population and the consequent demand for water, the arid southwestern U.S.A. especially exemplifies the divergence between water supply and environmental ecological needs. To date few applications of the ELOHA framework have been comprehensively applied to high need areas, though some areas have developed one or more components of the ELOHA framework (Henriksen et al., 2006; Kennen et al., 2007; Apse et al., 2008; Kennen et al., 2007; Kennard et al., 2009).

In fact, the Colorado River has the most complete allocation of its water rights of any stream in the world and is also one of the most heavily regulated (U.S. Bureau of Reclamation, 2000). The 2015 Colorado State Water Plan has identified priority water diversion projects to meet the gap in water supply between municipal water supply and demand, which is estimated to total more than 500,000 acre‐feet statewide by 2050 (Colorado Water Conservation Board, 2015). In response to the 2015 Colorado Water Plan and 2005 legislation, nine basin roundtables were created as a voluntary, collaborative process to help the state address the gap in water supply in each basin (Sanderson J. S., Bledsoe, et al., 2012). One of the objectives of each basin roundtable is to complete basinwide…
