., Table A4. Matrix of flow and temperature recommendations, hypotheses, and relevant studies for Reach 3 (White River confluence to Colorado River confluence) of the Green River. Language for anticipated effects and uncertainties was taken from Muth et al. (2000), U.S. Department of the Interior and Western Area Power Administration (2005), U.S. Fish and Wildlife Service (2005), or U.S. Department of the Interior (2006). See Table 4 for details of specific studies. Primary studies (bold) and supporting studies are linked to Anticipated Effects (A) or Uncertainties (U) are ordered sequentially.
