A combination of overexploitation, habitat loss, and water diversions has contributed to significant declines in Chinook salmon populations in California over the past century (Yoshiyama et al. 2001). Thermal stress is a serious challenge facing the remaining Chinook salmon in California. Dams have played a substantial role in eliminating access to cooler historical habitats and have fundamentally altered the hydrology of most California rivers (Lindley et al. 2007; Poff et al. 2007). The majority of historic salmon habitats is now above impassible dams, restricting populations to lower elevations with higher ambient temperatures. The combination of increased climate variability (Lindley et al. 2007), restricted habitat, drought, and high water demands for human and agricultural use translates to an increased likelihood of thermal exposure for Chinook salmon (Brown and Bauer 2010).","tracks":[]}
