Location of study populations (A), Arroyo Seco (blue) and Piru Creek (orange), and temperatures at each site (B). Circles indicate each study site location. Purple hatched shading shows the full range of anadromous O. mykiss in North America98. Dark red rectangles indicate impassable barriers to fish migration (dams) and red triangles indicate partial or temporal barriers to migration (e.g., road crossings and other human-constructed or natural features that require high flow for fish passage). Black arrows indicate flow direction. Stream temperatures were recorded at 15-min intervals using Onset Pendant loggers. Orange and blue lines indicate mean daily stream temperatures and gray shading represents minimum and maximum daily temperatures.
