Appendix B (FIG. B1). Percent survival (mean ± S.D.) of smolts from three tributaries (Wells, West, and Salmon rivers) in simulation with no dams, with a 2 d delay at dams, and with a 4 d delay at dams. Data are shown for the original temperature cost functions (Models B, F, and I; black circles), the alternative cold-cost function (Models M, O, and P; gray circles), and the alternative warm-cost function (Models S, U, and V; white circles).
