consequence of the Steelhead’s complex life history. The expected number of
returns in the peak year was 623, with 32 of them expected to stray. The model
indicates a 99% probability that the maximum number of Steelhead strays occurring in a single stream would be 70 or fewer (Fig. 5.7), with 40 or fewer being
females (Fig. 5.8).
