Figure 18. Spawning escapements for odd- and even-year pink salmon populations in Washington. For each population, an exponential trend line is fitted to the spawning escapements (see Tables 8 and 9 for statistical significance of trend estimates). All populations are odd-year except for Snohomish River pink salmon. In the Nisqually River from 1981 to 1985 and in 1993, escapements were not estimated and a value of 500 was assigned for each of these years for run reconstruction. Escapements in the Elwha River in 1977 and 1979 were assumed to be 14.25% of the Dungeness River escapement (see text for discussion).
