This program wai considered ineffective even in its day, in view of continued declines in catches. During the last two decades, hatchery production has increased overall, although more so in some species than others. Coho and eteelhead hatchery programs are now reasonably successful, contributing about 40 and 30 percent to the Chehalis Basin catches of each species, respectively (Table 14). On the other hand, fall Chinook and chum programs have not made significant contributions despite long-standing hatchery programs. Hatchery production accounts for most of the summer eteelhead catch, but this run contributes a very small number of fish to the total catch. Success of extensive cutthroat trout releases is impossible to determine, since it has not been evaluated. Pall Chinook Salmon Fall Chinook production has been erratic, although smolt production has increased over the last two decades (Figure 17) and has largely replaced fry releases. The Satsop River hatchery program began before 1970 but production was discontinued in 1979 due to dwindling numbers of adults returning to the Simpson Hatchery (WDF unpubl
