According to the Nisqually River Steelhead Recovery Plan, hatchery stocking of both winter and summer-run fish was pretty consistent between the late 1950's and early 1980's for WSH and mid-1990's for SSH.

WSH stocking was consistent from 1958 - 1981 with the largest releases in 1972 (204,000+) and 1975 (175,000+). Not including those years the releases were fairly small, averaging ~ 21,000 smolts/year. SSH stocking was consistent from 1964 - 1994, averaging 23,000+ smolts/year.
