152. Onalaska School District #300

A working fish hatchery sits on the Onalaska High School grounds. Students raise salmon and trout, maintain the water system and eventually release the fish into local waters. The project connects science with the forests, farms, lakes and outdoor economy around this eastern Lewis County community, and it gives the high school a public role that residents can see beyond games and graduation ceremonies.

Onalaska Elementary, Middle and High School form a compact local route. The community grew from a strong logging history and now includes farms, nurseries and small businesses alongside families who still work in timber-related fields. Students meet that changing economy through horticulture, aquaculture, cuisine and other applied courses, while band, choir, digital arts, athletics and clubs keep the secondary experience broad. Summer work in the aquaculture program has also combined environmental maintenance with science credit and paid student experience.

Axe Virtual Academy gives some students an online high-school arrangement, yet most children grow through the three local schools and become familiar with the high-school campus long before ninth grade. A young student may first know the hatchery through a visit or community event, then later take responsibility for the fish, the water source and the release itself.
