Boistfort (/ˈbɔɪstfɔːrt/)[2] is an unincorporated community in the northwest United States, in Lewis County, Washington, about twenty miles (30 km) southwest of Chehalis.

[3] The first non-indigenous settlers to the Boistfort prairie was the family of Charles and Elizabeth White who migrated from Peoria, Illinois beginning in April 1851.

Relatives of the family followed that year and into 1853, growing the community further during the time with other settlers staking additional claims, creating farm land and building homes.

[11][12] Notable test pilot Scott Crossfield (1921–2006) moved to the area in his teens and graduated from Boistfort High School in 1939.

[15] Boistfort is located in a prairie valley marked at its eastern edge by the Chehalis River and on the west by Mill Creek.

The creek had lost salmon and plant habitats due to a combination of warming waters and erosion brought on by consequences of flooding and human activities.

The work culminated in slowing down the flow of the creek to prevent erosion and restoring the floodplain and course of the waters.

Coming after flooding in the Chehalis River basin after the Great Coastal Gale of 2007, the plan was offered by a group of citizens but the Boistfort dam did not materialize.
