Mill Creek Recreation Area

Mill Creek Recreation Area and the associated Bennington Lake landscape provide trails and open-space recreation east of Walla Walla.

Mill Creek Recreation Area

The Corps of Engineers’ flood-control project supports an outdoor network where creek, lake and upland scenery form different parts of the visit.

Consult the current project map and notices to choose an entrance and permitted activity. Reservoir water levels and seasonal conditions vary, so do not assume a particular shoreline or water recreation opportunity. The photograph shows an upland recreation route within the project area rather than the lake at a guaranteed water level.
