Lake Lewis Chapter

Meetings | Community Activities | Officers & Contacts

The Lake Lewis Chapter is based in the Tri-Cities, Wash., and represents south-central and southeastern Washington and the adjacent areas in Idaho and Oregon.

The chapter is named for Lake Lewis, the large temporary lake that formed in the Pasco Basin when floodwaters were held back by the hydraulic dam caused by Wallula Gap. For more information about Lake Lewis, click here.
