73. Grand Coulee Dam School District

Grand Coulee Dam School District serves a chain of Columbia River communities and many families connected to the Confederated Tribes of the Colville Reservation. Lake Roosevelt Elementary carries students through sixth grade, and Lake Roosevelt Junior/Senior High School continues from seventh grade to graduation. The shared Lake Roosevelt name creates one district identity across communities whose histories include tribal nations, the dam and the reservoir that transformed the region.

Indian Education is part of the district’s ongoing academic and cultural structure. Title VI and Johnson-O’Malley programs support achievement, attendance and graduation while giving Native families a formal role in setting priorities. K–12 academic and cultural staff work across the schools, and curriculum resources help teachers include tribal history and culture throughout the year. This work supports eligible students directly and gives the wider school community a stronger understanding of the place in which it learns.

The high-school program combines college preparation with practical routes. Occupational education includes woodshop, welding, technology, automotive and business courses, and students complete fifty hours of community service before graduation. Upward Bound helps eligible students who may be the first in their families to earn a four-year degree prepare for postsecondary study. Lake Roosevelt Alternative School provides another route for students who need flexibility. A Lake Roosevelt diploma carries expectations of service, practical skill and postsecondary planning within a cultural setting where several histories remain present at once.
