During the fall of 2021, the Columbia County Public Works Department began constructing a new irrigation reservoir between holes No. 2 and 3, near the tee blocks on hole No. 3 at the Touchet Valley Golf Course. Using excavated material to backfill the Touchet River levee along hole No. 2, they created a gentle slope to the top of the levee and constructed a new tee block on hole No. 3.
