The $6 million Clark Fork Delta restoration project, near Clark Fork, Id., started last fall, It targeted 680 threatened acres of the delta. Heavy equipment was used to rebuild shorelines and raise the height of partially submerged areas. The intent is to preserve what remains of the delta and start to recover some ground. Katherine Cousins, Idaho Department of Fish and Game biologist, and her team planted 90,000 plants. When it didn't rain in May, she worried they would die, but the lake come up in time.
