 Where they're ready to swap out dams, put in a different type of structure. Exactly. Aren't they scheduled to lower the lake again here at the end of this month, I think? I think this fall they'll lower the lake and get work started. But how long that dam's been there since the Work Project Administration built that reservoir? 30s. Late 30s? Yeah. Right before World War II. So it's almost 100 years old.
