Most people don’t actually understand how Summersville Dam works, so here’s the breakdown:
Historically, water was discharged through those massive tubes everyone associates with Gauley Season. But after the hydroelectric project was completed in 2001, they started harnessing the water’s energy through turbines instead, releasing it from underneath the dam. Nowadays, seeing the big tubes actually open is reserved mostly for big rain events, when the Corps needs to control flooding.
There’s a lesser known small tube that serves the opposite purpose, keeping the river running during droughts when the inflow isn’t enough to generate—often in the fall. If you go down to the Gauley River during dry spells, you’ll see this small tube releasing water to maintain the aquatic life, and you can observe this massive plume, because it’s still massive, from the observation deck if you’re brave enough to head down to the riverbed.
Small tube, big job. 💦
