The one thing that we can't afford to see is a catastrophic failure at the leach pad. That would kill the fishery right quick. It would kill German Gulch.

It's starting at basically ground zero. There's no floodplain, no meanders. It's one of the worst spots on the creek.

Right now, it's pretty much a straight shot and it washes those contaminants down into Silver Bow Creek. If we create these pool habitats that are normally so good for fish, we could potentially see selenium and cyanide levels rise as contaminated sediment settles out.
