Ririe Dam was
built by the U.S. Corps of Engineers on near identical geology in the
next adjacent watershed to Teton Dam, at the same time Teton was constructed.
It
has never experienced the seepage problems that caused Teton Dam's untimely
demise. Find out why in the presentation "Could a Safe Dam
Have Been Constructed
At the Teton Dam Site?"
