<p>The power plant I ran had an emergency release valve which
generically was called a hollow cone valve. Properly it was a
Howel-Bunger Valve. I suspect that is what they are talking
about. for us it opened automatically whenever there was a power
outage so as to maintain instream flows, and also as the only
mechanism to drain down the lake in an emergency situation other
than through the generators, which by themselves couldn't release
enough water to do the job. Making repairs to such an item is
difficult if it must be available for service at all times. I
have no idea if tht is the case with TR Dam.</p>
