View Full Version : Escapees???

After reading the latest info on the jack breeding program I got to wondering just how many fish of any species that are stocked in to our dams actually survive the drop.

That is, do many make it past the dam walls and into the river systems?

Do many survive?

If they do we are going to have a ball with jacks in a few years time. Surely it will make the saltwater fishery better as well won't it? Or will the bigger fellas be happy enough to stay put?

Many bass survived the drop during floods at Wivenhoe Dam quite a few years back. So its possible.

Yes fish survive the drop over many of the dams, I think a big fact in this suvive and dammage to them when they hit the bottom relates obviously to the drop but the size of the fish. That is the bigger the fish the more momentum they gather and therefore hit the bottom harder. At the nothpine dam I have noticed a higher death and injury rate in the bigger fish that go over. But essentially lots of fish suvive the trip over the dam wall.
