Talk:Fish ladder

From Wikipedia, the free encyclopedia

[edit] How effective - where? and which designs?

I was discussing the fish-ladder concept with a construction worker familiar with the local dams (Columbia River system), and he called into question the effectiveness of fish ladders in general. He believed that fish (salmon for instance) can get up the ladders, but that in following instrinct to swim down river to the sea, many or most die. Is this correct? Is another part of the cycle virtually completely missing?

Article needs to address effectiveness - and maybe effectiveness in relation to particular designs and specific dams and rivers. - M.C.

[edit] Pictures

This article would be better if the pictures showed fish actually jumping up the ladder.4hodmt 02:38, 20 March 2007 (UTC)
