asakiyume: (holy carp)






Behold the powerful falls at the Holyoke dam. Holyoke Gas and Electric generates power here.



This dam is a barrier to fish that need to get upstream to spawn. There have been various means of solving this problem, but at present it's a literal elevator, a huge mechanism powered by giant turbines and with great chains that lift boxes of water, packed with fish, up above the falls. Yesterday Wakanomori and I went to see it--a marvelous experience!

It has very cute signposts:
Enter Fishway

In the informational room, there's a diagram that shows how the elevator works. You can see the giant turbines:

And a tally of how many fish have been lifted: yesterday was a record for American shad. (In the colonial days, they used to say that when the shad were running, you could walk across the Connecticut river on their backs.)
