Banks Lake Steelhead Plant

[CRO]

I believe that the pipes supply Banks Lake; not the other way around.

the pipes do supply Banks Lake. Walleyes that were planted in Banks went into the pipes and went down into the columbia.

Unless I'm mistaken (it happens), the pumps are Francis Wheels which are designed to pump and to generate so your comment makes sense if GC uses Banks water to generate at the inlet end.

Back to the regularly scheduled smallmouth bait...........

Am I the only one that is...........ahhhhhhh, .......unfamiliar with "Francis Wheels"? Who the hell is Francis Wheels?

Green Lake?

That was my thought as well. Or Beaver Lake.

Would these fish they are releasing even grow into decent size (like in the 16” + range)?

Because when they released them about 7-8 years ago, I remember most of them got harvested pretty quickly as WDFW mainly stocked them in put & take fisheries and upped the daily limit to 10. I don’t recall hearing about any holdovers being hooked years later.

No…I’m with ya

A Francis wheel is basically a high velocity nozzle that squirts into cups located on the turbine wheel. Chances of something surviving going through the nozzles are low.

Did I get that right @salmo g ?

Feed the homeless…..the last time they had to stock steelhead smolts due to saving the wild fish…..they dumped them into Fenwick, Green and screwed up Rattlesnake! 19,000 in Rattlesnake after it was a great selective fishery….they changed it to catch and kill and the meat fishermen threw back the steelhead and kept the nice rainbows.

Any guesses on where the Tokul fish will end up?

Green Lake?

Sorry, no. You're thinking of a Pelton turbine. There is zero fish survival through Pelton turbines. Francis turbines are commonplace, but not highly conducive to fish survival due to large sheer forces. A Kaplan turbine can have pretty high survival (85%) because they don't generate large sheer forces around their blades. Kaplans can only be used where the static head doesn't exceed something like 90' or so. I don't know how high Banks Lake is relative to the Columbia River.

Banks Lake gets its water from Lake Roosevelt above Grand Coulee dam. On google Earth you can clearly see the facility that they built. The date it was built and how it works i dont know. I thought that Banks was originally filled from water taken below Grand Coulee in 1951. The collection system that is on Lake Roosevelt could be part of a new Hydro project that will be between Roosevelt and Banks.
