What pump would lower a lake 10 m? 1

[PEng222]

I'm not a pumping expert but need to figure out whether it would be possible to lower the level of an alpine lake by pumping so that a water intake can be installed.

Facts:

1. The lake is about 700 m long, 200 m wide.

2. The inflow is about 2 m3/s.

3. I need to lower the lake level 10 metres

4. The lake is in a high alpine, remote location where there is no power. There will be 4 wheel drive and heavy equipment road access to the site so I can bring in generators and pumps.

5. I can afford to take a couple of weeks to lower the water, so I figure I need to be able to pump out at 3 m3/s (2 m3/s to deal with inflow, and another 1 m3/s to actually lower the water level).

So any advice on how I might do this, and where I might get more info on the WEB would be appreciated.

I'm serious about the ice.

Superelevate the road and build a snack shack at the top, and you can probably find people who would pay to ride a "bob-floe" down.

Thanks for the suggestions- I think I have enough information now to help make a decision.

I don't think sliding lake ice down the road would work- trust me, if you saw the site, you'd understand. Would be fun, though.

It would be of interest to hear what you finally decide on for this project.
Good luck with it.

Siphons are THE way to go rather than pumping. Simply figure out your energy costs diesel or electric with pumping and youll be able to justify significant initial temporary construction costs for discharge lines etc. You need a small eductor pump to prime the siphon lines, you only need a valve on the down stream discharge point , not the inlet.

Ive done this in the Arctic.. similiar volumes and heads.

And Im pretty good with explosives if you need help there. I live in Alberta so I probably familiar with your site.t
