permaculture

[Paul Wheaton <paul@richsoil.com>]

I'm preparing to dig several ponds this year to raise trout.  I'm on the west 
slope of
the rocky mountains about 50 miles south of the Canadian border.

I know that one of the big rules is to never plant trees on a dam.  

I also know that if you want the pond to be cool (which trout require) it is 
wise to
plant trees on the south side of the pond.  

What if the dam is on the south side?

I suppose one could plant a tree that has a lot of spreading habbit and plant 
those at
the dam edges.  Any suggestions on what variety of tree that might be?

I suppose that would be a really good place to build a dock.  

Any suggestions?
