Update: Thank you, Pond Boss. I received my back issue, good article by Mark Cornwell and it's great to see the pictures he provided. Yes, they are inefficient, as you noted, Scott. We might get 1 gallon per minute pumped up (coincidently, about the same as the leak) and lose maybe 10 doing so. But I like the idea of water ram down by where the leak is as there would still be a little lagoon there from the waste value and once it's set-up, we can just, more or less, forget about it. (The water turbine is still under consideration to replace the electric pump.)
I also enjoyed the article on dragonflies! We have plenty of dragonflies and even now in the middle of summer hardly any mosquitoes. I can sit in the evening, get lost in the beauty and enjoy.
