About how many acres drain into the pond? Up here I think they say you need 10-15 acres of drainage to keep a one acre pond full. Someone correct me if I'm wrong.

Found a site that has really helped.

Honda water pump web page

Click on a model and then click on pump select to run a calculator that will give lots of information on how your scenario. Looks like I can get 200gpm for my scenario. The calculator is fun to play with.

If distance or rise turns out to be a problem, maybe you can connect two pumps in series?

Sorry DK, the fish hugger term is not necessarily a negative thing. I agree in principle with making every reasonable attempt to avoid sucking animals through the pump. In the valleys of the south sound we still use approved river intakes to irrigate many of our farm fields, very common and accepted here.

Perhaps you have some suggested screening or contstruction techniques to help avoid sucking aquatic life through a pump in this situation?

The supplied 1/4" hole screen intake on my rented pump did a good job of not allowing the frog type animals from leaving the pond I decommisioned. The problem is that the small screen did a good job of sucking their guts out so I would think that the screen would be quite large.

No reason to be sorry, I actually thought it was funny and forgot to add the smilie face after my comment about adding fish hugger to the list. Considering I'm a gubermint biologist at least for another year or two, it's one of those subjects I'm all too familiar with. I've been walking streams in the summer and come across irrigation pumps sucking up fish like crazy and hate to see it happen. I'm on the road for a few days, but when I get back I'll put together some information on screening. Ultimately, it's not just screen hole size as you found out, but approach velocity as well.

MikeS,

You should probably visit this site: Pondboss . There is a regular poster there (Greg Grimes) who's business is managing ponds and fish in your area.

You should really find out if the watershed flowing into your pond will be sufficient to keep it full. This is the normal way things are done and may/should eliminate the need for a pump except in extreme circumstances.

Lots of other things to read about at the site I mentioned. You will want to fish, I presume? /forums/images/graemlins/smile.gif

How much water is running in the river you are pumping from? I remember a rotary pump that just used the water flowing by to allow it to pump. No electricity, no nothing. This was not a ram pump but some type of rotary. I think it was Lehmans or Cumberland general store but there could be more. This might work for keeping the pond full after it is filled.
