Okay lousybreed, I'm impressed! :bowing:
Sorry for getting into this conversation 2/3 ways into it, but I skimmed the previous posts and this is looking very very nice.
As for the waterfall (you
must have one!), what were you thinking? The splash over like you sketched out, or more of a fountain-type design?
My dad and I build a large Koi pond (25'x12'
ish x4') about 14 years ago, and we developed a pumping system that draws the water up hill (12 foot run) and empties the water into a man-made riverbed which overflows (i.e. waterfall) into the pond vai a 1 foot drop. It's not premised off of any overflow design, but rather a simple pump. Similar to a sump, but this is specifically desgined for Koi ponds (so of course it cost more), but it can move over a 1,000G per hour. Thankfully it's adjustable!
I'm going over Saturday for Draft-Day and will try my best to remember the camera to grab some snap shots for you! It's a lined pond vs. a hard walled raised pond, but this system will work on any design. (I will draw something up and scan/post it here for your view).
Not sure if these are covered or not already, but how are the side edges married up? I used metal brackets and wooden supports. It will be much clearer once the pics are finished. The metal brackets? What type of base and liner are you planning on? 45 mill EPDM liner, base will be newspaper and walmart blankets!!!
Sorry to be a pest, but this is coming along awsomely! Is awesomely a word? It should be!

No problem, thanks for the motivation!
Love the pictures bro!:dance2:
