I build ponds for a living, started it last year, started with the company im with on a 40x30 pond with a water fall and a 200" stream and a water bog that fed the stream. We use Aquascape free form pond kits, they are awsome and look great. I would contact them. If you have questions PM me.
I've also been told the county will come dig me a pond if I pay them. Not sure how much it would cost though. I'm still looking for land first. Once that's done then I can start planning. Thanks for informing me about the tilapia ban
If your talking about a decent sized pond they might even pay for stocking somewhat depending on what your stocking. I know here in TX the government pays for stocking a percentage of the fish like your typical pond stocking fish for us which are channel catfish and largemouth bass. The river pond idea sounds great, +1 on the pbass stocking it would be just like yall's canals in south florida anyway and if your lucky they would spawn and multiply like mad.
Personally when I read the river pond idea the thought of bagarius yarelli immediately popped into my head either those or payara and dorado because with a river setup you could control the current and setup a pool/riffle sequence and have several drops to have mini waterfalls to add to the aeration ~Trent
i'd make a pond at the end with all the intakes. then the outputs are at the beginning or the river/stream and it would also give fish a place to rest.
my idea in words.....
pond 45 ft circle (just for reference) by 4ft deep
Looks like I'm going to have to wait to build it, unless I do it on a MUCH smaller scale. The biggest yard we can find in our budget now is about 2/3 acre.
