Savage, welcome to Pond Boss!
F/Rod gives good advice on some questions that may be answered by whoever the builders are.
With the 'muddy' water, there'll be no way to tell how deep the pond may be from sight, but you may be able to take a john boat or float tube out and check depths.
If the 'pond' was built to handle run off during construction, I don't think it will be much more than a few feet deep. That can easily dry up in Texas summers.
Thank you Sunil.
So if this turns out it's a retention/infiltration pond, not deep and would/could dry up, would this potentially be a good start since it's already partially dug out for actually draining it and doing it proper? I'm not sure I'd be opposed to that, depending on what I'd spend.
Since we're just coming out of summer and there's this much water, it really has me wondering... Thank you for your advise.
