need a general idea as to what my budget would need to be if trying to build a similar lake
....as often stated on this board...."it depends".
In my mind I have always thought roughly that pond building costs done by an experienced pond building professional and turn-key are between $7000-$10,000 per acre of pond....of course there are tons of variables as far as terrain, soil, run-off, depth desired, dam type, spillway, drain pipe, syphon system, area access, what part of the country, and level of expertise/professionalism of the pond builder.
Just an FYI...I would think most pond owners on this site have ponds much smaller than 22 acres. My largest pond is just under 4 acres. I guess ideally I'd like to have a 8-10 acre pond.....it really depends on your wants, desires, and budget, but most of us are happy with ponds much smaller than 22 acres.
BTW....where in Texas are you?
