Thanks for the replies...

teehjaeh57, do you irrigate with a windmill or an electric pump? If windmill, what brand and size? How many gpm or gph are you getting? Does it constantly run? If so, do you have a slight overflow? Do you know your average evaporation?

I definitely plan on drilling a well to supplement water. I plan to build a house here in 5 - 10 years, and then never move again. So a good investment doesnt worry me...

Im supposed to be going to look at a pond a local guy built somewhere in the 6+ acre range that he keeps full running a 5 horse well pump at 50 gpm...
