frank--WOW--my ratio of 40 to 45 acre for a 1.5 acre pond is much smaller than your ratio--i actually cut a drainage ditch to increase my watershed by 15 or so acres to it's present size because i was scared of drought like this summer---i could have built mine on the creek which flows nearby but it would have had a watershed as big or bigger than you describe and i was scared to try that due to possibly blowing out the dam, possibly extending the pond onto other property and water constantly feeding thru it---also scared of what all species of everything would end up in mine--beaverpond upstream as well. look foward to meeting you and us looking at each others ponds. thanks
