Well, I finally got a .4 acre pond built, filled and stocked with 100 six to 8" CC and a pound of FH. It took them about a week, but they're eating well. I still have to finish up the shoreline and build the dam up more.
I had sand down to about 7', so we dug a 3' x 3' trench down the middle to get enough clay to throw and pack on the sides. It loses about an inch of water every 2 days in this heat and drought. I'll see if I can figure out how to post some pics.
