Yeah, bet they would be a tad upset !...it was just a thought though...as a side note, this summer I'm expanding my pond...renting an excavator which will run 1250.00 for one week...pond will go from 1.5 to 2.5 acres...you can move a lot of dirt with an excavator in one week !....you can also rent a backhoe for not much to do your core at the dam...I know we "Mountaineers" are some tough folk, but diggin' a core with a shovel, WOW...got my respect here !!...anyway, good luck !...what kind of fish are you going to put in ?
