Guys, I am just saying. Three interconnected ponds ... not by intention ... but by subsurface. It just seems a bit hopeful that they only connect with each other in a goldilocks way where fixing the neighbors dam will fix them all. My 2 cents go to esshup's tack on the problem, but I concede to your wisdom Augie and Stressless, will watch with interest, and wish you success with this.
BTW. That's a great fish.
