Thanks for the reply Cecil.
By above ground overflow, do you mean just use the "emergency spillway" for all the drainage needs. Do you know anything about putting in a pipe for winter livestock water? Or is this also a leaky-dam waiting to happen. I do have cattle and presently have to chop ice in the deep of winter, but I could spend the money on a freeze-proof waterer and eliminate the extra pipe from the lake project.
