This is where the Pipe goes. There were other Pipes taking off, one going uphill the other way and one going downhill, probably to feed more Tanks for Cattle....The Horizontal Pipe Stub at this end had a flow coming out of it at about a Gallon per minute and it was clean and clear, as was the Water in the Tank. Must be some time of Overflow system going out one of the other Pipes, otherwise this Tank would be overflowing....
