I recently discovered the spot where water is extracted from Shoal Creek and pumped to the big treatment plant up on the hill. From here, to my tap.
The creek that flows from the lake in the park merges with Shoal Creek just upstream from here, which means we get their water also. The spot where last years tubers ended their run is, just upstream from here, in fact, this is the dam we warned them about if they missed their stop.
So, everybodys crap flows right down to our water supply, and yes, that is a dogs tail lower right...
