I'm no expert, but seems like I remember 3 things about plumbing, H on Left, C on Right, and ____ don't flow upstream. Now if there's a spill in Lake Norman, how can that not go all the way to Wateree?? Besides that, Tega Cay was spilling into Wylie last year, and Great Falls was spilling into Wateree several years back. Seems like the Catawba is turning into the sewage dump.
