A good point, but I think TWRA is the only one with enough beef to step up to this plate. So I'd like to see some action there. If I were a resident (and I may be some day), I'd spend some of my time pushing for this.

TWRA seems to try to stay away from land use issues. TDEC is overstretched. A lot of regulations are on the books but utterly unenforced, or token efforts are accepted. If you're ever driving through the new construction on US 79 between Clarksville and Dover, notice how the silt barriers are placed along the crests of ditch banks, often on the far side of the ditch from the constuction. Those fences are actually on some of the highest points of land in the area, and certainly have zero effect on silt heading south to the Cumberland or north to the Red. And that's the way it's done in plain sight! I've worked on new housing developments and around farms and the token efforts there are even more pitiful.
