Kind of begs the question why so much local level water stuff is federally regulated.
Why do North and South Carolina have to shell out to manage all their runoff in federally prescribed ways just because all the states on the Colorado river can't get along?
Why does St. Louis and every other "give and take from river" water district have to mandate all sorts of federally prescribed minutia written around assumptions of aquifer depletion? It's not like a lack of low flow toilets is gonna affect anything other than the size of the local water treatment plant.
