Folks in upstate New York hate NYC for the water supply. Much of the economy of the "southern tier" region is crippled by the requirement to keep water quality pristine (NYC being one of few cities that doesn't significantly process incoming water), and to manage water flows (including that of the Delaware River itself) to optimize the reservoirs, at the expense of fisheries and stuff.
