In Iowa we beg people to put buffer strips along our rivers and lakes to keep them relatively clear of sediment. It doesn’t work. Farming the road ditches has become a popular practice, as any motorist with his eyes open can see. It shows up in our lakes — the mud is strangling lakes all over Northwest Iowa such that they might not see another century — and eventually in a huge nitrified dead zone in the Gulf of Mexico.
