Earthen dams still exist in many parts of the country — around the world, in fact. Funny thing about them, however… With ready access to a usually reliable supply of water, those dams with steady resevoir levels and good soil produce a thick, rich carpet of grass on them. This lush covering often grows so quickly that it begins to seem impossible to maintain a neatly-trimmed appearance. Folks have been know to comment that it is just proof that you can’t keep a good dam mown.
