One dairy cow produces close to eight tons of manure a year. On big farms, that poses a serious, and regulated, waste disposal problem. In the spring and summer, farmers can spread manure on their fields before planting. But in the winter, all that manure has to be stored somewhere.
Milk Street Dairy in Jefferson County has more than 1,000 dairy cows. The owners are constructing a seven-million gallon lagoon to hold liquid manure. The site is on Ridge Road in the town of Rutland. It overlooks the Black River, and Watertown city officials aren’t happy.
