A dam could derail the Chesapeake Bay cleanup

The cleanup of the Chesapeake is dependent on a dam that has outlived its usefulness.

The $19 billion bid to clean the Chesapeake Bay and restore its health rests on a simple plan: cut the amount of nutrient waste — involving nitrogen, phosphorus and sediment — that causes most of the bay’s pollution.

For nearly seven years since the cleanup started, the federal government and six states in the bay’s watershed have reduced municipal sewer overflows that pour nitrogen and phosphorus into rivers that feed into the bay and cut the fertilizers and other nutrients that run off from hundreds of farms. They also counted on the Conowingo Dam to block massive amounts of sediment in the Susquehanna River from smothering bay grasses that nurture marine life.

But that part of the plan has gone very wrong.
