Restoring and protecting the region’s Great Waters – the Great Lakes, Chesapeake Bay, Long Island Sound, Narragansett Bay, Lake Champlain, Gulf of Maine, and the Upper Mississippi, Potomac, Susquehanna, and Delaware rivers – is a high priority at the Institute. The Institute conducts research and provides support to ecosystem protection and restoration advocates in order to present a strong and effective voice in the policy-making process.
