the majority of the Cape. Groundwater continues to flow into and out of ponds, feeding streams, and flowing towards the coast, finding sea level when it enters our estuaries and embayments, as water seeks the lowest elevation. Our drinking water comes entirely from groundwater. This sole-source aquifer, which is protected by local, regional, state, and federal restrictions, provides all of the Cape's drinking water. Watersheds Watersheds connect nearly all of the Cape's waters, fetching water and releasing it into the ocean. There are 101 watersheds on Cape Cod that discharge into the ocean. 53 of them flow into embayments, which are vulnerable to nitrogen contamination, while the others discharge directly into the ocean. The Cape Cod Commission produced a regional framework for protecting and improving water quality and tracks progress in implementation through the Section 208 Water Quality Management Plan for Cape Cod. Fishing Cape Cod Bay is a world class fishing destination for many anglers. Popular fishing methods used to fish Cape Cod bay include trolling, live bait fishing, light tackle fishing, and fly fishing. Fisherman typically fish off the coast of the South Shore (Massachusetts) and inner cape for fish such as Blue Fish, Cod, Flounder, Striped Bass, Bonito, Tuna, Mackerel, Pollock, Haddock, and even Sharks. Fishing season typically takes place between May and October. Although plenty of fisherman prefer to fish from shore rather than a boat, Massachusetts requires a Recreational Saltwater Fishing Permit for anyone 16 years of age or older. Many coastal towns have fishing piers, and boat charters that provide daily trips into Cape Cod Bay to catch fish. The most popular bait used is sea clams, and live mackerel. Threats to Cape Cod Bay Pollution and Water Quality Per the Cape Cod Commission, the bay is experiencing water problems. Although nutrients like nitrogen are an important aspect of aquatic ecosystems, excessive amounts can damage water systems. Cape Cod's estuaries are vulnerable to the effects of excess nitrogen due to a number of factors. Nitrogen is poisoning the saltwater barrier that has characterized the peninsula. On Cape Cod, centralized wastewater treatment plants are not extensively employed due to the expense and challenges associated with widely spread housing, as well as huge seasonal fluctuations in population due to summer tourists. Typical backyard sewage systems, which are not aimed at eliminating nitrogen, are responsible for an estimated 80% percent nitrogen dumping on Cape Cod Bay. The
