Access at seashore locations
The Nauset Marsh Trail bridge was destroyed in a storm last winter. For current conditions, check at the Salt Pond Visitor Center. More »
It is difficult to overstate the importance of water as a resource. Amplifying the importance of water on Cape Cod is the fact that the fresh water supply comes solely from an underground aquifer system that is recharged almost exclusively through precipitation. With this in mind, the Cape Cod National Seashore, in collaboration with the United States Geological Survey, has developed a standardized, long-term methodology of monitoring hydrological activity on the Outer Cape.
The freshwater aquifer of the Outer Cape is bound laterally and below by salt water and is divided into four distinct flow "lenses." These flow lenses are detailed in the map below. Coastal hydrological processes are also of great interest, especially as they relate to salt marsh restoration projects throughout the Seashore.
Climate change, sea-level rise, and increased withdrawal rates from groundwater all have the potential to significantly impact the fresh water resources critical to the human population and the sensitive coastal ecosystems of the Outer Cape. The Seashore's long-term hydrological monitoring program will provide a better understanding of the effects of both natural and human-induced change on groundwater levels of the Cape Cod aquifer.

Cape Cod National Seashore is one of the most important nesting areas for the federally-threatened Piping Plover. Abundant in the 19th century, the beach-nesting Piping Plover declined in the 20th century, but have begun to recover as a result of active protection and visitor education.
