Water gives life to our national parks, shaping land and sustaining life. In its various forms—springs, wetlands, aquifers, geysers, stream, lakes, and oceans—water is fundamental to natural processes and visitor enjoyment. From Acadia to the Grand Canyon, Everglades to Glacier, water is central to features, wildlife, recreation, and aesthetics.
Yet, outside the parks, the health of these waters is being jeopardized. Demands for water use are putting a strain on waters that flow through national parks. Similarly, pollution from activities beyond park boundaries, and sometimes within, damages the quality of park waters. Parks, once viewed as isolated and remote, are increasingly becoming threatened by activities occurring in their watersheds.
NPCA recognizes that the health of our national parks is directly linked to the health of the waters that surround them.

NPCA's latest report explores two historical parks in the Chesapeake watershed, Colonial National Historical Park on the James and York Rivers, and Fort McHenry National Monument and Historic Shrine on the Patapsco River. It recounts what the rivers looked like before significant agricultural practices, oyster harvesting, and extensive human development. It recommends options to restore the Chesapeake Bay and its national parks to a highly productive ecosystem with cleaner water, fewer toxic contaminants, and more abundant aquatic and terrestrial life. Our national parks help us recognize what has been lost so we can see what we have the opportunity to regain.
