THE PENNSYLVANIA CHESAPEAKE BAY PROGRAM
We All Live Downstream
The Chesapeake Bay is our nation's largest and most productive
estuary. The Bay provides recreational and commercial opportunities
for humans and is "home" for many animals.
Over recent years, the Bay has become a "victim" of pollution.
Many Pennsylvania land use practices affect water quality in the Chesapeake
Bay. The decline of the Bay has impacted not only the wildlife found
living in and around its waters, but also humans who rely on the Bay
as a source of income.
How can the actions of Pennsylvanians affect the Chesapeake Bay?
The Chesapeake Bay Basin is made up of thousands of miles of
rivers and streams that supply freshwater to the Chesapeake.
- The Chesapeake Bay Basin stretches from upstate New York to the
Tidewater Region of Virginia. The drainage area covers 64,000 square
miles or 41,000,000 acres.
- Pennsylvania makes up over one-third of the entire Chesapeake Bay
Basin, more than any other state.
- About half of Pennsylvania (52%) lies within the Chesapeake Bay
Basin.
- Within Pennsylvania's portion of the Chesapeake Bay Basin, the Susquehanna
River drains 92% of the watershed and the Potomac River drains another
7%. The remaining 1% of the watershed drains from the Elk Creek and
Northeast River in Chester County, and Deer Creek and Gunpowder River
in York County.
- Three million people, or about one-quarter of the entire Chesapeake
Bay Basin population, lives in Pennsylvania.
The Susquehanna River flows 440 miles from New York through
Pennsylvania and Maryland and into the Chesapeake Bay. Most of the river
lies in Pennsylvania.
- The Susquehanna River has an average flow of 19 million gallons
of water per minute, the highest average flow of any river in the
eastern United States.
- The Susquehanna River supplies 50% of the freshwater entering the
Bay. Pennsylvania's portion of the Potomac River contributes an additional
2% to the Bay's freshwater supply.
- In the upper portion of the Chesapeake, as much as 90% of the freshwater
comes from the Susquehanna River
- Although the average depth of the Chesapeake is only 30 feet, a
channel over 180 feet deep runs through its center. The channel is
the original Susquehanna River bed, dating back to the Ice Age.
Nutrient pollution -- caused by excessive amounts of nitrogen
and phosphorus -- impacts local water quality and the Chesapeake Bay.
- Excess nutrients cause an overgrowth of algae, called algae blooms.
Algae blooms deplete oxygen supplies and block sunlight needed by
aquatic plants and animals.
- Pennsylvania contributes an estimate 36 percent of the nitrogen
and 25 percent of the phosphorus entering the Bay.
- In the upper portion of the Bay, about 3/4 of the nitrogen and 1/2
of the phosphorus comes from Pennsylvania
- Animal manures and commercial fertilizers can pollute local waterways
if applied in excess of crop needs. Over half of the nitrogen and
the phosphorus entering the Susquehanna River comes from agricultural
runoff. Improper fertilization of residential lawns and gardens, malfunctioning
septic systems, industrial activities, and air deposition of nitrogen
and phosphorus can also affect water quality.
The Pennsylvania Chesapeake Bay Program was launched in 1984 in response
to an Environmental Protection Agency study that reported the health
of the Bay is declining. The Pennsylvania Bay Program is supported by
state and federal funds. The Program is administered by the Department
of Environmental Protection's Bureau of Water Quality Protection and
is implemented at the local level by county conservation districts.
In 1987 Pennsylvania furthered its commitment to protect and restore
the Chesapeake Bay and joined the governors of Virginia, Maryland, and
the District of Columbia in the signing of the Chesapeake Bay Agreement.
The Agreement set a goal of reducing nutrient loads entering the Bay
by 40 percent by the year 2000.
The Pennsylvania Chesapeake Bay Program is:
- A cooperative project between state, federal, and local agencies
and organizations
- A voluntary effort of Basin landowners to help reduce agricultural
runoff;
a nonpoint source pollution control program within Pennsylvania's
portion of the Bay watershed.
- A technical and financial assistance program for farmers who are
interested in installing prescribed management practices to reduce
water pollution.
- An educational outreach effort teaching farmers, students homeowners,
local governments, and private industries about Pennsylvania's connection
to the Chesapeake Bay.
About half of the PA Bay Program funds are devoted to cost-sharing
Best Management Practices (BMP's) that reduce agricultural pollution.
Pennsylvania's Bay Program also offers grants for demonstration projects
and education al activities that show how Pennsylvanians can improve
local water quality and protect downstream areas including the Chesapeake
Bay.
