The Chesapeake Bay watershed covers 64,000 square miles, spanning six states and Washington, D.C
The Chesapeake Bay watershed is a large basin that covers 64,000 square miles and includes parts of six states: New York, Virginia, West Virginia, Pennsylvania, Maryland, and Delaware. It also includes the entirety of Washington, D.C. The watershed is home to a diverse range of flora and fauna, with over 3,600 species of plants and animals, including blue crab and bald eagles. The Chesapeake Bay is the largest estuary in the United States and is a crucial resource for the region, providing jobs, recreation, and food for millions of people.
The watershed is facing significant pollution issues, mainly from excess nutrients and sediment runoff from urban landscapes and agricultural operations. Lawn fertilizer has been identified as a major contributor to water pollution, with nutrients such as nitrogen and phosphorus washing into nearby waters. States like Maryland are taking steps to control nutrient-laden runoff from agricultural fields, but more needs to be done to regulate the use of fertilizers.
Pennsylvania, in particular, plays a crucial role in the restoration of the Chesapeake Bay. About half of the state drains into the bay, and the Susquehanna River, the bay's largest tributary, provides about 50% of its freshwater. Penn State's College of Agricultural Sciences is working to bring together farmers, industry, and government agencies to develop science-based solutions for reducing pollutants in the watershed.
The population in the watershed has doubled since 1950, leading to increased development and destruction of forests and wetlands that previously filtered pollution. To protect and restore the watershed, state and local leaders, environmental organizations, and community groups are collaborating through initiatives like the Chesapeake Bay Program and Watershed Implementation Plans (WIPs). These plans aim to reduce pollution and protect land across the entire watershed by engaging local communities and stakeholders.
The Chesapeake Bay watershed is a valuable ecological and cultural treasure that is facing significant threats from pollution and human activity. By bringing together various stakeholders and implementing science-based solutions, there is hope that the watershed can be protected and restored for future generations to enjoy.

The Susquehanna River supplies half of the bay's freshwater, but also agricultural pollution
The Susquehanna River is the largest tributary of the Chesapeake Bay, providing about 50% of its freshwater. However, it is also a major source of agricultural pollution, delivering about 40% of the nitrogen pollution, 20% of the phosphorus pollution, and a heavy load of sediment pollution to the bay. The river's ancient water system runs through thousands of miles of streams and is the lifeblood of central Pennsylvania and the Chesapeake Bay.
Agricultural practices, including manure runoff, agricultural stormwater runoff, and nutrient imbalances, are significant contributors to the pollution in the Susquehanna River. Excess nitrogen and phosphorus from manure and sewage contaminate the local ecosystem, affecting both groundwater and surface water. The Susquehanna River Basin has seen an increase in manure production due to intensive livestock operations, exacerbating the pollution problem.
The Chesapeake Bay watershed, of which the Susquehanna River is a part, covers a vast area of land that drains into the bay. This watershed is home to a diverse range of plant and animal species and is an important ecological treasure. However, the population in the watershed has doubled since 1950, leading to increased development and agricultural activities that threaten the health of the bay.
Efforts to reduce pollution in the Susquehanna River and the Chesapeake Bay watershed are underway. Penn State University and its College of Agricultural Sciences is working with farmers, industry, and government agencies to develop science-based solutions. The university has also proposed "manureshed" management, which aims to guide the sustainable use of manure resources by matching areas of crop demand with manure sources.
The health of the Susquehanna River and the Chesapeake Bay is crucial not only for the ecosystem but also for the region's economy and well-being. The bay provides jobs, recreation, and food for millions of people. By addressing agricultural pollution and implementing sustainable practices, it is possible to improve water quality and protect this valuable natural resource.

Cover crops can reduce agricultural pollution by preventing erosion and absorbing excess nutrients
The Chesapeake Bay Watershed covers over 64,000 square miles and includes parts of six states: Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia, as well as the entirety of Washington, D.C. The watershed encompasses the Chesapeake Bay and its five largest rivers: the Susquehanna, Potomac, Rappahannock, York, and James. More than 100,000 streams, creeks, and rivers, known as tributaries, flow through this watershed, connecting communities to the Bay.
The Chesapeake Bay and its watershed are facing threats from pollution, unsustainable resource harvesting, and habitat destruction due to human activities. Agricultural pollution, in particular, is a significant issue, with Pennsylvania contributing the largest share through the Susquehanna River. To address this, various initiatives are being undertaken, including the development of strategies by Penn State's College of Agricultural Sciences to involve farmers, industry, and government agencies in implementing science-based solutions.
Cover crops play a crucial role in reducing agricultural pollution by preventing erosion and absorbing excess nutrients. They provide ground coverage, protecting the soil from the impact of raindrops and reducing water runoff. Cover crops also improve soil structure by rooting into the soil profile, enhancing water infiltration, and increasing soil organic matter.
Cover crops are effective in reducing nutrient leaching and runoff, thereby preventing excess nutrients from reaching waterways. They can scavenge residual nitrogen, converting it into proteins and reducing nitrogen loss. Additionally, cover crops can decrease soil erosion by up to 90%, minimizing the displacement of soil and the associated pollutants, such as nitrogen and phosphorus, into waterways.
By utilizing cover crops, farmers can contribute to the overall health of the Chesapeake Bay Watershed. Cover crops help improve water quality, reduce pollution from agricultural activities, and mitigate the negative impacts of human activities on the region.
