The Chesapeake Bay Program’s analysis of the health of the Chesapeake Bay and its watershed reveals a resilient ecosystem that continues to face challenges from excess nutrients, chemical contaminants and ever-increasing resource demands. The Bay Barometer, released today, offers a science-based snapshot of long and short term health trends and watershed-wide progress by partners toward a healthy Bay ecosystem.
Though indicators of ecological health continue to reflect the reality of an impaired Bay, our restoration work and efforts to reduce the flow of nitrogen, phosphorous and sediment into rivers and streams give Bay officials cause for optimism. Similarly, new data provides insights on lag times across the watershed, or that period of time that occurs between restoration work and visible improvements in water quality. While lag times mean it will take time to see restoration results, they also give us reason for optimism: our actions do have an impact. Finally, CBP’s new method for tracking the attainment of water quality standards in tidal segments of the Bay applies the most up-to-date science to historical data, offering a long-term perspective on how the Bay’s waters have changed since 1985.
The following are some highlights from the 2012-13 Bay Barometer.

Factors to Consider
Determining the current health of the Bay and its tributaries is as complex as the ecosystem itself. Factors such as annual rainfall, river flow and the increasing need to meet demand for resources to support a growing population—food, housing, infrastructure—mean we have to understand the complex science if we are to bring the Bay into balance. The Chesapeake Bay Program’s role is to offer the public all the data, in its most clear form, so that each person can assess the health of our waters, fisheries and habitats and the progress that partners and communities are making toward a restored ecosystem.
Looking at data over time helps scientists understand natural variations as well as the long-term effects of restoration efforts. The data provided in the 2012-13 Bay Barometer reflect the Bay’s health over the course of many years, and in some cases, decades. The publication provides a snapshot of the best available information from 2012 and 2013 on the Bay’s health and current efforts to protect and restore our national treasure and its watershed. Additionally, news bullets and “Learn the Issues” sections offer readers some context of other relevant work taking place in the watershed.
“Bay Program partners have made significant strides in moving us ever closer to a healthy, restored Bay watershed. Although we would like to see more immediate results from our actions, we will have to exercise persistence and patience as the actions we take to rebuild balance and resilience back into this complex ecosystem take effect and show up in the data from our monitoring networks. The Chesapeake Bay Partnership will continue to report health and restoration information each year, work to improve our science and reporting systems and look forward to observing the gains we will achieve from the work we are doing today.”
--Nick DiPasquale, Director, Chesapeake Bay Program
“Restoring and protecting the Chesapeake Bay watershed is—and must be—a collaborative effort. As program partners work towards the goal of reducing nutrient and sediment pollution in the Chesapeake Bay, we will also work to protect and restore our habitats, fisheries and local waters. Whether we are talking about urban or agricultural lands, we all must do our part for the health of our waters and the environment.”
