The 2009 Bay Barometer, the annual report on the health of the Chesapeake Bay, has been released. The health remains poor (a 45 out of possible 100). The USGS contributes to this report by updating information about nutrient, sediment, and stream flow to the Bay, trends in the watershed, and advising on information about stream health. ...read more

To better understand how the land is changing and to relate those changes to water quality trends, the USGS funded the production of a Chesapeake Bay Watershed Land Cover Data Series (CBLCD) representing four dates: 1984, 1992, 2001, and 2006. The USGS is in the process of interpreting and publishing statistics on the land cover change from 1984-2006 in the Bay watershed and will publish land change forecasts based on observed trends in the CBLCD over the coming year.
