The USGS collects multiple types of data in the Chesapeake Bay watershed. The Data Catalog contains a list and links of all the types of Chesapeake information from USGS. Some of the most relevant data related to streams and rivers is highlighted in the “tracking status and trends indicators of stream health”. Land cover, use, and change data are also highlighted.

### New High-Resolution, Land-Use and Change Data Improves Decision-Making

With support from the CBP, the USGS, Chesapeake Conservancy and the University of Vermont developed an improved 1-meter resolution land use/land cover (LULC) data set for the Chesapeake Bay watershed.
