Dataflow Data are available as either surface maps of integrated dataflow data, or as a direct raw data download. You can query for maps or download dataflow data on our: DATAFLOW Surface Maps & Data Query
Where can I find long-term data?
- Our longest-running sampling program is our Long-term Monthly Monitoring, which began in 1984. You can view stations, date ranges, and download data from our: Long Term Monthly Monitoring Station Information Table These data are submitted to the Chesapeake Bay Program Data Hub, where you can download multiple stations at once, and choose your preferred date range and parameters. To access this data, visit: Chesapeake Bay Program DataHub NOTE: The answer to the next question in this FAQ includes a tutorial for downloading from the DataHub.
- In addition, some of our Continous Monitoring stations also have long data records. You can find out longevity of sampling by using either our:Continuous Monitoring Station Information Table ...or you can use this visual timeline chart: Continuous Monitoring Station Timeline

How do I find out if an area is safe for swimming?
- Local government health departments measure bacterial counts at public swimming beaches. The local health departments coordinate with the Maryland Department of Health and Mental Hygiene and the Maryland Department of the Environment (MDE) regarding reporting of closures. Links to those resources are all on our Eyes on the Bay page dedicated to:Swimming Health Related Resources
US EPA has a Beach Advisory and Closing Online Notification (BEACON) national map database to show locations of beach closings and health advisories:
- EPA Beach Information and BEACON
General advice that is provided regarding swinning in open waters is:
1. Persons with comprised immunity and/or open cuts should avoid water contact.
2. Avoid swimming 48 hours after heavy rainfalls. Heavy rainfalls wash pollutants and nutrients into waterways that can stimulate bacterial growth.
3. Wash well after water contact.
Are the crabs and fish from my river safe to eat?
- For all information relating to this topic, please consult: Maryland Department of the Environment's Fish Consumption Advisory Website.

Is it legal to spread cremated ashes in the Chesapeake Bay?
- After some research and speaking to the Executive Director of the Maryland Board of Morticians (BOM) and Funeral Directors, here is what we found:
1. In Maryland it is NOT legal to spread ashes in the Bay or rivers or public lands.
- 2. Ashes can only be put on private property of your own or someone who agrees to it.
- 3. Maryland abides by federal law, so you can spread ashes at sea beyond 3 nautical miles but you should check with your licensed funeral director on specifics.
- Here are a few links which may be helpful:
- Document on cremation specifics given to MD decedent's loved ones
- EPA Regulations on Burial at Sea
- Board of Morticians (BOM) website
