Low dissolved oxygen volume averaged 0.97 cubic miles from June through September. Crabs, fish, oysters and other  Read the Rest…


Maryland Fishing Report: September 26

With the fall equinox behind us, the days are getting noticeably shorter. There’s no sweeter time of the year – or place to be — than late September and October in Maryland, whether you are a fisherman or a hunter or just someone who likes to enjoy the sights and sounds of autumn.


August 2018 Hypoxia Report

Dissolved oxygen conditions for Maryland’s portion of Chesapeake Bay returned to near average for the month of August, reports the Maryland Department of Natural Resources. The department tracks hypoxia throughout the summer during twice monthly monitoring cruises. Low dissolved oxygen volume was at a record low (0.26 cubic miles) in late July, due to sustained  Read the Rest…


Bloede Dam Removal Begins

Partnership Effort Restoring Patapsco River, Improving Public Safety Conservation leaders, federal and state officials, and other partners gathered today on the Patapsco River to celebrate the removal of Bloede Dam – an effort that has been a decade in the making, and will have major benefits for fisheries, public safety, recreation, and the health of  Read the Rest…


Late July 2018 Hypoxia Report

Heavy Rainfall and Sustained Winds Helped Produce Best Recorded Results Ever Due to extreme summer weather, dissolved oxygen conditions in Maryland’s portion of the Chesapeake Bay mainstem were the best ever observed in late July, reports the Maryland Department to Natural Resources. The department tracks hypoxia throughout the summer during twice monthly monitoring cruises. The  Read the Rest…


Early July 2018 Hypoxia Report

Dissolved oxygen conditions in Maryland’s portion of the Chesapeake Bay mainstem improved in early July, according to the Maryland Department of Natural Resources. The department tracks hypoxia throughout the summer during twice monthly monitoring cruises. The hypoxic water volume (areas with less than 2 mg/l oxygen) was 1.05 cubic miles, nearly 0.6 cubic miles less  Read the Rest…



Late June 2018 Hypoxia Report

As anticipated, dissolved oxygen conditions in Maryland’s portion of the Chesapeake Bay mainstem worsened in late June. During its twice monthly monitoring cruises, the Maryland Department of Natural Resources found that hypoxic water volume (areas with less than 2 mg/L oxygen) was 1.63 cubic miles, which is 42 percent greater than the late June average  Read the Rest…


Early June 2018 Hypoxia Report

Maryland and Virginia scientists have begun regularly collecting oxygen data as they monitor the health of Chesapeake Bay waters, and track the states’ progress toward restoring the treasured Chesapeake.  The Maryland Department of Natural Resources will track bay oxygen levels throughout the summer during twice-monthly monitoring cruises.


Submerged Aquatic Vegetation Return is Sentinel of Chesapeake Bay Ecosystem Recovery

Department Researcher among 14 Co-Authors in National Academy of Sciences Report A new research article published today in the Proceedings of the National Academy of Sciences analyzes the positive impact of long-term nutrient reductions on an important and valuable ecosystem in the Chesapeake Bay. The research indicates that a resurgence of underwater grasses is due to  Read the Rest…

UMCES and Maryland Department of Natural Resources worked  Read the Rest…



Summer 2017 Hypoxia Report

Maryland’s Water Quality Monitoring Data Indicates Second Best Year on Record Dissolved oxygen conditions in Maryland’s Chesapeake Bay mainstem were much better than average this summer, according to Maryland Department of Natural Resources. The results show that 2017 had the second-smallest Chesapeake Bay hypoxic volume (dissolved oxygen concentrations below two milligrams per liter) since 1985, for the regions and times  Read the Rest…


Late August 2017 Hypoxia Report

Dissolved oxygen conditions in a portion of Maryland’s Chesapeake Bay mainstem were better than average for late August, reports the Maryland Department of Natural Resources. The hypoxic water volume (areas with less than 2 mg/l oxygen) in the study area was 0.33 cubic miles, which is much smaller than the late August 1985-2016 average of 0.80 cubic miles for that reduced  Read the Rest…
