Chesapeake Bay ‘Dead Zone’ to be Average to Slightly Smaller

Hypoxic zone size affected by low river flow and nutrient loading

Washington, DC–(ENEWSPF)–June 13, 2016.  Scientists expect that this year’s mid-summer Chesapeake Bay hypoxic low-oxygen zone or “dead zone” – an area of low to no oxygen that can kill fish and aquatic life – will be approximately 1.58 cubic miles, about the volume of 2.3 million Olympic-size swimming pools. This is close to the long-term average as measured since 1950.
The nutrient loading, from the mouth of Susquehanna River in Havre de Grace, Maryland, accounts for the 10 percent smaller predicted size of hypoxic areas in the Bay this summer.

The anoxic portion of…
