Dissolved Oxygen Standards Attainment
Dissolved oxygen (DO) refers to the amount of oxygen that is present in the water. Just like humans, all of the Bay's living creatures—from worms to fish to crabs—need oxygen to survive.
Status:
Water quality data gathered between 2006 and 2008 indicate that about 16 percent of the combined volume of open-water, deep-water and deep-channel water of the Bay and its tidal tributaries met dissolved oxygen standards during the summer months. This is a slight increase from 12% in 2005 through 2007
