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 creaturesfrom worms to fish to crabsneed oxygen to survive.
Status:
Water quality data gathered between 2007 and 2009 indicate that about 12 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 decrease from 16% in 2006 through 2008.
