BALTIMORE (AP) - The size of the Chesapeake Bay's low oxygen "dead zone" is down and dry weather is getting the credit.

The Maryland Department of Natural Resources says testing last week found nearly 12 percent of the bay had poor oxygen levels, nearly half of the long-term average for this time of year. The dead zone dropped from about 30 percent of the bay in July, which typically is when the zone peaks each year.
