ANNAPOLIS, Md. (AP) — Chesapeake Bay dead zones are down this June from last spring when heavy rains pushed them to levels not seen in decades.
The Maryland Department of Natural Resources says samples collected in early June show 12 percent of the bay's main stem had low oxygen levels, down from the same period last spring when a third had levels too low for life. The long-term average is 17 percent.
DNR says warmer, drier conditions this winter, compared to the extremely wet spring last year may be the difference.
