Superstorm Sandy released 11 billion gallons of sewage from East Coast treatment plants into bodies of water from Washington, D.C., to Connecticut.

That's according to a study by the nonprofit science journalism group Climate Central. It says that's equivalent to having Central Park covered 41 feet high with sewage.

Most of the overflow was due to storm-surge flooding that inundated sewage treatment facilities.

The sewage spilled into surrounding waters and even some city streets, most of it in New York City and northern New Jersey.

New York conservation officials have updated the advice they give people about the safety of eating fish from the state's waterways.

Among this year's changes is the addition of the Lewiston Reservoir in Niagara County and part of the Beaver River in Lewis County to the advisory list. And there are changes in the fish species included in advisories for four Adirondack waters: Fall Lake in Hamilton County; Francis Lake in Lewis County; Schroon Lake in Warren and Essex counties; and Cumberland Bay on Lake Champlain.
