Nine of Washington’s 101 commercial shellfish growing areas are threatened with closure this year because of pollution. Sixteen growing areas were listed as threatened areas in 2009 and 10 in 2010.  Locally, the threatened shellfish areas include the Grays Harbor Coast and the Naselle River. Each year, the state looks at water quality data collected from shellfish harvesting areas. In nine areas, data for this year show that poor water quality or failure to manage potential pollution sources could result in the downgrade of the harvest area. Work is underway to find and fix pollution problems in many of the threatened shellfish growing areas.
