LONG BEACH, Wash. - Clam diggers have received the go-ahead from the Washington Department of Fish and Wildlife to proceed with the last razor-clam dig of the season, starting Saturday, at four ocean beaches: Long Beach, Twin Harbors, Copalis and Mocrocks.

Two beaches, Long Beach and Twin Harbors, will also be open for digging on Sunday. Digging on all beaches must be completed by noon both days.

The WDFW authorized the digs after a series of marine toxin tests conducted by the Washington Department of Health confirmed the clams are safe to eat.

Low tides this weekend are as follows:

Saturday, (7:23 a.m. -1.2 ft.) - Long Beach, Twin Harbors, Copalis and Mocrocks

Sunday, (8:02 a.m. -1.2 ft.) - Long Beach, Twin Harbors

Diggers will need an applicable 2009-10 fishing license to join in this weekend's dig. April 1 marked the beginning of a new license year. A license is required for anyone age 15 or older. It is strongly advised that diggers to make their purchases before heading to the beach.

Descriptions of the various licensing options are available on the WDFW Web site at https://fishhunt.dfw.wa.gov . A list of state license vendors is available at http://wdfw.wa.gov/lic/vendors/vendors.htm

Under WDFW rules, harvesters may take no more than 15 razor clams and must keep the first 15 taken, regardless of size or condition. Each digger's limit must be kept in a separate container.

Clam diggers are allowed to drive on beaches open to razor clam digging, even those marked "closed to vehicles," provided they remove their vehicles from those areas by noon each day. However, portions of the beaches at Long Beach and Twin Harbors are closed to all public access to protect nesting western snowy plovers, which are listed as threatened under the Endangered Species Act.

At Long Beach, the closed area is located north of the Oysterville Road from the state park boundary north to Leadbetter Point. At Twin Harbors, the closed area is located from just south of Midway Beach Road to the first beach-access trail at Grayland Beach State Park. The closed portion at each beach includes the area beyond the mean high tide line.
