Razor clam digging will be open Friday and Saturday at Long Beach, Twin Harbors and Mocrocks.The Washington Department of Fish and Wildllife approved the two nights of digging after marine toxin tests showed the clams are safe to eat. No digging will be allowed before noon.Low tide is -0.4 feet at 6:48 p.m. on Friday and -0.4 feet at 7:23 p.m. on Saturday. Most diggers begin an hour or two before low tide. Diggers must keep the first 15 clams dug. Each digger’s clams must be in a separate container.Digging tentatively also is scheduled for Nov. 25-26, Dec. 10 and Dec. 22-23 with final approval depending on marine toxin tests.“This season’s tides are not as favorable as those in the past few years,” said Dan Ayres, coastal shellfish manager for the Department of Fish and Wildlife. “Low tides will occur later in the day, so diggers will have to be prepared for the dark during evening digs in fall and winter.”An annual razor clam license costs $11. A three-day license is $6.60.
