Razor clam diggers can return to Mocrocks and Copalis beaches for a three-day dig beginning March 18.

The Washington Department of Fish and Wildlife approved the opening at Mocrocks and Copalis after marine toxin tests showed the clams are safe to eat.

The dig, which is on evening tides, will coincide with the annual Ocean Shores razor clam festival, said Dan Ayres, WDFW coastal shellfish manager.

The upcoming dig is scheduled on the following beaches, dates and low tides:

March 18, Friday, 4:15 p.m.; 0.7 feet; Mocrocks, Copalis

March 19, Saturday, 5:07 p.m.; 0.5 feet; Mocrocks, Copalis

March 20, Sunday, 5:50 p.m.; 0.4 feet; Mocrocks, Copalis

Last month, state shellfish managers approved a razor clam dig that runs through March 31 at Long Beach. Although Long Beach is open daily, optimal digging conditions occur when the low tide is one foot or lower, Ayres said.
