Washington will open a five-day coastal razor clam dig on Thursday along beaches north of Long Beach.

Long Beach and Kalaloch aren't included in any of the digs, all of which begin at noon. Low tides are predicted at dusk and early evening all five days.

The digs are:

Thursday and Friday: Twin Harbors only.

Saturday: Twin Harbors, Mocrocks.

Sunday: Twin Harbors, Copalis.

Monday: Twin Harbors, Mocrocks.

Washington Department of Fish and Wildlife officials originally wanted to include Kalaloch, but rescinded the openings because the federal shutdown will keep Olympic National Park staff from assisting.

Biologists said another dig, Feb. 1-3, will depend upon another round of tests for marine toxins.

Oregon's popular Clatsop County beach digging areas are closed until March 1.

Clams on Clatsop beaches and Long Beach peninsula remain smaller than those in the genetically separate colonies farther north.
