All is good on the coastal beaches for razor clam digging, and marine toxin levels remain well below the cutoff range or nonexistent.

Digging is open Sunday, Dec.  1 (-0.9 at 5:13 p.m.) at Long Beach, Twin Harbors and Mocrocks; Monday, Dec. 2 (-1.4 at 5:59 p.m.) at Long Beach, Twin Harbors and Mocrocks; Tuesday, Dec. 3 (-1.7 at 6:44 p.m.) at Long Beach, Twin Harbors and Mocrocks; Wednesday, Dec. 4 (-1.7 at 7:30 p.m.) at Long Beach and Twin Harbors; Thursday, Dec. 5 (-1.4 at 8:17 p.m.) at Twin Harbors; Friday, Dec. 6 (-1.0 at 9:05 p.m.) at Twin Harbors; and Saturday, Dec. 7 (-0.3 at 9:56 p.m.) at Twin Harbors. Digging is open from noon to midnight each day.

Digging was excellent since the most recent openings began Friday, Nov. 15 through Wednesday, Nov 20. During the digs from Nov. 15-20, at Long Beach diggers averaged 11.1 clams per person from Nov. 15-17; Twin Harbors it was 14.6 from Nov. 15-20; Copalis it was 11.9 on Nov. 15-16; and Mocrocks it was 14.5 from Nov. 15-17.

Barring any marine toxin issues diggers should see excellent digging now and well into spring time.

Here are the additional evening digging dates going into the winter holiday period:

Saturday, Dec. 14 (low tide is -0.1 feet at 4:45 p.m.) at Long Beach, Twin Harbors, Copalis and Mocrocks.

Sunday, Dec. 15 (-0.3 at 5:26 p.m.) at Long Beach, Twin Harbor and Mocrocks.

Monday, Dec. 16 (-0.4 at 6:03 p.m.) at Long Beach, Twin Harbors and Mocrocks.

Here is the marine toxin update by state Fish and Wildlife and the state Department of Health:

Listed below are the most recent marine toxin levels, as announced by the state Department of Health (DOH) on Nov. 21.
This is the second of two rounds of razor clam samples required by WDOH before any recreational razor clam opener.

All samples are below the action level for both domoic acid and PSP and DOH has allowed state Fish and Wildlife to proceed with this first December 2013 razor clam harvest opener.

According to Dan Ayres, the head state Fish and Wildlife coastal shellfish manager, recall before a beach can be opened for the harvest of razor clams, DOH protocol requires that all razor clam samples collected from that beach must test under the action level  of 20 parts per million (ppm) for domoic acid and 80 µg/100g for PSP on both of the two required sample collections.

In the results below, you will see values for a third marine toxin, okadaic acid. This is a toxin that is produced by a surf zone dinoflagellate from the genus Dinophysis. These cells have been observed in coastal surf zone water samples by the state’s harmful algae monitoring project.

As result, the DOH has added screening for the presence of okadaic acid to the tests conducted on razor clam tissue sampled prior to any razor clam opener. The action level for okadaic acid is 16 µg/100g.

High levels of Okadaic acid in shellfish tissue can produce Diarrhetic Shellfish Poisoning or DSP.

For more details regarding okadaic acid and DSP, go to http://www.doh.wa.gov/CommunityandEnvironment/Shellfish/BiotoxinsIllnessPrevention/Biotoxins/DiarrheticShellfishPoisoning.aspx

Note that in all of these samples; only razor clam meat tissue is tested.

Long Beach Reserve

Domoic acid =  3 ppm

PSP = none detected

Okdaic  acid = none detected

Twin Harbors Area

Domoic acid =  2 ppm

PSP = none detected

Okadaic  acid = none detected

Copalis Area

PSP = none detected

Okadaic  acid = none detected

Mocrocks Area

Domoic acid =  4 ppm

PSP = none detected

Okadaic  acid = none detected
