State shellfish managers have added Twin Harbors beach to the next tentatively scheduled razor clam opening, beginning March 24, and canceled four days of digging at Kalaloch beach due to a low abundance of clams.

The proposed razor clam digs, along with evening low tides and beaches, are listed below:March 24, Friday, 5:01 p.m.; 0.5 feet; Mocrocks, Twin Harbors

March 25, Saturday, 5:44 p.m.; 0.2 feet; Copalis, Twin Harbors

March 26, Sunday, 6:24 p.m.; 0.0 feet; Mocrocks, Twin Harbors

March 27, Monday, 7:04 p.m.; 0.0 feet; Twin Harbors

Although WDFW is adding days at Twin Harbors, the department is canceling the remaining four day of digging this season at Kalaloch beach. A recent population survey at the beach indicated far fewer clams than pre-season estimates.

“We’re a little mystified about what has happened at Kalaloch over the last few months,” Dan Ayres, coastal shellfish manager said. “We need to close the beach to digging this spring to protect the small population there.”

WDFW will continue to monitor the razor clam population at Kalaloch, as well as at other ocean beaches.
