Razor clam diggers will have a few more beaches to consider in late March and April, following a decision March 8 by state shellfish managers to add digs to a list of dates previously announced.

The Washington Department of Fish and Wildlife (WDFW) is planning new digs at Long Beach in March and at Copalis and Mocrocks in April, based on recently updated harvest estimates showing a sufficient number of clams in those areas to support additional openings.

"After last weekend's opener, we still have ample clams to provide additional digging opportunities for those beaches," said Dan Ayres, WDFW shellfish manager.

Final approval on upcoming digs will be announced after marine-toxin test results confirm the clams are safe to eat.

The first added digging opportunity will be at Long Beach on March 31, which is also the last day that a 2013-14 fishing license is valid. Beginning April 1, diggers age 15 or older must have a 2014-15 fishing license to harvest razor clams.

The department also scheduled additional digs at Mocrocks and Copalis beaches in mid-April.

"Openings in late April and May will be announced after we evaluate harvest levels again next month," Ayres said.

Proposed digs are tentatively scheduled on the following dates, beaches and low tides. The current schedule is:

--March 26, Wednesday, 3:52 p.m .; 0.3 feet; Twin Harbors

--March 27, Thursday, 4:48 p.m .; 0.1 feet; Twin Harbors

--March 28, Friday, 5:38 p.m .; 0.0 feet; Twin Harbors, Long Beach, Mocrocks
