Some information from the geoduck harvest management plan.

The commercial harvest of geoducks targets the clam population in a relatively narrow band of subtidal Puget Sound; that area down to 70 feet. Keep in mind that geoducks can be found in quite deep water (to depths greater than 650 feet!). Reportedly in many areas of the Sound the deep waters with suitable substrate the bottom in waters are "paved" with geoducks.

The harvest plan targets an harvest rate of 2.7% of the biomass (that in less than 70 feet). By extension if the reported 5 million pounds of clam harvested is 2.7% of the biomass that shallow water biomass would be 185 million pounds. Have not been able to find a total biomass Puget Sound estimate but it would appear that 5 million pounds is a relative drop in the bucket of whatever that biomass may be.

BTW-
Yesterday (7/28) there 8 diver boats that appeared to be harvesting geoducks at Kingston.
