Upper Penobscot Bay
Softshell Clam Survey 1966-67.

SUMMARY In 1966, the Federal Water Pollution Control Administration surveyed about 90 percent of upper Penobscot Bay's shores for soft-shell clams. (Unsurveyed areas were industrial sites & other non-clam habitat.) The survey was part of the study: "Pollution of the Navigable Waters of the Penobscot River & Upper Penobscot Bay in the State of Maine." Top clam areas were Stockton Springs and Searsport, followed by Northport and Belfast.

The total harvestable softshell clam resource of the upper bay for 1966 was estimated at 96,000 bushels, with a value to diggers of $1,876,000 and a community multiplier value of $5,216,400.
