More than 10 years after the state began studying Tashmoo Pond as part of the Massachusetts Estuaries Project, a final report on the pond’s declining health is expected to be released this week.

Effective June 1, boaters in Vineyard Haven waterways will be restricted to three days on an anchor. The Tisbury selectmen unanimously voted to approve an amendment to the town anchoring regulations after a public hearing Tuesday.

Work to deepen the channels at the entrance to Lake Tashmoo and at the west entrance to Vineyard Haven harbor wrapped up earlier this month. Sand was placed at the public beach in Tashmoo as well as the public beaches at Grove avenue and Owen Little Way.

On Thursday, Sept. 26, the Tisbury Waterways, Inc. will hold its annual meeting at 5 p.m. at the Katharine Cornell Theatre. The meeting will include a presentation on inshore dredging projects and what to do with the collected spoils. The program is a joint effort by the Tisbury Waterways Inc. and the Martha’s Vineyard Commission.

At approximately 11:30 p.m. on Tuesday, June 25, the tide in Lake Tashmoo reached its highest point and began to roll back. Susie Bowman, a naturalist and teacher at Mass Audubon’s Felix Neck wildlife sanctuary, was there to mark the change with her husband, Woody. After Mrs. Bowman marked the tide’s apex, she began measuring out five-meter by five-meter quadrants in which they would search for pairs of mating horseshoe crabs. This is the couple’s fifth year of horseshoe crab surveying at Lake Tashmoo.
