In our Mission Statement, we talk about “Keeping the Waterways in and around Popponesset Bay safe and navigable”.
SPB works closely with the Town of Mashpee’s Waterways Commission. The Town annually dredges the outer channel leading from Popponesset Bay to Nantucket Sound. The sand is then pumped onto the Spit. Currently, the Town excavates between 5,000 and 10,000 cubic yards before April 1, prior to restrictions imposed to protect endangered bird species and certain fish.
We have pursued permits in collaboration with the Town to expand and lengthen the outer channel.
SPB also holds dredging rights to the channel at the southern tip of Popponesset Island. This channel links Popponesset Creek to Popponesset Bay. SPB has posted signs to advise against swimming in this narrow channel due to boat traffic.
