Even after Eastern Point Lighthouse was lit in 1832, ships continued to run aground on dangerous Dog Bar Reef, which extends shoreward from the point. Thus, the decision was made to build a breakwater over the ledge, which in addition to covering the reef provided sheltered waters in the harbor.
The Army Corps of Engineers built the 2,250-foot breakwater stretching out from Eastern Point Light between 1894 and 1905, as Congress doled out the requisite funds.
The substructure of the breakwater is a rubble mound covered with 231,756 tons of Cape Ann granite blocks, each one weighing 12-13 tons. The breakwater was constructed for $300,000 and is 7˝ feet above mean high water and ten feet wide.
On July 1, 1901, a fixed red lens lantern light was exhibited from an iron spindle surmounting a pile of riprap to mark the end of the unfinished breakwater, but a storm on November 5, 1901 damaged the spindle and carried away the lens lantern. As the post light was difficult to maintain, especially in winter, a gas buoy was placed off the end of the breakwater.
Before the breakwater was even completed, almost forty confused vessels had already crashed into it. One such ship, the schooner Carrie L. Hix, struck the breakwater and went to pieces on January 1, 1900. Two years later, on December 5, 1902, the schooner Flo F. Mader from Lunenberg, Nova Scotia suffered the same fate. Although that vessel was a total loss, all aboard were rescued by a crew from Dolliver’s Neck Lifesaving Station and then housed by Keeper George F. Bailey at Eastern Point Lighthouse.
After the breakwater was completed, an iron tower lighthouse with a first-class Daboll trumpet as a fog signal and a fourth-order light was recommended to mark the outer extremity of the granite blocks. The estimated cost of the proposed structure was $42,795. While waiting for Congress to appropriate the needed funds, a wooden tripod with a fixed white light, known as Gloucester Breakwater Light or Dog Bar Light, was established atop a granite mound at the end of the breakwater on December 4, 1905.
Keepers at Eastern Point Light were given the additional responsibility of caring for the new light. During calm weather the promenade provides a beautiful stroll to enjoy bird watching or fishing for flounder, pollock, or mackerel. However, when the weather turned foul, keepers risked being swept out to sea or slipping into the ocean from the ice coated granite blocks.
In 1910, the sum of $10,000 was requested from Congress for improving the light on the breakwater and adding a fog signal using the following language:
A great many fishing vessels frequent this harbor, entering and leaving at all times of day and night, and in all kinds of weather. The lens light now on the breakwater has not been adequate to prevent collisions with the breakwater. A more powerful light and a fog signal are needed.A white house and tower atop a square, skeleton substructure were soon built at the end of the breakwater, and on July 1, 1911, an electrically operated fog bell, one of just three used by the Lighthouse Service, was placed in operation.
An article in the Lighthouse Service Bulletin described the operation of the new bell:
The fog bell and its striker are located in a small house on the outer end of the jetty or breakwater. The descending weight employed to drive the striker is wound up by a small electric motor in the bell house; the motor is started automatically when the weight reaches the bottom of the fall, and is shut off when it reaches the top. The current is supplied to the motor over a pole line along the jetty from an electric generator driven by a petroleum engine, both of which are located in a small power house at the shore end of the jetty.
In early March 1931, a severe northeasterly gale swept the Massachusetts shore and caused considerable damage to lighthouse property. At Gloucester Breakwater, granite blocks were washed off the breakwater, breaking the cable that fed the light and fog bell, and the lighthouse structure itself was somewhat damaged. It wasn't water but rather fire that inflicted the most significant damage to the breakwater lighthouse. On February 17, 1943 a devastating fire destroyed nearly the entire fog bell house, but the structure was soon rebuilt.
After many years, the fog bell was replaced by electronic horns that formed a chorus with “Mother Ann’s Cow,” as the whistling buoy to the south is called.
Following automation of Eastern Point Light and Dog Bar Breakwater Light in 1985, a sensor that activates the electronic fog signal was placed at the end of the breakwater.
Today, Dog Bar Breakwater is part of a fifty-three-acre nature preserve owned by the Massachusetts Audubon Society. From sunup to sundown in good weather, the breakwater provides a marvelous location to view migrating waterfowl, seabirds, shorebirds, and monarch butterflies. Needless to say, when the weather turns foul and Mother Ann’s Cow cries out, the breakwater is closed to the public.
