West Harbor Pond was created in 1880 when a dam was constructed across the mouth of Campbell Cove where it enters Boothbay Harbor. The goal was to impound fresh water flowing from Campbell Stream in order to develop a commercial ice business. The new company was intended to provide off-season employment for the community's workers by producing natural ice for sale to the large urban centers of the Eastern Seaboard. A road constructed along the top of the dam eventually became State Route 27.  


Sea water trapped behind the dam was removed by a large, passive siphon, which subsequently served to remove any sea water that might seep through the dam or enter through the box culvert at its west end. So far as is known, it is the only one in the state of Maine. Any salt water that enters the Pond sinks to the bottom because of its greater density. As the tide receded on the Harbor side of the dam, the siphon, whose intake was at the 15' level, would draw this salt water from the Pond and return it to the Harbor. Above the 15' level then was fresh water that turned over seasonally, re-oxygenating the Pond to the 15' level and maintaining its aquatic health to that depth.


In 2008, after 130 years of maintaining the Pond's water quality, the siphon failed and the salt water layer in the bottom of the Pond rose above the 15' level. This salt water layer did not turn over seasonally, was entirely de-oxygenated, and could no longer sustain aquatic life. In March 2019, after a successful fund-raising campaign that was strongly supported by the entire community, the WHPWA replaced the old, failed siphon, and the new siphon, whose intake is now at the 24' level, has been responsible for a dramatic improvement in the Pond’s water quality compared with that of the years from 1880 to 2018.  For much more about the siphon, go to our siphon page.
