Winter Storm Forces Salt Water Over Dam Into West Harbor Pond
A winter storm on January 13th, following on the heels of another storm only four days earlier brought severe flooding to the south-facing coastal areas of the Boothbay Region. Just after noon on January 13th, Mike Breen went down to the West Harbor Pond causeway to observe the effects of the storm. He arrived exactly at high tide, and what he witnessed was the combined effects of a king tide and the storm surge. Together, they brought the level of the harbor up to the very edge of the pavement on the causeway. In one of his photographs, you can see that seaweed has been washed onto the roadway. The videos show an enormous river of ocean water rushing into the Pond through the box culvert. The water gauge has lost one of its fastenings. Thanks to Mike for providing these photos and videos.
Statement on the Pond Grass in West Harbor Pond (July 21, 2023, edited August 20, 2023)
Many of you have noted with concern the abundant pond grass at the north end of the Pond and in patches elsewhere. We have contacted scientists at Bigelow who visited the Pond and indicated that although there is an excess of aquatic vegetation at the north end, this growth is actually helping to maintain a healthy balance in the Pond. They also indicated that it would be
ill-advised to remove the aquatic vegetation at this point because that could compromise the health of the lake. Native aquatic vegetation is essential for the health of the Pond. The pond grass is serving as a filter for excess nutrients entering the Pond in this unusually rainy summer, thus preventing more harmful species from taking over. It is also is providing shelter, food, and
nurseries for fish and other beneficial species.
Although the pond grass may be unattractive and may interfere with some recreational activities in some parts of the Pond, that does not mean that it is bad for the environment. In fact, in this case it appears to be preventing harm by taking up nutrients that otherwise could promote the growth of more harmful vegetation, including algae, particularly cyanobacteria which is
blooming in other lakes in the area, including Damariscotta Lake.
While this year’s growth of pond grass is unusual, this is not the first time that it has occurred. There may come a point when the pond grass grows to an unhealthy level, but we are nowhere near that in the Pond. It is patchy and generally limited to the shallow north end of the pond that receives the nutrient load from Campbell Creek and Knickerbocker Lake.
If the pond grass dies off suddenly and prematurely (that is, before fall), it may deoxygenate those parts of the pond where it decays. Signs to watch for are dead fish with swollen gills and scum forming on the surface of the pond. If the grass dies off in the fall, normal fall turnover will reoxygenate the water.
On August 20, 2023, the Pond Association took oxygen readings at two locations at the northernmost end of the pond and a third reading at the north end of Heron Cove. There was no sign that the dramatic disappearance of the pond grass in these three locations had resulted in deoxygenation of the affected areas. To the contrary, the oxygen saturation on the bottom of the Pond (about 3 meters/10 feet) was 82%, 79%, and 100.1% respectively at the three sampling locations.
Thanks to all of you who have inquired. We hope this satisfies your concerns and that you will be guided by the advice above.

The CMP Osprey Box

Recently Central Maine Power (CMP), at the suggestion of the WHPWA leadership, installed an Osprey box on a power pole on the Route 27 Causeway. For more information and photos, see: CMP installs osprey perch near West Harbor Pond | Boothbay Register.
Loons on the Pond
​
The summer of 2022 brought a loon couple to West Harbor Pond. They mated and produced a chick that spent the summer cruising the Pond with "mom and dad". They might be spotted in any area of the Pond, and often could be heard making themselves known at any hour of day--or night. By late summer the chick had grown to a teenager. We look forward to seeing how the family leaves the Pond in the fall, and to see if they return next year!
​
WHPWA member Lois Glaser took a number of wonderful photos of the family escorting the chick around the Pond. These can be viewed in gallery form on the page "Loon Family 2022". As many people know, most loons avoid the proximity of humans, and tend to keep their distance. These close up photos were possible for several reasons: Because WHP is small and boating activity is quiet (mostly kayaks and canoes) the loons seemed to gradually habituate to human presence. As a result, respectful paddlers could sometimes get a bit closer than expected, or the loons would show up nearby, to the surprise of the kayaker or canoeist! The photographer has a good DSLR camera with a 400mm telephoto lens, enabling her to zoom in on the loons from afar. Many images were also cropped, making the loons appear much closer than they were in reality.
In giving the loons the space they need, we are hopeful that the breeding pair will return again in 2023. We hope that all loons spotted on any body of water will be given this same respect.
