Plant Survey at Highland  Lake

Field work for the lake plant survey for Highland Lake was completed on July 19. Dennis Roberge of Lake Stewards of Maine Invasive Plant Patrol, Prof. Karen Wilson's students Paige Mallory, Sarah, and Alayna, assisted. It took nearly 100 people hours over eleven days. We found none of the notorious invasive lake plants such as Eurasian water-milfoil or Hydrilla, but we did note for the first time Nightshade (Bittersweet) (scientific name Solanum dulcamara) intruding into the stream channel water at the north end of the lake. I understand from local gardeners that it is widespread in the wild. Over a quarter century time, I have identified nearly one hundred different species. Until I finish the data analysis, probably late this winter, I won't know the species count for this year, and more importantly, what changes happen over time.

HLA Annual Meeting July 18, 2019

Keynote speaker Dr. Karen Wilson updates the membership on the status of Highland Lake's water quality. To view a summary of the meeting click here.

The Highland Lake Association (HLA) is a registered 501(3)(c) non-profit organization, started in 1989. Our organization is staffed by volunteers from around the lake and is supported by our member dues. Our mission is to preserve, enhance, and protect the natural resources of Highland Lake and its watershed. The HLA has established itself as a leader in watershed education and water quality monitoring.  Protecting water quality remains our top priority. The HLA Water Quality Committee monitors lake water quality using recognized standard methods, including analysis of natural and invasive plant species and coordinates additional testing, education, and personnel as warranted. We collaborate with our local partners, the Cumberland County Soil and Water Conservation District, the Towns of Windham, Falmouth and Westbrook as well as USM, UNH and the DEP to improve and maintain the water quality of Highland Lake for the benefit of the residents, the Towns and future generations. The first summer camps appeared around 1900 on Highland Lake, a lake less than 12 miles from Portland, Maine. There are now more than 500 residences around the lake shore and more than 1000 within the watershed. The area around the dam (Duck Pond corner) served as the industrial center to residential settlement dating back to the late 1700s. The site served as a rag mill as well as a lumber mill. HLA is proud to maintain the lake’s history and dedication to pure enjoyment in pure water!  HLA welcomes residents along the shoreline and beyond to join in our efforts to keep Highland Lake at its best.

Thank you to Julia Ellsworth for allowing us to use some of her beautiful photographs, of the northern side of Highland Lake, throughout our website.


HLA is excited to announce the launch of our new Facebook page.  Join us on Facebook and get to know your lakeside community.  Post a photo, make a comment, keep in touch with your neighbors. Like us on Facebook at https://www.facebook.com/highlandlakemaine.org/
