New Sensors Deployed as part of the Belgrade Lakes Gloeotrichia Monitoring Efforts

– Logan Parker, Director of Programming and Assistant Lake Science Manager

Promptly at 9:00 AM Monday morning (July 24th), a number of sensors deployed around Great Pond and Long Pond began a 2-month long, in situ data collection effort. These 15 HOBO sensors are gathering temperature and light data at the observation sites where volunteers around the lakes have been collecting gloeotrichia observation data.

Gloeotrichia is a cyanobacteria (formally referred to as Blue-green Algae) that occurs in many lakes throughout New England. These organisms have the means to control their buoyancy, residing on the lake sediments for much of the year before rising en masse to be distributed throughout the lake’s surface waters by the currents. Collecting temperature data will give us more insights about the environmental conditions that coincide with the bloom events that have become increasingly numerous in recent decades.

These sensors will remain in place hanging below the ends of docks in places including Hatch Cove, Hoyt Island, Pine Island, and Long Point in Great Pond and Beaver Cove, Bonzos Hollow, and Tracy Cove in Long Pond.

A new observation station was established in Great Pond’s North Bay where Great Meadow Stream flows into the lake. This site is being stewarded by the Belgrade Region Conservation Alliance’s Milfoil crew who work in the stream and the bay regularly throughout the season. Anecdotal reports state that gloeotrichia can be abundant in this area throughout late summer, so we are grateful to have the milfoil team’s support! Students on the MLRC’s water quality research team continue to collect observation data at the DEP sampling sites throughout the watershed.

We would like to issue a special thanks to the Belgrade Lakes Association for sponsoring this research effort by providing our program with these new sensors.

 

Role changes at the MLRC

The Maine Lakes Resource Center (MLRC), home of several local environmental groups, announces the appointment of Brenda Fekete as Interim Executive Director/Lake Science Manager.  Ms. Fekete has served as Lake Science Manager for the last two years, working with Colby College faculty and student interns on collecting data from all of the lakes in the Belgrade Lakes Watershed and analyzing the data at the Colby College facilities and in the Colby wet lab at the MLRC. She will continue as Lake Science Manager and Interim Executive Director with the help of Logan Parker, whose responsibilities have expanded to Director of Programming/Assistant Lake Science Manager.

The Maine Lakes Resource center is organizing and adjusting staffing to meet anticipated needs and challenges of the future.  The organization has retained a development consultant and plans to hire a permanent executive director.  Kathi Wall, former administrator of the MLRC, has elected to step down her level of involvement.  She developed parallel programming around the intersections of science and the arts at the MLRC Annex. The Annex, which was an extension of the MLRC located in a separate building adjacent to the Belgrade Lakes Post Office, will now be operated separately by Kathi Wall as a creative center.

Water Quality Update – November 2016

The beautiful and unseasonably warm fall has allowed us to sample two weeks longer than last year, but it is time to call it a season and bring in the boats! Although only the deeper sites in Long Pond and Messalonskee Lake have not experienced fall turnover, we have collected our final water profile, grab sample, and secchi reading from each of the ten sampling sites. We have also finished the sediment sampling on all of the seven lakes. A big thank you to the volunteers that braved the colder fall weather. We could not have finished our sampling effort without you! Due to the lack of ice, were unable to collect winter samples last year. We are crossing our fingers and hoping to get the snowmobiles out this year!

larchinserpThe off season will be very busy with water and sediment sample analysis (at Colby), data analysis, comparison of 2015-16 data, lake remediation meetings and logistics for winter and spring sampling. Stay tuned for another community update meeting in the spring!

Goldie was removed from Great Pond on November 7th. She will be cleaned up and on display in the MLRC gallery throughout the winter season. The Goldie website is a great place to find a summary of the data that she collected from May through early November.

Another place to find the water profile data collected from May through November is right here on MLRC website. I have recently posted the final data set for each of the seven lakes. I have displayed the data in a fall season profile to make the progression towards lake turnover easier to see. The Interactive map also displays the most recent data for each of the sampling sites.

The FlowCam will remain in the Colby Water Analysis Lab at the MLRC and will continue to be used for phytoplankton analysis by the research team. Feel free to stop in and look at the awesome pictures if you happen to be in the gallery while we are working!

It was great seeing new and familiar faces at the October Water Quality Community Meeting. The Colby Capstone students will be presenting their exciting lake data on December 6 at 1pm in the MLRC gallery. Hope to see you then!

_dsc6147Very bittersweet… the colder temperatures required lots of layered clothing, but the beautiful fall colors and lake wildlife that was enjoyed while sampling will be missed! It was a great 2016 season!

Wishing everyone a wonderful holiday season! Bring on the snow!
