Annual Lake Monitoring Conference Archives

2019 Lake Monitoring Conference

LSM’s 2019 Annual Lake Monitoring Conference was held on July 27th at The Great Outdoors on Pleasant Pond in Turner, and explored the impacts of climate change to lakes. Lake scientists, as well as individuals from lake communities who have experienced climate-driven ecological catastrophes in their lakes were present to discuss their experiences. When all factors are taken into account, climate change is almost certainly the greatest, and most complex known threat to the health of Maine’s lakes! This phenomenon has the potential to amplify the effects of polluted stormwater runoff and watershed erosion, severe, and potentially toxic algal blooms, the threat of invasive aquatic species, habitat impairment, drought, and much more.

2019 Program:

Maine Lake Ice-Out Dates: 1807-2018
Lloyd Irland, PhD; Forester and Economist; The Irland Group

View Presentation Slides

Maine’s exceptional lakes are clear and clean, due in no small part to the fact that historically they have been covered with ice and snow for nearly 6 months of the year. A shortening of the duration of ice cover on lakes as a result of a warming climate will likely have a profound effect on the interacting biogeochemical factors that influence lake ecosystems. Lloyd Irland will discuss his recent research, which suggests that a shortening of the period of ice cover on Maine’s lakes has been taking place since the mid 19th century.

The Influences of Climate Change on Lake Water Quality, Including Recent Case Histories
Linda Bacon, Limnologist and Unit Leader; Maine Department of Environmental Protection, Lakes Program

View Presentation Slides

During the past 10-15 years, a number of Maine lakes have experienced significant, unanticipated changes in water quality. A warming climate appears to have been a common factor in the complex interaction of conditions and circumstances that contributed to these changes. Linda Bacon will discuss the case histories of several lakes that have been pushed “over the edge” in recent years, as well as efforts underway to slow or reverse their decline.

The Effects of a Changing Climate on Invasive Aquatic Species: Threats to Maine’s Lakes
Roberta Hill, Aquatic Ecologist and Invasive Aquatic Species Program Director; Lake Stewards of Maine

View Presentation Slides

One of the major historical factors that has protected Maine’s lakes from aquatic invaders has been our relatively cool climate. Many species of invasive flora and fauna that have successfully infested lakes throughout much of the Country have failed to gain a foothold in Maine, in part due to our long, cold winters, and cool water temperatures. A warming climate could open the door to many such invaders. Roberta Hill will discuss what could take place in such a scenario, and what can be done to address the problem and reduce this threat.

The Imminent Launch of the Long-Awaited App: A Field Guide to Aquatic Phenomena; Demonstration of, and Discussion of the App Development
Spencer Harriman, Logistics & IT Manager, and App Coordinator; Lake Stewards of Maine

View Presentation Slides

Every lake in Maine is a place of wonder and discovery. The LSM Field Guide to Aquatic Phenomena has been developed to not only provide a knowledgeable mobile-device based companion for lake-bound adventurers; but also, to engage lake users in the important work of spotting threats to lakes as early as possible. Version 1.0 of the app focuses on common and/or potentially problematic phenomena that people might encounter when out on their lake. Once launched, the initial catalog of species and images will be updated and enhanced regularly. Best of all, the app has been specifically designed to encourage users to play an active role in the ongoing development of this infinitely expandable resource.

LSM’s Spencer Harriman will share on screen Maine’s newest lake app, discussing LSM’s fruitful collaboration with ASAP (University of Maine student app developers); and demonstrating how easy it is to search a wide array of FAUNA, FLORA and OTHER LAKE PHENOMENA, zeroing in on the phenomena of interest through a series of simple keys. He will also provide a preview of some of the additional features and functions that are already in the pipeline.

A beta version of the new app be previewed at this year’s LSM Lake Monitoring Conference. Those who would like to help test the beta version, may sign up in the exhibit hall.

2017 Lake Monitoring Conference Program

Morning Session:

  • The Cyanobacteria Monitoring Collaborative: An Approach to Educating the Public About Monitoring, and Managing Harmful Cyanobacteria; Dr. Jim Haney, Professor, Department of Biological Sciences,  University of New Hampshire

Harmful algal blooms (HAB’s), caused by cyanobacteria, pose an increasingly significant risk to the health of our lakes, and to those who spend time on, and in them. Citizen lake scientists (volunteer lake monitors) can play an important role in the detection of HAB’s, allowing us to better understand causative factors, and ways to prevent them.

  • Maine’s Lake Plants ~ How Citizen Lake Scientists Are Enhancing Our Understanding of Native Macrophyte Communities; Roberta Hill, Invasive Species Program Director, Maine VLMP

Maine has some of the richest, most abundant freshwater littoral habitat on earth. The VLMP’s Invasive Plant Patrol Program supports the work of hundreds of citizen lake scientists who are helping to answer the many questions that have arisen regarding both native (and invasive) plants in Maine’s lakes.

  • Citizen Lake Stewardship and Beyonce’s “I Was Here!”: Finding Our Groove For Maximum Lake Resilience In The Face Of Growing Environmental Impacts; Adam Zemans, Outreach & Stewardship Coordinator, Maine VLMP

In the award-winning documentary, The Hunt for Aquatic Invaders, which was produced, directed and filmed by Steve Underwood, Maine VLMP citizen lake steward, Elin Haugen, described the reason for the Maine VLMP’s mission: “This lake is like a gemstone. It’s like the Hope Diamond of lakes here in Maine, and when I come over Indian Hill, it takes my breath away! And Moosehead Lake has so many sensory delights that create memories.” Many of us feel similarly about our own Maine lakes. What does lake stewardship mean to you? What does lake stewardship mean about you? And, when it comes to Maine Lakes, what legacy do you contribute?  The answer is: more than you might imagine.

  • Lake Shoreline and Littoral Zone Conditions as an Indicator of Overall Lake Health: Current Efforts in Maine lakes, and the Future Potential for Citizen Scientists to Participate in this Assessment; Doug Suitor, Biologist, Maine DEP

A significant finding of the National Lakes Assessment (NLA) was that there is a correlation between the disturbance of lake shoreline and littoral areas, and overall lake health. Maine DEP biologists are contributing to this finding through the gathering of additional littoral and shoreline data on lakes throughout Maine. Citizen lake scientists may play an increasingly important role in this assessment in the future.

  • Metaphyton (aka: “green cotton candy) in Your Lake: What Do We Know? What Don’t We Know? Has There Been an Increase of this Algae in Maine Lakes in Recent Years?; Scott Williams, Executive Director, Maine VLMP

In recent years, there has been much discussion and speculation concerning a possible overall increase in  the abundance of metaphyton in Maine lakes. But most of the available information is based on observation, and little can be said with certainty about this often unwelcome lake dweller.  A few shallow ponds have experienced dramatic metaphyton blooms that have encompassed the entire body of water. What might be causing such changes, and what can be done to reduce the risk of blooms, or to control them?

    • Honoring Maine VLMP’s Remarkable Lake Monitors

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Afternoon Workshops:

      • The US EPA mobile lab for monitoring cyanobacteria will be set up at the conference, so that people can see and experience how trainings can be given to interested parties at on site locations.  Workstations will be set up in the mobile lab to demonstrate the preparation of cyanobacteria for identification and data collection purposes along with experiencing the use of fluorometric tools for quantification of cyanobacteria in the water.


      • Water Quality Monitor Re-Certification Workshop: Certified lake water quality monitors that need to be re-certified may do so at the annual conference.  Pre-registration is required, so please contact the VLMP at or (207) 783-7733 to reserve your spot.

Monitoring Maine Lake Temperatures with Hobo Data Loggers: Greater Understanding through Technology

Dr. Dan Buckley, Professor of Biology at the University of Maine Farmington will present findings from research that he has spearheaded in recent years concerning the nature of thermal stratification (temperature layers) in our lakes. With the help of many VLMP lake monitors, Dan has observed that this common phenomenon that plays a critical role in the function of lake systems may be more complex than previously thought, especially in light of extreme weather events associated with climate change.

Identifying Aquatic Plants in Maine: What’s New?

Dr. C. Barre Hellquist, Professor Emeritus of Biology at Massachusetts College of Liberal Arts, and one of the world’s foremost authorities on aquatic plants, will discuss “What’s New” in the ever shifting world of aquatic plants. Some aquatic plants are easily identified.  Others are trickier.  Some may actually require DNA analysis to identify with certainty.  Barre will walk us through the newest information pertaining to aquatic plant identification, focusing upon plants that Maine’s invasive plant patrollers are likely to encounter.  He will also show us some new invasive aquatic plants that should be on our radar screens.

Phosphorus in lakes – The old paradigm, a paradigm shift, and the future

Dr. Steve Norton, University of Maine Professor Emeritus, will discuss the complex ways in which phosphorus influences Maine’s lakes, including the implications of his research on the geochemistry of lake sediments. He will also describe a unique collaborative pilot project involving University of Maine social science faculty and graduate students, Maine DEP and VLMP staff, and a group of VLMP certified lake monitors who will receive hands-on training and experience in collecting lake sediment samples from their lakes. The results of this project will be used to update an index of vulnerability that will be used to help determine the degree to which individual lakes are susceptible to a decline in water quality over time.

Climate Change & Maine Lakes: Observations and Expectations

Click on image for presentation in PDF format. File may take a few moments to load.

“Climate change” is a term relatively new to our vocabulary, with several tumultuous storms presenting challenges to Maine and the Northeast over the past year. So how are these changes affecting Maine’s lakes? This presentation will touch on a variety of observations – some documented in the lakes literature, others anecdotal – with a ‘take home’ message of prevention and preparation being one of the few actions we can take to face the challenges ahead.

Our Speaker – Linda Bacon has worked in the Lakes Section of the Department of Environmental Protection for the past 24 years and prior to that, in acid rain research at the University of Maine in Orono for four years. She is the Quality Assurance liaison to the VLMP and is an ‘ex officio’ member of the VLMP Board of Directors. Linda received her Master’s degree from the University concentrating in aquatic ecology in 1987 and is currently working on her PhD.

Integrating Citizen Science and Satellite-Based Remote Sensing for Monitoring of Maine’s Lakes

Click on image for presentation in PDF format. File may take a few moments to load.

It is now possible to use satellite imagery to monitor the water quality of Maine’s lakes. By measuring the relationship between field-collected Secchi disk data and satellite-measured reflectance, we can then estimate the Secchi depth of unsampled lakes, many of which are inaccessible and difficult to monitor in the field. Volunteer lake monitors play a very important role in the process of calibrating satellite imagery lake data. Please click here for Landsat 5 and Landsat 7 information.

Our Speaker – Ian McCullough finished his Master’s in Ecology and Environmental Science at the University of Maine in May, 2012. He collaborated with Maine DEP on developing a satellite-based remote lake monitoring program for Maine, utilizing VLMP-gathered historical lake data throughout the process. He graduated with a BA in Environmental Studies in 2010 from Colby College, where he participated in long-term research on land use, residential development and phosphorus cycling in the Belgrade Lakes system. Ian is originally from McLean, Virginia and is beginning a doctoral program at the University of California-Santa Barbara this fall.

Feathered Fish! Loon Research & Conservation

Click on image for presentation in PDF format. File may take a few moments to load.

Over the last 25 years, Biodiversity Research Institute has banded over 3,000 Common Loons across North America. All that hard work banding loons has paid off because we have made a lot of new discoveries about loons. Jim will share some of those insights and in addition, will talk about some conservation efforts the Center for Loon Conservation at Biodiversity Research Institute is involved with across North America.

Our Speaker – Jim Paruk is a passionate naturalist, equally at home identifying birds, butterflies and wildflowers. He has travelled extensively throughout North and Central America, and for the past 20 years has conducted research on loons from one side of the continent to the other. His doctorate examined Common Loon social and breeding behaviors. He has personally watched and recorded over 4,000 hours of observations on Common Loons. He served as Vice-President of the North American Loon Fund and Research Chair for Wisconsin’s Loonwatch Program. He was a tenured, full-time college professor for 14 years teaching Ornithology, Ecology and Animal Behavior at both Feather River College (CA) and Northland College (WI) before taking this new position as the Director of the Center for Loon Conservation, at BioDiversity Research Institute. Jim is considered an expert on Common Loon behavior and ecology and was the co-author of the Common Loon species account published by the Birds of North America in 2010. Presently, he is an Adjunct Professor of Biology at University of Southern Maine teaching Ornithology.

2011 Conference Highlights

Our Mission

The Mission of the Lake Stewards of Maine (LSM) is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. LSM trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, LSM volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities.


LSM is a non-profit 501(c)(3) organization committed to the collection of information pertaining to lake water quality. For 50 years, trained volunteers throughout Maine have donated their time so that we may all learn more about one of Maine’s most beautiful and important resources — our lakes.
