Lakes Conference: Lakes at the Edge
The annual lakes conference theme Lakes at the Edge can be interpreted many ways. Many of our lakes are on the edge of rapidly deteriorating health. They are at the tipping point where just a little more phosphorus in the water will tip them toward recurring algal blooms. Many are at the edge of the carrying capacity for development in their watersheds, where runoff from poorly managed roads, roofs and driveways may push their health to, or over, the edge. And of course much of lake conservation work takes place at the literal lake edge. What can we do in the shoreland zone and surrounding uplands of our lakes that keeps them healthy?

Jeremy Deeds
Biography
Jeremy Deeds has been an aquatic ecologist with the Maine Department of Environmental Protection since 2014. Prior to that, he worked with the Lakes and Ponds Section of the Vermont Department of Environmental Conservation. He has worked on many aspects of water quality and ecological condition, including lake condition assessments, biological community classification, data modeling, and littoral habitat evaluations. He holds an M.S. in Aquatic Ecology from Kent State University and a Ph.D. in Ecology and Environmental Science from the University of Maine.
Living on the Edge: Shallow-Water Habitat Condition in Maine Lakes
The shallow areas of lakes contain habitats that are critical to all lake life. The conversion of lakeshores to developed land – houses, roads, lawns, etc. – can diminish the quality of this habitat when the shoreland is not managed properly. Biologists at the Maine DEP have been studying the relationship between lakeshore development and the quality of shallow water habitat to better understand this linkage, and consequently make better decisions about where shoreland rehabilitation efforts are needed most. This presentation will show how these measurements are performed, what we are learning about lake habitat, and what these surveys mean for the future of lake protection in Maine.

The Impacts of Terrestrial Invasive Plants on Riparian Forests & Watershed Ecosystem Services
Non-native invasive species are a major cause of ecosystem degradation and impairment of ecosystem service benefits. Riparian areas are at high risk for invasion because they are among the most human-disturbed ecosystems in the world. Forested riparian areas provide us with many ecosystem services and are vital to streams, rivers, and lakes as they increase habitat complexity and available resources for organisms of many trophic levels. In this talk, we will discuss the impacts of terrestrial invasive plants on riparian forests, soil structure, soil functioning, stream physical habitat, and watershed function.

Visualizing Internal Phosphorus Release from Lake Sediments Using Volunteer-Collected Data
Many Maine lakes, including some of the most bloom-prone on the Maine DEP’s list of “Impaired” lakes and 32 lakes on the “Threatened” lakes lists, are highly sensitive to internal phosphorus (P) release from bottom sediments. While most volunteer monitors aren’t trained to collect water column P data, some watershed groups have taken on this task to better understand internal P loading and its link to summer algal blooms. This presentation provides an overview of monitoring methods and types of data needed to create P mass graphs using volunteer-collected data, and how to interpret the graphs. These results can be used to calculate the mass of P in a lake, gain a better understanding of the role of internal (sediments) vs. external (watershed) P loading during different times of the year, and visualize the lake’s response to environmental factors such as precipitation. Examples will include graphical representations of internal loading from a variety of lakes across the state ranging from shallow unstratified or ephemerally stratified lakes, to deep stratified lakes.

Our Shore: The Nature-based Shoreline Stabilization Toolkit
Over the last few years, the Maine Department of Environmental Protection and Maine Climate and Science Information Exchange at the University of Maine have been partnering with natural resource agency staff, university faculty, municipal officials, and design professionals to develop “O.U.R. S.H.O.R.E”. OUR SHORE is intended to provide guidance and training for using nature-based tools to protect against shoreline erosion, while preserving and restoring natural functions to these important areas. OUR SHORE is a method of comparing options for shoreline stabilization so landowners, contractors, designers, and others can customize solutions for shoreline erosion in a manner that preserves or improves shoreline habitat, functions, and long-term resilience. The OUR SHORE approach relies on targeting the contributing sources of erosion and instability to select and combine tools that will address these causes using the least intervention necessary while using natural, biodegradable or living materials. The guidance provides techniques and considerations to include habitat and shoreline functions into the design of any project, even when riprap is used, so the outcome over time is a naturalized and more resilient shoreline.

Building eDNA Applications for Invasive Aquatic Species Detection to Supplement Monitoring Programs
This presentation will cover the basic concepts, advantages, and shortcomings of eDNA before addressing specific areas of lake management that can benefit from eDNA tools.
Environmental DNA (eDNA) is genetic material left by organisms in their environment. In recent decades eDNA technology has advanced in its abilities to detect algae, zooplankton, fish, and plants in aquatic systems. eDNA applications are best used when paired with existing survey methods as it is a growing field. Numerous side-by-side (eDNA to traditional survey) comparisons have demonstrated strong overlap in species identification for fish and zooplankton and often eDNA detects more species than identified using traditional survey methods alone. For lakes and ponds that do not have established monitoring programs, eDNA may provide an easy and effective way to survey these underserved areas. One of the remaining limiting factors for eDNA applications is the need for accurate and accessible DNA sequencing from verified specimens (i.e. DNA library) to verify DNA sequences from environmental samples. Some groups of organisms (freshwater fish and eukaryotic algae) have decent coverage of DNA sequences in open source libraries while other organisms such as aquatic plants have limited DNA sequences verified sources available. In 2023, 7 Lakes and partners (Bigelow Laboratory, Lake & Watershed Associates, lake associations) launched an ambitious effort to collect voucher specimens of all aquatic plant species (native and invasive) found in Maine to build an accessible, accurate, and trustworthy eDNA library for aquatic plant surveys. The library is slowly building! All lovers of lakes and aquatic plant enthusiasts are welcome to join in on the effort.
