In response, lakes have exhibited shifts in physical and biological conditions, creating challenges for supporting lake resilience at levels from the individual lake to the landscape. Emerging patterns include shifts in phenology, geochemistry, and lake productivity, and associated challenges include evaluating cyanotoxin hazards, emerging contaminants, and economics of water clarity. Variation in response and resilience across lakes highlights the importance of comprehensive research and monitoring in developing a landscape-wide perspective on lake ecosystem change. This session will allow researchers and lake watershed managers to share recent work, especially related to evaluating regional and local drivers across a range of lake types.<\/p>\n\n\n\n<p><strong>Session Schedule<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/umaine.edu\/mitchellcenter\/2024-maine-sustainability-water-conference-old\/maine-lake-resilience-and-response-to-regional-and-local-stressors\/#s10p1\"><strong>1:30PM-1:45PM<\/strong>\u00a0\u2013\u00a0<em>Adaptation to Elevated Sea Salt Levels in Sewall Pond | Presenter: Mary Rogalski<\/em><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/umaine.edu\/mitchellcenter\/2024-maine-sustainability-water-conference-old\/maine-lake-resilience-and-response-to-regional-and-local-stressors\/#s10p2\"><strong>1:45PM-2:00PM<\/strong> \u2013 <em>Shifting Seasonality: Consequences of the Changing Autumn Season for Maine\u2019s Ecologically and Recreationally Valuable Mountain Ponds <\/em><em>| Presenter: Amanda Gavin<\/em><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/umaine.edu\/mitchellcenter\/2024-maine-sustainability-water-conference-old\/maine-lake-resilience-and-response-to-regional-and-local-stressors\/#s10p3\"><strong>2:00PM-2:15PM<\/strong>\u00a0\u2013 <em>The Distribution of Toxic Planktothrix Strains Across Maine <\/em>|<em> Presenter: Robin Sleith<\/em><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/umaine.edu\/mitchellcenter\/2024-maine-sustainability-water-conference-old\/maine-lake-resilience-and-response-to-regional-and-local-stressors\/#s10p4\"><strong>2:15PM-2:30PM<\/strong> \u2013 <em>Assessing Need and Feasibility of Bacterial Monitoring at Freshwater Beaches in Maine<\/em>|<em> Presenter: Margo Kenyon (student)<\/em><\/a><\/li>\n\n\n\n<li><strong>2:30PM-3:00PM<\/strong> \u2013 Afternoon Break<\/li>\n\n\n\n<li><a href=\"https:\/\/umaine.edu\/mitchellcenter\/2024-maine-sustainability-water-conference-old\/maine-lake-resilience-and-response-to-regional-and-local-stressors\/#s10p5\"><strong>3:00PM-3:20PM<\/strong> \u2013 <em>Building Resilience in Acadia National Park\u2019s Lakes: A 45-Year Journey<\/em>|<em> Presenter: William Gawley<\/em><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/umaine.edu\/mitchellcenter\/2024-maine-sustainability-water-conference-old\/maine-lake-resilience-and-response-to-regional-and-local-stressors\/#s10p6\"><strong>3:20PM-3:40PM<\/strong> \u2013 <em>Impacts of Intense and Above-Normal Summer Precipitation on Lake Conditions and Trends<\/em>|<em> Presenter: Ben Peierls<\/em><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/umaine.edu\/mitchellcenter\/2024-maine-sustainability-water-conference-old\/maine-lake-resilience-and-response-to-regional-and-local-stressors\/#s10p7\"><strong>3:40PM-4:00PM<\/strong> \u2013 <em>Valuing the Economic Benefits of Maine\u2019s Lakes and Great Ponds in the 21st Century<\/em>|<em> Presenter: Jianheng Zhao<\/em><\/a><\/li>\n<\/ul>\n\n\n\n<p><strong>1:30PM-1:45PM<\/strong><\/p>\n\n\n\n<p><em>Adaptation to Elevated Sea Salt Levels in Sewall Pond<\/em><\/p>\n\n\n\n<p><strong><a href=\"mailto:mrogalsk@bowdoin.edu\">Mary Rogalski<\/a><\/strong> (1), <a href=\"mailto:ochambers@bowdoin.edu\">Owen Chambers<\/a> (2), Sophie Burchell (2), <a href=\"mailto:bnichols@bowdoin.edu\">Brady Nichols<\/a> (2), <a href=\"mailto:kkulzy@bowdoin.edu\">Kayla Kulzy<\/a> (2)<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Biology and Environmental Studies, Bowdoin College\u00a0<\/li>\n\n\n\n<li>Bowdoin College<\/li>\n<\/ol>\n\n\n\n<p>Maine lakes tend to be ion-poor due to the regional geology, but those near the coast may receive added salt from sea spray or tidal influence. Sewall Pond in Arrowsic, ME is one of the highest salinity lakes regularly monitored by the Maine Department of Environmental Protection (DEP). Data collected by DEP, volunteer monitors, and our lab indicate that salt levels have increased in Sewall Pond after the outflow culvert was modified in 2014 to improve migratory alewife passage. In fall of 2022, Sewell Pond reached a conductivity of 1080 uS\/cm, after fluctuating between around 200-600 uS\/cm the previous several years and staying around 150-250 uS\/cm between 1980-2013. How do these changing salinity conditions affect resident organisms? Experiments working with <em>Daphnia<\/em>, microscopic crustaceans living in lakes and ponds, show that Sewall Pond water is supportive of their growth and reproduction, even for populations from relatively low ion lakes; however, the high salinity conditions observed in October 2022 were stressful for <em>Daphnia<\/em> from the low-ion lakes. Interestingly, <em>Daphnia<\/em> collected from Sewall Pond during high salt conditions appear to be better adapted to handle this salt toxicity relative to those collected during a lower salinity time period. This supports that <em>Daphnia<\/em> in Maine lakes can adapt to their local lake water chemistry; conditions that might exert stress, such as very low or high salt conditions, may be less stressful or even beneficial for resident populations. Evolution may even be happening from one year to the next!<\/p>\n\n\n\n<p><strong>1:45PM-2:00PM<\/strong><\/p>\n\n\n\n<p><em>Shifting Seasonality: Consequences of the Changing Autumn Season for Maine\u2019s Ecologically and Recreationally Valuable Mountain Ponds<\/em><\/p>\n\n\n\n<p><strong><a href=\"mailto:amanda.gavin@maine.edu\">Amanda Gavin<\/a><\/strong> (1) (student), Jasmine Saros (1,2,3), Sean Birkel (2), Julia Daly (4), Rachel Hovel (4), Sarah Nelson (5)<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>91爆料 Ecology and Environmental Sciences\u00a0<\/li>\n\n\n\n<li>91爆料 Climate Change Institute<\/li>\n\n\n\n<li>91爆料 School of Biology and Ecology<\/li>\n\n\n\n<li>91爆料 Farmington<\/li>\n\n\n\n<li>Appalachian Mountain Club<\/li>\n<\/ol>\n\n\n\n<p>Mountain ponds are susceptible to regional and global environmental change and are recreational hotspots that contribute to Maine\u2019s tourism economy; however, the impact of climate change on the water quality and recreational value of these ponds remain unclear. In Maine\u2019s mountain region, the most notable warming trends have occurred in the winter and fall. Warming in these seasons could affect two key physical processes that influence lake ecology: ice-on and water column mixing. This project focuses on nine mountain ponds in Maine that are representative of important high-elevation habitats and are recreationally significant, as they provide critical water sources for hikers and are backcountry fishing destinations. The conservation status of these ponds varies from no current protections to protection of the full watershed within conserved mountain ranges or ecological reserves. The goal of this project is to identify trends in autumn mixing and ice-on, inferred through long-term temperature monitoring and a new community science initiative, and integrate these results with a gap analysis of conservation status across mountain pond watersheds to identify how conservation interacts with climate change impacts in mountain ecosystems. We will present results from mixing and ice-on trends analyses, community science ice-on observations, and the conservation gap analysis. Together, the interdisciplinary nature of this research quantifies mountain lake vulnerability to climate change and applies these results to identified conservation gaps to develop a solution-oriented framework for future mountain pond management.<\/p>\n\n\n\n<p><strong>2:00PM-2:15PM<\/strong><\/p>\n\n\n\n<p><em>The Distribution of Toxic <\/em><em>Planktothrix<\/em><em> Strains Across Maine<\/em><\/p>\n\n\n\n<p><strong><a href=\"mailto:rsleith@bigelow.org\">Robin Sleith<\/a><\/strong> (1), Linda Bacon (2), Peter Countway (3)<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Bigelow Laboratory for Ocean Sciences\u00a0<\/li>\n\n\n\n<li>Maine Department of Environmental Protection<\/li>\n\n\n\n<li>Bigelow Laboratory for Ocean Sciences<\/li>\n<\/ol>\n\n\n\n<p>Climate change and nutrient pollution in freshwater ecosystems have led to the increase in frequency of harmful cyanobacterial blooms.

Today, warmer water in our lakes and ponds can create conditions that allow more harmful pathogens to persist and multiply. That threat is poised to grow in the future as the climate warms and as more residents and visitors seek out local freshwater swimming areas to escape the growing heat. More people crowding into small, still freshwater swim locations has the potential to increase the prevalence of disease-causing pathogens in the water and threaten public health. A recent project by Maine Lakes, Lake Stewards of Maine, and the Maine Department of Environmental Protection investigated the feasibility of and interest in developing a bacteria monitoring program for freshwater swim areas. Project staff surveyed stakeholders to gauge awareness of and interest in bacterial monitoring programs, and built an extensive database of freshwater swim areas in Maine including ownership, size, and other features relevant to potential monitoring activities. These criteria were then examined using environmental justice criteria to help identify priority focus areas for a potential bacterial monitoring program. Results of this important investigative effort will be shared and underscore the interest in, need for, and challenges ahead for a statewide freshwater bacteria monitoring program in Maine.<\/p>\n\n\n\n<p><strong>2:30PM-3:00PM<\/strong><\/p>\n\n\n\n<p><em>Afternoon Break (Auditorium)<\/em><\/p>\n\n\n\n<p><strong>3:00PM-3:20PM<\/strong><\/p>\n\n\n\n<p><em>Building Resilience in Acadia National Park\u2019s Lakes: A 45-Year Journey<\/em><\/p>\n\n\n\n<p><strong><a href=\"mailto:bill_gawley@nps.gov\">William Gawley<\/a><\/strong> (1), Rachel Fowler (2), Kathleen Brown (1)<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>National Park Service, Acadia National Park<\/li>\n\n\n\n<li>91爆料<\/li>\n<\/ol>\n\n\n\n<p>Acadia National Park has long been a valued site for monitoring and research studies to determine the effects of acid deposition, mercury contamination, nutrient enrichment, climate change, human impacts, and other stressors on the parks iconic and largely pristine lakes.

Many threats, including air pollution and climate change, are less manageable at the local level, but park studies contribute to the greater body of scientific and outreach efforts working to address these problems at the national and global level. All these accomplishments were made possible through long-standing and ongoing collaborations with federal, state, local, and academic partners.

Increased precipitation has the potential to affect lake trophic state through increased nutrient, organic matter, and sediment loading, depending on lake and watershed characteristics. High rainfall rates may have an even greater impact through significant watershed erosion. Parts of Maine experienced frequent and often intense rain events during 2023 making it the second wettest summer on record. Forty-one lakes in the greater Bridgton area were monitored biweekly or once seasonally for water clarity, total phosphorus, chlorophyll, and color. The impact from the excessive precipitation was visually apparent to monitoring staff (and the public) with water clarity generally lower and water color generally higher than long-term (up to 27 years) averages. Total phosphorus concentrations were also higher than average, but chlorophyll <em>a<\/em> concentrations varied little from long-term averages. These patterns were not always observed in lakes sampled one time during the summer, possibly because the visits were during a period of less rain. Despite the dramatic changes in water quality, the 2023 season caused little change to long-term trends. The observed conditions suggest that the intense precipitation caused high organic matter and total phosphorus loading, but did not lead to increased algal productivity during the season. The lack of productivity increase could be explained by lower light availability, no change in available phosphorus, increased flushing rate, or some combination of factors.<\/p>\n\n\n\n<p><strong>3:40PM-4:00PM<\/strong><\/p>\n\n\n\n<p><em>Valuing the Economic Benefits of Maine\u2019s Lakes and Great Ponds in the 21st Century<\/em><\/p>\n\n\n\n<p><strong><a href=\"mailto:jianheng.zhao@maine.edu\">Jianheng Zhao <\/a><\/strong>(1), <a href=\"mailto:adam.daigneault@maine.edu\">Adam Daigneault<\/a> (2), <a href=\"mailto:keith.evans@maine.edu\">Keith S.

This study uses a range of methodologies such as travel cost modeling, expenditure analysis, surveys, and hedonic price analysis to conduct a comprehensive assessment focused on recreation, water consumption, youth camps, and the impact of water quality on property values. We estimated that the total net economic value of Maine\u2019s Lakes is nearly $14 billion, a 15% increase over the previous study, with the largest contribution coming from lakefront properties. We also found that property owners place a premium on improved water quality: a one-meter increase in water clarity correlates with a 6.6% increase in property values, averaging $3,824 per property. Across all of Maine\u2019s lakes, a 1% improvement in water quality is estimated to add $15 million to the value for property owners. An accompanying survey on perceptions of lake water quality emphasizes the importance of water clarity in recreation choices, with the average visitor indicating lake quality at a level more than safe for swimming. Our study emphasizes the need for sustainable management of Maine\u2019s water bodies, considering ecological, social, and economic factors. The findings offer significant evidence for policymakers to include lake water quality values in environmental decision-making processes.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">About the Session Chairs<\/h4>\n\n\n\n<p><strong><a href=\"mailto:Linda.C.Bacon@maine.gov\">Linda Bacon<\/a><\/strong> fell in love with lakes at a young age and grew to appreciate the ecology of aquatic systems in college and grad school.&nbsp; After finishing her MS coursework, Linda worked on acid rain projects at the 91爆料 for five years before joining Maine DEP\u2019s Lake group in 1989, working her way up to Lake Assessment Section Leader.&nbsp; Her interests include plankton dynamics, mercury contamination, cyanotoxins, effects of climate change, as well as paddling a canoe on a quiet lake early in the morning.&nbsp; For Linda, limnology is an avocation as well as an occupation.&nbsp;<\/p>\n\n\n\n<p><strong><a href=\"mailto:rachel.hovel@maine.edu\">Rachel Hovel<\/a><\/strong> is an aquatic ecologist who studies fishes and invertebrates across a range of freshwater habitats, and Associate Professor of Biology at 91爆料-Farmington.
