Partners Sponsors Media Partner 22nd Annual River Symposium 2 BIOGRAPHY 2015 River Symposium—St. Lawrence Power Development Visitor Centre Special Guest Chair and Guest Speaker Dr. Anthony Ricciardi is a professor in the Faculty of Science at McGill University, where he teaches courses on freshwater biology, animal diversity and environmental science. He serves on the scientific committee of the Canadian Aquatic Invasive Species Network – a national research group that assesses the risks of invasion in Canada’s lakes, rivers and coastal waters. For over 20 years, his research has examined the ecology of the St. Lawrence River and the Great Lakes, with a strong focus on the effects of invasive species. May 5, 2015 7:00 pm Schnitzels Restaurant Pandora’s Ballast Tank: How Invasive Species are Changing the St. Lawrence River Biological invasion – the spread of non-native species – is transforming ecosystems worldwide. No other freshwater system contains as many non-native species, or has been invaded as frequently, as the Great Lakes-St. Lawrence River basin. Over 180 non-native species have become established in the basin within the past two centuries. Collectively, these invasions have altered biodiversity, water quality, fish habitat, productivity, and contaminant cycling, in the lakes and in the river. Most invasions have occurred since the opening of the St. Lawrence Seaway and are attributable to ballast water release from overseas shipping. Recent regulations seem to have reduced the threat of foreign ballast water, but non-native species may continue to be introduced through poorly-regulated vectors, such as those associated with ‘live trade’ (species imported as baitfish, ornamental garden species, aquarium pets, and food for human consumption). The spread and impact of current and future invaders are expected to be altered by climate change. For these reasons, the Great Lakes-St. Lawrence River system may experience further ecological disruptions from invaders in the coming decades. May 6, 2015 10:30 am Ontario Power Visitor’s Centre Microplastics in the St. Lawrence River: What are they, Where do they come from, and What is their significance? Microplastics – polymer particles originating from the use and manufacture of household or industrial products – have long been recognized as a global contaminant in the world’s oceans. In recent years, they have also been detected in the surface waters of the Great Lakes and other freshwater lakes and rivers worldwide. In 2013, students from my lab at McGill University discovered microplastics in the form of polyethylene ‘microbeads’ (less than 2 mm in diameter) widely distributed across the bottom of the St. Lawrence River, the first time such pollutants have been found in freshwater sediments. The microbeads likely originate from a combination of household and industrial sources. At some locations, we measured over a thousand microbeads per liter of sediment, a concentration that rivals the world’s most contaminated ocean sediments. Contrary to the assumption that floating microplastics are flushed through rivers to the sea, our study shows that rivers can act as a sink for this pollution. I will discuss the potential for microplastics to be consumed by fish and other animals, and the ecological significance of this novel contaminant in the St. Lawrence River. 3 TUESDAY, M AY 5, 2015 2015 River Symposium—St. Lawrence Power Development Visitor Centre Main Hall Welcome—Traditional Native Opening Jeff Ridal, Executive Director, River Institute 9:00 New Sources Of Contamination In The Great Lakes/St. Lawrence River Session Chair: Roxanne Razavi, St. Lawrence River Institute of Environmental Sciences 9:15 Overview of the State of the St. Lawrence River 2014 Caroline Savage, Environment Canada 9:35 Endocrine-related Health Effects and Elevated Concentrations of PCBs and Mercury in Wild Fish at the St. Lawrence River (Cornwall) Area of Concern Marcel Pinheiro, University of Waterloo 9:55 The Effects of Diluted Bitumen (dilbit) from Canada's Oil Sands Region on Embryotoxicity in Fish - Implications for its Transport in Vital Watersheds Barry N.

In 2010, algal blooms were sampled to determine the species of algae that were blooming and why this was occurring. This research indicated that primarily green algae was found but that future research was needed in order to determine causes of their increased growth. In order to gage a good understanding of the public's concern regarding algae and aquatic plant growth a survey was conducted. These survey results indicated that lake and river users were noticing increased growth and would like research to be completed to understand why it is occurring. From this information the collaborative group was formed, and applied to the Ontario Trillium Foundation to conduct research and education on algae and aquatic plants in Eastern Ontario. This initiative was successful and the project is starting its second and final year. Through this project 20 sediment cores were sampled and macrophyte mapping was conducted to gain an understanding of the influence that total phosphorus, invasive species and climate change have had on these lake ecosystems. Knowledge from this research will help guide stewardship actions that can be taken on our local lakes and rivers. After the completion of this project, the collaborative group will continue to find additional funding and resources to put towards important research on lakes and rivers and to apply this knowledge to maintain watershed health. Kaitlin Brady Rideau Valley Conservation Authority EVALUATING WETLAND RESTORATION SUCCESS IN THE ST. LAWRENCE RIVER VALLEY: BIOINDICATORS AND WATER QUALITY Carberry, Brendan, Dr. Tom A. Langen, and Dr. Michael R. Twiss The St. Lawrence River valley contains widespread potential for wetland restoration and preservation, especially through the creation of public-private partnership wetland easements. Although hundreds of easements exist in the region, variations in construction, hydrology, and connectivity, as well as logistical challenges in long term monitoring make it difficult to define and measure restoration success. This study focuses on 50 wetland restoration projects constructed through public-private partnerships with the National Resources Conservation Service, U.S. Fish and Wildlife Service, and Ducks Unlimited, along with 18 natural reference wetlands. At each site we conducted biodiversity surveys using biotic indicators including turtles, frogs, fish, birds, and plants. Each site was then sampled for water quality analysis including algal and bacterial community composition, pH and alkalinity, and nutrient analysis. The results of these surveys are being used as ranking criteria to evaluate wetland restoration success and quantify environmental benefits of wetlands. The outputs of this study will be used to provide recommended practices to guide agencies in wetland restoration sites and partners and in project monitoring.

LAWRENCE RIVER Brown, Brandy L., Jacob Runner, and John M. Farrell Restoration efforts of Northern Pike habitat in the Thousand Islands has focused on re-establishing connectivity to remaining coastal wetland spawning habitat that has been negatively impacted by the invasive cattail, Typha x. glauca and the suppression of water level fluctuations. Spawning marshes, excavated channels, and spawning pools are three techniques that were used and evaluated since 2002. Fish usage and density of emigrating age-0 Northern Pike was compared among the three restoration techniques. Restored channels and pools attracted both spawning and resident fishes and captured numerous age-0 Northern Pike, indicating successful reproductive function. Surveys indicate spawning marshes have not reached expected juvenile production despite a positive habitat response, likely due in part to changes in adult spring migrations. Recent habitat improvement however, continues, and it is anticipated that Northern Pike populations will benefit from these projects at the local level. System-wide population responses may require a larger scale intervention, such as changes to water levels management policy. Specific project successes, challenges, and lessons learned from a restoration and management perspective will be highlighted and discussed. John M.

Gibbs, and Sarah Fleming* State University of New York College of Environmental Science and Forestry, 1 Forestry Dr. Syracuse, NY 13210, (315 4706990), [email protected]; *Ducks Unlimited Inc. An intensive and holistic monitoring study was completed to evaluate outcomes and provide baseline data for coastal wetlands habitat restoration in the upper St. Lawrence River. The project included water-control structures designed to expand the hydropattern and excavated spawning pools to enhance connectivity in invasive cattail dominated wetlands. This evaluation was holistic as it considered seasonal biogeochemical processes and nutrient dynamics and included experiments and field data linkages to lower trophic levels including algae and zooplankton. In addition, more traditional plant community responses were evaluated using analyses of plant community structure along wetland elevation gradients and on post-restoration habitat mounds. Faunal responses to the projects were examined including herpetofauna, avifauna, muskrat (Ondatra zibethicus), and fish, including reproduction of the restoration target species, Northern Pike (Esox lucius). We present an overview of the range of studies completed for this wetland habitat, its modification, and early indications of the efficacy of the restoration performance. Because of the wetland sensitivity to hydrology, the approach will also help guide 9 understanding of International Joint Commission (IJC) water-level regulation policy effects on coastal marsh ecology. COASTAL WETLAND HABITAT RESTORATION IN THE ST. LAWRENCE RIVER AND LAKE ONTARIO BASIN: DELIVERY METHODS, PARTNERSHIPS, AND LESSONS LEARNED Fleming, K. Sarah, and J. M. Farrell Research has demonstrated that the natural processes of the coastal freshwater marshes and nearby tributaries of Lake Ontario have been altered by water level stabilization and changes in land use and climate. These changes and lack of water level fluctuation have caused environmental damage to critical spawning habitat for the region’s fishery resources and reduced the diversity of wetland-dependent wildlife. Following St. Lawrence and Lake Ontario water level regulation in 1960, coastal marshes have increasingly been dominated by invasive dense cattail mats that have limited value for spawning fish and wetland-dependent wildlife, including northern pike and marsh birds, respectively. Ducks Unlimited, Inc. (DU) and a diversity of conservation partners, funded through the Great Lakes Restoration Initiative (GLRI), are advancing coastal wetland restoration projects in the St. Lawrence River and Lake Ontario watershed. Projects include restoration of potholes and channels in dense cattail to connect to marsh and lake habitats, habitat mounds to increase plant diversity, and installation of fish ladders. Pre- and postmonitoring suggests improved fish and wildlife habitats in coastal wetlands and their tributaries with the increased connectivity to open lake and riverine habitats. Through strong conservation partnerships, DU helps deliver science-based, solution-oriented conservation for waterfowl, wildlife, and people. Since 2010, DU has networked with a diversity of stakeholders with similar holistic approaches to conserving Great Lakes coastal marshes and we will discuss how our partnerships ensured successful project delivery, as well as what lessons were learned through our delivery methodology K.

Hydro generation at Espanola Falls, and additional upstream power stations have been thought to pose significant risks to Lake Sturgeon. A TELEMAC hydrodynamic model was calibrated for the river system under two flow regimes, then used to estimate water depth and flow velocities for the receiving environment downstream of Espanola Falls for the sturgeon spawning periods in each year from 2001 to 2011. Hydrodynamics were modeled for four operational scenarios (flow regimes) that included: (1) existing conditions (i.e., modest peaking); (2) smoothed peaking; (3) run-of-river; and (4) naturalized flow regime. The hydrodynamic model results were then used as input to a spawning habitat suitability model that considered flow velocities, water depth and substrate texture, and predicted conditions for pixels of ~6 m2 in size. The model also considers water temperature, the timing of spawning, and the likelihood that eggs will go dry because of variations in water elevations. A combination of egg mats and radio 10 telemetry confirmed that the plunge pool beneath Espanola Falls is used by Lake Sturgeon as a spawning ground validating the hydrodynamic modelling results. C. Hatry Kilgour & Associates Ltd. Ottawa, Ontario ONTARIO EAST ALTERNATIVE LAND USE SERVICES - WORKING WITH FARMERS AND RANCHERS TO INCREASE NATURES BENEFITS ON THEIR LAND Jacobs, Brendan Ontario East Alternative Land Use Services (ALUS) Inc. is a community based, farmer led and delivered program with the simple goal of creating a healthy environment that sustains agriculture, wildlife, and natural spaces for all Canadians. ALUS recognizes and endeavors to augment the key role farmers and ranchers play as land stewards by increasing nature’s benefits through the naturalization of marginal and fragile areas, currently under production. In exchange for these benefits the farmer receives an annual payment per acre enrolled in the ALUS program. The ALUS process is not prescriptive, which allows for greater flexibility when it comes to project design and the establishment of wetlands, buffers, pollinator habitat, wildlife structures, and tree planting. A number of these projects types are geared to improving water quality at a local and watershed level through the reduction of nutrient inputs and sedimentation. Brendan Jacobs Program Coordinator Ontario East Alternative Land Use Services (ALUS) Inc. UPDATE ON THE FISHERIES IN THE ONTARIO WATERS OF LAKE ST. FRANCIS Colin Lake, Jim Hoyle, Alastair Mathers Abstract: An update on the fish community of Lake St. Francis, using information from various assessment programs, including gill netting and angler surveys. Fish community assessment netting provides a measure of health for several species. The 2014 survey suggests the yellow perch are relatively abundant overall, however the large fish preferred by anglers have declined. Populations of walleye and smallmouth bass appear to be thriving, while northern pike are declining. Data from both the recreational and commercial fisheries will be presented as well, focusing particularly on Yellow Perch – a species that supports a regionally-important fishery. Updates on management activities in Lake St. Francis and the St. Lawrence River will be given, including the Lake St. Francis Fisheries Management Plan (FMP) and the St. Lawrence River Fish Community Objectives (FCOs).

Benson, More than 200 wetland restoration projects have been completed in the St. Lawrence River Valley, restored with a goal of returning to the landscape wetlands that were lost due to past land-use practices, mainly drainage for agriculture. Wetland restorations are intended to provide the same ecosystem services as natural wetlands, and habitat for the same community of wetland-associated plants and animals. As a complement to our study comparing wetland associated-biodiversity between natural and restored wetlands within the St. Lawrence Valley of New York State, we conducted a formal metaanalysis of all accessible research that compared biodiversity indicators of wetland quality between restored and reference natural wetlands. We found that, in aggregate, most studies have results similar to ours in the St. Lawrence Valley: there is no difference between wetland restorations and matched natural wetlands in terms of the species richness, abundance, and composition of wetland-associated biodiversity. We conclude that restoration programs are generally worthwhile for restoring to landscapes wetlands lost to agriculture or other land-uses. Tom A. Langen Clarkson University E-mail: [email protected] LINKING THE MOSES SAUNDERS DAM TO WETLAND TRIBUTARIES IN THE ST. LAWRENCE RIVER Looi , Alexander, Kimberly L. Schulz, John M. Farrell, Charles Kroll, and Ceili Bachman. The Moses Saunders Dam (MSD) strongly influences the water levels and volume of the St. Lawrence River and Lake Ontario. The MSD also impacts water levels in connected drowned river mouth wetland ecosystems that reside in tributaries of the St. Lawrence River. Consequently, ecosystem processes in these wetlands such as nutrient concentration, productivity, and composition of the biota are influenced by the MSD. Three pairs of wetland sites had hourly water levels measured between 2012 and 2013. Each pair had one unregulated and one regulated tributary. Regulated tributaries contained a flow control structure that removed influence of the MSD. These data were compared with water level data taken from the Alexandria Bay NOAA water level gauging station (ABAN 6) in the St. Lawrence River closest to our study sites. Linear regression was used to describe the relationship between St. Lawrence River level and our wetland sites. A watershed model (GWLF) was used to simulate water flow into the wetlands. Finally, historic water levels of the wetland sites were simulated to hindcast past conditions and prior to the MSD, water levels on the St. Lawrence experienced greater fluctuations. We examine the hydrodynamic linkages between Alexandria Bay and those of tributary wetlands to examine potential impacts of water levels regulation.

Madison, Barry N., Peter V. Hodson, and Valerie S. Langlois Water is our most precious biological resource at a time when oil is Canada's most valued economic resource. This dichotomy is central to current and future political debate, on a local and global scale. One central question to this discussion is what are the long-term implications of oil sands products on our freshwater supply? Examination of the biological cost of these products must be performed in order to make appropriate decisions that affect both long-term environmental and fiscal policies. Though work has assessed the toxic effects of oil sands products on fish and aquatic life in general, little has been done to characterize the sensitivity to earlier sedentary life stages of fish species, e.g., embryos, to the impacts of potential oil spills near major watersheds where dilbit is nationally transported, including those along future routes (e.g., Northern Gateway). Our work on the impact of dilbit exposure on developing fish has revealed novel physicochemical and toxicological attributes of this product as it sits poised for export to international markets via major shipping routes. Initial efforts with model fish species are identifying relevant biomarkers of dilbit exposure to allow the future assessment of which Canadian species will most likely be affected by potential spills Barry N.

Field sites on operating commercial farms within the Great Lakes/St. Lawrence River basin have been instrumented and monitored year-around to gain an improved understanding of how and when water and phosphorus leave a farm field. Both tile drainage flows and overland runoff flows are being monitored for water quantity and quality. Field management activities are also being recorded. Seasonal and annual loadings of phosphorus in drainage waters can be calculated and compared against phosphorus inputs, phosphorus losses attributed to crop removal, and the soil’s inherent phosphorus supply. With instrumented sites in place, the ability to evaluate the impact of phosphorus recycling strategies such as manure application to cropland can be assessed. Best practices promoted to minimize sediment and phosphorus loss can also be evaluated as they are implemented in the course of producing crops on the monitored fields. Key observations to-date are summarized. Results from a separate study which used a modelling approach to assess the impact of individual field practices at a rural watershed outlet are also presented. Shortcomings in existing rural water quality modelling tools are discussed as are the challenges in formulating policy to address phosphorus losses in agricultural drainage waters. Kevin McKague P Eng., CPESC 13 Ontario Ministry of Agriculture, Food and Rural Affairs Woodstock, ON N4T 1W2 DEVELOPING A BAY OF QUINTE PHOSPHORUS REDUCTION STRATEGY Mugalingam, Shan One of the main environmental issues with the Bay of Quinte has been the impacts associated with excess nutrient loadings, particularly phosphorus. In aquatic ecosystems like the Bay of Quinte, the ability of phosphorus to promote rapid primary production causes a variety of eutrophication related problems. Since the 1970s, there have been significant reductions in the amount of phosphorus entering the Bay from both point sources, such as sewage treatment plants, and non-point sources, such as urban and rural run-off. Despite the gains, the Bay continues to experience the effects of eutrophication and recent assessments suggest that sediment phosphorus re-flux mediated through zebra mussels and macrophyte beds is maintaining the phosphorus levels in the Bay at a relatively steady level. The development of a long-term Phosphorous Reduction Strategy for the Bay of Quinte is one of the remaining key activities to be undertaken in order to delist this Great Lakes Area of Concern. The goal of the Strategy is to restore and maintain the Bay to a healthy and sustainable condition for the long term by reducing the risk of harmful algae blooms, while maintaining the sustainable fisheries in the bay. The Strategy will also need to off-set the effect of the sediment phosphorus re-flux on the phosphorus levels of the Bay. This talk will explore the steps taken to establish phosphorus loading targets for the Bay and the issues that will need to be considered in the development of a Phosphorous Reduction Strategy. Mugalingam, Shan Lower Trent Conservation ENDOCRINE-RELATED HEALTH EFFECTS AND ELEVATED CONCENTRATIONS OF PCBS AND MERCURY IN WILD FISH AT THE ST. LAWRENCE RIVER (CORNWALL) AREA OF CONCERN Pinheiro, M.D.O., Simmons, D.B.D., Villella, M. 2, Park, B.J., Tetreau lt, G. R., Muir, D.C.G., McMaster, M.E., Hewitt, L.M., Parrott, J.L., Brown, S.B., Sherry, J.P. The extent that historical sources of mercury and PCBs continue to influence wild fish health in the Area of Concern (AOC) was assessed by means of various endocrine and reproductive endpoints. Yellow Perch (Perca flavescens) and Brown Bullhead (Ameiurus nebulosus) were sampled in 2004-5 within the AOC, at Cornwall and downstream at Gray’s Creek, and compared to fish sampled upstream at Morrisburg, ON. Body burden analysis combined with biomarkers of exposure indicated that fish contained low but significant levels of mercury and PCBs, resulting in subtle effects on health. Particularly, female Brown Bullhead showed signs of reproductive impacts, with reduced levels of plasma sex steroid and vitellogenin protein. Metabolic health was also affected in these fish, as determined by biometric measurements, biomarkers, and histological measurements indicative of thyroid function. Although the original industrial sources of mercury and PCBs no longer operate within the AOC, the continued impacts of historical contaminants such as PCBs and mercury points to the need for continuing, long-term assessments of fish health in the Cornwall AOC.

LAWRENCE RIVER 2014 Savage, Caroline For the third time (2003, 2008, 2014) the Working Group on the State of the St. Lawrence has met the challenge of establishing an overview of the state of the St. Lawrence as part of the Canada–Québec Agreement under the St. Lawrence Plan, also known as the St. Lawrence Action Plan 2011–2026. To accomplish this task, the group used the findings of many scientists (19 indicators on water, biological resources and sediments) from the organizations involved in implementing the State of the St. Lawrence Monitoring Program. In 2014, the river’s bill of health presents a fragile balance. Most indicators remain moderate. Following the reintroduction of the Striped Bass, we are seeing significant progress in the natural reproduction, growth, and distribution of this species in the river. Overall, however, the St. Lawrence remains relatively vulnerable. The Beluga Whale and Northern Gannet populations have experienced significant degradation. Several changes have been observed in the ecosystem of the upper estuary, the lower estuary and the Gulf. Caroline Savage M.sc.

Langen The natural wetlands along the St. Lawrence River in New York have been impacted by major habitat alteration and contamination that occurred as a consequence of the St. Lawrence Seaway Project and historical industrial development. For this reason, the sector of the St. Lawrence River near Massena New York and Cornwall, Ontario has been designated as a bi-national, environmental Area of Concern (AOC). In recent years, various environmental restoration and remediation projects have been implemented in the area; however, there is a recognized information gap as to whether these environmental mitigation projects have been successful in restoring the beneficial use impairments (BUIs) identified for the AOC. We have been funded by the St. Lawrence River Research and Education Fund (SLRREF) to evaluate wetland habitat quality by surveying five biological indicators (birds, reptiles, amphibians, fish, plants) and fourteen indicators of water quality (e.g. oxygen, nutrients, turbidity, phytoplankton) within a representative sample of wetlands in the Massena AOC and a comparable set of reference wetlands form outside the AOC. Results indicate that overall wetland habitat quality in the Massena AOC does not differ from that of reference wetlands with respect to water quality and diversity of wildlife. However, we found that reference wetlands outside the AOC are larger while wetlands in the Massena AOC are covered by a higher percentage of invasive plant species. We concluded that the Remedial Action Plan implemented in Massena has been successful at reducing the extent of wetland impairment and restoring wetland habitat.

B.J. Carberry T.A. Langen The ecological functioning of a wetland can be influenced by inherent water quality. We sampled 46 restored and 17 natural wetlands over a 33 day period (DOY 204-237, 2014) to determine if there is a difference in water quality between these two sets of wetlands that were also assessed for ecological function. Grab surface water samples were collected with a pole from each wetland, and processed that day. All statistical analyses were conducted using a t-test on untransformed data, with two-tailed distributions and assuming normal variance. No significant difference between Natural and Restored wetlands were detected for CDOM, turbidity, phytoplankton community composition, nitrate, total chlorophyll-a*, chloride*, or sulfate*, although the last three variables (*) show a trend of greater concentrations in restored wetlands. Natural wetlands had 30% greater FC concentrations. Natural wetlands (pH 6.70) were 3.3 times more acidic than restored wetlands (pH 7.22), calculated by comparing {H+} of lab pH. Accordingly, natural wetlands had 1.5-times lower alkalinity and specific conductivity. Thus, it appears that restored wetlands have greater concentrations of solutes in them, which might reflect a closer connection to terrestrial habitats, in particular marine clays. With respect to the more acidic natural wetlands, perhaps wetlands that were in naturally acidic areas had acidic low quality soils and were thus avoided by farmers due to poor soil condition. Hence, these are the wetlands that remain in a natural state. Therefore, a different water quality should be expected between a restored wetland and natural wetlands in this region.

FRANCIS THROUH INTENSIVE SAMPLING AND THE HELP OF CITIZEN SCIENTISTS Waller, M. E. Cumming, B. F. and Bramburger, A. J. In recent years, occurrences of nuisance algae have been reported in the watershed and nearshore area of Lake St. Francis, a fluvial portion of the St. Lawrence River near Cornwall, Ontario. These nuisance algae blooms have been known to include potentially hazardous cyanobacteria (blue-green algae) species. There is a concern that algal blooms are occurring more frequently and that adverse impacts to wildlife, human activities and public health could occur. However, there is a general lack of information on the location, frequency and types of algal occurrences in this part of Eastern Ontario. My research seeks to address this lack of information through intensive sampling in order to create the information that is necessary to document the occurrence of nuisance/harmful algal blooms and their associated environmental conditions. Analysis of this data will allow possible causative factors (e.g. land use, weather and water quality) to be identified. The sampling network was also expanded and sampling frequency increased through the help of citizen scientists, their input into the detection of bloom events will be assessed.

There are a number of federal programs which fund wetland improvements in return for participation in such programs by private landowners and establishment of conservation easements. There is a dearth of information on the effectiveness of such programs in a number of important areas. In addition, there is little research on whether participation in the programs, net of other variables, influences participants’ attitudes about the importance of wetlands. Using a survey of 35 landowner participants and 24 neighbors of preserved and improved wetlands we find that participation in the program is not a significant predictor of valuing wetlands. Important predictors were membership in an environmental or conservation group and how neighbors and participants utilized wetlands. Rick Welsh Syracuse University 17
