  • Wabamun Lake Water Quality 1982 to 2001
    WABAMUN LAKE WATER QUALITY 1982 TO 2001 WABAMUN LAKE WATER QUALITY 1982 TO 2001 Prepared by: Richard Casey, M.Sc. Limnologist Science and Standards Alberta Environment September 2003 W0309 Pub. No: T/695 ISBN: 0-7785-2503-1 (Printed Edition) ISBN: 0-7785-2504-X (On-Line Edition) Web Site: http://www3.gov.ab.ca/env/info/infocentre/publist.cfm Any comments, questions, or suggestions regarding the content of this document may be directed to: Environmental Monitoring and Evaluation Branch Alberta Environment 10th Floor, Oxbridge Place 9820 – 106th Street Edmonton, Alberta T5K 2J6 Phone: (780) 427-6278 Fax: (780) 422-6712 Additional copies of this document may be obtained by contacting: Information Centre Alberta Environment Main Floor, Great West Life Building 9920 – 108th Street Edmonton, Alberta T5K 2M4 Phone: (780) 944-0313 Fax: (780) 427-4407 Email: [email protected] SUMMARY Wabamun Lake, approximately 60 km west of Edmonton, is large, shallow, and generally well mixed. Sport fish in the lake include northern pike, yellow perch, and lake whitefish. There are a unique mix of land uses in the lake watershed, which include undisturbed bush and forest, agriculture, two coal mines with active and reclaimed areas, three coal-fired power plants, major transportation (road and rail) corridors, residences, and recreation. The mines supply fuel for the power plants, operated by the TransAlta Utilities Corporation (TAU). Industrial wastewaters, runoff and cooling water from the Whitewood mine and Wabamun power plant are discharged to the lake. Over time, TAU operations associated with the mines and power plants in the watershed have caused cumulative and ongoing impacts on the lake level.

  • Moose Lake Handbook
    Moose Lake Our Past - Our Home - Our Future Moose Lake has a rich history starting with the fur trade and continually evolving to today with over 10,000 visitors annually. The area is under pressure from development such as subdivisions, lakelots, campgrounds, industry, agriculture and recreation; as well as the wildlife that make the lake their home. The Moose Lake Watershed Society (MLWS) recognizes that watershed management is vital to conserving the lake and maintaining its ecological value that we all can enjoy. The Moose Lake Water- shed Society is pleased to provide this handbook, which helps us achieve our vision as well as work to complete our Moose Lake Watershed Management Plan goals. Vision To maintain a healthy and func- tioning Moose Lake Watershed and recognize the importance of living within the capacity of the natural environment as a means of ensuring sustainable environ- mental, economic and social values. Acknowledgments This handbook was created for the Moose Lake Watershed Society by Kellie Nichiporik, with the assis- tance of the staff of the Beaver River Watershed Alliance and reviewed by members of the Moose Lake Watershed Society. Photos by Kellie Nichiporik. Thank you to the Lac La Nonne Enhancement and Protection Association, Waters Edge Resource Group and Lac La Nonne Watershed Stewardship Society for their pioneering accomplishments of the Lac La Nonne and Nakamun Lake Handbooks, upon which this project is based. Thank you to Bill Fox for providing the history of Moose Lake. Thank you to Lakeland Agricultural Research Association and Cows and Fish for providing resources and assistance.

  • Cyanobacteria Commonly Form Blooms on the Surface of Productive, Warm, Stable Lakes and Reservoirs

Common species of cyanobacteria can produce potent liver and/or nerve toxins. Microcystins (MCYSTs) are thought to be the most common toxins produced by cyanobacteria and exert toxicity by severely damaging liver structure and function. They have been linked to high incidence of primary liver (hepatocellular carcinoma) and colorectal cancers in some countries. Cyanotoxin monitoring was incorporated into Alberta’s Integrated Lake and Reservoir Monitoring Program in 2005 with the goal of determining the prevalence of MCYST in Alberta. In addition, we investigate the occurrence of multiple MCYST analogues, a potent neurotoxin anatoxin-a (ATX-a), and a potentially toxic amino acid, β-N-methylamino-L-alanine (BMAA) recently reported to be produced by cyanobacteria.

  • Winter Lakekeepers 2019
    Winter LakeKeepers 2019 ALBERTA LAKE MANAGEMENT SOCIETY’S OBJECTIVES ALMS has several objectives, one of which is to collect and interpret water quality data on Alberta Lakes. Equally important is educating lake users about their aquatic environment, encouraging public involvement in lake management, and facilitating cooperation and partnerships between government, industry, the scientific community and lake users. ALMS would like to thank all who express interest in Alberta’s aquatic environments and particularly those who have participated in the LakeKeepers program. These leaders in stewardship give us hope that our water resources will not be the limiting factor in the health of our environment. ACKNOWLEDGEMENTS The LakeKeepers project was made possible with support from Alberta Ecotrust. We would like to thank the volunteers who made this program happen: Jon Pedlan, Ray Walker, Vien and Marielle Lam, Cam and Brittany Kereliuk, Kellie Nichiporik, Steve Hawryliw, and Blake Mills. We would also like to thank the Mighty Peace Watershed Alliance, the Alberta Conservation Association, and the Calling Lake Cottage Association for their assistance with coordinating volunteers and sample shipment. A special thanks to Cerina Lee for developing the LakeKeeper training videos. This report has been prepared by Caitlin Mader, Bradley Peter, Patrick Heney, and Caleb Sinn. EXECUTIVE SUMMARY In 2018, the Alberta Lake Management Society, with financial support from Alberta Ecotrust, piloted the LakeKeepers project. This project was designed to enable stewards to conduct lake monitoring by providing them with training and sampling equipment. In early 2019, this project was expanded to include winter under-ice sampling, with the cooperation of ice anglers.

  • The Fish and Fisheries of the Athabasca River Basin
    THE FISH AND FISHERIES OF THE ATHABASCA RIVER BASIN Their Status and Environmental Requirements Ron R. Wallace, Ph.D. Dominion Ecological Consulting, Ltd. and Peter J. McCart, Ph.D. Aquatic Environments Ltd. for Planning Division Alberta Environment March 31, 1984 PREFACE Thi s report was prepared by consul tants supervi sed by Bryan Kemper for Planning Division of Alberta Environment, and Dave Rimmer for Fish and Wildlife Division of Alberta Energy and Natural Resources. The Fisheries Overview series of reports have been commissioned to summarize known data to assist river basin planning studies and assist in the planning of new studies with the appropriate management agencies. The opinions expressed in this report are based upon written and verbal i nformati on provi ded to the consultant and therefore do not necessarily represent those of Alberta Environment. EXECUTIVE SUMMARY The information presented here reviews what is currently known of fish ecology and production of the Athabasca Basin, and includes discussions of fish production, sport and commercial use of fish popul ati ons, and alternative opportuniti es for recreational fi shi ng in the rivers of the Athabasca Basin. Fisheries management objectives for the basin rivers and data gaps in existing knowledge of fish and fisheries are also discussed. In addition, water quality criteria for the protection of fish and aquatic life have been referenced, and, where possible, stream flows which affect fish populations have been included. The Athabasca Basin accounts for 23% of the land area of Alberta. For the purposes of this report, the basin has been divided into 10 sub-basins: four mainstem sub-basins, and six tributary sub-basins.
