This project report describes the results of an effort to gather together all the existing analytical data on mercury within various elements of the Peace, Athabasca and Slave river aquatic ecosystem. The compilation was intended to describe the temporal and spatial changes of this contaminant within the study area. While historic provincial and federal data, along with data collected by NRBS between 1992 and 1994, were the principal source of information for this report, other sources were used if available. Considerable variation was found in the data sets held by various agencies and industry. In a number of instances the variation in collection, analysis and reporting the data raised questions about reliability. Mercury is common to the sediments and biota of the study area. With few exceptions, there appears to have been a negligible increase in the occurrence of mercury within the aquatic ecosystem. This appears to contradict a general global trend which indicates an increase. Most of the exceptions within the NRBS area can be attributed to developments which promoted the release of mercury , e.g., flooding of previously exposed soils within the newly formed Williston Reservoir, run-off from site developments, and the effects appear to be localized. The compiled data illustrated the capacity for mercury to be bioaccumulated by living organisms and transferred (biomagnified) up the food chain. Consequently, fish, particularly predatory fish species like walleye, goldeye and northern pike, generally have higher levels of mercury than those species feeding on portions of the aquatic ecosystem with minimal mercury contamination. Fish, particularly walleye in the Athabasca River from the town of Athabasca to the southern boundary of Wood Buffalo National Park, were generally found to have levels that approached and / or exceeded Health Canada guidelines for human health consumption. Information from this project will be compiled with other contaminant investigations in support of two reports to be prepared by the Contaminants Component. One report will examine the distribution of contaminants , and the other will endeavor to link these analytical findings with observed effects within the aquatic ecosystem of the Peace, Athabasca and Slave rivers. REPORT SUMMARY This report summarizes and describes environmental levels of mercury in water, sediment, invertebrates, and fish from the Athabasca, Peace, and Slave river basins. Data were obtained from existing provincial and federal databases, the Northern Rivers Basins Study, and from government and private sector reports and publications. Mercury has been measured in several hundred water samples from the Basins. Mercury was detected in only a few of these samples. However, appropriate field and laboratory protocols to sample mercury in water were not used in the

    Transmission Reinforcement in the Central East (Cold Lake, Vegreville and Provost) Area For more information please contact the AESO at 1-888-866-2959, www.aeso.ca or [email protected] Who is the AESO? Alberta’s transmission system, also referred to as the Alberta Interconnected Electric System (AIES), is planned and operated by the Alberta Electric System Operator (AESO). The transmission system is comprised of the high-voltage lines, towers and equipment (generally 69 kV and above) that transmit electricity from generators to lower voltage systems that distribute it to cities, towns, rural areas and large industrial customers. Our job is to maintain safe, reliable and economic operation of the provincial transmission grid. Where is the AESO’s planning study region? The AESO’s planning study region runs from Cold Lake south through the Battle River, Wainwright and Vegreville areas, and east to the Provost area. The Central East region also covers Lloydminster, at the border with Saskatchewan. Larger communities in this region include Cold Lake, Bonnyville, Vermilion, Kitscoty, Lloydminster, St. Paul, Elk Point, Vegreville, Wainwright, Hardisty, Sedgewick, Strome, Jarrow, Edgerton, Castor, and Killarney Lake. Why is transmission development required in the Central East (Cold Lake, Vegreville and Provost) area? Transmission system reinforcement is needed in the study region to meet growing demand for electricity from oil sands development and pipelines, and to interconnect proposed gas fired electricity generation as well as wind farms in the study region. The AESO has received applications to interconnect over 500 megawatts (MW) of wind power and natural gas generation projects in Central East Alberta.

Walleye Population Status Walleye in Alberta are located near the northern edge of this species’ range, and compared to southern populations, growth rates are slower, maturity is later and consequently the fisheries are less productive. Historically, walleye were likely abundant in only about half of Alberta’s fish-bearing lakes. Many Alberta lakes are naturally limited by low oxygen, small size, or high salinity and would not have supported walleye. Collapse and Recovery Because of their popularity as a sport and commercial fish, walleye were severely overharvested in Alberta.

    Summer Lakekeepers 2019 ALBERTA LAKE MANAGEMENT SOCIETY’S OBJECTIVES

    Summer LakeKeepers 2019 ALBERTA LAKE MANAGEMENT SOCIETY’S OBJECTIVES The Alberta Lake Management Society (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 from Graham Lake, Haig Lake, Snipe Lake, Swan Lake, Lac La Nonne, Tait Lake, Westover Lake, and Beauvais Lake. We would also like to thank the Mighty Peace Watershed Alliance 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 Bradley Peter and Caleb Sinn. EXECUTIVE SUMMARY In 2018, the Alberta Lake Management Society (ALMS), 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 the first Summer LakeKeepers season in 2018, five lakes were sampled for a total of 14 monitoring trips. To see the results of the Summer LakeKeepers 2018 sampling program, find the report on our website (https://alms.ca/reports/).
  • Lac La Nonne Fisheries Management Objectives

    Lac La Nonne Fisheries Management Objectives

    Lac La Nonne Fisheries Management Objectives Summary Information Version Date: Prepared by: Reviewed by: Approved by: October 2018 Nate Medinski Marcel Macullo Curtis Brock Waterbody ID: Surface Area: Hydrologic Unit Code Hydrologic Unit Code (HUC_8): 5448 1293 Ha Name (HUC_8): Lower 17030201 Pembina River Sport Fish Species: Walleye, Northern Pike, Yellow Perch, Lake Whitefish, Burbot Indigenous Fishery: Yes Environment and Parks Region: Fisheries Management Fisheries Management Office: Upper Athabasca Region (UAR) Zone: Northern Boreal Athabasca 2 (NB2) Background Lac La Nonne is located approximately 90 km northwest of Edmonton. It supports a sport fishery for walleye, northern pike, yellow perch, lake whitefish and burbot that receives very high angling pressure due to the local communities and villages, campground facilities and short travelling distance from the Greater Edmonton Area. A commercial fishery previously existed on Lac La Nonne, with detailed records dating back to the 1940’s. Commercial fishing no longer occurs anywhere in Alberta, including at Lac La Nonne. Prior to 1998, regulations which permitted the overharvest of walleye stocks resulted in a decline in population abundance, ultimately resulting in a collapsed recreational fishery. In response to the observed declines, catch and release regulations were implemented from 1998 through 2009, allowing the walleye fishery to recover. In order to create a sustainable harvest walleye fishery, a Special Harvest License (SHL) system was implemented in 2010. The SHL was implemented successfully until 2015, when a severe winterkill occurred. Since the winterkill event, SHL tags have not been allocated to expedite the recovery of the walleye population. Fall Index Netting (FIN) following the winterkill revealed that walleye and lake whitefish suffered substantial population declines, whereas other fish species decreased in abundance but to a lesser degree.
