Fisheries Research Board of Canada Annual Report to the Great Lakes Fishery Commission Fisheries Research Board of Canada ANNUAL REPORT to the GREAT LAKES FISHERY COMMISSION of activities carried out under a Memorandum of Agreement during the period APRIL 1, 1964 to MARCH 31, 1965 With Investigators' Summaries as Appendices Fisheries Research Board of Canada ANNUAL REPORT to the GREAT LAKES FISHERY COMMISSION of activities carried out under a Memorandum of Agreement during the period April 1, 1964 to March 31, 1965 With Investigators Summaries as Appendices 1 Annual Report to the Great Lakes Fishery Commission for 1964-65 This report is submitted in - compliance with terms of a Meinorandum of Agreement between the Fisheries Research Board of Canada and the Great Lakes Fishery Commission. Appended are detailed accounts by those responsible for specific aspects of the program. MAINTENANCE OF ELECTRICAL BARRIERS Barriers were maintained and operated on the eight Lake Superior streams specified in the Memorandum of Agreement, namely: Big Carp, Harmony, Chippewa, Batchawana, Sable, Pancake, Pays Plat, and Big Gravel. Except for a few insignificant interruptions, all eight barriers were operated con- tinuously from May 15 to July 31 inclusive. Details on lampreys counted at the barriers are given in Appendix 1, and information on sex and size is given in Appendix 4. As Appendix 2 indicates, an unusual amount of barrier main- tenance was required in 1964. Although not specified in the Memorandum of Agreement, but as pro- vided for in paragraph 5 of same, electrical barriers were constructed on three Lake Huron streams: Root River, Garden River, and at the junction of the Naiscoot and Harris Rivers. Preliminary arrangements were also made for the acquisition of sites for eight other barriers on Lake Huron streams. Almost all of the material used in the new barriers- had been salvaged from Lake Superior barriers that had been dismantled several years ago. Details are given in Appendix 3. CHEMICAL TREATMENT OPERATIONS Surveys: Routine re-surveys were carried out on 49 Lake Superior streams. As a result one stream, Blende Creek, was added to the list of streams known to harbor sea lampreys. Post-treatment surveys were carried out on 14 Lake Superior streams; they indicated that sonie sea lamprey ammocoetes had survived treatment in Stillwater Creek and in West Davignon Creek. Surveys designed to determine which streams harbor sea lamprey ammo- coetes were carried out on 136 streams tributary to Lake Huron, on 23 streams tributary to the connecting waters between Lakes Huron and Erie, on 174 Lake Erie streams, and on 293 Lake Ontario streams. As a result, the list of streams known to harbor sea lamprey ammocoetes was increased as follows; 4 2 Lake Huron by 0; connecting waters by 1; Lake Erie by 4; Lake Ontario by 5. nn. Canadian tributaries of the Great Lakes have now been surveyed at least ,Ance. The number of tributaries of each known to harbor sea lamprey am- *mocoetes is as follows: Lake Superior, 38; Lake Huron, 38; Lake St. Clair, 1; Lake Erie, 6; Lake Ontario, 21. An electrified beam trawl was again used to assess the prevalence of lake-dwelling sea lamprey ammocoetes. The already known lacustrine population in Batchawana Bay seemed relatively unchanged from 1963. None were found in hauls that covered an estimated total of 11,000 square yards in Michipicoten Bay. Lacustrine sea lamprey ammocoetes were found in Nipigon Bay off the Jackfish River, also in Helen Lake, an expansion of the Nipigon River. Detail on the above surveys are given in Appendices 5, 6, 7, 18 and 19. Treatment: - Of 15 streams specified in the Memorandum of Agreement, 14 were treated. Exceptionally heavy rains made treatment of the Black Sturgeon River impractical. Blende Creek, where sea lampreys were undiscovered un- til 1964, was treated after consultation with the Commission's Secretariat. The synergist, Bayer 73, was used in conjunction with the usual lam- pricide, TFM, in all the larger streams that were treated in 1964. The amount of TFM needed when Bayer 73 was added was notably less than with TFM alone. Treatment costs were materially reduced by adding the synergist. It soon be- came apparent, however, that in small streams the amount saved on chemical costs by using Bayer 73 is not worth the difficulties that result from a tendency for the synergist to clog the app'aratus used to introduce lampricides into the stream' s, thereby damaging equipment, slowing the work, and ,increasing the chances of failure of the treatment. The synergist was therefore not used on small streams. A number of minor studies associated with lamprey bi ol ogy have been car ried out. They were des igned to yi el d i nf or mat ion 1 ikel y to i ncr eas e the ef fect ivenes s of the treatment pr ogr am and/or per t inent t o s upplying information on the ef f ecti veness of treatments.

  • Nipigon Bay Area of Concern Status of Beneficial Use Impairments September 2010
    Nipigon Bay Area of Concern Status of Beneficial Use Impairments September 2010 Nipigon Bay is in the most northerly area of Lake Superior. The Area of Concern takes in a large portion of Nipigon Bay and the Nipigon River, the largest tributary to Lake Superior, and the communities of Red Rock and Nipigon. There are Ontario Power Generation dams on the Nipigon River for the generation of hydroelectricity. The area supports a variety of wetlands and bird populations, including one of four known pelican colonies in Ontario. The watershed forests on both sides of the Nipigon River have been allocated for forest harvesting. Environmental concerns in the Nipigon Bay Area of Concern are related to water level and flow fluctuations in Lake Nipigon and the Nipigon River from the generation of hydroelectricity. These fluctuations affect stream bank stability, sediment load and fish and wildlife habitat. Other concerns include the accumulation of wood fibre, bark and other organic material from past log drives, and effluent discharges from a linerboard mill (which closed in 2006) and the municipal sewage treatment plants in Nipigon and Red Rock. PARTNERSHIPS IN ENVIRONMENTAL PROTECTION Nipigon Bay was designated an Area of Concern in 1987 under the Canada–United States Great Lakes Water Quality Agreement. Areas of Concern are sites on the Great Lakes system where environmental quality is significantly degraded and beneficial uses are impaired. Currently, there are 9 such designated areas on the Canadian side of the Great Lakes, 25 in the United States, and 5 that are shared by both countries. In each Area of Concern, government, community and industry partners are undertaking a coordinated effort to restore environmental quality and beneficial uses through a remedial action plan.

  • Great Lakes Water Quality Board Position Statement on the Future of Great Lakes Remedial Action Plans
    WQB Position Statement - Future of RAPS Page 1 of 11 GREAT LAKES WATER QUALITY BOARD POSITION STATEMENT ON THE FUTURE OF GREAT LAKES REMEDIAL ACTION PLANS SEPTEMBER 1996 Introduction It has been over ten years since the Parties and Jurisdictions committed to the development and implementation of Remedial Action Plans (RAPs) to restore all uses in Great Lakes Areas of Concern. Recently, federal, state, and provincial budget constraints have resulted in less support for RAPs and public advisory committee (PAC) activities. Further budget cutbacks are anticipated. Numerous RAP stakeholders and many PACs have indicated that further progress will be difficult. In light of the fact that the Great Lakes Water Quality Board (WQB) was the originator of RAPs, that the WQB is the principal advisor to the International Joint Commission (IJC) on water quality matters, that the WQB is charged with assessing the adequacy and effectiveness of Great Lakes programs, and in response to concern for recent government cutbacks in RAP funding, the WQB has prepared this position statement on the future of RAPs based on its practical experiences over the last 11 years. This WQB position statement will review the history of RAPs, address current RAP funding concerns, and provide practical advice on sustaining RAP processes and ensuring continued progress toward the goal of restoring all uses in Areas of Concern. Water Quality Board Historical Perspective on RAPs The concept of RAPs originated from a 1985 recommendation of the WQB (WQB 1985). The WQB found that despite implementation of regulatory pollution control programs, a number of beneficial uses (e.g., unrestricted human consumption of fish, successful reproduction of certain sentinel wildlife species, fish and wildlife habitat) were not being restored, and recommended that comprehensive and systematic RAPs be developed and implemented to restore all beneficial uses in Areas of Concern.

    Biological Services Program FWS/OBS-82/52 SEPTEMBER 1982 ATLAS OF THE SPAWNING AND NURSERY AREAS OF GREAT LAKES FISHES Volume II - Lake Superior Great Lake - St. Lawrence Seaway Navigation Season Extension Program Fish and Wildlife Service Corps of Engineers U.S. Department of the Interior U.S. Department of the Army The Biological Services Program was established within the U.S. Fish and Wildlife Service to supply scientific information and methodologies on key environmental issues that Impact fish and wildlife resources and their supporting ecosystems. The mission of the program is as follows: o To strengthen the Fish and Wildlife Service in its role as a primary source of information on national fish and wild- life resources, particularly in respect to environmental impact assessment. o To gather, analyze, and present information that will aid decisionmakers in the identification and resolution of problems associated with major changes in land and water use. o To provide better ecological information and evaluation for Department of the Interior development programs, such as those relatfng to energy development. Information developed by the Biological Services Program is intended for use in the planning and decisionmaking process to prevent or minimize the impact of development on fish and wildlife. Research activities and technlcal assistance services are based on an analysis of the issues, a determination of the decisionmakers involved and their informatlon needs, and an evaluation of the state of the art to identify information gaps and to determine priorities. This is a strategy that will ensure that the products produced and disseminated are timely and useful.
