The Report recommends the following: Construction Phase: o Avoid the Angler Internment Camp; . Prohibit use of ATV trail west of the existing Hydro One transmission corridor as a temporary access road. o If this section of trail must be used as an access road, the following actions should be prohibited: . Improvements beyond basic re-surfacing; . Excavation; and . Removing existing access road infrastructure. o If cultural material such as artifacts are found while making improvements to the trail or during use of the temporary access route, implement the Project Discovery of Heritage or Archaeological Resources Contingency Plan. o Site plan control and communication; o The Angler Internment Camp site should be clearly marked on project mapping and communicated to all project personnel for avoidance during construction phases of the Project. Operation Phase: o Site plan control and communication; . The Angler Internment Camp site should be clearly marked on project mapping and communicated to all project personnel for avoidance during operation phases of the Project. o If cultural material such as artifacts are found while making improvements to the trail or during use of the temporary access route, enact the Project Discovery of Heritage or Archaeological Resources Contingency Plan In addition, a contingency plan has been developed in case of unexpected discoveries of cultural heritage resources not previously identified and is discussed in section 8.1.5 of the report.

In December 2015, NextBridge Infrastructure LP retained Golder Associates Ltd. (Golder) to provide a number of services for an Environmental Assessment (EA) of the East-West Tie Transmission Project, a proposed 450-km long double-circuit 230 kV transmission line in northwestern Ontario between the Lakehead Transformer Station in the Municipality of Shuniah, near the City of Thunder Bay, to the Wawa Transformer Station located east of the Municipality of Wawa. To address potential impacts to cultural heritage resources, Golder provided a preliminary screening and assessment of the effects for the Environmental Assessment Report for the East-West Tie Transmission Project (Section 16: Cultural Heritage Resources), then conducted a Heritage Impact Assessment (HIA) for cultural heritage resources identified during the preliminary screening. During the preliminary screening, seven potential cultural heritage sites were identified to be at risk of direct impact. These included six mines and quarries, and an internment camp for Japanese-Canadians and German Prisoners of War established during the Second World War known as the ‘Angler Internment Camp’. During preparation of this HIA, an eighth cultural heritage resource was identified —the Aguasabon River and Hays Lake near the community of Terrace Bay. Evaluation of these sites using the criteria prescribed in Ontario Regulation 9/06 determined that: The Gananoque Vein Gold Mine and Halonen Fluorite Mine could not be evaluated since the sites could not be found within the Project Local Study Area. It is possible the sites are not in the LSA and/or the sites have been reclaimed by the forest. The Molybdenite Lake Prospect and Bishop Lead Occurrence mine sites are not of cultural heritage value or interest since they do not meet any criteria of O. Reg. 9/06; The Angler/Petrunka and Mackenzie Quarry sites are not of cultural heritage value or interest since they do not meet any criteria of O. Reg. 9/06; The Angler Internment Camp is of cultural heritage value or interest since it meets six criteria of O. Reg. 9/06; and The Aguasabon River and Hays Lake is of cultural heritage value or interest since it meets two criteria of O. Reg. 9/06. ii July 13, 2018 1536607-2000-R01 Golder determined that the Project will not have an adverse direct or indirect impact on the cultural heritage value of the Aguasabon River and Hays Lake. However, this HIA also determined that, without mitigation measures the Angler Internment Camp is at risk of direct adverse impact from the Project. Golder therefore recommends the following actions prior to and during construction. Avoidance: Project operations should avoid the Angler Internment Camp; Site plan control and communication: The Angler Internment Camp should be clearly marked on project mapping and communicated to all project personnel for avoidance during construction; and, Monitoring and contingency planning: Periodic monitoring should be conducted during construction to ensure that the Angler Internment Camp is being avoided, and the ‘Discovery of Heritage or Archaeological Resources Contingency Plan’

  • Characterizing the Flow Regime in Brook Trout (Salvelinus Fontinalis) Incubation Habitats and the Implications for Management in a Hydro-Regulated River
    Characterizing the flow regime in Brook Trout (Salvelinus fontinalis) incubation habitats and the implications for management in a hydro-regulated river by Stephen Slongo A Master’s thesis presented in Partial fulfillment of the requirements for the Degree of Master of Science in Forestry Faculty of Natural Resources Management Lakehead University Thunder Bay, Ontario January 2018 1 Abstract Hydropower accounts for more than one third of Ontario Power Generation’s electrical production. Hydroelectric development often occurs on rivers that also support recreational fisheries. The construction and operation of dams, diversions and generating facilities unavoidably influence the ecological function of rivers. The Aguasabon River is a northern Canadian Shield river with major developments for water diversion, storage, and power generation. This river offers opportunity to examine the importance of vertical flows through the substrate at a Brook Trout (Salvelinus fontinalis) spawning area. The vertical and horizontal hydraulic gradients and subsequent water temperature changes are the subject of this study. Piezometers were used to monitor the river and subsurface water levels near Brook Trout redds during the spawning and incubation period under normal and increasing discharge conditions. The Brook Trout spawning area in the Aguasabon River experienced upwelling conditions for the entire monitoring period (Oct 28th, 2016 – Jan 13th, 2017) before water release at the Long Lake Control Dam (LLCD). Hyporheic temperatures declined gradually, remaining >3.7 °C. The river temperature in the winter before water release was 1.5 °C. Rapid increase in water level after discharge from above the LLCD resulted in the reversal of flow in the hyporheic zone.

  • Task 3 Neil Fulton
    REPORT ON POTENTIAL MEASURES TO ALLEVIATE PROBLEMS CREATED BY CtIFWNT HIGH LAKE LEVELS TASK 3 DIVERSIONS MANAGEMENT ,.l -. TO THE INTERNATIONAL JOINT CCXMISSICPJ FROM TASK GROUP MEMBERS GERALD MACMILLXY DON LEONARD RM; GOLDING BILL DALEY MAC ODELL BILL ERDLE PETER YEE . NEIL FULTON SEPTEMBER 1987 EXExmTIVE SUMMARY The Governments of Canada and the United States requested, in August 1986, that the International Joint 'Commission study methods of alleviating the adverse consequences of fluctuating Great Lakes water levels. Part of this study entailed an immediate short-term investigation of methods of alleviating the present high water level crisis. One of the elements of the short-term investigation was a study of diversions management and the results are contained herein. The theoretical maximum flow through the Welland Canal in an extreme crisis situation was estimated to be 12,000 cubic feet per second (cfs). The most significant physical impacts of this maximum flow would be the complete disruption of navigation between Lake Ontario and the upper lakes and the possibility of major damage to the canal itself. A reduction in Lake Erie levels of 1.3 inches would be achieved. The Ogoki and Long Lac Diversions can be closed completely but, because of significant social impacts associated with the closure of the Long Lac Diversion, a.scenario involving a combined annual diversion flow of 800 cfs was investigated to determine the benefits foregone by maintaining the log-driving operation from Long Lake. The most significant physical impacts were the direct loss of 2,500 jobs in the Terrace Bay - Longlac area resulting from the closure of the Kimberly-Clark pulp mill in Terrace Bay due to complete closure of Long Lac Diversion, and the reduction in livelihood and alteration in way of life for local populations associated with the closure of both diversions.

Consider Year 1 as the present year. All values are in the thousands, and the interest is 8% simple interest compounded annually. Year 1 Year 2 Year 3 TOTAL $100 000 $150 000 $200 000 $450 000 The present value cost of Year 1 = $100 000 The present value cost of Year 2 = $150 000 divided by 1.08% = $138 889 ($138 889 invested 8% simple interest for one year = $150 000) The present cost of Year 3 = $200 000 divided twice by 1.08% = $ 171 468 (This means that $171 468 invested at 8% simple interest will be worth $200 000 after two years) Therefore, the present value cost of $450 000 in this example is $410 357 $100 000 + $138 889 +$171 468 = $410 357 Impacts of Dams Dams change behaviour of rivers- sediment load settles behind a dam. Downstream, water released through outlet pipes causes channel erosion Farther downstream, the opposite can occur with silt forming islands and sandbars.
