Hydroelectric is not emission-free or clean. A Washington State University study on the effects of damming conducted in a central European impounded river revealed that the reservoir reaches are a major source of methane emissions and that areal emission rates far exceed previous estimates for temperate reservoirs or rivers. It showed that sediment accumulation correlates with methane production and subsequent ebullitive release rates. Results suggested that sedimentation-driven methane emissions from dammed river hot spot sites can potentially increase global freshwater emissions by up to 7%. Hydroelectric facilities need to acknowledge and account for the associated GHG emissions they produce.

It is challenging to understand the logic of a November 2021 CBC article that reports, “The Nature Conservancy and the World Wildlife Fund are two environmental groups that oppose new hydro dams because they can block fish migration, harm water quality, damage surrounding ecosystems and release methane and CO2. But they say adding turbines to non-powered dams can be part of a shift toward low-impact hydro projects that can support expansion of solar and wind power.” Whether it’s a new dam or an older retrofitted dam, they will result in the same negative impacts and produce the same amount of methane for 70 to 100 years or more.
Protected areas are a proven means of conserving biological diversity and mitigating the impacts of climate change, two of the greatest challenges we face as a society. They also enjoy broad public support. For example, a 2018 national survey conducted by IPSOS found that 93 percent of Canadians believe that protected areas are necessary. Similarly, a 2019 national survey conducted by Abacus Data found that 88 percent of Ontarians support protecting or conserving more natural spaces and 91 percent supported Canada’s 2020 protected areas commitment. There is no doubt where the public interest lies on this issue.
The West Credit River subwatershed supports headwater tributaries of the Credit River and is considered the crown jewel of coldwater Brook Trout fisheries in southern Ontario. The entire footprint of the Project, including the network of underground sewers, will result in numerous crossings of first, second and third order streams. Additionally, the West Credit River feeds into the main Credit River at the Forks of the Credit Provincial Park. This area is part of the UNESCO Niagara Escarpment World Biosphere Reserve (Reserve), home to several sensitive fish species, including the endangered Redside Dace and Atlantic Salmon. Atlantic Salmon, historically extirpated, are being reintroduced as part of the broader Lake Ontario Atlantic Salmon Recovery Program. This Reserve is within 1 km downstream of the Project’s effluent discharge, and Redside Dace (Schedule 1, Species at Risk Act, 2002), are known to occupy the West Credit River within 4 km downstream of the effluent diffuser.
Finally, the West Credit River is a headwaters tributary of the Credit River and is considered the crown jewel of coldwater brook trout fisheries in Ontario. This fishery significantly adds to the economic and social fabric of the province, with Ontario fisheries contributing a total of approximately $2.5 billion annually to the provincial economy. MNRF’s own documents predict that climate change will reduce the number of watersheds in Ontario with brook trout by 50% by 2050.
The American Eel Needs Your Help! You have an opportunity to support the recovery of a species that has declined by 99% of its original population, has been completely extirpated from extensive areas of its native Ontario range, and is in steep decline where it still exists. The Ministry of Natural Resources and Forestry has prepared a Draft Government Response Station for the Recovery of the American Eel in Ontario, and you have until January 11th to sign the Petition below. More information can be found here. To add your own comments just click on the letter and type. Thank you for your help! Continue reading

Conservation organizations call for end to delays in implementing recovery actions for endangered American Eel
One of the most popular energy sources for Canada and globally has been hydroelectric power generation, and the provinces of Ontario, Quebec, Manitoba, and British Columbia are big fans of this particular energy source. One of the main reasons it is so popular is due to the abundance of water in Canada in the form of lakes and rivers that run throughout the provinces.
There was an article by the Montreal Gazette written back in 2011 that took a look at the Romaine River in Quebec and how it was about to turn into one of the biggest construction sites in Canada with the installation of 4 dams, 7 dikes, several large canals, and 279 square kilometers of reservoirs, all at the approximate cost of around $8 billion. What decision makers in Quebec failed to realize or choose to ignore is that harmful greenhouse gas (GHG) emissions are generated by reservoirs and they can be extensive and very damaging to the climate.

Take a 3D Fly-over along the entire Ontario length of the existing TransCanada pipeline slated for conversion to bitumen transport. Every stream, river and lake that the line bisects is identified and displayed. It certainly provides a birds-eye view of what could be lost should a leak occur. This will graphically explain why ORA has applied for Intervenor Status in the National Energy Board hearings.

The Demise of American Eel in the Upper St. Lawrence River, Lake Ontario, Ottawa River and Associated Watersheds: Implications of Regional Cumulative Effects in Ontario
Abstract.—American Eel mortality has increased substantially over the past century due largely to significant cumulative effects of fishing and fish passage through hydro-electric turbines across their range. Nowhere has this been more pronounced than in waters of the St. Lawrence River, Lake Ontario, Ottawa River and associated watersheds. We illustrate this by examining the cumulative effects of hydroelectric facilities on eels migrating downstream through the Mississippi River and Ottawa River, and outline further impacts eels encounter en route to spawn in the Sargasso Sea. The probability of a mature female eel surviving its emigration through the Mississippi and Ottawa River to the upper St. Lawrence River is estimated to be as low as 2.8% due to turbine mortalities alone (2.8–40%). Mortality risk increases as the eel attempts to run the gauntlet of fisheries in the lower St. Lawrence River and the probability of out-migration survival is estimated to be as low as 1.4%. Some mortalities could be mitigated through improved application of existing laws, development of policy requiring consideration of cumulative effects and improved integration among program areas responsible for sustainable management of fisheries, biodiversity, dams and hydro-electric facilities. We recommend changes to policy, procedures and internal organizational structures provided with clear directions, and call for increased accommodation of Aboriginal perspectives.
