The Current Twists of Springbank Dam

Since last December, it is difficult to recall a week that has gone by where some sort of new major twist hasn’t happened with this story.  Late in 2015, the Thames River Anglers Association (TRAA) and the Ontario Rivers Alliance (ORA) brought together a coalition of 20 different organizations, representing over 250,000 members, to jointly sign on to two letters sent to the City of London’s Mayor and Council requesting decommissioning.

Hydro Impacts 101: The Trade-offs

Snip20151105_5

ORA’s report, Hydro Impacts 101: The Trade-offs, identifies some of the environmental impacts that can and do occur at dams and waterpower facilities. It will become clear that waterpower is seldom clean or green, and that some rivers should not be dammed at all. In addition, this Report recommends some ways of reducing the impacts, and of improving the regulatory process for waterpower in Ontario.  Read our report here…. Continue reading



Pan-Canadian Climate Action Plan – A Clean Energy Future

Twin Falls GS, Abitibi River

The hydro lobby is very powerful and deep pocketed, and has gone to great lengths to undermine and debunk studies that clearly demonstrate the significant contribution that reservoirs make to total world GHG emissions.[i]   Shifts in water temperatures, or the availability of fresh water due to climate change could lead to reductions in electricity production capacity in more than two thirds of the world’s power plants between 2040 and 2069, said a study from an Austrian research centre.  In fact, Keywan Riahi, Director of the Energy Program at the International Institute for Applied Systems Analysis says, “power plants are not only causing climate change, but they might also be affected in major ways by climate”.[ii]

Hydro Impacts 101 – The Trade-offs

MEDIA RELEASE
For Immediate Release:         5 November 2015

Hydro Impacts 101 – The Trade-offs

Significant environmental damage from hydroelectric power generation has been ongoing for many decades in Ontario and in other locations throughout the world, yet the public has been led to believe that it provides a clean and green source of energy because there is no smoke, no ash, and no radiation. Indeed, some mistakenly think that all hydro contributes positively to the climate change issue.  “This report will help to set the record straight on just how clean and green waterpower really is”, said Linda Heron, Chair of the Ontario Rivers Alliance (ORA).

The Bala Portage – Duty to Consult – Wahta Mohawks

Bala Falls Portage

The Wahta Mohawks (formerly the Mohawks of Gibson)  arrived in Muskoka in November of 1881 using what is now called the Bala Portage – which has always been south of the Bala North Falls.  Historical documents clearly show that other First Nations in the area used this Portage prior to this.

Transportation by water and portaging is traditionally and culturally important to all First Nations, and it is disrespectful that we were not informed of the impact on the Bala Portage by this proposed project.  We plan on raising this issue with our political representative organizations including the Iroquois Caucus and Chiefs of Ontario.

We therefore hereby give notice that the communications and information the Wahta Mohawks have received concerning this proposed project have been completely inadequate, and the “Duty to Consult” has not been fulfilled.

New global warming culprit: Methan emissions jump dramatically during dam drawdowns

Source:  Washington State University

Researchers have documented an underappreciated suite of players in global warming: dams, the water reservoirs behind them, and surges of greenhouse gases as water levels go up and down. In separate studies, researchers saw methane levels jump 20- and 36-fold during drawdowns.
