In British Columbia there is a proposal to build a new dam at “Site C” to help generate affordable clean energy to the region. It sounds like a wonderful idea, but with any project of this size there are certainly downsides to consider as well. In particular, according to this report(PDF):
The District of Hudson’s Hope, a community of 1,100 people in the heart of the Peace River Valley, will be impacted more than any other municipality by the proposed Site C dam.
The video below explores the project, hears from involved parties, and makes great use of Google Earth to add context to the area and some rough looks at what the result of the dam would look like.
Details on the project can be found at hudsonshope.ca, though their short-term focus (understandably) has shifted to wildfires in the area. You can also view this PDF or this article on Common Sense Canadian to learn more.
