Thank you. It's a great question. The fundamental questions around passage always have to do with the nature of the high head, so it's “Was there passage there prior to the establishment of the dam?” If there was, now that we are in the regulatory regime that we are, I think our delegation stated that we are happy to work within the Fisheries Act as it stands. That may include passage. I lived in New Brunswick for a year, and the issues with some of these east coast streams are invasive species like striped bass or smallmouth bass in the lower reaches of the river. Do we want those species up with the native species above the dams? We have to ask that question.
Then if we do decide to do passage, what is the level of effort required to maintain the ecological integrity, both upstream and downstream of the facility? Would that be physical sorting of fish as they come into the fishway, pushing the non-ideal fish back downstream and allowing the native, ideal species to come back upstream? There are instances where this is in place in the United States. However, there's a lot of intensity when it comes to that type of approach.
