Thank you for the question. I can answer that.
Not every facility would have fish passage included within it, but when we're looking at the question of fish passage in the hydro power facilities, whether it's a storage reservoir or a run-of-river operation, it really has to be looked at in the context of the environmental assessment for each project that is done. When exploring fish passage, sometimes the answer could be fish passage, if necessary, but not necessarily fish passage on every facility, always owing to the unique nature of each facility in question. For a large number of facilities already built in Canada it's good to mention that they are high-head facilities, as we call them. That means there is a large elevation drop between the reservoir and the power house. In such areas or instances, upstream fish passage in many cases wasn't possible to begin with, simply because of the elevation change. Obviously, a facility like that would not require fish passage, because it would make a change to the natural environment that was there.
In other cases, we've seen a desire to not include upstream fish passage because of invasive species issues. In some cases, you want to limit the passage of some of the new invasive species downstream, up river. I would just mention that in some cases fish passage is warranted and is a good idea for the local ecosystem, but in other cases, it isn't. We really need the flexibility on a site-by-site basis for each project to be able to determine if it's appropriate and where it should be built.
