Without getting into a deep academic exercise, because I'm sure that's not what you're looking for, broadly, it's important to recognize that the flood will have had some negative effects. It will also have had some positive effects, if flooding is a natural thing, even though the one that occurred last November was substantial and relatively unprecedented, at least in our modern reported history.
There will be a need to look at critical areas for salmon, particularly in areas that might be cut off or stranded that could be reconnected, or areas that have been unduly changed, because of the interaction of the natural environment and human infrastructure.
There will likely be a need to go and rebuild, or support, accelerated recovery of critical habitats. For instance, the Coldwater and Nicola areas are really challenged in the summertime, especially during drought with high water temperatures. At present, many of the deeper holding pools and holes that salmon and steelhead would rely on at certain times of the year seem to have been filled in, so there might be a need to go to find critical habitat areas like that. Nature will recover them on its own, but salmon and steelhead are in trouble. We probably need to do things to accelerate some of that recovery.
