Not quite. They did start with pinks, that's correct. They were very successful in restoring a good run of pink salmon. Pink salmon can become very abundant very quickly, because they have a fixed two-year life cycle.
Essentially what they did is restore the ecosystem first, so it's certainly a model in that sense. They protected the habitat, they provided the water, and they restored the ecosystem function by providing heavy nutrients to the river system. Some coho did come back naturally, and other coho—you saw the small hatchery—were supplemented. You made reference to the restoration biologist and the building of the kilometre-long side channel.
The productivity of coho in that river is abnormally high. The success is maintaining a habitat, restoring the ecosystem, providing the habitat expansion, protecting the water flow—all things that, if you think back on it, are kind of a natural progression. Their success was that they overcame the pressures around that stream. They protected the water, they worked with the community and the agricultural groups, and they put the whole picture together.
