My advice would be to make the service area as large as possible and to take into consideration what people want in terms of fisheries. When I look at Alberta, for example, the mitigation I saw there in the oil sands was miles away from most communities, whereas southern Alberta is starved for fish, given how many people there are and the lack of water bodies.
If you also use fish production as a metric in addition to habitat and are very flexible, you have the potential to unleash millions of proponent dollars to do some very creative fish enhancement in places where people actually want it to be done.
If you could make a comment about what I just said, I'd appreciate it.
