Maybe one thing we have to consider is that each river has a unique run. The Tacoma run is to the Puyallup River so perhaps the salmon get into the river and to their spawning grounds a bit earlier than other river systems. They would spawn earlier and then in turn maybe return earlier. There is also a sizeable run to the Nisqually River projected this year and we have yet to see how quickly they will return since there has not been any sizeable run there until two years ago. I'm no biologist but that might be a reason why the fish show in the South Sound area earlier than the Northern rivers. It's kind of fun trying to guess what's going on and it shows the interest that has been growing over the years for this fishery. It gets more highly anticipated each two year cycle. People are already jumping out of their skin and we are at least a month away. It is a great fly fishing opportunity, however, so it's easy to see why we all get jacked up about it. Whether you retain and eat or catch and release, it's hard to beat this run on a fly rod every two years.
