10/19/2013 9:25:00 AM1. there are some spots of the river that are a bit low and fish wont move up until there is enough water
2. it push minerals from the soil down river which salmon can sense or "smell" and make their way back home
3. for anglers, it also makes the river high which means these "holes" that we talk about hold fish in them until they are ready to head up river.
There are many more reasons why rain is good but these are the ones I am aware of.
