It can work, but to get the right rain to bring in enough fish to make it worthwhile might be pushing the end dates for bear season. I seem to remember last year that the rains didn't come until early Nov and the salmon only came in so-so. It also occurs during elk season and quite a few guys were disappointed (even in the last couple rainy years) at the lack of salmon that did return (silvers) and were in the creeks during mod elk season.
