The upper spokane is pretty warm now, but you can still find some smallmouth to play with. Going early or late is preferable than mid day, but swinging small streamers can be fun. The closer to downtown you get the colder the water is due to the aquifer so if you want some trout you must go down river and explore. Streamers are still a good way to cover water, but tandem nymph rigs work well too. Small caddis and emergers can find some picky fish if you see them surfacing but be patient and make your casts count.
