1)Fall is my favorite time to fish since I mostly fish for trout these days. The changing of the seasons on a crisp morning makes for an enjoyable day even if the fish are not behaving. Brown Trout begin to get active.
2)Winter - fishing in the snow, more solitude, Urban Trout progam (close to home trout fishing for me), and C/R season at the trout parks. Often very good trout fishing and it is often warmer in the water on those spring fed creeks.
3)Summer - active fish, longer days for fishing, hopper fishing, and low clear water for site fishing.
4)Spring - Fishing picks up for warm water species. Spawning bass and bluegill make for a great time on a fly rod. Nice to warm the bones after a cold winter. Streams begin to get crowded after the long winter.
