I just received this photo from Steve Sintay. He had a very productive day at Ala Spit Thursday: half a dozen 18+" fish. It's exciting to know the Dollys are still hanging around. If you're looking for a quick winter trip, this could be your opportunity.
I've had luck on both incoming and outgoing tides. Both produce eddies that are good holding water. If the tide level is such that you see water flowing over what I call the eastern sub-spit, fish both upstream and downstream of it. Just like a rock in a stream, the spit can create a little cushion on the upstream side. Small baitfish imitations are my go-to flies in the winter.
