While there is usually a really good bite right before inclimate weather, Steelhead bite well after a good rain and water levels are dropping back down.
Weekly Report: 01/06/25 - The current conditions are cold and snowy. Looking at the future forecast, that does not look to be changing any time soon. River conditions on the tribs are slushy with some shelf ice forming as well. With the water being a little high and ice setting in, fishing conditions are less than ideal. If you are brave enough to tough out the conditions, you may find a little open water if you look. With fishing pressure sure to lighten with the cold the fish may be willing to take any flies they see as well. Its good time to start swinging some nymphs with your egg patters. If you don't like fishing in slush and or fighting ice in the guides, it's a really good time to get some time on the tying bench and stock the fly boxes up for the spring runs!
