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: 04/21/25 - I have been keeping up with the posts online from several fishing locations. From everything I have seen the fishing has been good just about everywhere. Some Steelhead are still in the tributaries and the Small Mouth fishing in the tribs has been really hot! My source on the White Bass says there are some in the creeks, but the big runs have not started yet. I have also seen some good reports out of Pennsylvania and the Brook Trout fishing is really good right now if you are willing to do a little blue lining. The Panfish bite should be hot as well with most if not all of them sitting on beds and aggressive. A bull Bluegill on the 2 weight can be a ton of fun! The only location that I have not heard about the clear fork. I assume that it too is fishing quite well at the moment with hatches starting to pick up. If you are ready to dust off the gear from the winter, now might be a really good time to go get the waders wet!
