Also, be sure to check out our Perfect Fly Hatch Charts for streams in Yellowstone Park. . New "Perfect Fly" Website Stream Section - Blacktail Deer Creek We recently added a new stream section in our Perfect Fly website for the Blacktail Deer Creek in Yellowstone National Park. This stream is located between Mammoth and Tower. The road crosses Blacktail Deer Creek not far beyond the Gardner River at the high bridge if you are headed East.
This is a rugged little stream but fairly easy to access in most places. It is best to go downstream a good distance and then fish back upstream in the creek bed. The fish will take just about any dry fly this time of the year, but if you use imitations of those insects hatching or about to hatch, you will increase your odds considerably. It's a small stream but it has a huge population and a large diversity of aquatic insects. Right now, terrestrials are popular for fishing Yellowstone National Park. They will also work on this little creek. Don't fish right under the bridge. That's my private hole.
This is a great little Brook Trout stream. You can fish it in either direction from the bridge, or downstream from the trailhead for the Blacktail Deer Creek Trail that takes you to the Yellowstone River. Here's our four page section on Blacktail Deer Creek.
