History of The Griffins Gnat in Colorado

The Griffith's Gnat is a popular fly pattern in Colorado for trout fishing. Designed to imitate a small black insect or midge, it is used as a dry fly to imitate an adult insect on the water's surface. Anglers typically use a floating line and a long leader for the best presentation. It is effective in slower, flat water such as riffles and seams, where trout tend to gather. Various techniques like dead-drift presentation or slight twitches can be employed to mimic the movement of a struggling bug. It is important to closely watch for any trout taking the fly.

To summarize, the Griffith's Gnat is a versatile fly pattern that imitates small insects on the water's surface. It is best used as a dry fly in slower waters and can be effective in Colorado for trout fishing. Remember to use a floating line, long leader, and employ proper techniques to increase your chances of success.

Fly Fishing the Griffins Gnat 

Tackle and Setup: Make sure you're using a floating line and a leader that's long enough to give you a good presentation. A longer leader, around 15', can work well with a 9' rod.

Presentation: Look for those spots where trout like to hang out, like riffles and seams. Cast your fly there and let it drift naturally with the current. Keep a close eye on any movements that might signal a trout taking the fly, and be ready to set that hook!

Techniques: Try using a dead-drift presentation to mimic the natural movement of insects on the water. You can also give your fly a little twitch or skate it lightly to imitate a struggling bug if the trout seem picky.

Water Conditions: The Griffith's Gnat can work well in slower, flat water. It sits low in the foam, making it look like a tempting snack for hungry trout.


Tying The Griffins Gnat Fly

Materials Needed

To tie the Griffins Gnat fly pattern, you will need the following materials:

  • Size 18-22 dry fly hook
  • Black thread
  • Black or gray dubbing
  • Grizzly hackle fibers
  • Fine black or gray thread for the body
  • Head cement or super glue

Make sure you have all these materials ready before you begin tying the fly.

Step 1: Preparing the Hook

  1. Start by placing the fly hook securely in your vise.
  2. Attach the black thread to the hook shank and make a few wraps to secure it.
  3. Trim off any excess thread.
  4. This will serve as the foundation for the body of the fly.

Step 2: Wrapping the Body

  1. Take a small amount of black or gray dubbing and dub it onto the thread.
  2. Wrap the dubbed thread along the hook shank, creating a smooth and tapered body.
  3. Make sure to leave some space at the front of the hook for the wings and hackle.

Step 3: Adding the Wings

  1. Select a small bunch of grizzly hackle fibers.
  2. Tie them in at the front of the hook, creating wings that extend slightly past the hook bend.
  3. Secure the wings with several wraps of thread and trim off any excess.
  4. Make sure the wings are evenly spread and facing forward.

Step 4: Finishing Touches

  1. Apply a small amount of head cement or super glue to the thread wraps behind the wings.
  2. This will help secure the wings in place.
  3. Make a few more wraps of thread to ensure everything is secure.
  4. Trim off any excess thread and apply a final coat of head cement or super glue to the thread wraps for added durability.
  5. Allow the fly to dry completely before using it for fly fishing.
