Yup, with a fly casting bubble. It's clear so trout and other fish have a harder chance seeing it, can be filled with water for loger cast. They can be bought at Cabelas and other sporting stores.

I have never heard of the bubble thing, but it sounds kind of cool... But I have heard of the fly and bobber tactic and have seen someone doing it before. I have never done it, but i know it works.

I have done quite a bit of steelhead fishing with a spinning rod. I use four or six pound main line with a five foot 2# tippet. I use a small pencil sinker attatched to the end of the main line on a tiny swivel. I use it in fast water of 3-15 foot depth. I often use a wooley worm. You cast upstream and let the fast water drift the pencil sinker over the rocky bottom. The fly drifts ahead of the sinker just above the bottom and around the stones. I use a 11 1/2 foot noodle rod with that rig to take the shock when a 15 pound trout catches the current and makes an arial run. You lose a few but they are a riot to catch. It really helps at times to get right down on the bottom where they are hiding. If you are not familiar, a pencil sinker is a thin cylnder of lead almost like a skinny rubber worm with an eyelet at one end. It drifts over rocks and stones without getting caught. If it does hang up, you can usually free it with a gentle lifting of your rod tip. It is killer on trout hiding behind stones on the bottom.

Clear plastic casting bubbles work very well.

Yes, it works. Remember the weight of the fly line enables the long cast. Without it you must substitute a different kind of weight to enable the cast using the streamer of choice. The water filled clear plastic bubble is a winner.

Hey Dakota, same experiences here on the river bottom bounce you get from 3/16" "pencil lead." I encase it in a short length of rubber tubing. I found the Steelies liked that set up with Corkies or Okie Drifters. Then I saw a guy upstream substituting the Corkie with a streamer, and I haven't gone back since.

I used the fly and bubble method for years before I picked up fly fishing. A bubble half filled with water about 3' up from a dry fly does pretty well for top water fishing out here in our mountain lakes. With a water-weighted bubble you can really zing it too.

How to rig:
Small creek to medium size river;
Use a 1 1/4 inch plastic bubble (SouthBend makes a very inexpensive one) it has a hollow pin in it:
Brass snap swivel size 10, 11 or 12;
Take your line and run it through the narrow tip of bubble pin (the pin is tapered and if you closely you can see one end is smaller than the other end; A GREAT way to remember this is "The TIP of the ROD point to the TIP of the bubble pin" why is this important? First cast will release all the water out of the bubble--you will see it once you bring in back in for your next cast! Moving along
AGAIN, thread you reel line through the tip of the bubble and then attach to the snap swivel or barrel swivel if you have this type; either will work
Next, take 4-6 pound test and cut a piece the length of your rod end to tip and a minimum of 6 feet--this becomes import for on top of the water fly fishing.
Tie the leader to the snap end of the swivel (I use improved clinch knot) then other end attach a fly.
Make sure that the fly hook shank runs straight across (parallel) to the line of the leader adjust as need by holding the line and moving fly to "line up" straight. Now here comes the experience part to get it to the bottom of a large pool of water fill the water bobber completely -- leave no air in the bubble! Toss it at the beginning of pool and let in sink through, slowly lock the line by turning on your reel and pull it up then dip the tip of rod to allow it to sink again and pull up slowly, bring it to the surface. What you are doing is say hello to fish by allowing it to go by them then bringing it back past them, when you "dip the tip" you are allowing it to sink closer to them and then hang on as you allow the fly to rise to the surface! 80-90% of fish food is underwater. Adjust the amount of water in the bubble for depth if in shallow water and fish are on top feeding on surface feed. Add a split shot 2 feet below swivel to sink it to a certain level-- the deeper you want the fly to swim the closer the split shot to the hook -- no closer than 2 feet -- it can have the effect of spooking the fish -- one trick-- borrow some RED nail polish and paint the split shot. I went yesterday and with a fully loaded 1 1/4 water bubble I was pulling out 3 pound Brown Trout out of pool about 8 feet wide and 6-8 feet deep. It works I have fished major rivers using this rigging with success 90% of the time and rarely use bait anymore. It is safer than wading in rapid water where you don't know the layout of the water and in one spot you can reach more spots in less time than a typical fly rod. I can say this from personal experience having fished with both setups traditional fly rod and with spinning rig with the bubble=swivel-leader-fly setup. Trout are my main fish of choice. I like this time of year (Autumn) because the Brown Trout are very aggressive and fun to catch. After 40 years of fishing in this manner I honestly can say I have mastered many a trick using this setup. I do use my fly rod when I take out the canoe or the pontoon for 2 and fish in a total different manner. One last thought shorten the leader when fishing POOLS (under 6 feet) and longer when fishing lakes or rivers in the moving water (especially if the water is calm go longer). I use wet flies and nymphs (emergers)sub surface is easier for fish to find.
Hope this helps and enjoy fishing in this manner. And remember you have to believe that the fish are going to hit so be ready and let them hit the fly resist jerking to set the hook!
