Barracuda,
Pocket water small streams are by far my favorite type of fishing. Accuracy and inovation are at a premium here, and losing flies to stuff around and above the water is commonplace, even if you are ‘good’ at this type of fishing.
If there ain’t room to cast, then there isn’t room to cast. By ‘cast’ I mean the classic overhead or even the old standby ‘roll’ cast. Both of these require a minimum amount of ‘room’ either above, in front of, or behind the fisherman.
Still, you can find a way to get fly onto the water. Little ‘flips’ with a minimum of line and the leader. Flicking the fly with just the leader out. Dapping the fly onto the water just at rod length distances. Bow and arrow casts are also a good option. Even moving upstream and letting the current carry the fly to fish as you feed the line out.
And, while a shorter rod requires less ‘room’ to make a regular ‘cast’, sometimes a longer rod will work better in these obstructed conditions simply because of it’s longer ‘reach’. It’s a trade off, certainly, but your 8’ rod is certainly adequate for this type of fishing with a bit of practice.
In these condtions having enough line out to ‘load’ a rod is impossible. The slower the action of the rod, the easier it will be to get some enertia behind any of those little ‘flips’ and ‘flicks’ that you will have room for. Cane rods shine for this. They have their own ‘mass’ and will load and unload gently and predictably regardless of the amount of, or lack of, line out the tip.
Understand, though, that this method of presenting a fly is a learned skill like any other, and you can learn to do it with ANY rod you choose. They all will work.
While figuring all this out, just be prepared to go through a bunch of flies. Don’t be afraid to try to get a fly into anyplace you can see. If you can draw a line from the rod to the spot, then, theoreticly, you can get a fly there. Sometimes you’ll miss, sometimes you’ll get hung up, but sometimes you’ll be amazed at what you CAN do, and the fish you’ll find in those tight spots.
On really obstructed streams, where I know that ‘casting’ will be unlikely, I prefer a soft 9’ 3 wt. rod. I can stick this rod ‘through’ piled brush, reach over log jams, and flick a fly to a about 15-18 feet without having to do much more than roll my wrist. Having a nice fish take a fly at rod tip length where you can see it, and THEN trying to wrestle it through all the stuff between you is an awesome experience.
If there may be some casting room, I’ll opt for a 6’ 6" 2 wt., which is a great little close quarters casting tool. A buddy of mine borrowed it one day and landed a 23 inch brown on it. Loads of fun.
I even have a little 4’ 6" rod that I’ll use on some little streams where I don’t have to walk in too far (It’s one piece), that’ll let me roll a cast anyplace I can stand. Not far, but it will cast.
Gotta love those tight little streams. Each fish is an obstacle overcome or a problem solved.
Good luck!
Buddy
