Stillwater Retrieves
Overall, the movement of these aquatic insects is slow or at best they can move at a moderate speed for a very short distance. Some, like midges, only rise or elevate through the water column. It can be hard for many anglers to slow their retrieves down and then maintain the slower pace long enough to effectively retrieve the entire length of a cast.
The strip and hand twist are two basic retrieves that all stillwater fly fishers should be comfortable using with the various food sources being imitated. The strip retrieve is as simple as it sounds and it is the basic retrieve for almost all fly fishing situations. The rod hand lightly pinches the fly line between the thumb and index (first) finger while the retrieve hand uses the same two fingers to pull or strip in a set amount of fly line. It takes a lot of practice to conduct a 4 inch slow strip retrieve cast after cast for several hours but if that is how the damselfly nymphs are swimming then it is best to go with the flow. Without patience and practice, those 4 inch strips soon become 8 then 12 inch pulls! How slow is slow? For instance, to imitate a slow 2 inch strip retrieve count up to 2 seconds while the 2 inches is being retrieved. A fast 4 inch retrieve would count between 1 and 1.5 seconds per strip. Caddis pupa probably swims the fastest of these aquatic insect food sources. A fast 6 inch strip retrieve should take approx. 2 seconds to complete.
The hand twist is the other basic retrieve that should be mastered by all stillwater fly fishers. This is a busy retrieve, meaning that it requires more hand movement while at the same time helps to slow down the retrieve. The other advantage of this technique is that the angler has more control over the retrieve as the retrieve hand is always in contact with the fly line. The rod and retrieve hand start off in the same positions as the strip retrieve. The fly line is pulled down by the thumb and index finger of the retrieve hand while at the same time rotating the retrieve hand wrist outward thus leaving an open palm. The fly line is then hooked around the bay finger of the retrieve hand and then brought back to the thumb and index finger. This completes a full hand twist. As the manoeuvre is repeated coils of line will collect in the palm of the retrieve hand. It is best to release the fly line after 2 or 3 coils have accumulated. The hand twist is certainly the preferred retrieve to use when imitating the midge pupa either rising up through the water column or very slowly moving the pupal pattern horizontally through the water. In these instances a complete hand twist could take upwards of 8 seconds to complete.
The strip and hand twist retrieves will allow the angler to match the movement of these essential stillwater food sources. It can also be beneficial to impart a bit of irregular movement to your fly as it is being retrieved. In other words, try adding several very short, quick one inch strips in succession during any normal strip or hand twist retrieve. I routinely mix in 3 or 4 of these quick strip tactics into any stillwater retrieve. Sometimes this off tempo movement is enough to commit an otherwise slightly skeptical trout into taking the fly.
Wind drifting from an anchored boat is also an effective technique to present flies being fished with floating fly lines. It is used most commonly with mayfly nymphs, damselfly nymphs, caddis pupa and midge pupa. Although technically not a retrieve, wind drifting takes advantage of gentle wind conditions to naturally move the sunk fly in a subtle undulating motion horizontally through the water column. A cast is made sideways or perpendicular to the direction of the wind. A large arching bow develops in the fly line as the waves carry it downwind. The length of the leader and weighted versus un-weighted flies determine where in the water column the fly will travel. Make sure the rod is secure when using this tactic!
It takes practice in order to get comfortable with these retrieves. While on the water watch for the real insects and note their swimming and movement patterns. That will be the best check as to how realistic your retrieves are being conducted.
