SPRING STEELIES

By John Nagy

Fly fishing the Lake Erie tributary streams in the spring is in a lot of ways a paradox of the winter steelhead season. To begin with, stream temperatures are pushed from the frigid low 30’s into the 40 degree F plus range. This causes sluggish steelhead already in the streams to become more active and aggressive.
Rising air temperatures and spring rains melt winter snow cover and stream ice resulting in higher flows. This, in turn, brings fresh runs of steelhead in from Lake Erie. Steelhead begin moving from their winter locations (deep, slow moving pools and eddies) to shallow gravel beds fulfilling their strong spawning urges. This usually occurs in late February and continues through April. Scientists have determined that this spawning behavior is triggered by a combination of two factors: stream temperatures (40 degrees F or above) and increasing “photo periods” or periods of light versus dark.
Locating spawning areas can result in some fantastic steelhead fly fishing during this time of the year. This is not only true for spawning steelhead on their beds but also pre-spawn fish located nearby and spawned out steelies (drop-down fish) heading back to the lake. Ideal spawning areas are basically riffles, which have large-size diameter gravel, are 1-4 feet deep, and have darker color bottoms. Next to these areas are usually deeper runs, pockets, or pools which harbor pre-spawn and post spawn fish, as well as fish that have been spooked off their beds.
Actual spawning involves a female steelhead moving into a spawning area and digging out a redd. She will do this by turning on her side and making powerful upsweeps of her tail in the gravel. The current washes away loose gravel until a saucer shaped hole has formed which will hold her eggs. Males will be attracted by this activity and begin competing for spawning rights, with the largest and most heavily kyped males winning out. They will use their superior power and large kypes (which are grown for this purpose) to drive inferior males from the redd. After the female drops her eggs, about 20 % of what she is carrying, the dominant male will fertilize them (sometimes one, or possible two, sub-dominant male will also participate), and the female moves immediately upstream to begin making another redd. The displaced gravel from this redd covers the previously fertilized eggs downstream. The female will continue this process until she is spawned out.
When you are fly fishing a spawning bed there are several things to keep in mind. If you don’t notice any spawning activity on the bed itself, blind fish adjacent deep-holding areas. As previously stated, these areas can hold steelies that are not in a spawning mode.
Fishing on the redds themselves has a simple strategy; fish for the males. They will be easy to distinguish from the females since they appear almost black while the females are bright silver. If you catch the female first, the males will quickly scatter. These aggressive males become very territorial and are not actually feeding, but will chase flies to dominate the redd.
Before fishing, position yourself slightly upstream of the redd and cast your fly so it reaches stream bottom as it drifts through. Mend your line to maintain a dead-drift and keep a tight line so you are able to quickly set the hook. Try to visually follow your fly through the redd so that you target the males and react quickly to their takes.
More often than not you won’t be able to see spawning fish very well on the bed. This is usually the result of spring run-off, which causes high, turbid water, or a spawning bed with a dark bottom. The dead giveaway though is the female as she turns on her side; the tail shakes giving flashes of silver, or gold in muddy water. Wearing polarized sunglasses on bright days is a tremendous help in seeing these flashes. Mentally mark this spot in the stream and fish to areas just downstream where the males will be holding.
Effective fly patterns for spring steelhead include yellow, white, and black Wooly Buggers, bright egg patterns (glo-balls, sucker spawns, scrambled eggs and blood dots), various streamer patterns like the Lake Erie Emerald Shiner and Clouser Minnow, Wooly Buggers, Spring Wigglers and bead-head nymphs (prince’s, black stoneflies and green caddis larvae).
Fly rods in the 9 to 10 foot range with medium to medium-fast actions are ideal for fishing egg patterns, nymphs as well as wooly buggers and streamers. Longer 10 ˝ foot fly rods (custom made from “noodle” spinning blanks) provide superior line and leader control when trying to achieve drag-free drifts. They also allow for big fish playing capabilities on light tippets due to their soft actions and shock absorbing abilities.
A floating fly line, like the Wulff Triangle Taper, works well on the spawning beds particularly when fly casting at a relatively short distance (30 ft. or less). They have the delicacy of a double taper at short distances, which makes line mending rather easy, and at the same time provide the power of a weight forward to turn over split shot and floating indicators. This is due to their unique triangle taper configuration, which concentrates the bulk of the heavy part of the taper (which can interfere with drag-free drifts) away from the butt of the leader.
Leaders should be kept relatively short (9-10 feet) when fishing the beds. This allows for close in casting in relatively shallow water. In adjacent runs and pools (which are deeper) longer leaders up to 12 to 14 feet work better especially when using a floating indicator. Adding a florescent red section of Sunset Amnesia monofilament to the butt section of the leader is a good way to build a strike indicator into your leader especially when you are not using a float.
Fly fishing steelhead spawning beds seems to have its proponents and detractors. In the Pacific Northwest this practice is strongly discouraged on rivers with wild steelhead feeling it is very detrimental to successful spawning. On the other hand Michigan steelheaders seem to have no problem with fishing on the beds even though 50 % of their fish are known to be naturally reproduced. The American tributaries of Lake Erie produce a very small number of naturally reproduced steelhead (the runs are primarily based on hatchery raised steelhead smolts and fingerlings) so fishing the beds does not have much of an impact on future steelhead runs. One exception is the Cattaraugus River in New York which has been documented with 25% naturally reproduced steelhead. Here it is not recommended to fish the beds in the spring to protect a developing wild steelhead fishery.
