Mike and I had planned to swing flies for steelhead on the Deschutes last weekend, but time got the better of us. Instead, we opted for cooler weather and a partly cloudy day exploring one of the Cascade Lakes for stillwater brook trout. Brookies are known for their stunning coloration and aggressive takes, and these ones were no exception. Here’s how we approached the day and found success fishing damselfly nymphs.

The Lake in Question
This lake sits at about 5,000 feet above sea level and has an interesting history. Until the mid-50s it was a bog full of carp, later treated and restocked to support an Atlantic salmon sport fishery. When the salmon failed to thrive, the program was abandoned in favor of planting big redbands and brook trout. The lake now offers numerous chances at a robust brook trout population, cutthroat, and rainbows up to several pounds.
Today, the lake is among the richest in Central Oregon. Its clear, shallow water averages 3–4 feet deep and is lined with bullrushes and water lilies. Sight-casting opportunities abound, and despite the daily “paddleboard hatch,” the trout here are willing to eat a well-presented fly. Thanks to the abundance of aquatic vegetation, damselfly nymphs are often the most reliable option.

What is a Damselfly?
Damselflies are essentially smaller, slimmer cousins of dragonflies. Here in Central Oregon, the adults are bright blue and thrive in plant-rich waters. For fly fishing, we usually focus on the nymph stage. Adults are bulky and awkward to cast, while nymphs are abundant and trout key in on them heavily.
Damselfly nymphs are slender, usually olive, and poor swimmers. They spend two years feeding underwater and molt about a dozen times before migrating to shore, climbing up the bullrushes, and emerging as adults. Because they’re such weak swimmers and so plentiful, trout hunt them aggressively. Any stillwater with healthy weed beds and shoreline vegetation will support a strong damsel population.

Fishing the Damselfly Nymph
Fishing damsels is one of my favorite ways to approach lakes—it’s active, visual, and effective. The best window is usually mid-morning through early afternoon, when the nymphs migrate from the lake bottom toward the shoreline vegetation.
Rigging is straightforward. A floating fly line paired with a long leader on a 5- or 6-weight rod is all you need. I like the Scientific Anglers Anadro floating line because it handles indicator rigs, balanced leeches, woolly buggers, and lightly weighted damsel patterns without fuss. Whatever line you prefer, run a 12-foot leader tapered to 3X tippet. The heavier tippet helps turn over weighted flies and withstand aggressive strip-sets. You can also run a hover or intermediate line (1-2 in sink/second) with a shorter leader, but it isn’t entirely necessary in a shallow lake like this. I don’t own one of these lines but might end up with one by next summer. I’ll be sure to write a review when it happens.
For presentation, I fish a single fly tied on with a non-slip loop knot to maximize movement. Cast along the edge of the bullrushes or slightly beyond into open lanes near vegetation. Let the fly sink a few seconds, then retrieve slowly. My go-to is a figure-eight hand-twist retrieve with occasional pauses, though long, slow strips also work. The key is keeping it subtle—mimicking a clumsy, slow-moving insect. When a brookie eats, strip-set firmly.
The Flies Themselves
At its core, a damsel nymph is just a slim olive woolly bugger in size 12–14. If you don’t have damsel-specific patterns, a small bugger will do fine. Tan, brown, or mottled olive variations can be equally effective.
My favorite pattern features an olive marabou tail, olive marabou body, chartreuse wire ribbing, a wood duck wing case, and a partridge collar. (Check out John Kreft’s recipe for a step-by-step tie.) A small bead helps with sink rate—enough to hover in the water column without giving it a jigging action. Some tyers opt for a tiny set of dumbbell eyes for realism and light weight. I think it might be overkill, but it definitely doesn’t hurt. Just keep the fly light and alive; too much weight kills the presentation.

A Day on the Lake
Stillwater fishing is one of the best ways to break up summer. There’s something about loading the canoe or float tube, packing a cooler of Rainiers, and settling into the slower rhythm of lake fishing.
Lakes like this one in the Cascades are a sight to behold. Towering ancient volcanoes, clear waters with plenty of sight fishing opportunities, and an overwhelming variety of bug life paint an incredibly vivid picture of what a healthy ecosystem looks like. Whether I’m on the river or a high lake, I’m always reminded of the same truth—trout live in beautiful places.
