During our May meeting we had a discussion concerning stillwater trout fishing, and stillwater fishing opportunities in our area.

video producer, lecturer, and angling guide.
Trout in stillwaters often have a capacity for quick growth and large size, because they don’t have to constantly fight current, and their food supply is more stable through the year.
Thousands upon thousands of
lakes—from tiny alpine tarns to large, lowland irrigation impoundments—dot the
geography of the Western United States and Canada. Many of these water bodies
are incredibly rich ecosystems that support self-sustaining or augmented trout
and char populations.
These waters support diverse fishing
opportunities, from lots of small fish to quality, managed fisheries that
regularly produce fish in excess of 10 pounds.
Each year more and more anglers are
discovering the challenges and rewards of fly fishing in stillwaters. While
there is a mind-shift in thinking standing versus moving water, the basic
fishing instinct and level of angling success in either venue is gauged by our
understanding of where the trout live and how they interact with their primary
food sources. An added bonus is that many of the most significant trout foods
are aquatic insects that are common to both stream and stillwater environments.
Trout have simple lifestyles once we
look beyond the basics of adequate water quality. They need access to
productive feeding zones, as well as nearby resting areas where they are safe
from predators.
In lakes, the most abundant sources
live in the shallow water or shoal zones of the lake. This equates to water
less than about 25 feet in depth.
Within this depth range, sunlight
energy can penetrate to the lake bottom and allow photosynthesis to work its
magic. Submergent and emergent green plant growth thrives under the influence
of a long, sunny growing season. Underwater forests of pondweed, coontail,
milfoil, bulrush, cattail, and chara provide ideal habitat for important
invertebrate trout food sources. They include scuds, midges or chironomids,
mayflies, damselflies, dragonflies, caddisflies, leeches, water boatmen, and
backswimmers.
The transition zone between the
shoal and deep water is known as the drop-off. Plant life becomes less abundant
as the water gets deeper because the influence of photosynthesis becomes less
pronounced. Drop-offs are important refuge areas for trout, particularly during
warm summer periods when the shoal water can be too warm for the trout during
daylight hours.
The deepwater zone of the lake is
often referred to as the abyss, as it is the deepest part of the lake. The
maximum depth of many small trout lakes is often less than 50 feet, but they
can be much deeper. The deep water is home to tiny crustaceans such as
zooplankton, which at times are an important part of the diet of all age
classes of trout and in particular of juvenile fish.
At other times of the year, the
deepwater zone yields significant chironomid emergences, bugs coming off in 65
feet of water and trout gorging on the pupae right at the lake bottom. That
scenario does provide some very interesting fishing opportunities.
In the fall, water boatmen and
backswimmers undertake mating and swarming flights, which often sees them
diving into the deep water of the lake. Trout sense their presence and take
advantage of this abundant food source in water that is less traveled.
The most prolific and well-known
North American stillwater fisheries are blessed with the right combination of
water chemistry, a good balance of shoal and deeper water areas, a diverse food
base, and a long growing season. Add some progressive fisheries management
objectives and regulations, and you create another fly-fishing paradise.
The most common chironomid colors
are black, brown, green, and maroon. Ascending pupae often take on a silvery or
silvery-gray sheen due to the gases that build up under the shuck before they
emerge.
Fishing from a Boat
All the fishing tactics discussed in
this article are based on presentations from an anchored craft. If possible,
your boat should be anchored from both the bow and stern so that changing wind
directions will not move the fishing platform. This setup allows you to
maintain control over retrieves, which is critical to detecting strikes
regardless of line type or retrieve.
A depth sounder/fish finder is
another key piece of equipment. They allow you to see the shoals, sunken
islands, drop-offs, old stream or river channels and they tell you the depth
you are fishing.
Sounders with side-scan capabilities
are ideal since so much of the best fishing occurs in shallow water. Having the
ability to scan fish to the side or in front of the boat confirms that you are
fishing over productive water. The bottom line is that proper depth
presentation and fishing location are as important as having the right fly.
The most prolonged and abundant
aquatic insect emergences in Western stillwaters are chironomids or midges.
They are always the first hatch of the year, and often also the last hatch of
the year just prior to winter and ice cover. There literally could be several
hundred species of chironomids inhabiting any given trout lake. Trout of all
sizes will feed on the larval, pupal, and adult stages of the chironomid, but
it is the pupa that fish literally gorge on day after day for weeks on end
during the spring through mid-summer period and then intermittently right up until winter sets in.
Big trout love to eat small food
items when they are in abundance.
Callibaetis nymphs live in a lake’s
weed beds. Use short, 2- to 4-inch pulls to imitate the swimming action of
these nymphs. “Small” is a relative term when it
comes to describing the size range of chironomids found in productive Western
stillwaters. Pupal patterns are tied in hook sizes ranging from almost minute
#20 to big bombers on #10-3XL. A heavy chironomid emergence could easily see
literally hundreds of thousands of the pupae in one small area of a lake making
their way to the surface to complete the transformation to the adult phase.
Trout simply swim through the water inhaling pupa after pupa with each breath
they take.

One of the most effective methods to
fish the chironomid pupa is with a floating line and strike indicator. While to
some this form of fishing is similar to watching paint dry, it is a deadly way
to present and maintain chironomid pupal patterns at precise depths.
The majority of chironomid emergences occur in depths of less than 20 feet, which provides the perfect situation to fish with indicators. The general rule of thumb when fishing chironomid pupae is to fish them as close to the bottom of the lake as possible, which means setting the indicator so that the fly is suspended between 12 and 16 inches off the bottom.
In most emergence situations the
trout prefer to feed on the pupae closer to the bottom than higher in the
water. This is particularly true in clear lakes, where feeding higher in the
water increases their exposure to predators such as ospreys and loons. In many
jurisdictions it is legal to fish with more than one fly and suspending two
different colored pupal patterns spaced about 18 inches apart can really help
narrow down specific color preferences for that particular emergence.
It is critical to watch the strike
indicator closely. There are days when the strikes are aggressive and the
strike indicator goes down hard, but other times it barely moves or quivers,
and a slow response will miss the fish completely.
Pupal color choice should always be
based on examining the real pupa or newly emerged adults or by using a throat
pump to sample the live pupa in the throat of the fish. Matching pupal size and
color as closely as possible is often the difference between a great day on the
water compared to just the occasional hookup.
Hatching Callibaetis duns provide
the best dry-fly fishing of the year on many Western stillwaters. A Parachute
Adams is an excellent imitation of this important mayfly species.
Chironomid pupae can also be fished
with floating lines without strike indicators. In this method use a leader at
least 25 percent longer than the depth of water being fished. For instance, if
anchored in 12 feet of water I use a leader that is 15 to 16 feet in length,
and I allow plenty of time for the fly to sink.
Determine where the fly is in
relation to the lake bottom by using your watch to record the seconds, and when
you think the fly is close to the bottom, begin a slow hand-twist retrieve.
This moves the pupal pattern horizontally through the water while staying in a
very narrow depth zone close to the lake bottom. If the fly hangs up on the
bottom, reduce your wait time on the next cast.
This same setup can be used to wind
drift pupal patterns. Try this method when there is a slight breeze on the
water. Make a cast perpendicular or 90 degrees to the wind, and allow a belly
to form in the line as it slowly drifts downwind. The pupa will be drifting
naturally just off the lake bottom. Watch the end of the fly line for strikes,
which will vary from aggressive, hard pulls to slight hesitations in the drift.
Chironomids also emerge from deep
water, often in excess of 50 feet, particularly later in the season. Use
full-sinking lines to imitate the natural pupal ascent from these depths.
I use a type 6 or 7 sinking line
with a 6- to 7-foot leader, and cast the same length of line as the depth of
the water. If I’m anchored on 50 feet of water, I cast about 50 feet of fly
line. Wait for the line to sink until it is straight up and down, and then
start a slow hand-twist retrieve to pass the pupal pattern through all the
potential feeding zones.
Typically, the fish take the fly
within a few feet of the bottom or follow it up to within 10 feet of the
surface before striking. It can be exciting fishing, as the takes are not
subtle.
More recently, anglers have been
fishing chironomids in even deeper water, as much as 80 feet in depth. It has
been effective to just suspend the pupal pattern a couple feet off the lake
bottom and wait for the rod to double over. Make sure you are holding the rod
securely when fishing this technique.
Regardless of the tactic or fly line
type, make sure your fly is tied on with a nonslip loop knot. This simple knot
significantly increases the number of fish you hook simply because the fly
moves so much more naturally. As a general rule of thumb, use loop knots when
fishing any fly under an indicator and natural movement is important.
The most common chironomid pupal
colors include black, brown, green, maroon, and various shades of these colors.
Ascending pupae often take on a silvery or silvery-gray sheen, a result of
gases that build up under the pupal shuck in preparation for the adult
emergence.
The two most important and most
common pupal colors are a black-bodied pupa with a red wire or red holographic
tinsel ribbing, and a gunmetal gray Flashabou pupa with red wire or holographic
tinsel rib. The key is matching the real bugs as closely as possible in terms
of size, shape, and color.
Prolific chironomid fisheries in
British Columbia include Dragon Lake near the city of Quesnel and White lake
near the city of Salmon Arm. Both fish well during May through mid-June. There
is also a good chance to hit respective Callibaetis mayfly emergences at both
these lakes during the same time period. Crane Prairie Lake near Bend, Oregon
offers heavy emergences of a variety of sizes (species) of chironomid pupae
through June and July. The fishing gets better as hot summer temperatures settle
into the area.
Many Western stillwaters support
healthy populations of mayflies. The most widespread are those found in the
genus Callibaetis, the speckled-
winged mayflies. The preferred habitat of mayfly nymphs is the lush emergent and submergent vegetation growing within the shoal or littoral zones of the lake. There, trout feed on the immature nymphs, migrating mature nymphs, emerging adults, newly emerged duns and egg-laying spinners.

Olive/brown damselfly nymphs swim
toward shore when they are about to emerge and crawl out on shoreline
vegetation. Subsurface fishing with them is best when the nymphs are migrating,
and the trout prey on them around the weed beds.
Depending on the size of the lake
and elevation, you may encounter mayfly hatches right from mid-spring through
summer. Often, the emergence is most intense over a one- to two-week period.
In the majority of productive lakes,
the nymphal swim to the surface of the lake attracts the most intense interest
of foraging fish. These fully developed nymphs are easily recognized by their
swollen and darkened wingpads. They swim on a shallow angle to the surface,
where the dun or nonreproductive adult emerges.
Floating lines with 12- to
20-foot-long tapered leaders and nymphal patterns are my go-to method of
presentation. I prefer to make long downwind or wind drifted casts, and allow
the fly to sink close to the bottom. Use slow, 2- to 4-inch-long strips
interspersed with several short, quick pulls.
Bulging or porpoising riseforms are
telltale signs that the fish have switched from feeding on subsurface nymphs to
the emerging adults. Look for individual feeding fish, track their movements,
and place a cast well ahead of the fish using an emerger pattern on a floating
line and a 12- to 14-foot leader.
This emergence also offers some
great dry-fly fishing as newly emerged duns and returning egg-laying spinners
are extremely vulnerable when they pause at the surface. Swirling and splashy
riseforms are good indicators that some surface feeding is underway. Again, it
is important to be constantly watching the lake for insect presence, fish
movement, and the presence of birds that are likely also feasting on the same
bugs.

stillwaters. Pheasant-tail Nymphs, Gold Bead Flashback Pheasant-tail Nymphs,
Bird’s Nest Nymphs, Parawulff Adams, and Parachute Adams in sizes 12 to 16
should be in your fly box.
Sheridan Lake in the Cariboo region
of B.C. sees an intense but relatively short emergence of Callibaetis during
June and early July. Chopaka Lake in eastern Washington has good emergences
during the month of May, and Hebgen lake in Montana offers consistent mayfly
fishing opportunities through July and August.
Damselflies
Damselflies are another common inhabitant of productive Western stillwaters. Like mayflies, the damselfly nymphs frequent the vegetation growing in the shallow areas of a lake. The damselfly nymph is a carnivore, often preying on immature mayfly nymphs, scuds, and anything smaller than itself.

The nymphs can take up to four years
before emerging into the adult stage. Trout seek out both immature and fully
developed nymphs. Some of the most intense feeding occurs when the mature
nymphs leave the protection of the dense aquatic vegetation to complete their
life cycle. This emergence swim sees the nymphs swim near the surface in search
of stalks of longstem bulrush or cattails to crawl up and out of the water.
Once out of the water, the adult
form emerges from the old nymphal shuck. The migrating nymphs swim in a slow,
sinusoidal motion within a few feet of the surface of the lake, making them
easy targets for hungry trout. Observant anglers often see the nymphs swimming
in the water.
The ideal way to fish this emergence migration is with a floating line setup with a 12- to 14-foot leader and a damselfly nymph pattern that closely matches the olive/brown color of the real insects. Situate your boat so that you are casting out into the lake and retrieve your fly in the same direction that the real nymphs are heading—most often this is toward shore.

Situate your boat so that you are casting out into the lake and retrieve your fly in the same direction that the real nymphs are heading—most often this is toward shore.
A common strategy for me is to
anchor my boat right along the edge, or partially within a heavy patch of
bulrush. I cast out into the lake, allow the fly to sink 3 to 4 feet down, and
then start a slow retrieve of 3- to 5-inch pulls toward the boat. Remember, the
real nymphs take regular pauses during this swimming adventure.
In the fall, trout search out the
juvenile nymphs that are hiding in the submerged vegetation. A great way to
fish with baby damselfly nymphs is to suspend them under a strike indicator,
and fish the edges of weed patches or the open holes within the dense plant
growth. Work the fly just off the lake bottom, and give it occasional quick
irregular pulls just to add a bit of erratic movement. More often than not, the
trout will eat the nymph as it just hangs there.
Newly emerged and fully developed
adult damselflies are also highly
prized food items. Trout move into the shallow-water stands of cattails and bulrushes and sometimes crash their bodies against the plant stems to knock the still fragile adults into the water, where they become helpless floating meals.
prized food items. Trout move into the shallow-water stands of cattails and bulrushes and sometimes crash their bodies against the plant stems to knock the still fragile adults into the water, where they become helpless floating meals.
Windy days and downdrafts also knock
hovering adult damselflies into the surface film. Make sure you have a few
adult patterns in your box for those special days of frenzied surface feeding
activity.
Well-known damselfly nymph patterns
include Whitlock’s Damsel Nymph and Kaufmann’s Marabou Damsel.
Henry’s Lake in eastern Idaho is
well known for its prolific population of damselflies that result in heavy and
prolonged emergences through the months of June and July.
No stillwater fly box is complete
without a good selection of leech patterns, and although they do not emerge or
hatch like an aquatic insect, they are an important food source during all open
water periods.
In the fall especially, leeches become a significant source of protein as fish are bulking up prior to winter ice cover.
In the fall especially, leeches become a significant source of protein as fish are bulking up prior to winter ice cover.
Leeches are reclusive, typically
found hiding under rocks, within woody debris, and in vegetation that covers
the benthic areas of the shallow shoal zones of the lake. They are active in
low-light conditions and at night, which helps explain why night fishing in shallow
water during warm summer months can be so productive.
Leeches come in various colors
including black, shades of brown, green, maroon, and mottled variations of all
these colors.
They are long-lived, and can reach lengths in excess of 8 inches when fully extended. Leeches swim in a distinctive up-and-down undulating motion that fish find hard to resist.
They are long-lived, and can reach lengths in excess of 8 inches when fully extended. Leeches swim in a distinctive up-and-down undulating motion that fish find hard to resist.
While there are lots of big leeches
available, it is often the very small leeches that find their way into the
stomachs of the trout. That is why micro leeches have become so popular. By
small we are talking about patterns tied on #12 or #14 scud hooks.
Leeches can be fished with floating
or with sinking lines of various densities. However, much of my leech fishing
occurs along the edges of drop-offs into water less than 5 feet deep. This
makes floating lines an ideal choice, with tactics similar to those described
(above) for chironomid pupae.
Leeches are particularly effective
when fished under an indicator. My favorite presentation is to cast into a slight
breeze, and allowing the fly to drift back in a natural, drag-free drift. The
combination of the up-and-down motion of the indicator, with a loop-knotted
tungsten beadhead leech, makes this an ideal way to cover prime real estate of
the shoal zone.
Clear intermediate sinking lines are
another proven way to fish leeches in water less than about 18 feet deep. The
slower sink rate of this line can be used in combination with slow strip or
hand-twist retrieves to keep a leech pattern moving along just above the bottom
substrate.
The edges of the drop-off can be
fished with faster-sinking lines that are matched to the slope being fished. I
anchor just on the edge of the drop-off, and cast out over deeper water for a
retrieve that climbs up the face of the slope, but you can also anchor on the
drop-off slope, and cast parallel to it. Both methods are covering prime
fish-holding water.
There are many fish-catching leech
patterns to choose from. Many are tied with dubbed mohair-based materials
and/or with marabou, as both breathe and pulse when stripped or drifted through
the water.
Beadhead patterns add more flash and further irregular movement to the fly especially when tied on with a loop knot. The Ruby-eyed Leech, maroon micro-leech, and rabbit strip leech are tying styles that are consistent producers in lakes throughout the West.

These are just a few of my favorite
and most dependable methods to fish productive Western stillwaters. Use them as
a starting point, and as you find success, I’m sure you’ll add variations to
suit your local ponds, lakes, and reservoirs, and make your outings more
enjoyable.

Lake Turnover
With the advent of spring, the warming/melting of the ice layer at the surface and the much smaller temperature differences in the water column, winds and storms are able to create a spring turnover with little difficulty. As the waters continue to warm, stratification begins again and the endless cycle continues. Mother Nature has performed her timeless and never-ending task, adding additional life-giving oxygen to the lake and readying it for the onslaught of another season of fishermen.
