Fly Fishing Letort Spring Run
The Letort Spring Run is a beautiful little limestone
spring creek located right in the town of Carlisle
Pennsylvania. In the upper section of the stream, it
is so clear that you can look at it in some ways as
not even being a stream because of the beds of
cress. In places it looks to be only a few inches
deep until you step into the water and find out it is
two feet deep. It probably only averages about
twenty feet wide. Some very large springs keep the
water flowing cool even during the hottest part of
A mile and a half of the little stream is catch and
release water only. The catch and release water
tends to have more larger brown trout than the
other water but it is more difficult to fish. The lower
end of the stream has some runs and riffles areas
and the faster water makes it a little easier to catch
trout. It has some open areas that are easier to cast
in and fish than the middle and upper areas of the
Fly fishing the Letort Spring Run will force you to
become extremely proficient in every thing you do.
A bad cast and you will need to move somewhere
else. Get a bad drift and you will need to cast to
another location. Let the trout see you and you are
finished in that area of the little stream. Hook a
good fish and you have yet another problem. You
usually have very light line and the brown trout has
all the cover it needs to wrap around and break
your tippet. They are very difficult to land in most
The Hertiage Trout Angling regulations (catch and
release with barbless hooks) covers a mile and a
half stretch from three hundred yards above the
bridge at route 481, down to the Reading Railroad
Bridge. The stream flows through Letort Spring Park
just below the Hertiage Trout Angling section. It
enters the Carlisle city limits just below the park.
There is another area of the stream that provides
good fishing upstream from where the Letort enters
Conodoquinet Creek. The lower section of the
Letort provides easier fishing.
Fly fishing Letort Spring Run is quite different from
fly fishing just about any other stream, including
most spring creeks. What makes it even more
difficult than normal is the amount of aquatic
vegetation in the water and the thick trees, bushes
and undergrowth along the banks. It is more like
fishing a jungle than anything I can think of. If they
had trout streams in the Amazon Forest, that would
probably be similar.

There is really no best time to fish the
Letort. It is fairly tough anytime.
Spring is the best time to fish the Letort
because there are more hatches and the
fish seem a little more aggressive during the
Summer can be okay. There are some
sulphur mayflies in the stream and there is a
trico hatch that occurs in late summer in
parts of the stream.
Fly Fishing Guide to Letort Spring
The water forces you to fish very light
leaders and tippets. It also becomes very
evident that the closer the fly you use looks
and acts like the real thing, the better your
chances of fooling a trout. The Letort's
brown trout have most likely seen about
every fly and every angler that comes near
its waters. They are not easy to catch. It is a
very small stream with bushes and trees
surrounding most areas. It is tough to cast in
its tight conditions. The stream has large
beds of cress that in some cases almost
cover the width of the stream. The fish hold
in very difficult places for you to get your fly
to, much less get a good drift. The cress
swirls the currents in a manner that creates
conflicting currents just about everywhere.
When you wade you have to be extra careful
because the water is clear, basically shallow
and the trout are difficult to approach. When
you do get into the right position, you must
make a very accurate presentation.
You only have an area of a few inches to
land you fly in at times in order to get the
drift you need to get. You have to be very
good at fishing very small flies. When
something is hatching and the fish are
rising to it, you must capitalize on it. You
want to take advantage of the hatch
because it is probably the easiest time you
are going to have to catch trout. You can
catch them in deeper water on nymph,
cress bug and scud imitations but it is
usually more difficult than it is fishing a
Cloudy days are always the best days to
fish the Letort. Bright, clear days add
another problem to the already tough
fishing situation. The trout will hide in
heavy cover out of the sun and that makes
it just that much more difficult to catch
them. You are far better off fishing low light
conditions. Early morning, late evenings
and cloudy, rainy days are best.
Letort Spring Run Hatches and Trout
Our information on aquatic insects is based
on our stream samples of larvae and
nymphs, not guess work. We base fly
suggestions on imitating the most plentiful
and most available insects and other foods
at the particular time you are fishing. Unlike
the generic fly shop trout flies, we have
specific imitations of all the insects in the
Letort Spring Run and in all stages of life
that are applicable to fishing. If you want to
fish better, more realistic trout flies, have a
much higher degree of success, give us a
call. We not only will help you with
selections, you will learn why, after trying
Perfect Flies, 92% of the thousands of our
customers will use nothing else.
There are few aquatic insect hatches on the
Letort Spring Run. Most of the food for the
trout consist of scuds and sowbugs. There
are also some sculpin and minnows.
The first hatch that takes place in some
sections of the creek are the Blue-winged
Olives. This occurs about the first of April
and generally last about the entire month.
From all we can gather, this is not a large
There is a minor Sulfur hatch that takes
place in some sections of the stream in May
and June. This is not a huge hatch and
according to many anglers we have talked
to, doesn't even exist anymore. We have
talked to some that disagree and say it still
occurs. I think it may be just a matter of the
location on the stream.
Midges hatch throughout the year and
maybe the most important aquatic insect.
You should have imitations of their larvae,
pupae and of the adult midges.
We think streamers are important flies to
have with you. I would suggest small to
medium size one that imitate sculpin and
The most important flies, according to the
local anglers, are terrestrial imitations. Ants,
grasshoppers and beetles are all present
and eaten by the trout. Some of the
patterns for these flies were developed on
this trout stream. Another local favorite fly is
the Jasid or leaf hopper.
We hope you will try our "Perfect Fly" trout
flies here. We have the best scud and
sowbug imitations you can buy. Our Trico
imitations cover every stage of the hatch
and include flies for the male and females
that are different colors. If you haven't done
so already, please give them a try. You want
Tricos are the most important mayfly hatch
that takes place. It starts in June and last
through the most of September but it
depends largely on the location.
The main food are the sowbugs and scuds.
They are very plentiful. You want to be
certain to have imitations of these.
There can be hatches of BWOs in the fall
that are good.
Warm winter afternoons can be okay on

one good report from a customer using
streamers. It will be back in good shape soon.
07/12/15 No reports from anglers but
conditions are still good. .
07/19/15 Still a little high but sometimes that

08/09/15 Fish terrestrials were they were
made famous - Letort Spring Run.
08/16/15 It is going to be hot again for the next
week but ants, beetles and hoppers will work.
08/23/15 Most non local anglers think of the
Letort Spring Run as a smooth, weedy spring
creek unaware it also has some fast water

using size 14.
09/13/15 Two good reports from local customers

09/27/15 Excellent conditions exist. Don't be
surprised if a 20 inch brown comes up and eats
your Perfect Fly Japanese Beetle. They are
getting colored up for the spawn.
10/11/15 Now is a good time to catch a large
brown trout. They are in the pre-spawn stage
and aggressive. Use the Brown Sculpin.
10/25/15 Customers are reporting catching
some very nice size browns. Good stream
conditions and weather. Great time to fish the
Letort. Terrestrials, ants and beetles are still
working and BWOs are hatching again.
11/01/15 Excellent conditions with Blue-winged
olives hatching and ants and beetles still
working good. Browns near spawning.
11/15/15 The stream has been a high recently
but back down near normal levels. The higher
levels and slight stain actually helps. Hatches
are down to Midges and BWOs, but don't
forget scuds. They always work.
11/29/15 Fish the upper section of the creek
and stay hidden. It is really that simple. The
water temp will remain in good shape and the
brown trout hungry. Sight fishing is the way to
12/13/15 There is unbelievable weather and
stream conditions for December. Little BWO
nymphs, midges and scuds are what you need
to use in addition to the brown sculpin streamer.
12/20/15 The weather is unreal for this time
of the year and you have an excellent chance
of catching trout on the creek. Scuds and
little BWO nymphs would be good choices.
12/27/15 The creek is high but that only helps
Letort Spring Run. The slight stain helps fool
big fish with flies like our Brown Sculpin.
01/10/16 The stream levels are very high and
the water stained. You can still catch trout.
We recommend the White Belly Sculpin.
01/24/16 Stream levels are normal and the
water clear. The weather is looking fairly
good as well. Some big brown trout are
hidden looking for something to eat. It is a
good time to fool one of them.
01/31/16 Great conditions exist on the Letort.
Good levels with some rain through
Wednesday. Small (18's/20's) Blue-winged
Olives could hatch this week.
2/07/16 The stream is flowing high and with a
slight stain but that only makes it easier to
catch trout in the Letort.
02/21/16 We had two good reports of brown
trout being caught this past week. The water is
a little high and stained. The White belly sculpin
is a good fly to use under these conditions.
02/28/16 No reports from anyone fishing this
past week. The levels are up but that shouldn't
adversely affect the fishing.
03/06/16 The creek is in great shape from the
uppermost section to the lowest section. The
water is clear and a little warmer. The are great
conditions for this time of the year.
03/13/16 Great conditions exist. There's a lot
of rain on the way, and this is a good stream to
fish on high water levels.
03/20/16 Stream levels are fine. Blue-winged
olives and midges are hatching. Scuds should
work good at this time of the season.
03/27/16 Big brown trout await you little BWO
dun. Good stream levels and warmer water.
04/10/16 The cold weather is over and the rain
will cease on Tuesday. The stream is a little
stained and that just makes it easier to catch
trout on the Letort. Scuds and little BWOs.
04/24/16 Stream is in good condition with
Blue Quills, BWOs and little black Grannon
05/01/16 Two good reports from customers
using Scuds and Brown sculpin streamers this
past week. Look for higher water this week.
05/08/15 More good reports. Lots of hatches
taking place. Rain has water with some stain
and Sculpin Streamers catching big browns.
05/15/16 Great conditions for the little spring
creek. Good levels and lots of Blue-winged olive
hatches. Sulphurs are hatching good on the
lower end of the stream and soon everywhere. .
05/22/16 The upper end of the stream is
smooth flowing, clear spring water and isn't
exactly easy to fish. You have to stay hidden
from the trout. Some do and catch trout.
06/05/16 If you're having trouble fishing the
upper smooth flows, try the shallow riffles at
the lower end of the creek. It is easier to fish.
06/19/16 The creek is in great shape with
terrestrials becoming important. There are still
hatches but they will drop off during the coming
month. Ants, beetles and hopper will work good
in their absence. They made this creek famous.
07/03/16 Although there are still some
Sulphurs, Cinnamon caddis and other hatches
taking place, terrestrials are important - ants,
07/10/16 The Sulphurs are about done in the
lower river but there are some in the upper.
There are lots of Cinnamon Caddis.
08/07/16 Sorry for the missed reports. The
creek has been in good shape and customers
catching some nice trout. Japanese Beetles,
Carpenter ants and hoppers are working good.
08/14/16 Good conditions exist. Two good
reports from the past week.
08/21/16 The thing this creek was made
famous for is working great - grass hoppers.
Stay hidden and fish then near cover.
09/18/16 It is raining now, but ending today.
Terrestrials still working for those who can
10/02/16 This is an excellent time to fish the
Letort. Brown trout are aggressive and getting
into the pre-spawn stage.
10/23/16 The recent rain helped add some
fresh water. Brown trout are pre-spawn and
some actually spawning.
11/13/16 Sorry for the lack of reports. Fishing
has been very good. Terrestrials are about
done. Blue-winged olives, scuds, Cream
midges, Slate drakes, and damsel and
dragonfly nymphs are working.
11/27/16 The Letort is in good shape. With
most streams running very low, this should be
a prime destination. Midges and BWOs are
12/11/16 The creek is in excellent shape,
especially in the upper sections near the
springs. Don't forget scuds. This creek is full
of them and imitations do catch trout.
12/25/16 This should be a good week to fish
the Letort. Warmer weather has the water
temperature up a little. Midges,, creams and
light greens, are hatching good.
01/08/17 The C&R section is turning out some
good trout for the few fishing it. The water is in
good shape with midges the main insect to
imitate. There are lots of Reds, or blood
midges. Fish the larva and pupa in tandem.
01/29/17 Fish the upper end of the creek near
the springs. The water is warmer and there's
plenty of big brown trout. Fish midges, little
BWO nymphs, or scuds.
02/05/17 A good destination at this time of the
year. Fish the upper sections. You have to
stay hidden from the trout.
02/12/17 One good report from a customer
sight casting little BWO nymphs. Stay low and
hidden and fish the upper section of the creek.
02/19/17 Excellent conditions exist. Fish
Sculpin streamers when cloudy or raining.
Fish Midges, Creams or Red, otherwise.
02/26/17 Excellent conditions continue to
exist. Fish any section of the stream. Use
sculpin streamers during low light conditions.
03/19/17 Fish the upper part near the springs
the next day or two. The middle and lower
sections should be in good shape by mid week.
03/26/17 Little Black caddis should start
showing up anytime now. Blue-winged olives,
size 18-20, are hatching now.
94/09/17 Lots of hatches and great
conditions for this coming week. Fish the
upper or lower sections.
04/16/17 Two good reports from the past
week. Lots of Blue-winged olives, Blue-quills,
little Black caddis and other hatches.
04/23/17 Good reports coming in for the Letort.

04/30/17 Two good reports came in from
Yesterday. Lots of caddisflies and litle BWOs
05/07/17 The stream level is high in the middle
and lower sections of the creek, but okay to
fish in the upper spring creek section.
05/14/17 It is still a little high but falling down
to normal in another day or two. We received
a good report from the upper part last week.
