As predicted in the last report, we hit a little bump in the road last week. A significant cold front hit on Wednesday and dropped water temperatures in a big way. We are gradually recovering from that and things improved a lot this weekend. Rain on Saturday helped. Not only did it warm water temps a little, streams were starting to get a little low for this time of year.
Projected Conditions
We’re going to make a hard rebound this week with temperatures reaching the 80’s mid week. It’s hard to believe that the projected high for this Wednesday is about 40-degrees warmer than last Wednesday! These poor trout don’t know if they’re coming or going. Otherwise, mostly a dry week with better chances for rain late week. It’s going to be hard for me to not wet wade Wednesday and Thursday but I’m going to give it another week or two.
Tips
I’m expecting fish to really turn on this week and stay a little more consistent. As it warms up, fishing should be pretty good at all elevations. If you’re heading to the high country I’d focus more on the afternoon. Trees are beginning to fill in which will help, too. Some of those warm days two weeks ago were tough with all of that sun hitting the water.
Hatches/Fly Suggestions
Dry fly fishing should really start getting more consistent this week. We’re starting to transition to “yellow season,” meaning much of what you’ll see hatching will be yellow. Blue Quills (#18) and Light Hendricksons (#14) will likely still be seen here and there. You’ll probably see a fair number of Red Quills (#14-12) and March Browns (#14-10) as well.
But look for bigger numbers of sulphurs (#16), Light Cahills (#14-12) and Yellow Sallies (#16) over the next 4 or 5 weeks. Caddis are also abundant this time of year depending where you are. A tan body in a #14 will do the trick.
As always, a good selection of attractors will get you through most situations. Parachute Adams, Parachute Hares Ears, Thunderheads, Adams Wulffs and Royal Wulffs always do pretty well. But as mentioned above, you’ll want to be sure to have some dry flies in yellow. A Neversink in #16 – 14 is a staple for me. So is a Yellow Stimulator. I’d also have a selection of Parachute Sulphurs and Cahills.
For nymphs, try Hares Ears, Pheasant Tails, Copper Johns and Tellico Nymphs. And with so much stuff hatching, now is a pretty good time to start experimenting with soft hackles. Check out my Hatch Guide for complete hatch information.
For the featured fly, I’m keeping the same fly as last week because it should be even better this week! Neversink Caddis. The yellow body version, which is great, is pictured but I’d play with other colors, too. The tan body has been working great lately. It fished well by itself but is also a nice, buoyant fly to support a dropper nymph. Two Fly Rigs.
Fishing is good in the Smokies right now. Water temps are sitting pretty and so are levels. And most important, at least for my sanity, is the crowds have dropped to “reasonable” levels. We’re in a very mild weather pattern and it looks like it may stay this way for a little while. Overnights and mornings are cool with nice warm-ups in the afternoon. Expect your better fishing to be from late morning to late afternoon.
Projected Conditions
Though overall we’re in good shape, it looks like we’ll see a minor setback this week. Rain is expected Wednesday and with it is a pretty significant cold front. Highs on Wednesday aren’t expected to get out of the 40’s and Wednesday and Thursday night lows will hit near freezing. While I don’t think this will have long term effects on fishing, I’d expect pretty slow activity on Thursday and Friday.
Tips
Fish are beginning to spread in the stream more and activity is picking up in riffles and pockets. However, without full tree bloom, fish may be spooky in the bright sunlight. Seek out locations near shade lines. Fishing is starting to get productive even in the mornings in the lower elevations. For mid and high elevation streams, I’d try to focus on the afternoon.
Hatches/Fly Suggestions
Fish are really beginning to look up now and most fish on my trips this past week were taking dry flies. Hatches are fairly diverse right now with very few heavy hatches of one insect coming off. Blue Quills (#18) and Light Hendricksons (#14) are accounting for most of the mayfly activity. Red Quills (#14-12) should begin showing up in better numbers and you may even see a few March Browns (#14-10) showing up early to the party.
There are a lot of small dark stoneflies but the adults don’t spend much time in front of the trout. A #18 Pheasant Tail is a respectable imitation for the nymph. A lot of #16 dun caddis are out and about and starting to see some larger tan caddis in a #14. And I’m seeing a few Yellow Sally Stoneflies. Expect more of them toward the end of the month.
You can certainly carry exact imitations of any of the flies mentioned above. But with so many different bugs and no large numbers of any, keeping your fly pattern fairly generic is not a bad idea. A Parachute Adams and Parachute Hares Ear are really good all-purpose spring dry flies. Thunderheads, Adams Wulffs and Royal Wulffs also do pretty well. On many of the backcountry streams, caddis have been the ticket. An Elk Wing or Neversink in #16 – 14.
For nymphs, try Hares Ears, Pheasant Tails, Copper Johns and Tellico Nymphs.
My most consistent producer has been a creation of my own that I call
an Early Spring Nymph. I’ll include the pattern in my next newsletter.
Until then, an olive Hares Ear is pretty similar. Check out my Hatch Guide for complete hatch information.
For the featured fly, I have the Neversink Caddis. The yellow body version, which is great, is pictured but I’d play with other colors, too. The tan body has been working great lately. It fished well by itself but is also a nice, buoyant fly to support a dropper nymph. Two Fly Rigs.
We’ve gotten a nice, long break from the heavy rains and sharp cold fronts and conditions are actually begining to stabilize. What has not been going our way is an unprecedented number of tourists… and when you’re talking about what is already the most visited national park in the country, that says a lot! It seems to be the perfect storm of spring breakers and Covid shut-in refugees and I’m hoping it slows soon. Right now our national park is being loved to death. With so many people out and about, it may be a good time to brush up on your Stream Etiquette.
But if you can manage to find a quiet place away from the masses, fishing is getting pretty good. Mornings are still a little chilly and it still needs to warm up in the high country. But most everything is fishing well with low elevations and afternoons being the real highlight right now.
Projected Conditions
We have a slight cold front and a little bit of rain in the forecast toward the end of the week but all and all, it looks like a good week ahead. I don’t expect drastic changes in water temperatures or levels. As we get a little farther into April, hopefully spring breaks will wind down and a little of the tourist traffic will decrease.

We are currently in what I would call a recovery stage. It may not be great but it’s definitely heading in the right direction. Water levels have been slowly dropping from last week’s big rains but streams are still a little on the high side. Water temperatures took a big dive too from a significant cold front, but they are slowly climbing back into the 50’s.
Projected Conditions
The week ahead is looking really good. By mid week, temperatures and levels should be pretty close to normal for this time of year. More rain is in the forecast near the weekend but right now, it doesn’t look like the significant systems we’ve seen in the last couple of weeks. Hopefully it won’t play too much havoc on water levels. As always, keep an eye on those stream gauges – reading stream gauges.
Tips
We’re easing back into “typical” early spring conditions. You want to seek out slower water and you want to fish the warmest water possible right now. Try to concentrate your efforts on the middle of the day, stick to the lower elevations and look for areas that get a little more sunlight. Finding Feeding Trout in Early Spring.
Hatches/Fly Suggestions
I had to cancel most trips last week due to high water so I haven’t really had a chance to see if we have any new hatches starting up. I’ll learn a lot more in the coming days. For that reason, I’m keeping the hatch info below the same as last week. However, based on experience and pure speculation, we’re getting to the time when Quill Gordons may be winding down and you may see more Blue Quills and Light Hendricksons. Carry Parachute Adams in sizes 18-14 and you should be in pretty good shape.
Quill Gordons are still popping off here and there. Again, it just depends where you are. I’ve been on pools where I only see two or three, and two pools up they’re coming off everywhere you look. They could show up at any time but mostly, we’re seeing the better hatches mid to late afternoon.
Standard Quill Gordon patterns should work well for topwater, so will a Parachute Adams – sizes #14 – #12. Everyone seems to have their favorite Quill Gordon nymph imitation. Mine is an olive Hares Ear. When the hatch is coming off pretty good, I always do best with an emerger, and my favorite is a Mr. Rapidan Emerger.
Blue Quills are coming off in better numbers in sizes #18 – #16. You’ll probably still run into some Blue Wing Olives, and there is always an assortment of dark caddis and stoneflies this time of year. A size #16 grey Elk Caddis will do the job for most of them. Otherwise, a lot of your favorite attractors should do fine. For early spring, I always like flies with peacock herl, Zug Bugs and Prince Nymphs in particular.
For the featured fly, I’m going to suggest the Red Fox Squirrel nymph for no other reason than it always seems to be a good early spring pattern for me. Clicking the link will give you a lot more info on this fly.
Well, we appear to be in a pattern… and not a very good one I’m afraid. As predicted in last week’s report, just as everything was getting back to normal, we got whopped by a major rain event on Thursday. That was followed by a cold front and another two day bout with heavy rain and storms over the weekend. The result is falling water temperatures and blown out streams.
Actual rainfall totals vary around the region. Middle Tennessee received approximately 7″ in a couple of days. Most of the areas around the mountains received 3-5″. Most streams came up 3-4′ and are still flowing 2-4′ above normal but falling. Not only are these conditions not very productive for most folks, they are just not safe.
In the summertime, water like this usually drops back down to normal in just a couple of days. But in the spring, when we usually get a lot more frequent, sustained rainfall, banks are already heavily saturated and there’s just nowhere for the water to go. So, stream levels tend to drop at a much slower rate. In short, I’d try to find something else to do for at least the next few days.
Projected Conditions
If we didn’t get any more rain, it would likely take about 4 or 5 days for streams to get back down to a “fishable” level – probably a full week to get down to normal. That puts us on track to see reasonable water by Thursday or Friday this week. The problem is we are expecting another 1 1/2″ of rain from late Tuesday night through Wednesday evening, which would easily spike those already high water levels back up 1 or 2′.
To add salt to the wound, Wednesday’s rain will be followed by a significant cold front. Thursday’s high temperature is only going to be in the 40’s. No matter how you slice it, the week ahead doesn’t look too promising. If you’re planning a trip, definitely keep an eye on those stream gauges – reading stream gauges.

This week’s featured fly reflects the water conditions more than it does the seasonal hatches. If you can get on the water at all, it will be high and you’re going to want to fish larger, heavier flies that can get down quickly. Here are a few tips for fishing high water.
Last week turned out to be great until Thursday, which is exactly what we expected. Heavy rain hit Wednesday night and Thursday and brought stream levels up substantially. Additionally we had some cooler overnights over the weekend and water temperatures took a little dip.
We are just now beginning to rebound from those two events. Water levels are still a little high but manageable, especially on smaller streams. And water didn’t come up as much on the North Carolina side, so they are running only slightly above normal.
The best fishing is on lower elevation streams right now. Fish will
be most active in the afternoon when it’s a little warmer. Many anglers
are talking about catching a lot of very small rainbows. This is pretty
common for right now as the larger rainbows are spawning. We’ll
hopefully see them get a little more active in the coming weeks.
Projected Conditions
This is looking like a potential replay of last week. Just as things are bouncing back to normal, we have what may be a big rainmaker system moving through on Thursday. Projections are for more than an inch of rain, which would most certainly blow streams out. And you guessed it, that’s followed by a cold front this weekend. Keep an eye on those stream gauges if you go – reading stream gauges.

Things are starting to get pretty good around here. Water temperatures are remaining in the low 50’s in the lower elevations. We’re beginning to see more consistent feeding activity and hatches are picking up, too. In general, water levels and temperatures are a little better on the Tennessee side of the park right now.

Quill Gordons are beginning to show up in pretty good numbers… some places. This is kind of luck of the draw.

This can be one of the most maddening scenarios when you’re just so ready to fish! We’ve had some beautiful, dry weather the last several days with fairly mild temperatures. It just looks like the fishing would be great! The problem is that our overnight lows are still near freezing so water temperatures are still well below optimum feeding conditions. This doesn’t mean you can’t catch fish but you’re going to have to work at it. Strikes will likely not come frequently and will be subtle. Water levels are slightly above average but very fishable.
Projected Conditions
Here’s the good news. Looking at the forecast, those overnight lows are getting warmer every day. By Wednesday and Thursday they will be in the 50’s. THAT is when your water temperature will start warming up! I think fishing should start getting pretty good on Thursday and hopefully continue for at least a few days.
Rain moves in on Friday but should only cool down a bit. As long as we don’t get huge amounts, we should be in pretty good shape on through the weekend. Just remember, streams are pretty full now and the ground is still very saturated. It won’t take much to spike those water levels. Keep an eye on the gauges – reading stream gauges.
Tips
In general, you want to seek out slower water and you want to fish
the warmest water possible right now. Try to concentrate your efforts on
the middle of the day, stick to the lower elevations and look for
areas that get a little more sunlight. Fishing high water
can be tough and it can be dangerous. Keep an eye on those water
levels. It’s not an exact science but typically, I consider around 2.5′
on the gauge to be the high side of good. Ideally, you want it more
around 2′. Between 2.5′ and 3′ might give you a little bit of manageable
water in very select locations, but you better know what you’re doing.
Above 3′ will leave you very little fishable water and is really just
unsafe.
Hatches/Fly Suggestions
We are still early in the year and most of what you’ll see hatching is dark and small. You may run into the occasional Blue Wing Olive. Small dark stoneflies and caddis may also make an appearance. I would primarily fish dark colored nymphs deep and slow. A black or olive Zebra Midge would be a good bet. I do well with “peacock flies” in the #14 – 16 range this time of year, like Zug Bugs, Prince Nymphs, etc. In the right water, a larger stonefly nymph may entice a nice brown trout.
We’re getting closer and closer to Quill Gordon time. I’ve seen a couple here and there already. As soon as the water temperature gets in the 50’s for the better of the day, for a few days in a row, we should begin seeing bigger numbers. Quill Gordon nymphs should be pretty active in preparation for emergence. A #12 olive Hares Ear does a pretty good job imitating them.
Streams in the mountains are very high and at the time of this report, still rising. Most streams should crest soon as the majority of the rain has moved on. Expect them to take AT LEAST a few days to get back to a wadeable/fishable level. Water temperatures are getting a lot better which is why I’m keeping the fishing meter in the “slow” category. Temperatures should stay relatively stable over the next few days and fishing could be good later in the week IF the water drops enough. Keep an eye on those gauges and if you don’t understand them, this article on reading stream gauges may help.
Projected Conditions
Much of this was covered above, but things are looking much better with water temperatures and should remain that way in the coming days. Everything hinges on how quickly the water drops. Right now, the water is way too high for fishing to be safe, much less productive.
We had a lot of rain on already saturated ground, so it may take a little while to get back to a reasonable level. Expect the North Carolina side of the park to rebound before the Tennessee side.

Hatches/Fly Suggestions
There is very little in the way of hatches this time of year but you may run into the occasional Blue Wing Olive. Small dark stoneflies and caddis may also make an appearance. Most everything coming off the water will be small, in the #18 – 20 range. I would primarily fish dark colored nymphs deep and slow. A black or olive Zebra Midge would be a good bet. I do well with “peacock flies” in the #14 – 16 range this time of year, like Zug Bugs, Prince Nymphs, etc. In the right water, a larger stonefly nymph may entice a nice brown trout.

Guides and fly shops routinely spit out numbers from stream
gauges, often expecting you to react with pure delight or sheer terror when you
hear them. The fact is, unless you spend a lot of time on the water as an angler,
paddler or other related water bum, those numbers won’t make a lot of sense to
you. Most folks would probably just like to know whether or not they can go
fishing. But the better you understand these numbers, the better decision
you’ll be able to make on if to go, where to go and what to expect when you get
there.
Stream Gauge Basics
There are a lot of things about reading these gauges that
are extremely simple while other aspects can get a bit complex. Many things
regarding how water flow is going to impact a stream, you just have to see for
yourself to truly understand. Then you can relate that to a gauge number and
get a pretty good idea of what that water will look like before you leave the
house.
Before these gauge readings were posted on the internet, you had to just make your best guess and/or drive to the river to see if it was going to be too high to fish. Even now, with these numbers so easily accessible, there will sometimes be some guesswork, but at least it’s a much more educated guess!
Accessing Stream Gauge Info
River Data App
The USGS has stations all over the country and there are a number of different search features to locate the gauge on or nearest the fishery in which you’re interested. Many larger rivers will have multiple stations spread out on different parts of the river. You can, of course, use a search engine to locate a specific place. Or go to usgs.gov and begin your search there. There are also a number of apps that can be downloaded. They make searching for a particular location much simpler and keep that information right in your pocket. I use an app called RiverData that gives you access to any river gauge in the country.
Stream Gauge Locations
It’s important to note that not every stream has a gauge.
So, you sometimes have to rely on the closest gauge to your fishery and assume
that both water systems received similar weather. For example, if I’m going to
fish Deep Creek in the Smokies, the nearest gauge is on the Oconaluftee. Most
of the time, Deep Creek is going to get the same or similar rain events as the
Oconaluftee… but not always.
And even when you have a gauge on the stream you’re
specifically interested in, isolated weather systems will sometimes skew the
data. For instance, Little River has a gauge located in Townsend, below the
confluence of the three prongs. So, if the water rises on any of those prongs,
it will ultimately impact the numbers on the gauge downstream in Townsend.
Usually if the gauge numbers are reading high in Townsend, the water will be up
on all three prongs as they are close enough together that they typically
receive similar weather. However, there have been occasions when there was an
isolated heavy rain on East Prong that only raised water levels on that branch.
Of course, the downstream gauge in Townsend reflected that spike but the West
Prong didn’t come up at all.
Unless you’re closely tracking every weather system, there’s
just no way to account for something like that. Stream gauges are wonderful
tools for determining water levels before you make the trip to the river. But
without multiple stream gauges spread out on different sections of every stream
in a watershed, you will often, to some extent, be making decisions based on
probability rather than 100% certainty.
Understanding Stream Gauge Tools
Not every gauge provides the same information. Some will provide a cubic feet per second (cfs) reading, some will provide a height reading (usually measured in feet), some will include a temperature reading and many have all three. A handful will get even more in the weeds and provide things like dissolved oxygen readings. For real water flow nerds, most will also allow you view charts in weekly, monthly and annual views. As long as a gauge has been in a location for forty years, I can probably look up what the flow was in that location forty years ago!
It’s also worth mentioning that different gauges may update at different intervals. Most will update at least once an hour while some may provide updates every 15 minutes. But none (that I know of) are providing data feedback in real time. Just above the selected chart will usually indicate the last time the data was updated.
CFS Reading
Stream gauge in CFS
This reading tells you what the flow of the stream is. If
the reading is 125cfs, it means that the flow is 125 cubic feet per second. A
lot of anglers that really know a stream rely heavily on this number. However,
the more casual angler may be easily deceived by this number as the “ideal
flow” can vary significantly from stream to stream. The broader and sometimes
flatter a streambed is, the more water flow it can comfortably accommodate.
So, 800cfs on a steep, narrow mountain stream may be a total blowout and not fishable at all. On a wider, flatter, low elevation mountain stream, 800cfs might be perfect. On a flat, 75-yard wide tailwater like the Clinch, 800cfs might be considered as a low flow. On a side note, I use generation schedules and data provided by TVA for local tailwater information.
Gauge Height Feet
Stream Gauge in Feet
This reading tells you how high the water is on the gauge
and gives you, I think, a little more “universal” reading. At least when it
comes to mountain streams, about 2’ on that gauge is nearly always going to be
close to “normal flow,” regardless of how wide or steep the stream is. For
instance, the Oconaluftee is at a normal, near perfect level when it is at 2’
but may be flowing at around 550cfs. Little River is also normal and near
perfect at 2’ but may be flowing at around 200cfs.
Again, there are a lot of variables like stream size and gradient
but typically, in most Smoky Mountain streams, 2.5’ is the high side of good.
In other words it is still wadeable in most of the usual spots but more
difficult. When you reach 3’ on the gauge, you might still find some
wadeable spots in isolated areas of small streams but pickings will be really
slim. If you don’t know the water really well, don’t mess around with this.
Beyond 3’, you’re likely just looking at a blown out river!
Water Temperature
Stream Gauge Water Temperature
You won’t find this feature on every gauge, but some will have it. It’s a nice feature but you have to keep in mind that it’s reading temperature where the gauge is and water temperature will change significantly as you gain elevation on a stream. For example, the Little River gauge is located in Townsend at about 1100’ in elevation. If you’re going to fish Little River around Elkmont Campground, your elevation will be around 2300’. That coupled with more stream canopy, means your water temperature at Elkmont should be considerably cooler than the gauge reading at Townsend.
It’s not an exact science but as a general rule, you drop about 4-degrees water temperature for every 1000’ you gain in elevation. So, if the stream gauge for Little River reads 62-degrees, the water temperature at Elmont should be closer to 58-degrees. This can make an enormous difference when you’re trying to find feeding trout.
