S8, Ep 28: Lessons from the River: Mac Brown's Insights on Adapting to Unusual Conditions
Episode Overview
In this Casting Angles segment of The Articulate Fly fly fishing podcast, host Marvin Cash and Master Casting Instructor Mac Brown discuss how to adapt when an unusually warm, drought-driven spring upends normal seasonal fishing expectations across the mid-Atlantic and Southern Appalachians. It's a candid, practical conversation for anglers dealing with conditions that have scrambled hatches, compressed water temps and pushed trout into summerlike stress months early.
Mac reports water temperatures in the mid-70s in Bryson City during mid-April — historically a July scenario — with corresponding low water on Western North Carolina freestone streams, including the Davidson River near Brevard where water temps were nudging the upper 60s. The practical takeaway from the conversation is concrete: when freestone streams become untenable, seek out tailwater fisheries with reliably cold, dam-regulated flows, and adjust fly selection dramatically — in this case dropping to size 28 Blue Wing Olives in April, a fly more commonly associated with winter midge-style fishing on the South Holston, after typical spring hatches like March Browns and Hendricksons failed to materialize. Mac and Marvin also encourage listeners to make a gear shift altogether when trout conditions are compromised, pivoting to panfish and bass on local ponds and lakes. The philosophical throughline is the classic fishing truism both hosts return to: you can only take what the river is willing to give you.
Key Takeaways
- How to identify when warming freestone streams have become too stressful for trout and it's time to shift to tailwaters or alternative species.
- Why size 28 Blue Wing Olives can be the correct spring fly choice during drought years when conventional late-spring hatches like March Browns and Hendricksons fail to appear on schedule.
- When traditional spring trout fishing is compromised, how pivoting early to bass and panfish on local ponds offers a productive and accessible alternative.
- Why monitoring water temperature — not just visual stream conditions — is the most reliable guide to where trout will be feeding during abnormally warm spring weather.
Techniques & Gear Covered
The episode's most concrete tactical moment comes from Mac's report of fishing a size 28 Blue Wing Olive during a late-April outing — a winter-style presentation typically reserved for midge-focused tailwater days on rivers like the South Holston — after spotting a pod of actively feeding fish with no significant spring hatches in the air. No March Browns, no Hendricksons: just a tiny blue-winged olive and a size 28 pattern to match it. Beyond that single hatch-matching scenario, the tactical discussion centers on the broader decision-making framework of reading water temperature as a leading indicator, targeting the cold-water refuge of tailwaters when freestone streams become thermal and knowing when conditions call for switching species entirely rather than forcing trout fishing in compromised water.
Locations & Species
The conversation covers Western North Carolina freestone streams, including the Davidson River near Brevard and the waters around Bryson City, where mid-April temperatures had reached summerlike levels and flows were running at roughly a third to a half of seasonal norms across much of the mid-Atlantic. Mac points listeners toward tailwaters fed by large impoundments — specifically the fisheries below Fontana Dam, and waters like Cheoah and Calderwood — as cold-water refuges where trout will continue feeding more normally regardless of ambient air temperatures. Marvin references the South Holston and Watauga as additional tailwater options for Tennessee and Western NC anglers, with a caveat about reported turbine maintenance on the South Holston at the time of recording. Brown and rainbow trout are the primary targets throughout, with a passing acknowledgment that the abnormally warm March also disrupted pre-spawn smallmouth bass patterns in Virginia and the Carolinas.
FAQ / Key Questions Answered
How warm is too warm for spring trout fishing on freestone streams?
Mac and Marvin both flag water temperatures in the upper 60s as the threshold where trout fishing on freestone streams becomes unproductive and stressful for fish. The Davidson River near Brevard hit those temperatures in mid-April during this unusual spring — a full two months earlier than the July conditions those readings would normally indicate.
What fly should you use when spring hatches don't materialize on schedule?
Mac's answer from this episode: revert to winter-game logic. When he found a pod of working fish in late April with no March Browns or Hendricksons in the air, a size 28 Blue Wing Olive — the same pattern he'd fish on a winter day on the South Holston — turned out to be the correct call.
Why are tailwaters the best alternative when freestone streams get too warm?
Dam-regulated tailwaters draw from cold reservoir depths, maintaining stable water temperatures even when air temperatures are unseasonably high. Mac specifically mentions the fisheries below Fontana Dam — Cheoah and Calderwood — as reliable cold-water options when surrounding freestone streams become too warm to fish effectively.
What should trout anglers do when neither the water temperature nor the hatches are cooperating?
Both Mac and Marvin recommend the species shift: get out early on the panfish and bass season. Ponds and lakes close to home offer productive topwater and popper fishing for bass and bluegill when trout streams are off the table, and the change of scenery often produces fish when the usual spring program simply isn't available.

Hey, folks, it's Marvin Cash, the host of The Articulate Fly. We're back with another Casting Angles with the man himself, Mac Brown. Mac, how are you doing?
Mac BrownI'm doing great. How are you doing, Marvin?
Marvin CashAs always, just trying to stay out of trouble, you know. And it's funny, like we always do, we probably talk probably five times as long before we record, before we record.But we were trying to decide what we wanted to talk about tonight, and we were kind of talking about lessons from the water, and I thought something that would be good, particularly since it's been an incredibly challenging spring, not just for trout anglers, but for smallmouth anglers and other folks to kind of talk about the lessons of the river, of, you know, just. You can only take what the river's willing to give you.
Mac BrownThat's. That's really true. I mean, it's a lot like. Like a lot of things in life. I mean, but you only take what it can give you when it can give it to you.And I think that's a. I remember my grandma always saying that when I was little about life gives you lemons, you make lemonade. And it's like, you got to do what you got to do when it's time.You know, it's a really different time right now on the water, unlike that I've ever seen. I think it's that way for a lot of people that things are so different than what we historically think of for this time of year.
Marvin CashYeah, I would say, you know, so if you're a trout person in the mid Atlantic, you know, we're probably most of the mid Atlantic is either in drought or an extreme drought. And we're looking at. If you look at gauges, probably flows that are a third to a half what they should be this time of year.And we've also been unseasonably warm with temperatures kind of in the upper 80s. So I actually just put out a newsletter for the month of April.And I mean, in April, middle of the month, we had to start temping the water because we were starting to bump up into the upper 60s on the Davidson river and Brevard. And that's no fish time, right?
Mac BrownYeah. And we had, like, 72 here in Bryson a bunch in middle of April with, you know, 80, mid 80 temperatures and low water. And that's unheard of.That's like July temperatures in April. So, yeah, things have to change. Good news is Saturday, you know, we got a little rain here. I think we got 3/10 of an Inch on Saturday night.And that brought the temperature back down to 61 on Sunday this week. So at the same time, at 12 noon, 61 degrees, that dropped at 11 degrees just from that little rain. So. So that was a positive.
Marvin CashYeah, and I, I would say too that, you know, for the smallmouth guys, you know, it was really, really warm in March down here in, you know, Virginia, the Carolinas and that completely scrambled, you know, cat kind of patterning the pre spawn smallmouth. So it's kind of been weird for everybody.
Mac BrownThat definitely, definitely has with warm water fish and cold water fish and just unseasonably different, different conditions. You know, I'll tell you, I'll tell you one thing that was kind of funny on I think Saturday, Saturday, Marvin, there was some fish.And finally the first time I'd seen a pod of fish working, all the trips I've been since Lancaster, Pennsylvania and I see all these fish working and I'm like, well, I don't see anything big in the air. There's no March browns. There wasn't any Hendricksons, anything like that.Well, finally saw a little black caddis landed on the boat in a little blue wing. I put it on a story the other day on Instagram. Little blue wing was about a size 28.So I started thinking, well, we can play the winter game and this is like on Sunday of this week. So I ended up putting a 28 blue wing just like how we fish on the Halston. And that was the magic ticket.But who would ever thought we'd be throwing Blue Wings 28s in April compared to like, you know, historically we're getting away with all kinds of stuff. You know, the quills have already ended, but normally Hendrickson's and March browns and things are still really big this time of year.We haven't even seen one of those yet. So maybe they're not going to happen this year at all.
Marvin CashYeah, it's interesting. I mean, you know, if you trying to figure out, well, what do I do?You know, if you're lucky and you live close to a tailwater, you know, that'll kind of save your bacon on the trout front, right? Because the secret there is they generally have consistently cool water.I think there's still some issues working on the dam and the turbines on the South Holston. But you know, I think the Watauga has been pretty consistent, although I don't have super current reports.But I would also say folks too, you know, just shift gears into your summer fishing a little bit early and get out there and fish poppers for pan fish and bass.
Mac BrownYeah, that's a good tactic. I'm going to the lake cause I'm off. I have a few days off this week and I'm going down to the tailwaters, you know, below like.But we got a lot of good tailwaters up here that are below big, you know, Fontana dams. 470Ft. Right below, that's Chio. Below Chio you got Calderwood. And we got some really good cold water fisheries.And I mean down there, this temperature's not going to affect that and the fish will still feed and eat. Eat more like normal. So I just got to switch like what I'm doing. But that's an hour.The bummer part is it's an hour drive from the house here to get to there, you know.
Marvin CashYeah, but it's a further. Yeah, but it's a faster day if you're catching fish, right?
Mac BrownOh yeah, yeah. Because I'm sure the water will be cold. Water be low 50s down there. So we just gotta go seek out water temp, you know.And to do that a lot of times means drive further.
Marvin CashYeah, well, for me, you know, panfish and bass is a whole lot closer because we got ponds and lakes and stuff all over Charlotte. But you know, folks just, you know, make some lemonade out of the lemons and I know, Mac, I know you wrapped up a school this past weekend.Do you have any more schools kind of in the near future you want to tell folks about?
Mac BrownNot until fall, I think. Not until like we get into October, so that'll be a while from now. So we're kind of looking forward to getting some time, you know, get out.Maybe I might walk to Hot Springs here next week. Walk on the at from the house here and go do some backpacking and some other things for a while.Just as long as it's going to stay kind of in this trend. I think after we get on some tailwaters, I'm gonna probably go do some walking, Marvin.
Marvin CashYeah. Well, there you go. Well, before I let you go, you know, we got a burn ban in North Carolina, so we can't do smoke signals.You want to let folks know, you know, how they can reach out and you know, guide trips. I know you're just telling people, look, it's gonna be tough. They're probably really more teaching guiding trips than guiding for fish trips.But if folks want to do that or catch up for a casting lesson or learn more about what's going to happen this fall on the class front. Where should they go?
Mac BrownThe best.The best place is just the website, MacBrownFlyfish.com and then they'll get the email, and they can send a message on that or text or call on the number that's on that. It's probably the best way.
Marvin CashGot it. Well, listen, folks, you know, make lemonade out of the lemons. Get out there and catch a few. Tight lines, everybody. Tight lines, Mac.
Mac BrownTight lines. Marvin.
