The Quest For A Wet Mountain Valley Trout Grand Slam—Day 3

Fall 2024

For Days 1 and 2 of my Grand Slam quest, see: http://hooknfly.com/2024/10/22/the-quest-for-a-wet-mountain-valley-trout-grand-slam-day-1/ and http://hooknfly.com/2024/11/05/the-quest-for-a-wet-mountain-valley-trout-grand-slam-day-2/

My holy quest for a trout grand slam continues. So far so good–browns, rainbows, and brookies checked off on Days 1 and 2. Now for the toughest one—a native Rio Grande Cutthroat.  My destination today is Medano Creek, hidden in a beautiful valley between the soaring peaks of the Wet Mountain and Sangre de Cristo ranges.  Medano Creek flows south into the Great Sands Dune National Park where it disappears into the sand. 

Medano Creek Flows Into Then Disappears In The Thirsty Sands of the National Park To the Delight of My Granddaughter Aly.

But don’t be fooled! Before it does, it flows free and cold, high in the mountains above and is one of the best cutthroat waters in Colorado. 

Miles Above the Great Sand Dunes, Rio Grande Cutthroats Thrive
in the Clear, Pure Waters of Medano Creek

Kudos go to the folks at Colorado Parks and Wildlife for this treasure.  Over a decade ago, they prepared the creek for cutthroats to survive and flourish by poisoning out invasive species like brown trout and then stocking it with Rio Grande Cutthroats, which were on the verge of being listed as endangered.  The cutts proliferated, a great success story. Fishing for the cutthroats is allowed, but catch and release is the rule.

Having fished the creek a couple of times, I know the cutts are thriving and hungry.  The question is–can I get there over the very rough Medano Pass road? In the best of conditions, it’s a teeth-jarring, bone-rattling drive, but with all the rain we have had in July and August it is likely to be in worse shape.  It doesn’t see a road grader very often that’s for sure, especially on the east side of the pass. 

For safety’s sake, it’s good to have someone with you on this trip, so I invite my fishing buddy from Salida, Mr. Tom P. to join me.  I call him Tenkara Tom.  Tenkara is a simple, traditional Japanese style that uses a very long rod, a short light line, and typically only one wet fly.  It has only become popular in the USA in the last 15 years.  It works best on small streams because of the short line that is simply flipped out with the fly without any false casting as with traditional fly casting.  Tom is a master at it, as he demonstrated by outfishing me last year on a small creek in the San Juan Mountains.  I am hoping to deliver his well-deserved comeuppance on Medano Creek. 

I meet him in Westcliffe at 7:30 a.m. on a Sunday for the two-hour drive over Medano Pass, our goal being a series of beaver ponds and open creek stretches several miles below.  Don’t be fooled by the Google Maps that portrays this as a one hour and five-minute drive.  It will take about two hours if you avoid any mishaps.  The first part of the drive is down CO 69 highway, which is a good paved road, about 25 miles to the turnoff on gravel road 559 which leads to Medano Pass.  Be sure to keep your eyes peeled for the Medano Pass turnoff sign.  Don’t follow the circuitous route suggested by Google Maps

Follow the Signs On CO 69 For the Turnoff To Medano Pass

The trip is a very scenic one that often features herds of elk or buffalo with the striking Wet Mountains framing the view. 

The first five miles or so on road 559 are decent, skirting a big lake on private property before beginning the ascent to the pass.  But from there things can get gnarlier by the mile as Tom and I soon discover.  The road clearly hasn’t seen a grader for some months as witnessed by the eroded channels coursing down the two-track carved out by recent rains. 

Every mile or so where the road splits to avoid a big boulder or stand of trees, Tom jumps out and evaluates the better route, which works well until we decide to go right to avoid a stretch to the left with some sharp rocks protruding from the roadway.  The right fork is steeper, but the roadbed looks to be in better shape.  I line up to gun up the grade as Tom steps to the side.  I am in 4-wheel drive with some new AT tires, so don’t expect what happens next.  I lurch a few feet forward, then my tires start to spin wildly getting no traction, and my SUV begins to slide backwards with the tires kicking up baseball-sized rocks.  I turn the wheel slightly hoping to avoid sliding into some big trees behind, but that maneuver results in the SUV starting to tilt on its side.  Luckily I get the vehicle stopped before I roll it.  I sit there shaking for a minute, having survived what felt like a near-death experience.  It probably wasn’t that bad, but the look on Tom’s face says it all.  We soon regroup, back up and take the rocky looking stretch which proves to not be as bad as it looked.  But you get the picture–this is a route for 4WD vehicles with high clearance only and drivers with substantial experience on rough backcountry roads.  Indeed, a better route may be through the Great Sand Dunes National Park.  While there are some challenges with that way as well, such as several deep creek crossings and the notorious Sand Pit that can swallow unsuspecting vehicles and requires you to deflate your tires before proceeding then reinflate when you hit solid roadbed, at least you are closer to civilization if you need to walk out or get help.

Most Creek Crossings Are Navigable Except After Heavy Rains

Once over Medano Pass, however, we breathe much easier and can enjoy the spectacular fall scenery.  The road in the National Park and Preserve proves to be much better maintained than in the national forest on the east side of Medano Pass.

The only challenges are a couple of stream crossings, but unless there has been a big rain they are easy in a high-clearance SUV.  Within a few miles down off the pass, we come to a series of beaver ponds and a hidden stretch of open creek water below where I have done well on earlier trips. 

That’s where we pull over and suit up.  I am wearing chest waders and Tom his wet-wading knee-high outfit.  Tom rigs up his 9-foot tenkara rod with a #14 soft hackled pheasant tail he will fish wet.  It’s a pattern I have seen him catch numerous fish on.  I have my short 7.5 foot 3# wand ready to go with a #18 Chubby Chernobyl dry and a #18 Dirk’s Delight green caddis larva dropper.  By 9:45 we are bushwhacking towards a nice open stretch of the creek hidden downstream of the big beaver ponds.  But as we reach our destination we find the busy beavers have been hard at work—they have built a series of small beaver dams that make casting very difficult.  The dams have backed up water into the overhanging trees and bushes, and the new ponds are too deep or mucky to wade. 

Fortunately, we can see the fish, some rising insouciantly beneath the overhanging bushes.  Tom boldly fords the creek and crashes further downstream.  Soon he is hooting and hollering that he has a good one.  “First fish of the day—a cutt over 12 inches!” he shouts.  Likely story I think!  And he never snaps a photo or produces any other evidence of the event.

We head upstream and finally come to an open stretch that was a hot spot last year.  The water is very low and clear, but with a careful approach we get within casting distance of the pool and have some fun sight fishing.  We can see a half dozen fish looking upstream waiting for their next meal to float by.  I give Tom first chance, and he immediately snaps off his pheasant tail in some bushes behind us.  I wait patiently while he searches for a replacement in his fly box, but all he comes up with is a bushy #18 caddis dry fly.   I have to stifle my chuckle, but then on his first cast he connects immediately.  A beautiful small cutthroat. 

Then it’s my turn, and on my first cast a colorful cutty nails the dry!  Grand Slam!! 

Beautiful Rio Grande Cutthroat Completes The Grand Slam!

From then on, it’s non-stop action for the beautiful natives.  In a few minutes Tom manages to fool a gorgeous one, sporting a namesake bright reddish-orange slash on its throat, that goes almost a foot, one of the biggest of the day.

We continue on upstream and come to a challenging bend pool guarded by snags mid-stream.  On previous trips it has produced some good-sized, feisty fish for me. 

Tricky, Snag-Filled Bend Pool Holds Muscular Cutts

Being the gentleman fly fisherman, I motion for Tom to go first.  He shows off his stealthy moves by creeping up to a spot on the opposite shore where he can flip his fly out without spooking the fish and still reach the honey hole between the snags.  He sits quietly to let things settle down, then flicks a backhand cast that results in his fly alighting perfectly between the snags.  In a flash, he’s onto a good fish.  He lands that one and then fools two more from the same pool.  Good show Mr. T!!

We continue upstream and come to my favorite long, open stretch of the creek just below an old big beaver dam.  But of course, things have changed since last year.  The beaver have constructed another big dam—almost 4 feet high–that has flooded the creek all the way up to the foot of the old beaver dam, creating a long linear pond 20 or so feet across.  My heart sinks as I utter a few choice words.  But hope springs eternal, so I begin to scale the new dam, a bold move by a septuagenarian.  I manage to get near the top so I have enough clearance to cast but still keep low enough not to spook the fish….if there are any in the new pond.

I throw a long cast into the slow current, let the flies settle, then give my line a twitch.  The water explodes as a good cutt gulps down the dry.  He cavorts back and forth around the pond, then something almost jerks the rod out of my hand.  Low and behold, another trout surfaces with the caddis larva in its jaw.  He goes one way, the dry fly guy the other.  It’s a fun battle, and I beam as I lift my line out of the water with two fish wriggling wildly.  Soon they are swimming back to their pals. 

Not to be denied, Tom hikes around the dam to get into the action from the shoreline.  Together we get another couple dozen in short succession before we decide to take a lunch break around 12:30. We will hit the old beaver ponds above after feasting on the comestibles.

But the weather has other ideas.  As we lounge over lunch, some ominous looking clouds start to roll in from the west along with gusty winds.  Instead of flying the white flag, however, we decide to hustle back to the ponds and give them a try…and soon are catching more eager cutthroats in the new narrow pond where I scored the double.  Next we do a highwire act along the old dam upstream till we come to an open spot were we can cast.  Bingo, the fun continues!  Tom, sans waders, has a little trouble reaching the best spots in deeper water offshore with his short line Tenkara rig, but I boldly wade in and am able to cast to some risers out of his reach and net a couple more.  Retribution completed! 

By now, however, the clouds start to spit rain and the wind is howling, sending us scurrying back to the SUV.  It’s about 2:30 when we hit the road back to Westcliffe. 

Rain Clouds and Gusty Winds Signal The End To A Fantastic Day

Again we enjoy the scenery with the aspen showing off their fall colors from bright yellow to flaming orange. And now that we know the rough spots on the road from the travails of the morning, the drive back going downhill from Medano Pass is definitely easier and more pleasant, especially with the Grand Slam accomplished.  It’s been an enjoyable three days pursuing these beautiful fish in magical, remote surroundings, topped off with a good dose of camaraderie with Tenkara Tom today.  After all, that’s what fly fishing is really all about. 

Prospecting For Trout on the Fab Five Forks Of The Conejos River: #2–The Adams Fork

Lake Fork Of The Conejos River: Solitude In A Sanctuary For Rare Rio Grande Cutthroat Trout

Mid-August 2021 near Antonito, Colorado

I’m on my annual trip to fish the Conejos River and surrounding waters.  The Conejos is a middle-sized river that harbors big brown and rainbow trout that fatten up on its abundant insect life.  Even though there is plenty of public water between Antonito and Platoro Reservoir, solitude can be a little hard to find.  So I did a little sleuthing and discovered the Conejos actually has five alluring, forks—the North, South, Middle, Lake, and Adams—that are all remote waters requiring some hiking to get to. 

A couple of years ago I had a stellar day on the Lake Fork, a three-mile hike into a high-mountain meadow paying off with a bonanza of gorgeous Rio Grande Cutthroats, several going better than 15-inches.  After a year of missing fishing the Conejos because of the extreme drought in the area, I have set my sights on the Adams Fork above Platoro Reservoir, 40 miles west of Antonito.  This year thanks to timely July monsoon rains, all the rivers and creeks around the area have decent water levels.  I’m intrigued when I can find very little online about fishing the Adams Fork.  There are several posts by hikers who mention the Adams Fork trail, but no indication they sampled the river.  Fortuitously, a few weeks before the trip a reader of my blog mentioned he had caught some nice cutthroats there in July.  Say no more!  I’m sold.

It’s mid-August and at 7:00 a.m. I’m leaving my mobile fish camp at the first-rate Canon Bonito RV park near Mogote.  It’s a 40-mile drive that will take a good two hours to the trailhead above Platoro Reservoir. 

The Adams Fork Above Platoro Reservoir In The South San Juan Wilderness

The first 20 miles on paved Colorado 17 are smooth and scenic.  But after that, tighten your seat belts!  The next 20 miles are up CR 250, widely known for eating tires and various other vehicle parts.  It’s a rough washboard road where you should take the 25 mph speed limit seriously.  The scenery is spectacular, so ease off on the accelerator and take your time.

Around 9 a.m. I am bouncing by the little historic resort community of Platoro, founded in 1945. It’s an eclectic mix of old cabins, new log houses, rental units, and a venerable hotel.   Above the hamlet I hang a left onto FR 247, a decent gravel road that snakes along high above Platoro Reservoir.

Looking South Out Over Platoro Reservoir Towards The South San Juan Wilderness Area

Unfortunately, like most reservoirs in the West it is drought-stricken, sporting a big white bathtub ring.  In a few miles I come to the official trailhead for the Adams Fork. The parking area is empty, a good sign!

I suit up in my lightweight breathable chest waders and carry just one rod today, my new super light four-weight TFO that goes 8½ feet. It’s a beautiful sunny morning with light winds, with a balmy temperature of 70 degrees to come this afternoon at 10,500 feet.  The first section of the trail is steep, so I am soon huffing and puffing, my septuagenarian body complaining about the weight of my as-usual overstuffed fishing vest.

Before long I come to a switchback that crosses the first of several feeder creeks that add their waters to the Adams Fork on the way to my target area, a series of open meadows a couple of miles up the valley.

Main Adams Fork Trail Crosses First Feeder Creek

For the most part from here the trail is fairly flat, with a few ups and downs where it intersects those small feeder creeks.  The wildflowers put on a showy display for me, so I stop and take some photos for my granddaughter Aly, who loves to help me identify them with the help of a terrific free app called PictureThis.  Scarlet skyrockets, fringed gentians, savoryleaf asters, and arrowleaf groundsel abound.  I can hear the river roaring several hundred feet below in its rugged canyon, but can’t see it. 

In about a mile, I come to a downed sign and turn it over. It’s a marker for the boundary of the South San Juan Wilderness Area.

Into The Wilds

In a short distance beyond the boundary marker, I run into a series of steep grassy slopes and meadows that descend steeply to the Adams Fork, which has finally revealed itself. For the next several miles, the access improves as the valley widens. I finally spot a likely looking stretch of water with fewer rapids and more bends and pools.

Gripping my wading staff tightly, I start zig-zagging carefully down the steep incline. The footing is decent, but when I slip on some loose dirt a couple of times, I remind myself to take it easy. As I take a breather half way down, I look out over the sun-soaked tall grass. Suddenly I think I hear Julie Andrews singing her iconic song “the hills are alive to the sound of hoppers!” The whole meadow is whirring with amorous grasshoppers. As I drop down further the noisy insects flee in front of me.

It’s about 10:15 when I emerge on a rocky bar below a good-looking pool. 

“Can’t Miss” First Pool

Naturally I break out my trusty Royal Trude in #16 which is an excellent imitation of the small grasshoppers in the meadow.  When I check under the rocks in the river, I’m surprised to find some small stoneflies, so tie on a #18 Tung Teaser as my dropper.  The water is crystal clear and flowing about 10-15 cfs, a bit low but eminently fishable. 

With great confidence borne of my friend’s glowing report, I loft a beautiful cast that lands perfectly in a foamy run.  Nothing.  Not even a looker.  Several more throws with the same result.  It’s puzzling.  Everything looks perfect.  Have I been hoodwinked??  I walk up to the next good-looking pool and on the way spook a couple of decent-sized fish.  A good sign, but again, no bites.  Now I’m smelling the distinct odor of skunk.  Did the July monsoon rains bring floods that wiped things out, something not unheard of on these small creeks? I try to keep the faith and continue working upstream, and at approximately 10:45 a.m. a small, but celebrated 10-inch cutthroat breaks the spell.  He’s taken the nymph.  Then another follows on the next cast.  Well, I think, I can live with a day of small fish. 

Highly Celebrated First Fish Of Day

Soon I come to a small postage-stamp sized pool featuring an overhanging branch that will surprise me.  It turns out to be the first honey hole of the trip. 

Sometimes Size Does Not Matter–Tiny Honey Hole

I manage to execute a cast that drops my flies delicately above the branch, and as they float under a big trout swirls at the dry, then follows and chomps down on the nymph. He wrangles with me for a while then finally comes to the net, a beautiful, stout 14-inch Rio Grande Cutthroat. That’s more like it. Three more 12-inchers quickly follow, attendants at the king’s court.

First Big Cutt Of The Day

Then just as I think there can’t possibly be any more in the pool, or at least ones that haven’t been put off by the mayhem, a real bruiser surfaces on the next cast and nails the dry.  He puts up a terrific battle, flashing his brilliant colors as he bids for freedom.  When he finally is subdued, the gorgeous fish measures 16-inches, a true leviathan for such a small water.

Adams Fork Leviathan!!

After all the excitement, I relax on a streamside rock, drinking in the scene.  Wildflowers cover the slope and bench above.  Butterflies are fluttering everywhere. A stand of bright yellow mountain goldenrods catch my eye, covered with striking black and white butterflies—obviously enjoying a late summer love-in. 

Butterfly Love-In

I look down and instead of boot marks see dozens of hoof marks, including several giant ones left by moose and elk.  I wonder if some are watching me.

Reenergized, I work cautiously upstream, being careful not to spook the cutthroats I can see finning in the deeper pools, oblivious to my presence.  Every pool seems better than the last, each yielding several cutts, usually with a big one mixed in.

Beautiful Pools Abound

But after an hour of unbridled success, I hit a dry spell.  I get steady rises to the Trude dry, but the fish take a close look and then bump the fly or just turn up their noses and drop back slowly to their holding positions.  I have never had that happen on remote streams, where the bushy Trude seems to always ring the dinner bell.  I do catch several on the Tung Teaser nymph, but they tend to be smaller fish.  Reluctantly, I decide to change flies, tying on a smaller profile #16 Wilcox dry that, while designed to mimic a mayfly, is a great imitation of tiny hoppers often found around high-altitude streams.  The results are immediate.  I drift the fly along a bank that just drew refusals on the Trude, and a good-sized cutt intercepts it with not hesitancy in a showy rise. 

Wilcox Dry Fly Fires Up Action Again

From then on the action is hot again with most strikes on the surface and in sun-drenched pools.  Those in shadows or deep don’t produce.  Obviously the cutts are sun-bathing, and who can blame them with the already cold nighttime temperatures at this altitude–over 10,000 feet!

Just after noon, my stomach starts to growl so I make one more cast in another photogenic pool before breaking for lunch.  No sooner does the Wilcox alight than it is blasted by a giant fish.  I set the hook and the scuffle is on.  It’s to and fro for a minute, but I finally gain the upper hand and start to ease the big boy into my net.  But when he gets a glimpse of his fate, the cutt jets to the top of the pool, through the rapids above, making like a wild salmon, and into the next pool.  Now he has the advantage with so much of mine line stripped out, giving him leverage, and sure enough he shakes off with an acrobatic jump.  He looked to be 18-inches or more, the biggest trout of the day. 

I sulk for a minute or two, then start casting again, resolute not to end the morning a loser.  As if by magic a few minutes late a muscular 15-inch cutt helps soothe my bruised ego as he smacks the dry and puts up a worthy fight. 

Colorful 15-Inch Cutt Salves Loss Of Big One That Got Away

After lunch the good action continues and by 2 p.m. I’m tuckered out.  It will take me three hours to get back to camp so I swear this cast will be my last.  Three fish later I net a scrappy one in a plunge pool and decide it really is time to head back. 

Scrappy Cutt Closes Out Wonderful Day

As I get to the bench above the river I turn and tip my hat to another fab fork of the Conejos. 

One Last Photo And Tip Of The Hat To The Adams Fork

What an uncommon treat to catch and release such beautiful rare fish.  Then I chug up the slope towards home, already planning a return trip.

CAVEATS:   Ignoring my own caveat, I exceed the 25 mph speed limit on the way back to pavement and end up with a flat tire! Second caveat–I fished the Adams Fork a month later in early September and found it very low with extremely skittish fish, particularly in the crystal-clear deeper pools with slow-moving water where the cutts could scrutinize the faux hopper.  It was still a successful outing, but my advice is to make sure the Conejos River downstream at Mogote is flowing at least 100 cfs which would indicate the Adams Fork probably has a decent flow.  Also, avoid the Adams Fork area after September 1 when it is overrun with amiable bow hunters, some of whom also fish!
