Fall 2024

I am on my annual trip to the Wet Mountain Valley in southcentral Colorado.  It’s only an hour and a half drive from my cabin near Salida, Colorado, but a world apart.  The people population in Custer County that covers most of the valley is 5,000, dwarfed by the number of cattle grazing in the scenic meadows. There’s great fishing to go along with the scenery, rugged soaring peaks of the Sangre de Christo and Wet Mountains, and a distinctly different vibe. 

I am staying in my mobile fish camp at the fine Grape Creek RV Park just south of Westcliffe, the county seat, and will be here from Friday to Monday.

My plan is to sample several of my favorite trout streams like Grape and Medano Creeks…and maybe score a coveted grand slam—catching (and releasing) four different species of trout.  I will also take in some of the sights in this historic valley and chow down at several of my favorite restaurants après angling.

Custer County was named for the famous General Custer.  Like many mountain communities in Colorado, it owes its start to silver and gold mines in the late 1800s as witnessed by the name of the biggest town in the county, Silver Cliff, which abuts Westcliffe, and which sports a population of 747. Westcliff, population 435, was a railroad town serving the mining and cattle businesses.  But ranching has always been a big part of the picture, some early spreads boasting over 10,000 cattle that helped to feed the miners.  While the county has grown and Westcliffe sports artist studios, antique shops, and good restaurants, overall the valley maintains much of its old West atmosphere as witnessed by the fact it has been the of location of many western movies such as How The West Was Won featuring John Wayne, Cat Ballou with Lee Marvin, and Comes A Horseman with James Caan and Jane Fonda.    

Day 1:  Grape Creek At Bear Gulch

I decide on my first day of my grand slam quest to explore a remote section of Grape Creek below DeWeese Reservoir. The main stream in the valley, Grape Creek springs from the Wet Mountains and then flows north to DeWeese Reservoir.  Deweese has been a fixture in the valley since 1896 when it was created by damming the creek to provide a steady source of water for fruit and shade trees over 20 miles downstream near Canon City where it flows into the Arkansas River.  Bear Gulch, about seven miles downstream from the dam, and actually in Fremont County, is the only public access to just above Canon City and can be reached only by negotiating a rough 4wd road followed by a short but very steep hike down to the creek.  Not for the timid! 

I am on the road early, taking the Oak Creek Grade just east of Silver Cliff, a decent gravel road that takes about an hour to reach the turnoff to Bear Gulch.  It’s a scenic drive often featuring deer and other wild critters, not to mention those of the bovine kind.

But things get a little baffling at the turnoff thanks to misdirection from Goggle Maps and some confusing signage.  As illustrated in the photos below, the correct route is to turn north/left off Oak Creek Grade at the sign for Grape Creek Access then bear left (not right as directed by Google Maps) at the somewhat obscured “BLM Access” sign behind a big green electrical box, and finally to the right at the blue “To Public Lands” sign.  

Then buckle up and get ready for some thrills and chills on the several miles of rough road that follow. I suggest using a 4wd vehicle, one with good all-terrain tires, especially if the road is wet. 

Cars like a Subaru with all-wheel drive and good clearance can navigate it ok if the road is dry. 

In about 15 minutes and 4 miles later, I come to the parking area on a bench above the creek with some descriptive signage providing information about the Grape Creek Wilderness Study Area. 

I am the first one here today.  I suit up in my chest high waders and head down the steep trail to the creek, using my trusting wading staff to prevent me from slip sliding away in the loose gravel.  I am carrying two rods, an 8.5 footer-rigged with a #16 Chubby Chernobyl, a good hopper imitation, and #16 Dirk’s Delight green caddis larva, a proven favorite on Grape Creek.  The second is a heavier 8.5’ nymph rod with a #14 conehead stonefly and #16 Psycho Prince nymph to probe some of the deeper holes in the creek.

Dirk’s Delight Green Hotwire Caddis Larva

When I get down the slippery slope to the water, I have a choice to either go downstream where the fishing pressure is lighter but with fewer big fish or upstream into a canyon stretch that has some deep pools and stout brown trout.  Today I opt for going upstream since I got here early and will be the first one on the water in the canyon.  I walk about a mile, hoppers whirring about me in the deep grass, and then come to the first deep pool at the foot of a sheer cliff that also features a big back eddy where I have fooled some good fish in the past.  But not today.  After a dozen casts with both rods, I come up empty handed.  The same story repeats itself in several more good-looking pools for the next twenty minutes.  Puzzling.  The water is cool and appears to be in good shape.

By 10 a.m., the sun has started to warm things up under a beautiful Colorado bluebird sky, and finally the fish get hungry.  I fool a scrappy 11-inch brownie on the caddis larva dropper, but things then go quiet again. 

Spunky Brown Starts The Day

I manage a long-distance release and a few more strikes, but nothing to the net.   Puzzling.  Soon though I come to a honey hole bend pool that has been a sure thing on earlier trips, and what to my wondering eyes does appear but a thick blue-wing olive mayfly hatch.  What look to be big rainbow trout are cruising and dimpling the surface as they slurp down the mayflies.  I try a few casts with the dry/dropper rig and manage a few half-hearted rises before the hatch subsides and things go dead.  I was too slow in changing flies.  Grrr.  Okay, it’s noon and time for lunch and an attitude readjustment.   

That seems to do the trick.  On the first pool upstream, I trick another scrappy brownie in some fast water then a chunky 14-incher, both on the green hotwire caddis larva.  Now it’s steady action the rest of the afternoon.  In one pool a couple of feisty 12-inch rainbows gulp down the larva and a brownie falls for the Chubby. 

The further upstream I go, the better the action gets along with bigger fish.  I net two 14-inch browns where the creek splits around an island and 10 minutes later two more of the same measure in a beautiful pool upstream.  

I am thinking that nice brownie is the last fish of the day, but see some good looking pools upstream. Who can resist?!? I work up another 20 minutes and get another half dozen browns in shallow stretches before heading back downstream towards my SUV. It’s after 3 p.m. and the hike back to the trailhead will take at least an hour even for this buff (creaky?) septuagenarian.

On the way back, I come to the big, deep mayfly hatch pool where I bungled things earlier. But now it’s calm and quiet.  Worth a try after being skunked here earlier?  Of course….and on my second cast my dry is yanked under as a big rainbow feasts on the Dirk’s Delight caddis larva.  The battle is on.  He has a lot of room to thrash back and forth.  When he lunges and pulls to the right I apply pressure and turn him back to the left.  Hither and yon we fight, and finally after a worthy bout a beautiful 15-inch rainbow slides into my net. 

Big Rainbow Caps A Good Day On Grape Creek

He soon is finning back to his hideout.  I decide that would be a good way to end the day, but then see a rise on the far side of the main current and of course decide just one more cast.  The Chubby floats jauntily down the riffle into the pool, and the trout smashes it, is on, then thrashes free!  I have to smile and shake my head.  A good reason to come back.  It’s almost 4 p.m. now and a good 30 minutes back to the trailhead.

On the easy jaunt back I enjoy the fall landscape, the soaring cliffs, the imposing thick stands of bristly thistle plants—some 4-5 feet tall, cholla and prickly pear cactus, and even a big wolf spider that I first mistake for a frog as he surprises me rustling through the underbrush. Be sure to watch out for rattlesnakes during the summer!!

I arrive at the trailhead around 4:30, just in time to be greeted by six campers, two whom are fisherman. All are setting up their tents in the shady camping area along the creek for the weekend.  A reminder of why I come here during the week.  And one couple has even made it in driving a Subaru!

The hour’s drive home is relaxing, featuring a series of beautiful vistas. Then I stumble on what may be the new secret Tesla product being tested in the backcountry, a travel trailer that appears to be a match for the famous CyberTruck. And I catch a glimpse of someone skulking inside. Maybe Elon himself?? Who knows in these days and times?!?

As the sun begins to drop below the Wet Mountains, I pull into my spot in the RV campground, stow my gear, and relax, soaking in the view and enjoying a glass of Pinot Grigio. I’m contemplating Day 2 of the Grand Slam Challenge. Two different trout today–browns and rainbows–and two more to go–maybe a brookie and a cutthroat. But I am a tad tuckered out after a long day on lower Grape Creek and my right arm sore from catching so many fish, so I decide to take tomorrow morning off and do a little touring in Westcliffe and Silver Cliff. Then in the afternoon I will pursue some of the wily brook trout that inhabit upper Grape Creek that just happens to run right through the RV park. How convenient for an angler of senior vintage!

Grape Creek:  The Curious Case Of The Rambunctious Rainbow Resurgence

Late July 2023

For some of my earlier trips on Grape Creek, see: http://hooknfly.com/2022/08/05/grape-creek-comeback/

Grape Creek near Westcliffe, Colorado, is one of my favorite waters.  Flowing some 20+ miles in a remote canyon between DeWeese Reservoir and Canon City with only five public access points, over the past decade it has proven to be a great brown trout fishery plus providing an occasional thrill of a big rainbow.  But like most rivers in the West, Grape Creek has faced a series of threats including a huge gold mine in its watershed and wildly fluctuating water levels caused by irrigation demands and drought that have left water levels so low as to almost dry up the stream in summer.  More recently a series of catastrophic floods in 2019 scoured insects and fish from the stream, leaving it a mere shadow of its former self.

I experienced firsthand the deleterious impacts of these floods when in 2020 I led a visiting fishing buddy from Florida on an expedition into the canyon, having promised him hungry fish, only to narrowly avoid being skunked after six hours of flailing the water.  Two puny, malnourished brown trout helped avoid that ignominy.  Fortunately, by my next outing on the creek in the summer of 2022 with the same buddy my reputation was restored–we fooled a couple of dozen brown trout, including a leviathan of 18-inches, in addition to a surprisingly good number of smaller rainbows.

Big Brownie Certifies Grape Creek Comeback

Later that fall I returned and found the rainbows outnumbering the brownies on the same stretch.   It started me wondering what was up. Was this natural recovery and reproduction by those rainbows or had some fish escaped from DeWeese Reservoir miles upstream or migrated from the Arkansas River below? Maybe some stocking going on, although these rainbows didn’t have the bland colors and frayed fins common with hatchery trout.

Now it’s fast forward to 2023, and I am embarking on my first trip of the year to Grape Creek, a pre-birthday celebration as I turn three-quarters of a century old tomorrow!  The weather is perfect as is the water level which has been a steady 23 cfs the past week.  I have bushwhacked down into the canyon several miles below the lake. 

Into The Wild Canyon

I am using my TFO 4# rod with a #16 Chubby Chernobyl in anticipation of a major hopper hatch with a #18 Tung Teaser to imitate the scads of mayfly nymphs I find scrambling around when I pick up a rock from the streambed. 

I strike out in the first pool, but the second and third produce some smaller rainbows and browns.  Not the hot action I expected.  I check the rocks again and find far more caddis cases and larva, so switch the dropper to a #18 beadhead sparkle caddis larva.  That proves to be the ticket. 

The Deadly Duo–Gold Chubby Chernobyl
and Beadhead Sparkle Caddis

Now the action is fast and furious.  In a run below a short stretch of rapids I fool a couple of muscular rainbows, one almost 14-inches. 

Rainbow On!

Next pool I get more rainbows and one 13-inch brownie, most on the dropper. 

That pattern continues as I net another dozen fish by lunch in addition to several long-distance releases. But surprisingly, the rainbows predominate as I catch four bows to every brown, a remarkable turnabout from the years before the floods.

I again mull over the mystery as wolf down my lunch and quaff my RC Cola elixir.  Natural reproduction?  DeWeese or Arkansas River migrants?  Stockers?  I soon head downstream to test the various hypothesis with some serious piscatorial research.  Now the hopper hatch is in full swing, and the Chubby Chernobyl excels as I work back upstream. 

Hopper Hatch = Feeding Frenzy

I come to a favorite pool created by a giant boulder about 10 feet below a shallow rapid. 

Big Boulder Honey Hole Pool And Rapids Above

I catch a rainbow and brown in the pool, then am surprised by a big rainbow that smashes the Chubby as it bounces down the rapids above.  As soon as he feels the sting of the hook, pandemonium breaks loose as the feisty finned creature goes shooting downstream right by me.  I do a graceful pirouette while issuing some choice expletives and then give chase.  But just as I catch up with the rascal, he shoots back upstream past the boulder and actually climbs through the rapids into the pool above, much like a wild salmon would do.  I reverse course and fortunately catch up when he decides to take a little rest.  I finally slide my net under a beautiful, strapping 15-inch rainbow! 

Rambunctious Rainbow

In the next pool downstream, I coax a 14-inch neon rainbow to strike as well as a respectable 13-inch brownie.  For the next couple of hours I fool two or three trout in every pool or decent run.  Overall for the day, I catch and release over three dozen fish with a 4:1 ratio of rainbows vs. brooks—almost just the opposite of the pattern before the floods.  What gives??  The bows look and act wild with freckles all over their faces, sleek, perfect streamlined bodies, and plenty of spunk. 

Several weeks later I navigate the rough, narrow 4wd road down to the creek at Bear Gulch, one of the few public access points.

The creek here flows through a large spectacular Bureau of Land Management wilderness study area.

I saunter up the stunning canyon, taking time to enjoy the abundant wildflowers, butterflies, and groves of giant cottonwoods along the creek.

I have another excellent day catching and releasing a couple of dozen fish. The rainbow/ brown split is about 50:50 compared to my past forays when the browns outnumbered the rainbows nearly 10:1 in this stretch. Most of the fish measure 10-14 inches, although I see a few larger finning in the depths of some deep pools.

Rainbow Pool

Now I am really flummoxed.  So I make a mental note to contact the Salida office of Colorado Parks and Wildlife (CPW) to see what they think is behind the rainbow resurgence up and down Grape Creek. 

When I called the next week I am lucky to connect with Alex Townsend, the helpful, knowledgeable aquatic biologist for the Arkansas River region, and he gave me the real skinny.  Rainbows, a variety of which had been stocked throughout the creek since the late 1980s, were virtually wiped out by the floods of 2019.  He tells me the brown trout seem to persist well in this system, bounce back better with natural reproduction, and are already showing some population growth, albeit slow.  However, the flooding gave him a chance to stock a new whirling disease-resistant strain of rainbow trout that is a cross between a Hofer from Germany, that is naturally resistant, with rainbow from the Gunnison River.  The Gunnison rainbows seem to have some natural resistance, are strong, wild fish, and have shown reproductive success.  He hoped that stocking these rainbows would give them a head start over the browns that seem to do well on their own.  He added that because the browns and rainbows have a somewhat different forage base and habitat, while there may be some competition, they don’t fully overlap.  Also, they do not use the same reproductive habitat during the same time of the year—browns spawn in the fall and rainbows in the spring.  My own experience this year and in the past supports Townsend’s point—I have caught many rainbows in faster, shallower water than browns which seem to favor deeper pools and slower runs.

CPW began stocking the hybrid rainbows from the Mt. Shavano Fish Hatchery near Salida in 2021 to the tune of 15,000 per year in 7-8 locations from the confluence of Grape Creek with the Arkansas near Canon City up to below DeWeese Reservoir.  He added that the stocked fish were about 2”-3” in size with an annual growth rate of about three inches although this is highly dependent on habitat and forage. Some fish will grow faster and some slower, he explained.  (The 15-incher I caught must have been feasting on those new steroid-infused hopper flies you can get at Ark Anglers.)  Townsend noted that next year he will be evaluating the population through electrofishing to determine if natural reproduction is occurring.

After hearing this explanation from Alex, I felt a bit like the inimitable Mr. Watson having just been educated by a piscatorial Sherlock Holmes, Townsend having provided a cogent explanation of the curious case of the resurgent rainbows. Quite elementary my dear Mr. Watson!!  It also gave me an even greater appreciation of the fine, hard-working folk at CPW like Alex.  Kudos to them for protecting and enhancing our rivers and streams.  They have created and maintained a wonderful fishery in Grape Creek with a vibrant mix of rainbows and browns. With climate change, habitat loss, and myriad other pressures our waters face, I am more thankful than ever for their efforts.  If you have some spare time, Alex and his CPW colleagues are periodically looking for volunteers to assist in their important projects—give them a ring at 719-539-5520.
