Snowmelt and Stoneflies: New Mexico’s Fly Fishing Season Unfolds

Spring in the high country doesn’t arrive gently. It comes roaring down the mountains in a cold rush of snowmelt, swelling creeks, muddying runs, and reminding every angler that patience is just as important as presentation.

Right now, runoff is in full stride across Northern New Mexico, putting most streams out of shape. But as any seasoned fly fisherman knows, there are always a few bright spots if you know where to look. At the moment, the Cimarron and the Culebra are carrying the load—and carrying it well.

The Culebra is just beginning to rise with the start of irrigation season, and that added flow should only improve conditions through May and into June. The Cimarron, steady as ever, has been fishing well for the past month and is expected to hold strong through the upcoming stonefly hatch. We’ve been working waters at Ute Creek Ranch and the Cimarroncita, both producing nicely, with snowmelt combining with releases from Eagle Nest Lake to keep flows healthy. Access on the Culebra remains open, and for now, that’s good news for anglers willing to pick their water carefully.

We kicked off the season with the annual Superfly competition on the Conejos River—a tradition as unpredictable as the weather itself. Jon Harp once again put together a first-rate event, complete with the usual Conejos cocktail: wind, snow, and just enough sunshine to remind you why you came. The snowpack above Platoro looks solid this year, and with adequate reservoir releases expected, the Conejos should come into shape by mid-June—right on cue for the stonefly and green drake hatches.

Up north, the long-term work continues on the Rio Grande Cutthroat Restoration Project along the Rio Costilla in the Valle Vidal. Now in its second year of a planned 15-year effort, crews have treated the upper reaches of Comanche Creek and its tributaries, installing a fish barrier near the Little Costilla Peak trail. The goal is to restore pure-strain Rio Grande cutthroat trout to these waters. While work continues in the upper drainage this season, the Rio Costilla itself should remain fishable from July through September—offering both opportunity and a front-row seat to one of the region’s most important conservation efforts.

Elsewhere, the Rio Grande and the Red River are pushing toward peak flows and will likely stay high for some time. The Red, in particular, is a river to watch. Since the flash floods of 2007 knocked back its brown trout population, the canyon hasn’t quite returned to its former glory. Still, recent trips have shown encouraging signs—healthy insect life, solid gravel, and fish that appear to be rebounding. With a little cooperation from the weather, this could be the year it begins to turn the corner.

As for us, the season has already taken us far afield. Rita has been doing what she does best—chasing fish from the Bahamas to the Yucatán, and now up in Montana. She’ll be back in New Mexico by June 1, guiding through mid-August before heading north again to work the big water of the Kootenai, Yaak, and Clark Fork. Those rivers call for a different rhythm altogether—drift boats, long runs, and wide horizons.

I managed a trip down to Baja this winter, spending time along the Sea of Cortez. But like most seasons, it also included plenty of time closer to home—watching snow stack up and slipping out along the upper Rio Grande in search of northern pike when the itch got too strong.

That’s the way of it in this country. Seasons overlap, rivers rise and fall, and the calendar never quite tells the whole story.

If you time it right—and keep an eye on the water—there’s always a window.

We hope to see you out there somewhere between the runoff and the rise of the bugs.
