New Mexico Fishing Guides
New Mexico is the San Juan. The tailwater below Navajo Dam produces more large rainbow trout per mile than any river in the Lower 48 except perhaps the Green in Utah. Add the Rio Grande headwaters for wild cutthroat, the Gila Wilderness for native Gila trout, and the Chama for a tailwater alternative, and New Mexico is a trophy-trout state most anglers overlook.
Top waters in New Mexico
San Juan River (below Navajo Dam)
Rainbow trout, brown trout
'Quality Waters' stretch is four miles of catch-and-release barbless flies-only water. 10,000-15,000 fish per mile. Midge fishing is the year-round constant — tiny flies on long tippet for 18-22 inch rainbows.
Rio Grande (Lower Gorge)
Rainbow trout, brown trout, cutthroat trout
Canyon fishery near Pilar. Rugged access — hike down from the rim or boat. Less pressure than the San Juan. Salmonfly hatch in mid-to-late June. Wild fish in wild country.
Chama River
Rainbow trout, brown trout
Tailwater below El Vado and Abiquiu dams. Wade-friendly, less crowded than the San Juan. Caddis and BWO hatches through the warm months.
Gila River headwaters
Gila trout
Hike-in wilderness fishery for the native Gila trout — one of only a few populations of this threatened species in existence. Small streams, careful handling required. A pilgrimage fishery.
New Mexico fishing by season
Spring
San Juan fishes well year-round; spring BWO hatches are excellent. Salmonflies on the Rio Grande in late May. Gila River headwaters open as snowmelt recedes. Pre-runoff clarity is optimal.
Summer
Midge hatches on the San Juan continue. Afternoon thunderstorms daily in the mountains. Gila Wilderness trips are best in June before summer heat. Jemez Mountains streams hold small wild cutthroat.
Fall
Peak San Juan season — cooler temps, brown trout pre-spawn, aspens in the San Juans. Rio Grande Gorge at its best. Gila Wilderness fishes well until snow closes access in November.
Winter
San Juan fishes all winter — midges don't care about air temperature. Winter nymphing is the meditative standard. Low angler counts, often crystal-clear water. Dress for 0°F at 6,000 feet.
The San Juan's Quality Waters section produces rainbow trout that grow to 24 inches on a diet of midges and scuds, in a river that stays at 44°F year-round. Few places in America offer consistent double-digit-fish days on trophy trout. The Gila River is the only place in the world you can catch Gila trout — a species almost lost to extinction and now holding in a handful of wilderness streams. New Mexico gives you both: guaranteed big-fish action and a genuine rarity.
The San Juan in January and February is the local's secret season. Water temps and insect activity don't change much from summer, but angler counts drop 70%. You can park where you want, fish the best runs without crowds, and nymph to pods of feeding 20-inch rainbows. Dress warm and expect the Quality Waters lot to have 10 cars instead of 100.
