The Southwest is the most surprising fishing region in America. In a landscape defined by desert mesas, saguaro cactus, and slot canyons, you might not expect to find world-class fishing -- but that is exactly what Arizona, New Mexico, and Nevada deliver. The region's reservoirs, fed by the Colorado River and Rio Grande systems, create fertile oases in the desert that grow fish to impressive sizes. Lake Mead, Lake Powell, Lake Havasu, and Roosevelt Lake are just the headliners of a diverse portfolio of warm-water and cold-water fisheries scattered across three states and multiple climate zones.
What makes the Southwest unique is the juxtaposition of desert bass fishing and mountain trout fishing within a short drive. You can chase striped bass on Lake Mead with the skyline of Las Vegas in the background, then drive four hours north to fish for wild trout on a freestone stream in the mountains of northern New Mexico. Arizona's White Mountains and New Mexico's Sangre de Cristo Range harbor cold-water streams and lakes that support rainbow, brown, and cutthroat trout populations. The Gila River drainage in New Mexico holds the rare Gila trout, one of the most geographically restricted salmonids in the world.
The warm-water fisheries of the Southwest benefit enormously from the region's long growing season and abundant sunshine. Largemouth bass reach trophy sizes in desert reservoirs, and striped bass in the Colorado River impoundments can exceed 40 pounds. Catfish are abundant in every warm river and reservoir, with flatheads and channel cats reaching impressive proportions in waters like the Salt River, Verde River, and Rio Grande. The lack of harsh winters means year-round fishing opportunity, though summer heat makes early morning and late evening the only practical fishing windows from June through September.
Desert reservoirs grow big bass thanks to long growing seasons and warm water. Roosevelt Lake, Saguaro Lake, and Elephant Butte in New Mexico all produce quality largemouth. Arizona's urban lakes also offer accessible bass fishing.
The Colorado River impoundments (Mead, Mohave, Havasu, Powell) hold enormous populations of landlocked stripers. Fish regularly exceed 20 pounds, and the boil-fishing when stripers chase shad on the surface is a spectacle.
Found in mountain lakes and streams at elevation in Arizona and New Mexico, plus in the tailwaters below major dams. Lee's Ferry on the Colorado River is one of the most famous trout fisheries in the world.
Channel and flathead catfish thrive in the warm rivers and reservoirs throughout the Southwest. The Salt River, Rio Grande, and Colorado River all produce quality catfish. Summer night fishing for big flatheads is a regional tradition.
Growing fishery in the Southwest, particularly on Lake Havasu, Lake Powell, and Bartlett Lake. The clear water and rocky structure of these desert reservoirs create ideal smallmouth habitat.
Abundant in many Southwest reservoirs, especially Roosevelt Lake, San Carlos Lake, and various New Mexico impoundments. The spring crappie spawn provides family-friendly fishing that is easy to access and consistently productive.
The largest reservoir in America (by capacity), straddling the Arizona-Nevada border behind Hoover Dam. Outstanding striped bass fishing with fish exceeding 30 pounds. Also holds largemouth bass, catfish, and rainbow trout near the dam. Dramatic desert canyon scenery.
A 15-mile stretch of the Colorado River below Glen Canyon Dam in Arizona. One of the most famous trout fisheries in the world, with rainbow trout averaging 16 inches in a stunning red-rock canyon. Year-round wade fishing with consistent cold-water releases.
A 186-mile reservoir on the Arizona-Utah border with 1,960 miles of shoreline. Excellent smallmouth and largemouth bass in the canyons, plus trophy striped bass and walleye. The slot-canyon arms provide uniquely scenic fishing anywhere in the country.
A Colorado River impoundment on the Arizona-California border famous for its bass tournaments. Excellent largemouth, smallmouth, and striped bass fishing in clear, rocky habitat. Also a prime destination for redear sunfish and channel catfish.
Arizona's largest lake, located in the Tonto National Forest. Outstanding largemouth and smallmouth bass fishing with less pressure than the metro-area lakes. Also holds crappie, catfish, and carp in a desert-mountain setting.
A premier tailwater below Navajo Dam in northern New Mexico. Blue-ribbon trout water with rainbow and brown trout averaging 16-20 inches. The Quality Waters section is restricted to artificial flies and lures, producing trophy fish in a high-desert canyon.
New Mexico's largest reservoir on the Rio Grande. Good largemouth and smallmouth bass, white bass, catfish, and walleye. The warm water and long growing season produce healthy fish. Also known for excellent crappie fishing in the spring.
Winter fishing is comfortable in the low-desert reservoirs. Bass fishing is slow but catchable on jerkbaits and blade baits. Trout fishing at Lee's Ferry and the San Juan River is productive year-round, with midge hatches on sunny afternoons. Stripers on Mead are in deep winter patterns.
Pre-spawn bass activity begins on lower-elevation reservoirs as water temperatures climb through the 50s. Crappie start staging near spawning flats. Trout fishing on tailwaters improves with lengthening days and more consistent hatches.
Bass fishing turns on across the Southwest. Pre-spawn largemouth move shallow on Roosevelt, Saguaro, and Havasu. This is the best month for big bass in Arizona's desert reservoirs. Striper fishing improves on Lake Mead as bait moves to the shallows.
Peak spring fishing. Bass spawn is underway on most reservoirs. Crappie are in the shallows. Striped bass begin their spring blitz on threadfin shad at Lake Mead and Mohave. Trout fishing is excellent at elevation as mountain lakes begin to thaw.
Outstanding fishing before summer heat sets in. Bass are post-spawn and feeding. Topwater action is excellent at dawn. Striper boils become frequent on Lake Mead. Mountain trout fishing in the White Mountains and Sangre de Cristos is at its best.
Summer heat arrives in the desert. Fish dawn and dusk only on low-elevation waters. Striper fishing can be excellent during early morning boils. Mountain lakes and streams at elevation offer comfortable fishing conditions. Night fishing for catfish is outstanding on desert rivers.
The hottest month. Monsoon storms begin in the latter half, providing brief windows of cooled water and increased fish activity. Mountain fishing is the best option. Desert reservoir fishing is strictly a dawn affair. Lee's Ferry and the San Juan fish well regardless of heat.
Monsoon season is in full swing with afternoon thunderstorms across the region. These storms cool the water and activate fish -- some of the best summer fishing happens in the window immediately after a monsoon passes. Mountain streams and lakes remain comfortable.
The fall transition begins. Water temperatures drop and bass fishing improves significantly. Striper boils return in earnest on the Colorado River reservoirs. Mountain trout fishing is excellent with fall hatches. One of the most pleasant months to fish in the Southwest.
Excellent fishing across the region. Comfortable temperatures, active fish, and beautiful weather make October the best month in the Southwest. Bass are feeding up for winter. Stripers are schooling and chasing bait. Brown trout begin their fall spawn on mountain streams.
Late fall produces quality fishing with few crowds. Bass fishing remains strong on reaction baits as water cools. Trout fishing on tailwaters is excellent with BWO and midge hatches. Catfish fishing slows. The weather is ideal for long days on the water.
Winter fishing begins but remains comfortable on low-desert waters. Bass slow down but are catchable on finesse tactics. Lee's Ferry and San Juan River trout fishing is uncrowded and productive. Striper fishing on Lake Mead can be excellent when fish school on bait in the backs of coves.
The Southwest has an arid to semi-arid climate with extreme heat in summer (110+ degrees in the desert) and mild winters (50-70 degrees at lower elevations). Mountain areas are cooler with genuine winters including snow. The monsoon season (July-September) brings sudden, intense thunderstorms that can dramatically affect water conditions, creating muddy inflows and flash-flood risks in canyon waters. Low humidity and intense UV at elevation require sun protection and hydration. Water levels in major reservoirs fluctuate with drought cycles and water management decisions.
