Arizona
Grand Canyon, and equally grand waters
Overview
Home to the Colorado River, the Grand Canyon, and countless slot canyons, Arizona is known for its scenery. Less known are the native and wild trout fisheries in the mountain ranges cutting across central Arizona. Fragile, unique populations of Gila and Apache trout—iconic features of the Southwest—persist in the face of climate change, wildfire, and historic drought. Lees Ferry, the dividing line between the Upper and Lower Colorado River Basins, provides some of the best wild trout fishing in the state. We are working to protect and recover the state’s unique native trout while supporting wild trout fisheries that are important to Arizona’s trout anglers.
Fish We're Protecting
Threats & Opportunities
The Gila trout is listed as threatened by the U.S. Fish and Wildlife Service; the agency proposed removing the Apache trout from the Endangered Species List, but more work remains to keep it on stable footing. Climate change is a real and immediate threat to Arizona’s trout streams. Small native trout populations in small streams are extremely susceptible to wildfires. Subpopulations have been wiped out. It is urgent that we work to recover and build these strongholds. Doing so will likely require a larger toolbox of strategies than what is utilized in many other states.
What We're Accomplishing
Restoring National Forests Impacted by Wildfires
The Thompson-Burro Meadow is a pivotal conservation area in Apache-Sitgreaves National Forest scarred by recent wildfires. Its streams feed the Phoenix Valley and Colorado River, and are home to the state’s native Apache trout. In recent years we have installed more than 200 in-stream log structures using repurposed slash from a nearby Forest Service thinning project to help slow water and reconnect the stream to its floodplain. Now, water remains in the system even during the hottest months of the year. We are monitoring groundwater levels and measuring how much water is flowing downstream.
Protecting and Enhancing Arizona’s Public Lands
We are continuing to advocate for greater protections on land adjacent to Grand Canyon National Park due to the toxic history of uranium mining in the region. With more than 500 abandoned mines scattered throughout the area, the recently designated Baaj Nwaavjo I’tah Kukveni Grand Canyon National Monument prohibits new mining claims while allowing other uses, such as timber harvesting, cattle grazing and outdoor recreation.
Partnering With the White Mountain Apache Tribe to Support Apache Trout Populations
We are partnering with the White Mountain Apache Tribe’s Game and Fish Department and the U.S. Fish and Wildlife Service to replace or remove 11 culverts on Paradise Creek and Deep Creek, streams that provide critical Apache trout habitat threatened by prolonged drought. These projects ensure Apache trout can access the best spawning habitat in the spring and seek refuge during the hottest times of the year.
Delisting Native Apache Trout From the Endangered Species Act
Apache trout are resilient, persisting through decades of threats long enough for the power of partnerships to help bring them back. Beginning in the 1950s, the White Mountain Apache Tribe took action to reverse the trout’s population declines. In the decades since, we have worked with them and a range of partners, including the San Carlos Apache Tribe, Arizona Game and Fish Department, Forest Service, and U.S. Fish and Wildlife Service, to restore Apache trout populations. This work led to removal of the fish from the Endangered Species list, making it the first and only sport fish ever to be delisted due to recovery.

Priority Waters
-
Salt River Basin
This is the only coldwater trout fishery in America that runs through a desert. Its headwaters originate in the White Mountains, home to genetically pure populations of Apache trout, Arizona’s state fish. Providing much of the water supply for Phoenix, the 200-mile Salt River flows through Tonto National Forest and is popular for tubing, wild horse viewing, and fishing. In a warmer Southwest, we need to protect each remaining coldwater stream, and the Salt River Basin provides a diversity of habitat that will provide trout habitat into the future.
-
Upper Gila River Basin
One of the longest rivers in the West, the Gila is a 649-mile tributary of the Colorado, renowned for its 280 species of bird habitat and native Gila trout. Rugged, remote streams in the Blue River tributary watershed present our best opportunity to create a Gila trout stronghold in Arizona. In the Pinaleno Mountains, two Gila trout populations are reproducing thanks to recovery efforts following a devastating wildfire.
-
Verde River Basin
One of Arizona’s last free-flowing rivers, the Verde River, runs 192 miles from its headwaters in Chino Valley to the confluence of the Salt River. More than 40 miles are designated Wild and Scenic. We are working to build connected strongholds for Gila trout in the watershed, including fishable populations. The basin is home to the endangered razorback sucker and Colorado pikeminnow.
-
Little Colorado River Basin
One of the largest tributaries to the Grand Canyon, the Little Colorado River runs for 45 miles across the plains of the Painted Desert in the Navajo Indian Reservation, eventually forming a narrow and 100-foot deep gorge near Cameron that offers stunning views on the way to the Grand Canyon itself. Rainbows, brown trout, and brook trout thrive in 15 wild trout streams. Small populations of Apache trout live in its headwaters.
