Welcome to Tres Rios!

​The Tres Rios Environmental Restoration project involves the rehabilitation of nearly 700 acres in and around the Salt River, restoring a vital wetland and riparian habitat.  The project creates a mutual relationship between the renewed wetlands and the nearby wastewater treatment plant. 

The lush and scenic Tres Rios is now home to more than 150 different species of birds and animals like muskrats, raccoons, skunks, coyotes, bobcats, and beavers. The beautiful cottonwood groves, willows, mesquites, and other desert shrub around the reed-lined ponds and along the trail attract many migratory and wintering songbirds. By bringing the Salt River back to the condition it was in during the early 1800s, this project is repairing a natural habitat. 

The reclaimed water from the wastewater treatment plant is pumped over to the wetlands, and the plants and animals take what they need before it is discharged back into the river.
