Tres Rios Wetlands Project

Welcome

The Tres Rios Environmental Restoration project involves the rehabilitation of nearly 500 acres in the Salt River bottom, 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, tamarisk and other desert shrub around the reed-lined ponds and along the trail attract many migratory and wintering songbirds.

By bringing the wetlands back to the condition they were in the early 1800s, this project is repairing a natural habitat. The reclaimed water from the 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.

The Overbank Wetlands Site is located west of 91st Avenue and is accessible by permit only which can be obtained by emailing Heather Finden. Please include in your email your postal mailing address and phone number and allow five to seven business days to receive your permit.

The Tres Rios Hayfield Wetlands Site, east of 91st Avenue, is permanently closed to the public. For general information about Tres Rios, call (602) 495-7477.
