Sweetwater Wetlands Updates:

Sweetwater Wetlands Water Levels
The scheduled and much-anticipated transition from the old Roger Road Wastewater Treatment Plant to a new, modern treatment facility is resulting in temporary reduced flow to the Sweetwater Wetlands. Because of the reduced flow, the water level in the Wetlands ponds will be lower. By mid-March 2014, water levels should rise as the Wetlands receives the new, higher quality water from the treatment facility.

New Parking Area
A new parking area across the street from the old parking lot is under construction and scheduled to open to the public in early 2014. The additional parking spaces (for cars and school buses) should reduce the need for parking along Sweetwater Drive, which will also be marked appropriately with necessary crosswalk markings.

New West Entrance to Sweetwater Wetlands
A new west entrance to the Sweetwater Wetlands is now open from the newly-paved bicycle path along the east bank of the Santa Cruz River. This amenity was designed and built by Pima County through funding for its "Loop" bicycle trail system. The entrance includes a bench, trash bin and bicycle racks. Please remember that bicycle riding and dogs are not allowed on the Sweetwater Wetlands property.

Access to the facility is sometimes affected by the Interstate 10 widening project managed by the Arizona Department of Transportation (ADOT).
