    Pima County Natural Resources, Parks & Recreation will close Agua Caliente Park, 12325 E. Roger Road, beginning Aug. 19 for an extensive restoration of Pond 1. The purpose of the pond restoration is to conserve water by minimizing seepage from the pond and to improve habitat by deepening the pond and adding additional features. 

    The park closure, which will include closure of the Ranch House Visitor Center and Art Gallery, is expected to last several months.

    Staff have been slowly draining the main pond in order to prepare for the construction phase of the pond restoration project. Well water is no longer being pumped into Pond 1 and the remaining water from Pond 1 has been gradually siphoned into Pond 2. 

    The first stage of the restoration project involved removing select palm trees and invasive cattails, which will help restore the historic view of the pond and allow native species at the park to thrive in a healthier environment. 

    In this next phase, workers will be excavating the pond to deepen it and install a polymer-amended soil lining to the bottom and sides of the pond to reduce water loss. This phase will also include installation of a wildlife island and replacement of the bridge to the current island. 

    The restoration of Pond 1 will help ensure that it remains viable and a historic feature of the park for future generations to enjoy, said Karen Simms, NRPR Natural Resources Division Manager. 
    More information on the Pond 1 restoration may be found on the Agua Caliente Park website. During the time the park is closed, dog walkers who enjoy using the park can visit McDonald Park at 4100 N. Harrison Road.  

    The 101-acre park features an intermittent warm spring and ponds that are home to an exceptionally rich mix of plants and animals. Water conservation is the driving force behind the multi-stage process to restore the pond and address its long-term sustainability. Seepage from the pond’s bottom has caused significant and recurring water loss, and groundwater from the well is being continually pumped to keep the pond full. The pond is too shallow as the result of erosion and sediment build-up, which has contributed to the spread of invasive cattails.
