Main Pond (Pond 1) Restoration Update

     The restoration of the Main Pond (Pond 1) at Agua Caliente Park should begin this Spring (early March 2019). The current state is not sustainable. Pima County is pumping well water in amounts that vary seasonally from 60,000 to 100,000 gallons a day.

     The pond will mostly retain its current look with vegetation around the edges but cleaned out in the middle. The current depth is minimal with sediment that has accumulated over the years. The new depth will be deeper and variable to accommodate various waterfowl requirements. A bridge to the island similar to one that used to be there is also planned.

     Greater visibility of the pond surface will result from the removal of selected palms and cattails. These changes will improve wildlife habitat and provide more open water for migrating waterfowl. The historic character of this Tucson treasure will be restored.

     The restoration should begin early March 2019 by stopping the pumping of water into the pond. It will take several months to dry the pond. During this process, fish and other aquatic wildlife will be removed or relocated. Once drained, dredging will remove the sediment and place it near Pond 3 to dry. During the heavy equipment portion of this process, the Park will be closed for 4-6 weeks. Timing and duration will depend on Monson activity and should happen over the summer months. Once cleaned and contoured, a polymer product will be used to seal the pond by binding to the soil to prevent any water seepage. The edges will not be sealed to allow some seepage for landscaping around the pond edge. Assuming no changes to the projected timetable, the restoration should be complete in the Fall of 2019.

       Pima County will place information signs near the main pond with updates and FOAC will put information here and on our Facebook page. All the information panels (Trouble in Paradise, Concept Plan, Water Conservation, and Construction Plan) provide in-depth background of the current situation and are available to view on the Pima County website at the below link.

        Agua Caliente Park is on the National 
                Register of Historic Places!!

     On July 9, 2009, Agua Caliente Ranch Historic Landscape was entered into the National Register of Historic Places.  This is great news for the Park and should help preserve it for many generations to come.  The National Registry plaque is located to the right of the main entrance into the ranch house. 

Friends of Agua Caliente, Inc.

On a late night in October 1993, the Friends of Agua Caliente, Inc. (FOAC) was formed in an effort to save a historic site in the Tanque Verde Valley.  The organization was successful in saving three of the park's original five buildings.

FOAC has been formally recognized twice by the Tucson-Pima County Historical Commission for its involvement in the preservation of existing buildings and saving the pond site.  We were instrumental in securing a Heritage Fund Grant for the renovation of the Bunkhouse.  On Saturday, August 23rd, 1997, the newly renovated Historic Bunkhouse was officially opened to the public.  FOAC has since worked with the county on paved walking trails and signage at the park.  The Ranch House and Caretaker's Cottage renovations are complete.  The Ranch House opened to the public on April 17th, 2004.  Ranch House hours are 8 am to 4 pm (closed 12-1 pm) and is decorated with period furniture and a rotating art exhibit (see events link).

Although this grassroots organization remains small, the conviction of "The Friends" remains intact.  Today, FOAC is working to preserve the contemplative nature of this "oasis in the desert" along with its natural Sonoran desert plant and wildlife habitats.

The Friends of Agua Caliente, Inc., is a 501 (c) (3) non-profit corporation.  Donations to FOAC are tax deductible to the fullest extend allowed by law.  

Help us preserve this beautiful oasis in the desert.  Select Membership for more information and to see how you can make a difference in our own backyard!

Respect for Agua Caliente Park

Please respect the "off-limits" areas of Agua Caliente Park.  They are "off-limits" in order to protect the delicate nature of our natural water source and the beauty of the Park.  Off-limits areas include: The area where the spring comes out of the ground; the west side of Pond One; and several other "open" areas that provide shelter for our abundant wildlife.  If you see someone in those areas, please ask them to respect the "off-limits" or advise one of the Agua Caliente Park employees.  We appreciate your support.
