Pond 1What is happening to Pond 1 at Agua Caliente Park?

Lots of progress has been made with the Agua Caliente Pond 1 Restoration construction since it began on October 7. The pond excavation and grading work within the pond are nearly complete, the initial base coat of polymer liner has been applied, and the wildlife island has been constructed. The abutments for the bridge are under construction, and access improvements are underway on the shore.

Work remaining includes final grading and filling of pond; application of 2nd liner coat; completing bridge abutments; access improvements and landscaping. Bridge construction will be scheduled once the other elements are completed.

Pond 1 Construction OctoberThe park received nearly 1.5 inches of rain in the first November storm and more over Thanksgiving. These storms are causing delays in the remaining construction work.

The second photo was taken in October, the third photo is from early November showing progress being made on the pond.

Agua Caliente Park will remain closed during this phase of construction.

What about the spring?

The Agua Caliente spring continues to flow at the present time probably due to the large amount of winter precipitation this year, but appears to be decreasing. The spring flow is being diverted to Pond 2 or to native plant areas in the park.

Agua Caliente ParkAbout Agua Caliente

Agua Caliente, literally meaning hot water, is a unique 101-acre park that features a perennial warm spring and pond that is home to an exceptionally rich mix of plants and animals. Agua Caliente Park has a long and interesting history with evidence of human habitation dating back about 5,500 years. In 1873, a ranch and health resort was developed to promote the curative properties of the warm springs. In 1984 local businessman Roy P. Drachman donated over $200,000 toward the purchase of Agua Caliente Ranch and Pima County named the park in honor of this contribution. Roy P. Drachman Agua Caliente Park opened to the public on January 19, 1985.

Improvements have added the modern conveniences without eliminating the historical aspects of the park. On July 9, 2009 Agua Caliente Ranch Rural Historic Landscape was placed in the National Register of Historic Places.

The flow rate from the spring has varied over time reportedly as high as 500 gallons per minute to an unmeasurable seep in recent years. The sources and pathways for the water that now infrequently comes out of the natural spring head are not fully understood. Rainfall and snow on the Santa Catalina Mountains, shallow and deep rock stresses and fractures as well as significant heat generated hundreds of feet below the surface, all contribute to the complex and changing system. In recent years the pond has been maintained with water pumped from a well located on the property.

Visit the renovated 1870s Ranch House Visitor Center and Art Gallery, tour the park on one of the many naturalist led walks, or picnic in the shade of mature palm trees and native mesquite trees. Browse through the many bird-related items for sale in Tucson Audubon Society’s Nature Shop. Stroll the network of accessible paved and gravel trails with interpretive signs that explain the geology and history of the warm spring and the natural and human history of the site.
