    Members of the public can review a concept plan on the planned restoration of Pond 1 at Agua Caliente Park at an open house on Thursday, Nov. 8, 5-7:30 p.m., at Kirk-Bear Canyon Library, 8959 E. Tanque Verde Road.  

    Pima County Natural Resources, Parks & Recreation manages the park, a 101-acre facility that features a perennial warm spring and ponds that are home to an exceptionally rich mix of plants and animals. Water conservation is the focus of the multi-stage process to restore the pond and address its long-term sustainability.

    Staff from Pima County’s Regional Flood Control District, Office of Sustainability and Conservation, and NRPR will be on hand to discuss water conservation, concept plan design and schedule, protection of resources and the benefits of the project for the community. The public can view various displays in addition to the concept plan addressing these issues.

    Agua Caliente’s spring has not produced measurable flows of water since 2014 and has required continuous groundwater pumping 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. Seepage from the pond’s bottom has caused significant and recurring water loss.

    Beginning in summer 2019, the goal is to restore Pond 1 by:
    • Dredging the pond to increase depths.
    • Reducing water loss from the bottom with a polymer-amended soil lining.
    • Replanting cattails in containers and increase the water depth at the pond’s edge to control the spread of cattails.
