Riparian Preserve at Water Ranch | Gilbert

The Riparian Preserve at Water Ranch in Gilbert, Arizona, is a unique 110-acre urban nature preserve and environmental education center designed to blend water conservation, wildlife habitat restoration, recreational amenities, and public engagement. Established in 1999, it is recognized for its innovative approach to sustainable water management through the use of treated wastewater and its role as a critical habitat for native plants and wildlife in the Sonoran Desert region.

Natural and Environmental Features

At the heart of the preserve are seven large recharge basins filled with treated effluent water sourced from the local water treatment plant. This water is allowed to slowly percolate through the ground, replenishing the local aquifer and helping sustain groundwater levels in the region. One of these basins is specially designed to mimic a natural ephemeral desert stream, providing a dynamic environment that fluctuates seasonally, which supports diverse plant and animal life.

The preserve features a variety of native vegetation zones that recreate Arizona’s riparian ecosystems, including marshlands, wetlands, cottonwood-willow forests, and upland desert areas. This rich plant diversity creates habitat for a wide array of species, making the preserve a prime location for wildlife observation. Birdwatchers can spot nearly 300 species of birds documented at the preserve, including waterfowl, raptors, songbirds, and migratory species. Other wildlife includes amphibians, reptiles, mammals, insects, and various aquatic creatures that thrive in the managed wetlands and ponds.

Trails and Recreation

The Riparian Preserve offers over 4.5 miles of well-maintained trails that meander through different habitat areas and around the ponds and recharge basins. These trails are accessible and suitable for walking, jogging, birdwatching, and nature photography. Some trail segments connect to the broader Gilbert Trail System, providing extended routes for longer excursions.

A key recreational feature is the stocked urban fishing lake, managed in cooperation with the Arizona Game and Fish Department. The lake supports species like largemouth bass, catfish, and sunfish, attracting anglers of all ages. Fishing requires a valid Arizona fishing license, and the setting offers a peaceful outdoor experience surrounded by native vegetation.

The preserve also includes a floating boardwalk that crosses part of the northern pond, allowing visitors close-up views of aquatic plants, fish, and waterfowl. This boardwalk enhances accessibility and provides educational opportunities through interpretive signage about the aquatic ecosystem.

Educational and Cultural Components

The preserve is not just a natural retreat but also an educational hub. It features the Gilbert Rotary Centennial Observatory, operated by the East Valley Astronomy Club. The observatory houses a solar telescope for daytime viewing and a 16-inch Meade telescope for nighttime stargazing. Public star parties are held regularly, offering visitors an opportunity to explore astronomy with expert guidance.

An Ethnobotanical Garden within the preserve showcases native plants and explains their traditional uses by indigenous peoples, providing cultural and historical context. Another engaging feature is the Dino Dig Site, a hands-on paleontology exhibit where children and families can participate in simulated fossil excavations, fostering curiosity about natural history.

The preserve also promotes mental health and wellness through the Hope Walk, a dedicated path featuring inspirational messages and mental health tips designed to encourage reflection and positivity.
