Water Ranch: The Ponds That Bank Gilbert's Future
The Riparian Preserve is a water-recharge facility wearing the clothes of a nature park — 110 acres of ponds, trails and owls. How it works, and how to walk it in November.
Stand at the Riparian Preserve at Water Ranch on a November morning and the scene reads as pure nature park: ponds glittering with ducks, herons stalking the shallows, cottonwoods turning, trails busy with birders carrying scopes. The engineering underneath is the point. This landscape is a machine for putting water into the ground — Gilbert's treated wastewater, recharged through these ponds into the aquifer, banked against the desert's dry years.
The preserve occupies 110 acres at Greenfield and Guadalupe, adjacent to the Southeast Regional Library. Its seven recharge basins rotate through wet and dry cycles, spreading reclaimed water over prepared pond bottoms where it percolates down to storage. On the surface, the town and its partners — including the local Audubon chapter's stewardship — planted the ponds' edges with native habitat: mesquite bosques, wetlands, and the famous burrows along the paths where burrowing owls, the preserve's mascots, hold their ground and regard the photographers.
The bird list is the preserve's public fame: around 300 species recorded, a number that makes this suburban water facility a destination for birders across the Southwest. November through February is the peak: wintering waterfowl arrive in force, raptors work the ponds, and the dawn chorus at the overlooks draws a quiet crowd that Gilbert wisely counts among its tourist attractions.
For residents, the preserve is also daily infrastructure — the trail system for the neighborhoods around it, the field-trip destination for the town's schools, and the demonstration, visible from a library window, of how a desert town closes its water loop. Trails are open dawn to dusk; the fishing lake at the adjacent Water Ranch area is stocked under the state's community fishing program; dogs stay on leash, and the recharge basins' working areas ask visitors to keep to the paths.
Our outdoors desk will keep the preserve in rotation through the winter: bird arrivals, trail conditions, water operations in plain language. Gilbert's cleverest idea deserves a standing audience, and November is when it performs.
