Visit this unique wastewater treatment facility with specially trained docents the first Saturday of each month. This constructed wetlands project utilizes treated wastewater and stormwater to create wildlife habitat. The 400-acre site was previously agricultural land and is now being returned to a managed native California wetlands ecosystem that includes oak riparian woodlands and native grasslands. Learn about the various biological processes that enhance water quality, the advantages of a native plant community and see hundreds of shorebirds in the peak of their southern migration. Birds that may be seen include: dowitchers, yellow legs, sandpipers, avocets, stilts, long-billed curlews, ibis, egrets, herons, yellow-headed blackbirds, a peregrine falcon and various hawks and waterfowl.

For warm weather bring a hat and sunscreen. For cold weather dress in layers. For all trips bring water, binoculars, spotting scopes and shoes that can get muddy.
