The Davis Wastewater Treatment Plant treats water at the tertiary level which is completely compatible with the Wetlands environment. This high quality treated wastewater is reused in the Wetlands to support habitat, in turn benefiting wildlife and humans alike.
Water levels in the Wetlands are regulated seasonally. In March and April, the water levels are drawn down for the summer to expose seasonal benches and mudflats. This creates foraging habitat for shorebirds. Also, by keeping water off the benches, mosquitoes are discouraged. In the fall and winter months, increased stormwater flows are directed to the wetlands. The higher levels inundate the benches, creating shallow habitat for waterfowl and wading birds. The vast areas of open water provide plenty of habitat for wintering waterfowl to raft and avoid terrestrial predators.
The Wetlands environment is monitored continuously to ensure its quality. Water and soil are frequently tested for potentially harmful constituents such as heavy metals. You can help keep the Davis Wetlands healthy by making sure only clean rainwater goes into storm drains. More information about the city's Stormwater Management Plan can be found by clicking here.
