Welcome to the home of DEH’s Water Quality Program!
The Denver Department of Environmental Health (DEH) has been monitoring the quality of water in Denver’s lakes and streams for over 45 years. Over that time, the program has grown to include many other important facets of water quality. You can learn more about what we do by exploring the topics below. Follow us on Facebook for regular water quality updates and tips on safely recreating in Denver’s urban waters.
Please contact us if you notice any unusual conditions in any of the lakes and streams in Denver by calling 3-1-1 (720-913-1311) or by visiting Denver 311 online. We’d also like to hear from you if you have questions or concerns about water quality.
