Call the Jefferson County Sheriff’s Department at (303) 277-0211 if you believe the matter is an urgent water quality concern, for example something unusual in a ditch or waterway such as colored water, the appearance of a fuel slick or a suspicious material on the land that could wash into the storm drain system. If you notice something that is not urgent (it can wait until the next day), please call the Jefferson County Planning and Zoning Division (303.271.8700).
