The site is an interactive map of the United States that allows users to search or move around the map to find the USGS collection of maps for a specific area. Users may then view the maps in great detail and download them if desired. In 2008 the USGS abandoned traditional methods of surveying, revising, and updating topographic maps based on aerial photography and field checks.

If the Sacramento river is not in flood then any overflow runs into the Tule Canal , continues as Prospect Slough and finally enters the Sacramento River at Cache Slough . If the Sacramento is in flood, then the overflow from the settling basin is swept into the Yolo Bypass and Sacramento Bypass flood control system, emerging directly at Cache Slough . Water rights and flooding protection have been in dispute between Yolo and Lake Counties since
