Welcome to the Colorado River Basin Streamgage Catalog. This catalog visualizes locations of streamgages and precipitation measurements around the Colorado River Basin states located the Southwest United States. The goal of this catalog is to provide information to stakeholders, increase effective management of resources, and help establish protocols for future data collection.
This map is interactive so you can scroll over each point and view metadata about the gage. You can use the filters on the bar to the right of the map to search for specific agencies, types of gages, and whether they are currently operating or inactive. To access the links associated with gages, click on "view data" and copy link from table that is shown.
This catalog is not an exhaustive list of all gages. Some private organizations were not able to share gages that they operate and tribal communities that may operate gages were not contacted to respect the privacy of their local government operations and information.
This is an on-going project, additional updates will be made to this map as new gages are obtained and cataloged. We are currently working on collecting and adding data for California.
