The mission of the District’s Water Resources Monitoring program is to provide quality-assured water data for use in research, planning, public safety, recreation, and education. The District is committed to documenting our hydrologic conditions for present and future stewards of the unique water resources in our community.
The data sources below are intended for general use. Use the maps for browsing and the inventories for choosing stations based on your needs. The time-series data are presented in Microsoft Excel 97-2003 format. If you can’t open these files, you can download a free Excel viewer. If you need large data sets that include many stations, we can provide, by request, a variety of formats that could reduce your “data-mining” efforts.
Sometimes hydrographers will estimate missing values or make observations about how the data was derived. In these sets you will see a column of quality codes in addition to the time-series data. These codes provide you with background information on data reliability. You can access a list of codes and their definitions.
