This site provides access to historic stream, rainfall, and evaporation data that VCWPD has in electronic format.

Welcome to the new VCWPD Hydrologic Data Server (Hydrodata).  This site provides the same data as the old WISKI Web Server in an easier to use interface.  This page provides rain, stream, and evaporation data from the District's official gages in Ventura County, as well as other available data used in District planning studies.

Due to the complexity of the website and datasets, we STRONGLY urge you to read our file explaining how to download data from this website and any associated caveats by clicking on: Hydrodata Web Questions. Please read the file before you contact us with any questions regarding this site or our data sets.

For certified data or non-standard data not available on this website, please send a data request to the Hydrology Section as outlined in Hydrodata Web Questions document.

Official and Preliminary data are available by water year clicking on the station name and by selecting the water year and format selectors for each dataset. Compiled official datasets and reports are available from the 'Official Reports and Datasets Published for this station' drop-down menus.
