These data are provisional and subject to change. If you have questions or concerns about the data you see, please contact us for clarification.

All data herein comes from the monitoring site(s) shown in the Overview, with the exception of Potential Evapotranspiration (called “ET” here for convenience). ET data is sourced from the California Irrigation Management Information System (CIMIS). The locations of the CIMIS site(s) closest to your monitoring site(s) are shown in the Overview.

Thanks for noticing something! Please send an email describing the error to our staff so we can investigate. Be sure to include a screenshot, a description that will help us find the error, and the dashboard URL.

This dashboard reports data received from sensors every 24 hours, which updates daily around 2pm PT. These systems are generally very reliable, but every so often, data does not transmit as expected. If data has not been received within the last 24 hours, a daily summary will not be shown on the Overview. However, historical data (data older than 24 hours) will always display on the individual tabs (e.g., “Groundwater”, “ET”, etc.). If you notice that data has not transmitted in more than 48 hours, please contact LWA.
