Household Water Supply Shortage Reporting System
California Household Water Shortage Data

In California water systems with fewer than 15 household connections, including individual household wells or water supplies, are regulated at the county level. Counties vary in their practices, but rarely do counties collect data regularly from these very small and individual, household water supplies. Even where data is collected it is entirely voluntary.

As the drought developed, local and state agencies started receiving anecdotal reports of household water shortages. At the time there was no means to record or track these reports. The Governor’s Drought Task Force created a Less than 15 Connections Work Group (Work Group) in early 2014. This cross-agency Work Group agreed that we needed an easily accessed system to get a more systematic understanding of which parts of the state had households at risk, and improve cross-agency response and coordination. The Work Group created a Google Form to receive ongoing reports of outages from local, state, federal and non-governmental organizations. A google form was created to record information submitted directly to the State. At the same time several counties developed their own tracking mechanism. The data from these counties is manually entered into the State database.

To improve and streamline data collection and reporting the Department of Water Resources has created a new integrated data system. The State has begun transitioning to the new system. The first step was to transfer the google form data into the new data system. This has been completed and the following figures were produced using the new system.

A cross-agency team, led by DWR, will work with counties to transition data submission to the new system. During this transition household water shortage counts by week may fluctuate due to the transition and not because actual counts have changed.

All Household Water Shortages Reported to the State,
by County
This table represents cumulative reports of household water shortages by county reported to the State since January, 2014 through February 07, 2017. Reports are received from multiple sources and there are occasional duplicate entries for the same household; duplicate reports have been identified and removed from the total counts manually and there may be some error in removal if the entries are not easily matched. There are agricultural and livestock wells or surface water shortages for non-household use reported through the form, but these are not included in household shortage counts. Missing information or no data for a given county does not necessarily mean that there are no household water shortages in the county only that none have been reported to the State.
Data Fields:

Reported Outages: these reports reflect households with active outages and water supply problems from a dry well, stream, creek or other surface water supply.

Verified Active Outages: these are known households without water from a dry well or an unavailable stream, creek or other surface water supply that have been supplied by and verified by an Operational Area to OES.

Resolved/Interim Solutions Obtained: these columns include the best available information about a report’s status as it is reported to state agencies. Solutions obtained are determined by the county, and there may be more resolved outages that are not captured in this data set. Currently only eleven counties report interim and/or permanent resolution.

Cumulative Household Water Supply Shortages
Reported to the State
(as of 02/07/2017)
This map represents cumulative reports of household water supply shortages by county reported to the State since July 2014 through February 07, 2017. The numbers represent the total number of households reporting a dry well, creek, stream, surface or other household water supply shortages. Cumulative shortage reports include active outages, active water supply problems, resolved outages, and outages where interim solutions have been implemented. Currently only eleven counties report interim and/or permanently resolved outages. Water supply shortages for agriculture, livestock, or other non-household uses are not included in these counts. Missing information or no data for a given county does not necessarily mean that there are no household water shortages in the county only that none have been reported to the State.

Cumulative Household Water Supply Shortages
Reported to the State at the End of Each Month
(as of 01/31/2017)
This bar chart represents the number of household water shortages in the state database each month. The numbers are cumulative, meaning that a report submitted in July 2014 is also part of the count for each subsequent month. The month the state received the report does not necessarily reflect when the shortage began. The numbers represent the total number of households reporting a dry well, creek, stream, surface or other household water supply shortages. Cumulative reports include active outages, active water supply problems, resolved outages, and outages where interim solutions have been implemented. Currently only eleven counties report interim and/or permanent resolution. Water supply shortages for agriculture, livestock, or other non-household uses are not included in these counts. Missing information or no data for a given county does not necessarily mean that there are no household water shortages in the county only that none have been reported to the State.
