California Statewide Groundwater Elevation Monitoring (CASGEM)(SBX7 6)
The 2009 legislative package requires local agencies to monitor the elevation of their groundwater basins to help better manage the resource during both normal water years and drought conditions.
Local agencies can determine how to monitor groundwater elevations that demonstrate seasonal and long-term trends in groundwater elevations in their basin/subbasin(s) The Department of Water Resources (DWR) is required to assist local monitoring agencies with regulatory compliance.
ACWA and DWR are sponsoring a series of interactive workshops on the California Statewide Groundwater Elevation Monitoring (CASGEM). Information on the workshops is available here.
How will it affect California water utilities?
- Local agencies will be required to monitor the elevation of their groundwater basins and report the information to DWR.
- Local agencies can apply voluntarily to DWR to be the local groundwater monitoring entity that is responsible for monitoring and reporting the results to DWR.
- If no local agency volunteers to monitor groundwater elevations, DWR will assume responsibility for monitoring and the local agencies and county will not be eligible for State water grants or loans.
- If a basin is not currently monitored, DWR will work with the well owners in the area to determine interest in groundwater monitoring and facilitate creation of a plan or association to monitor groundwater elevation in those basins.
What are the compliance deadlines for the legislation?
- Certain types of agencies wishing to assume groundwater monitoring functions in accordance with the legislation must notify DWR, in writing, by January 1, 2011.
- Monitoring entities must begin monitoring and reporting groundwater elevations and DWR must begin indentifying the extent of this monitoring within each basin and subbasin on or before January 1, 2012.
- DWR must conduct an investigation of the state’s groundwater basins and report its findings to the Governor and the Legislature not later than January 1, 2012. Subsequent reports must be submitted in years ending with 5 or 0.
ACWA’s Implementation Activities
A small workgroup has been established in consultation with ACWA’s Groundwater Committee to work closely with DWR to develop a strategy/action plan (using to the fullest extent possible existing local programs) for meeting the requirements of the legislation and to satisfy the needs of all parties.
ACWA staff welcomes your input on the development of the groundwater monitoring program. If you have comments, suggestions or questions, please contact Danielle Blacet (e-mail), ACWA regulatory advocate.
