Basin Boundary Adjustments
Department of Water Resources Boundary Modifications
The Sustainable Groundwater Management Act (SGMA) established a
process for
local agencies to request that the Department of Water
Resources (DWR) revise the boundaries of existing groundwater
basins or subbasins, including the establishment of a new
subbasin. The
Basin Boundary Emergency Regulation was developed through an
extensive
stakeholder outreach process and was adopted on October 21,
2015. The provisions of the emergency regulation go into effect
on November 16, 2015.

Groundwater Sustainability Agency (GSA) of Tehama County -
Initial Notification of Potential Basin Boundary Modification
Request
The proposed basin boundary modification is a jurisdictional
modification involving a consolidation of the portions of the
Colusa (5-21.52) subbasin located within Tehama County into the
portion of the Corning (5-21.51) subbasin located within the
Tehama County. This 1,300 acre area with 10 individual
landowners would get better representation by their local
elected officials on the Flood Control and Water Conservation
District Board of Directors, then to be grouped into the 918,380
acre Colusa subbasin that spans four counties. The Tehama County
Flood Control and Water Conservation District became the
exclusive Groundwater Sustainability Agency for the portions of
the Corning and Colusa subbasins located within Tehama County on
February 11, 2016.
