Basin Boundary Modification 2018
The Yolo Subbasin Groundwater Agency submitted a Basin Boundary Modification Request to DWR on September 14, 2018 and on November 29, 2018 DWR released the draft Basin Boundary Modification Results. The Basin Boundary Modification incorporated Reclamation Districts 150, 307, and 999 into the Yolo Subbasin (as shown in the map below).
This modification request results in a minor modification to the South American Subbasin western boundary, as it adjusts it from the line of the Sacramento River to the County line.
The new Yolo Subbasin as approved by DWR is highlighted below.
