Kings Subbasin Coordination

Groundwater Sustainability Plan Coordination

CA DWR outlines the three options for developing and implementing Groundwater Sustainability Plan’s (GSPs) in a subbasin. According to the law, a GSP may:

  1. Be a single GSP developed and implemented by one GSA covering the entire subbasin OR
  2. Be a single GSP developed and implemented by multiple GSAs covering the entire subbasin OR
  3. Be multiple GSP’s developed and implemented by multiple GSAs under a formal coordination agreement covering the entire subbasin

The Kings Subbasin GSAs are moving forward with option 3, and as such will be entering a formal coordination agreement to achieve subbasin alignment towards sustainability.

A coordination agreement includes:

  • a description of a single point of contact for the basin
  • establishes procedures for resolving conflict
  • ensures multiple GSAs use the same data and methodologies for assumptions in the GSPs
  • describes a coordinated data management system
Kings Subbasin Initial Overdraft Responsibility

The seven Kings Subbasin agencies have agreed upon an initial overdraft amount for the Kings Subbasin of 122,000 acre feet (AF). The table below (click to enlarge) shows the agreed upon initial target overdraft amount for each GSA.

The McMullin Area GSA is responsible for 91,000 AF of the total subbasin amount. The GSA will work to correct the target overdraft amount by the SGMA sustainability deadline of 2040.
