In 2015, Humboldt County received a planning grant from DWR for technical studies and planning which led to the submission in December 2016 of a Groundwater Sustainability Plan (GSP) Alternative, a streamlined version of a GSP. The GSP Alternative was disapproved by DWR in 2019 primarily because objective management criteria had not been established for 10 years; a quantitative estimate of sustainable yield was not developed; and the GSP Alternative did not quantify the impacts of groundwater use on surface water systems and determine at what point they are significant and unreasonable. As a result of the GSP Alternative being disapproved, formation of a Groundwater Sustainability Agency (GSA) was required and development of a full GSP was required by January 31, 2022.
