Diamond Valley Groundwater Management Plan

1.45pm – 2.45pm PDT, 16 April 2026 ‐ 1 hour

Education Session

Located in Eureka County, Diamond Valley is an agricultural area known for producing high-quality alfalfa and hay. Due to over-appropriation and over-pumping, the Diamond Valley Hydrographic Basin became the first Critical Management Area (CMA) in Nevada in August 2015, which started a 10-year timeline for water users in the basin to either develop and adopt a groundwater management plan (GMP) or, at the end of the 10-years, regulate groundwater withdrawals by priority (where only senior in time water rights could be used). A GMP was developed by the local water rights holders and approved by the State Engineer and upheld by the NV Supreme Court. This session will provide an overview of the GMP and provide perspectives on the development and implementation processes of the GMP.
