Sierra Valley Groundwater Basin Sustainability Plan
Description
The Sierra Valley Groundwater Management District (SVGMD) is the state-identified Groundwater Sustainability Agency for the Sierra Valley Groundwater Basin; as defined in California?s Sustainable Groundwater Management Act of 2014 and DWR?s Bulletin 118. As such; SVGMD is tasked with the preparation of a 20-year horizon Groundwater Sustainability Plan (GSP) for this medium-priority basin. This project will involve contracting with a qualified consultant/consulting firm to complete the Sierra Valley Groundwater Sustainability Plan prior to the legislated deadline of January 31; 2022.
CA DWR reports indicate declines in groundwater levels and artesian well production along the east and northeast side of the valley in addition to poor quality water in the west-central side of valley (boron; fluoride; arsenic; & sodium). SVGMD monitoring well reports show groundwater levels dropping in the Valley since the mid-1990s. Further; drought and climate change both indicate the need for a sustainable management plan.
Plan Components: Shall include; at minimum; state-mandated format and contents:
A description of the physical setting and characteristics of the aquifer system.
Historical date; groundwater levels; ground water quality; subsidence; groundwater-surface water interaction; a discussion of historical and projected water demands and supplies.
A map that details the area of the basin and boundaries.
A map identifying existing and potential recharge areas that substantially contribute to the recharge of the basin.
Measurable objectives; as well as interim milestones in increments of five years; to achieve the sustainability goal in the basin within 20 years.
A planning and implementing horizon.
The monitoring and management of groundwater levels; water quality; groundwater quality degradation; and inelastic land surface subsidence.
A summary of the type of monitoring.
The monitoring protocols.
A description of the consideration of other applicable local government plans and how the GSP may affect those plans.
This project supports all five UFR IRWM Goals.
