What is Groundwater Resources Management/SGMA?
GSPs are planning documents that define the actions required for managing a basin sustainably. A complete GSP includes a hydrogeological conceptual model (HCM) that establishes the current basin settings and conditions; an evaluation of SGMA’s six sustainability indicators (SGMA defines six undesirable results: chronic lowering of groundwater levels, reduction of groundwater storage, seawater intrusion, land subsidence, water quality degradation, and depletions of interconnected surface water); current and projection of water budget; a list of management actions and projects for achieving sustainability; and financial impacts and resources of the GSP implementation. In summary, a groundwater basin is managed sustainably when the amount of produced groundwater from aquifers is recharged naturally or artificially.
