This project was authorized as a joint effort between the County and Cities of Atascadero, Arroyo Grande, Grover Beach, Morro Bay, Paso Robles, Pismo Beach, and San Luis Obispo.

Atascadero Groundwater Basin

The "Atascadero Area Subbasin", DWR Bulletin 118 Basin No. 3-004.11, was subdivided from the "Paso Robles Area Subbasin" (of the Salinas Valley Groundwater Basin) in 2016 based on information that showed the Rinconada Fault is a significant barrier to groundwater flow. The Paso Robles Formation makes up most of the water-bearing sediments for both subbasins and the lateral (outer) extents are primarily defined by the contact with the Monterey Shale (bedrock). The boundary between the Paso Robles Subbasin and the Atascadero Subbasin is defined by the Rinconada Fault.

In 2015, the State legislature approved a new groundwater management law known as the Sustainable Groundwater Management Act (SGMA). SGMA requires that high and medium priority basins comply with the new law. DWR designated the Atascadero Groundwater Basin as a high priority basin. The map below shows those areas subject to SGMA.

Los Osos Valley Groundwater Basin

The Los Osos Valley Groundwater Basin, DWR Bulletin 118 Basin No. 3-08, is bounded on the north by Park Ridge, on the south by Irish Hills, on the west by Morro Bay, and on the east by a drainage divide separating Los Osos Valley from San Luis Valley. The Los Osos Basin, as defined by DWR, is located in San Luis Obispo County and covers 6,990 acres (10.9 square miles).

In 2015, the State legislature approved a new groundwater management law known as the Sustainable Groundwater Management Act (SGMA). SGMA requires that high and medium priority basins comply with the new law, with certain exceptions for listed adjudicated basins. DWR categorized the Los Osos Valley Groundwater Basin as a high priority basin and designated the basin to be in a “condition of critical overdraft”. SGMA does not apply to the portion of the Los Osos basin that is at issue in the litigation (“adjudicated area”) provided that certain requirements are met by the Los Osos Basin Management Committee. However, there are “fringe areas” outside of the adjudicated area, but within the State-determined basin boundaries that must comply with the new groundwater management requirements. These “fringe areas” are referred to as the Eastern Valley Area and the Southern Beach Area. The maps below show both the adjudicated areas exempt from SGMA, and the fringe areas that are subject to SGMA.

San Luis Obispo Valley Groundwater Basin

The San Luis Obispo Valley Groundwater Basin, DWR Bulletin 118 Basin No. 3-09 is situated in the San Luis and Edna Valleys in central to southwest San Luis Obispo County. A rise in bedrock south of the San Luis Obispo Airport has created two separate subsurface drainage systems or subbasins (i.e., San Luis Valley and Edna Valley). The basin overlies an area of approximately 12,700 acres (19.9 square miles) and is part of the Central Coast Watershed. The Edna Valley Subbasin (approximately 4,700 acres) is entirely within unincorporated San Luis Obispo County, while the San Luis Valley Subbasin (approximately 8,000 acres) includes both unincorporated County and the City of San Luis Obispo.

In 2015, the State legislature approved an important new groundwater management law known as the Sustainable Groundwater Management Act (SGMA). SGMA requires that high and medium priority basins comply with the new law – DWR designated San Luis Obispo Valley Basin as a medium priority basin. The map below shows those areas subject to SGMA.

Santa Maria River Valley Groundwater Basin

The Santa Maria River Valley Groundwater Basin (Santa Maria Basin), DWR Bulletin 118 Basin No. 3-12 , underlies the coastal portion of the northern Santa Barbara and southern San Luis Obispo Counties. The DWR-defined Santa Maria Basin encompasses approximately 184,000 acres (288 square miles), of which approximately 61,220 acres (95.7 square miles) are within San Luis Obispo County. There are five "fringe areas" within the San Luis Obispo portion of the basin that are not subject to the adjudication stipulated in 2005. These fringe areas include the Pismo Creek Valley (approx. 1,220 acres), Arroyo Grande Valley (3,860 acres), Nipomo Valley (6,230 acres), Southern Bluffs (4,030 acres), and Cuyama River Plains (1,560 acres). Annual precipitation for the basin ranges from 13 to 17 inches with an average of 15 inches. Groundwater is found in alluvium, dune sands, and the Orcutt, Paso Robles, Pismo, and Careaga Formations of the basin. Groundwater is unconfined throughout most of the basin except in the coastal portion where it is confined.

In 2015, the State legislature approved an important new groundwater management law known as the Sustainable Groundwater Management Act (SGMA). SGMA requires that high and medium priority basins comply with the new law, with certain exceptions for certain adjudicated basins – DWR designated Santa Maria Basin as a high priority basin. SGMA does not apply to the portion of the Santa Maria basin that is at issue in the litigation (“adjudicated area”) provided that certain requirements are met. The adjudicated areas cover a majority of the basin, and are managed by the Northern Cities Management Area, Nipomo Mesa Management Area, and the Santa Maria Valley Management Area. However, the fringe areas described above must comply with the new groundwater management requirements. The maps below show both the adjudicated areas exempt from SGMA, and the fringe areas that are subject to SGMA.
