Reports

The Sustainable Groundwater Management Act (SGMA) requires groundwater sustainability agencies (GSAs) to submit annual reports to provide information on groundwater conditions and implementation of the GSP for the prior water year.  By statute, annual reports for the prior water year (October 1, 2018 - September 30, 2019) are due April 1 for basins with adopted GSPs to the State Water Resources Control Board.  The reporting requirements are in Section 5.3 of the GSP.

This GSP presents detailed information to understand the occurrence of groundwater in the Basin and provides solutions to achieve the Basin’s sustainability goals.

Soquel Creek Water District's Report on Water Quality Relative to Public Health Goals, 2013-2015

Soquel Creek Water District's Report on Water Quality Relative to Public Health Goals, 2007 - 2009

Three-hundred and twenty line-kilometers of airborne electromagnetic (AEM) data were acquired offshore. These data spanned 20 km of coastline, extending up to 3.5 km offshore in water up to 18 m in depth. Inversion of these data resulted in resistivity models extending to depths between 50 and 200 m below sea level. The data were interpreted in conjunction with onshore monitoring well data, hydrologic and geologic reports, and electrical resistivity tomography (ERT) data to locate the freshwater/saltwater interfaces throughout the region. A resistivity-to-water-quality transform was established using well-based water quality and resistivity logging measurements. For resistivity values that could not be converted to water quality with this transform, local auxiliary information was used on a case-by-case basis to interpret the observed features. Some low resistivity anomalies were identified near the shore at depth, which were interpreted to be artifacts of the 1D assumption in the inversion scheme used for these AEM data.

We found that the acquisition of AEM data provided valuable information about water quality in the offshore extents of the aquifers, a region inaccessible to traditional monitoring methods, but one that plays an important role in the modeling, prediction, and management of saltwater intrusion.

Soquel Creek Water District is proud to report that in 2018 the District’s water met all established drinking water health standards set by the U.S. Environmental Protection Agency (USEPA) and the State Water Resources Control Board (State Water Board).

The Technical Memorandum presents the methods used to estimate the costs and benefits of the Pure Water Soquel Project (the Project).

The objective of this technical memorandum (TM) is to provide updated cost estimates for Pure Water Soquel (PWS) as well as the water transfer options presented in the Community Water Plan (CWP) to the Soquel Creek Water District (District) for comparative evaluation based on the cost. 

This document includes the responses to comments document that completes the Final Initial Study/Mitigated Negative Declaration.

Revised study for proposed advanced purified groundwater replenishment project.
