Groundwater Sustainability Plan Bowman Subbasin

Tehama County Flood Control and Water Conservation District | January 31st, 2022

The Bowman Subbasin, which is entirely located within Tehama County, is comprised of approximately 122,500 acres, and relies on an average of approximately 5,200 acre-feet (AF) of groundwater annually for agriculture (1991-2019), has been identified by the California Department of Water Resources (DWR) as a very low priority subbasin. Under the Sustainable Groundwater Management Act (SGMA) of 2014, high or medium priority subbasins are required to prepare and be managed under a Groundwater Sustainability Plan (GSP, or Plan) by January 31, 2022 (California Water Code (CWC) Section 10720.7(a)(1)). Although the Bowman Subbasin is not designated as a high or medium priority subbasin, the Groundwater Sustainability Agency (GSA) received funding to develop the GSP and is leading its development in conjunction with three other GSPs being developed by the GSA. Due to size, the file has been divided into four parts. Part 1, Part 2, Part 3, Part 4

Groundwater Sustainability Plan for Big Valley (Lake County) Basin

Lake County Watershed Protection District | January 31st, 2022

The purpose of this Groundwater Sustainability Plan (GSP) is to verify and maintain sustainable groundwater management in the Big Valley Groundwater Basin (Basin Number 5

The purpose of this Groundwater Sustainability Plan (GSP) is to verify and maintain sustainable groundwater management in the Big Valley Groundwater Basin (Basin Number 5-015) by meeting the regulatory requirements set forth in the three-bill legislative package: Assembly Bill (AB) 1739 (Dickinson), Senate Bill (SB) 1168 (Pavley), and SB 1319 (Pavley) collectively known as the Sustainable Groundwater Management Act of 2014 (SGMA). Under SGMA, high- and medium-priority basins not identified as critically overdrafted must develop and submit a GSP to the California Department of Water Resources (DWR) by January 31, 2022. GSPs are prepared and implemented by Groundwater Sustainability Agencies (GSA) that are formed from local agencies or combinations of local agencies as outlined in CWC § 10723, with the goal to reach sustainability within 20 years of implementing the sustainability plans. SGMA defines sustainable groundwater management as “management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results.” Big Valley Basin was identified as a medium-priority basin by DWR based on components such as population and groundwater use; therefore, it is subject to SGMA. The Big Valley Basin GSP is being developed by the Lake County Watershed Protection District (District), which serves as the sole GSA in the Big Valley Basin. The Big Valley GSA has jurisdiction over most of the region, excluding the portion containing the Big Valley Rancheria which is governed by the Big Valley Band of Pomo Indians of the Big Valley Rancheria, a federally recognized tribe. Due to size, the file is divided into four parts. Part 1, Part 2, Part 3, Part 4 Plan approved by DWR 4/27/23

Groundwater Sustainability Plan Implementation: A Guide to Annual Reports, Periodic Evaluations, and Plan Amendments

This document provides guidance to groundwater sustainability agencies (GSAs) preparing Annual Reports, Periodic Evaluations, and Groundwater Sustainability Plan (GSP or Plan) Amendments under the Sustainable Groundwater Management Act (SGMA or Act) and the GSP Regulations. This guidance document does not create any new requirements or obligations for GSAs but is intended to clarify the necessary content of the documents already required by SGMA and the GSP Regulations.

Habitat Restoration in the Sacramento-San Joaquin Delta and Suisun Marsh: A Review of Science Programs

Delta Stewardship Council (Delta Council) | April 25th, 2013

Current plans call for the restoration of tens of thousands of acres of mainly intertidal habitat in the Sacramento-San Joaquin Delta and Suisun Marsh. Restoration on thi

Current plans call for the restoration of tens of thousands of acres of mainly intertidal habitat in the Sacramento-San Joaquin Delta and Suisun Marsh. Restoration on this scale presents both formidable challenges and tremendous opportunities. As part of its legislatively mandated oversight of Delta science programs, the Delta Independent Science Board reviewed these habitat restoration efforts. We held discussions with individuals from state and federal agencies, NGOs, consulting firms, and universities. We were impressed by their dedication, enthusiasm, and knowledge, as well as by the scientific and institutional challenges they face. Our findings and observations about the restoration efforts are grouped under a series of criteria for a successful restoration program. In such a program: the goals are clearly articulated; the design incorporates spatial and temporal context, adaptive management and flexibility, and monitoring; modeling is used in design and evaluation; planning and implementation are coordinated among projects; the necessary scientific expertise is available; and stakeholders are involved early and often. Our findings and recommendations agree with those reached independently by National Research Council (NRC) panels. For convenience, as in the Delta Plan, we use "the Delta" to encompass both the statutory Delta and Suisun Marsh.
