SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

  • Draft SEIR Chapter 4.3 Biological Resources
    1 Chapter 4.3 2 BIOLOGICAL RESOURCES 3 4.3.1 Introduction 4 This chapter discusses the potential for the Proposed Program to affect biological resources. 5 Specifically, this section: (1) discusses state and federal regulations relevant to the 6 biological resources affected by the Proposed Program; (2) provides an overview of the 7 existing environmental setting throughout the state; (3) identifies wildlife and plant species 8 potentially affected by the Proposed Program; and (4) makes findings regarding the 9 significance of the Proposed Program’s impacts on biological resources. 10 The following appendices support this chapter: 11 Appendix I: Descriptions of habitat types likely to occur in or adjacent to 12 Proposed Program activities; 13 Appendix J: Species lists generated from California Natural Diversity Database 14 (CNDDB) query; 15 Appendix K: Detailed life history descriptions for Fish action species 16 Appendix L: Species‐based restrictions on Proposed Program activities 17 Appendix M. Management of Invasive Species 18 For the purposes of this chapter, the word “fish” when written as Fish refers to all wild fish, 19 mollusks, crustaceans, invertebrates, or amphibians, including any part, spawn, or ova 20 thereof, per the definition promulgated in Fish and Game Code section 45. References to fin 21 fish are written without italics and in appropriate grammatical context. 22 Organization of the Discussion of Existing Conditions 23 This chapter addresses the following aspects of the existing conditions within the context of 24 the Proposed Program. 25 “Regulatory Setting” describes state and federal regulations relevant to the 26 assessment of existing conditions and environmental consequences of the 27 Proposed Program; 28 “Environmental Setting” describes the various eco‐regions of California where 29 suction dredging may occur; and 30 “Biological Resources” lists the organisms that potentially inhabit the Program 31 Area.
