U.S. Code USFWS U.S. Fish and Wildlife Service iv Section 1 Introduction 1.1 Background The United States Department of Interior Bureau of Reclamation (Reclamation) proposes to provide DOI’s WaterSMART program grant funds to the Kaweah Delta Water Conservation District (District) to construct the Paragien Basin Project. The Proposed Action consists of two groundwater recharge/stormwater control basins to provide groundwater recharge and to provide flood protection for the nearby City of Farmersville and the Linnell Farm Labor Center. The Paregien Basin site is located on the delta of the Kaweah River, south of State Highway 198 and north of the City of Farmersville. The Paregien Basin site is shown on Figures 1 and 2. It is an 80-acre parcel, bordered on the north by State Highway 198, on the south and east by the Davis Ditch of the Consolidated Peoples Ditch Company and farmland and the historic remnant of Cameron Creek to the west. With WaterSMART grants, Reclamation provides cost-shared funding on a competitive basis for on-the-ground water conservation and energy efficiency projects. The WaterSMART grant program is under the authority of Section 9504(a) of the Secure Water Act, Subtitle F of Title IX of the Omnibus Public Land Management Act of 2009, P.L. 111-11 (42 USC 10364). In accordance with the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA), this Environmental Assessment/Initial Study(EA//IS) discloses potential environmental impacts associated with the construction and operation of the two recharge basins and groundwater monitoring wells. This document uses the term Proposed Action for both the CEQA “Proposed Project” and the NEPA “Proposed Action.” This document was prepared as a joint CEQA/NEPA document because the Proposed Action is a discretionary project of a State agency with federal involvement. The District is the CEQA lead agency and Reclamation is the NEPA lead agency. The District was formed in 1927, specifically for the purposes of conserving and storing waters and protecting land from flood damage. The District encompasses a total land area of 340,000 acres as shown on Figure 1. The District holds water rights on the Kaweah River, as well as being a long-term contractor for both Class 1 and Class 2 supplies from the Friant Division of the Central Valley Project. The District’s average annual diversion from the Kaweah River is 22,803 acre-feet, while its pre-CVP contract delivery average was 19,049 acre-feet. It is anticipated that this quantity would increase by an annual average of 3,900 acre-feet based on the CVP assignment contract. The District currently has land developed for groundwater recharge purposes totaling almost 5,000 acres. Board of Directors’ policies call for continuous increases in these facilities. The Paregien Basin site was purchased by the District for specific strategic location issues including flood control, groundwater recharge purposes and habitat enhancement purposes. The current use of the property is pasture for beef cattle with a small area for raising alfalfa for the cattle. The design of facilities which comprise the Proposed Action support the continued use for this purpose. Deep Creek, a natural tributary of the Kaweah River, transects the central portion of the Paregien Basin site. 1.2 Need for Proposal The Proposed Action would allow for the construction of two recharge basins to improve groundwater recharge within the District boundary. The need for the Proposed Action, consistent with the purpose of Reclamation’s WaterSMART program, is to provide a reliable source of groundwater recharge for non-storable storm and flood waters and to improve the District's water supply management efficiency. 2 4 Section 2 Alternatives Including the Proposed Action This EA/IS considers two possible actions: the No Action Alternative and the Proposed Action. The No Action Alternative reflects future conditions without the Proposed Action and serves as a basis of comparison for determining potential effects to the human environment. 2.1 No Action Alternative Under the No Action Alternative, an average annual total of 2,370 acre-feet of groundwater supplies would not be conserved. Conservation efforts to promote the use of non-storable storm and flood waters of the Kaweah River would continue, but at a reduced rate. Groundwater levels would continue to follow their normal declining pattern and flood protection for the City of Farmersville and surrounding area would remain the same. 2.2 Proposed Action The Proposed Action consists of Reclamation providing grant funds to support the construction of two groundwater recharge/stormwater control basins, one of 19.6 acres and one of 3.4 acres, that would be used to provide a reliable source of groundwater recharge and would
