High Resolution Maps from the Delta Plan

The following thirteen maps are listed in the Delta Plan document using a standard print resolution. These high resolution versions are being made available so that the detailed information on the maps is more easily readable.

 

  • Figure 1-1 Delta Boundaries (3.16 MB)
    The Sacramento-San Joaquin Delta and Suisun Marsh are referred to throughout the Plan collectively as “the Delta,” unless otherwise specified.  The Sacramento-San Joaquin Delta is defined in Water Code section 12220, and Suisun Marsh means the area defined in Public Resources Code section 29101 and protected by Division 19 (commencing with section 29000).

     

  • Figure 1-2 Delta Plan Study Area – Revised (863 KB)
    The Delta Watershed and Areas Receiving Delta Water - Water from the vast Delta watershed, spanning over 45,000 square miles (30 million acres), fuels both local economies and those in export areas hundreds of miles away.

     

  • Figure 1-4 The Delta Plan (2.82 MB)
    The map shows the primary area covered by the Delta Plan, including features and uses referred to in the Plan's 14 policies and 73 recommendations.

     

  • Figure 3-2 Moving and Storing California’s Water (4.97 MB)
    To provide more reliable water supplies despite the state’s hydrologic variability and diverse geography, and also to manage floods during wet years, State, federal, and local agencies have built a vast, interconnected infrastructure system throughout California.

     

  • Figure 5-1 Delta Primary & Secondary Zones & Suisun Marsh (2.50 MB)
    The Delta is composed of three areas recognized in California law. The Primary Zone is the largest and includes 490,050 acres at the heart of the Delta (Public Resources Code section 29728). The Secondary Zone includes 247,320 acres surrounding the Primary Zone (Public Resources Code section 29731). Suisun Marsh lies northwest of the Primary Zone, encompassing 106,570 acres (Public Resources Code section 29101) primarily of managed wetland. The Suisun Marsh overlaps the boundary of the Delta by about 4,300 acres.

     

  • Figure 5-2 Delta Communities (2.63 MB)
    The map shows land uses designated by city and county general plans. Within cities' spheres of influences (SOIs), the map shows land use designations proposed in city general plans, where available. In cases where cities have not proposed land uses within their SOIs, the map shows land uses designated by county general plans.

     

  • Figure 5-3 Agricultural Land Use in the Delta (4.81 MB)
    Agriculture is among the qualities that define the Delta as a place. The Delta’s initial reclamation created farmland, and ongoing maintenance of its levees and water controls allows for continued farming in the region. Agriculture dominates the Delta landscape and provides the setting for Delta residents’ communities, homes, and job sites.

     

  • Figure 5-5 State Parks and Other Protected Lands (2.87 MB)
    The map shows the locations of State parks and other protected lands in the Delta. The Delta Protection Commission estimates that about 12 million activity days of recreation occur in the Delta annually (DPC 2012b). Visitors value the wide expanses of open land, interlaced waterways, historic towns, and the lifestyle offered by the Delta.

     

  • Figure 5-6 Major Delta Resources and Recreation (3.91 MB)
    This map shows the variety and distribution of some of the recreational opportunities in the Delta. The region’s mix of land and water offers di-verse recreation experiences and facilities, including fishing, boating, bird watching, other nature activities, hunting, enjoying restaurants, campgrounds, picnic areas, and historic towns and buildings.

     

  • Figure 7-3 Levees in the Delta (2.90 MB)
    This map shows the locations of project and non-project levees in the Delta. The project levees begin on the left bank of the Sacramento River at Sherman Island and line most of the riverbanks, as well as the Sacramento River Deep Water Ship Channel and some connecting waterways north to Sacramento and beyond. On the San Joaquin River they line the riverbanks from Old River to Stockton.

 

  • Figure 7-6 Delta Flood Management Facilities (2.17 MB)
    The map shows flood management resources including flood control bypasses and floodways, along with other floodplains to be protected.  It also shows water supply reliability levee projects, flood control project levees and urban non-project levees.

Coequal goals

The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)
