Central Valley Tulare Basin Plan Beneficial Uses

<div style='text-align:Left;'><div><div><p><span>The California State Water Resources Control Board is currently in the process of improving the functionality and accessibility of information residing in their Water Quality Control Plans (aka Basin Plans). In order to achieve this, the data (i.e. statewide water quality objectives, beneficial uses, applicable TMDLs, etc.), are being transferred to a standardized digital format and linked to applicable surface water features. This dataset is limited to the beneficial uses data, while the water quality objectives, applicable TMDLs, etc. will be released at a later date. Data formats will include GIS data layers and numerous nonspatial data tables. The GIS layers contain hydrography features derived from a 2012 snapshot of the high-resolution (1:24000 scale) National Hydrography Dataset with added attribution. Nonspatial tables will contain various textual and numeric data from the Regional Basin and State Plans. The extent of the dataset covers the state of California and the non-spatial tables reflect the information and elements from the various plans used up to 2020. The GIS layers and associated attribution will enable the future integration of the various elements of the Basin Plans to ensure that all applicable Basin Plan requirements for a particular waterbody can be determined in a quick and precise manner across different modern mediums. The data are being managed and the project implemented by State and Regional Water Board staff using ESRI's ArcGIS Server and ArcSDE technology.</span></p></div></div></div>

加利福尼亚州水资源管理委员会（California State Water Resources Control Board）目前正致力于提升其《水质控制计划》（亦称流域计划，Basin Plans）内信息的功能与可访问性。为达成这一目标，相关数据（涵盖全州水质目标、有益用途、适用的最大日负荷总量（Total Maximum Daily Loads，简称TMDLs）等）正被转换为标准化数字格式，并与对应的地表水特征建立关联。本数据集仅包含有益用途相关数据，水质目标、适用的TMDLs等其余数据将在后续发布。数据格式将包括地理信息系统（Geographic Information System，简称GIS）数据图层与大量非空间数据表。其中GIS图层包含基于2012年高分辨率（1:24000比例尺）国家水文数据集（National Hydrography Dataset）快照提取的水文特征，并补充了属性信息。非空间数据表将收录来自各区域流域计划与州级计划的各类文本与数值型数据。本数据集的覆盖范围为加利福尼亚州全境，非空间数据表所反映的信息与要素均取自截至2020年所使用的各类计划文件。GIS图层及其关联属性将为后续整合流域计划的各项要素提供支撑，确保能够在各类现代媒介中快速且精准地查询某一水体的所有适用流域计划要求。本数据的管理与项目实施工作由州与区域水资源管理委员会的工作人员依托ESRI的ArcGIS Server与ArcSDE技术完成。
