Water_Control_Structure

Structures are locations of pumps, gates, culverts and other water control structures used by the district to operate flows in the primary water system. This layer was derived originally from a structures shapefile developed by the Engineering group. Once loaded into the WRGDB Structure EGDB feature class, all subsequent changes to the Structure GIS data have been made in this feature class. Date of last update: November 2012.本图层要素涵盖泵站、闸门、涵洞及其他水利管控设施的空间点位，用于辖区调度原水系统的水流运行。该图层最初源自工程团队开发的设施形状文件（shapefile）。在将该数据导入WRGDB结构企业地理数据库（EGDB）要素类后，后续所有针对结构GIS数据的更新均在此要素类中完成。最后更新日期：2012年11月。
