资源简介：
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.
