Name: Surface Water Irrigation Schemes

Display Field: SCHEME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Extent of major surface-water supplied irrigation schemes in Canterbury. Created when compiling a review of surface water irrigation schemes in Canterbury and their impacts on groundwater resources (ECan report U05/07). Attributes include scheme name, consented area, actual areas in border-dyke and spray (for some schemes), the maximum rate of take inter alia. Described in ECan report U05/07 (James Dommisse) Note availaibility of companion shape files of proposed irrigation schemes.
