Name: Quinary Drainage Region

Display Field: catnum

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: These catchments originated from three Water Research Commission (WRC) projects. The altitudinally based quinary catchments representing hydrological and agricultural response zones (5838 upper, middle and lower quinary catchments within the RSA, Lesotho and Swaziland) emanated from the WRC climate change reports 1562/1/10 and 1843/2/11 respectively. The National Freshwater Ecosystem Priority Area project (NFEPA; WRC report 1801/2/11) employed 9417 sub-quaternary catchments as planning units to manage the water resource and the surrounding land.WRC Report No. 2020/1/12.
