Last data update: February 27, 2005 A catchment layer for a drainage line starting from where accumulated area of surface flow is 125 hectare or more. It should be noted that this is not a 125 hectare catchment thus each polygon is not 10 hectares in size, rather they are the drainage area of the 10 hectare drainage line. Each polygo has to be greater then 10 hectares. Created by LSRCA GIS staff using the 2002 DEM and ESRI Arc Hydro.
