Maps are available from Sunmap. You will have to specify the catchment area you require. For advice on the extent of your catchment, contact your local Catchment or Waterwatch Coordinator or the local council. A list of Waterwatch coordinators is included in the Natural Resource Management Catalogue, a free resource sent to each school. The boundary of the catchment area can be found by tracing each waterway in the area back to its source and using these sources as the outer boundary of the catchment area.
Students identify any land uses or features that they know about.
Each group should complete a table that lists the human impacts and the possible effects on the waterways of these impacts. The information from the groups is shared in a whole class discussion. An overhead transparency of the catchment map could be used to locate various features during the discussion. Students should collate a list of the environmental issues that may impact on the catchment area.
