The interactive map to the right allows you to view detailed stream survey and watertype data.
To zoom: double-click the map, use your mouse wheel, or use the navigation tools at the top left of the map.
Additional data layers are available by clicking the icons at the top right of the map.
When you first click on the map, this help screen will disappear, and the results of the closest survey collection point to your click will be displayed on a pane to the left. You may then click on the images in the result, or the 'watertype details' link at the top of the pane, to view additional information.
