Notes: Not all rivers for the watersheds are shown - only those rivers that exist within the DNPAB are displayed (this website’s primary focus is Dartmoor after all). The catchment boundary lines (magenta) are a mixture of guesswork and research (downloaded and adjusted for Dartefacts Govt. Environment GPX data etc.) In areas with very spread apart OS map contour lines it is an eyeballing job to place a catchment line - LIDAR (LiminArc) has helped but it’s still eye-straining guesswork. Near the edges of the DNPAB some catchment boundaries can exit then enter then exit again (etc. etc.) a few times before heading finally off to the seaside for a cookie dough ice cream. In these instances the FIRST exit point is taken as THE exit point and the others (often very minor returns back into ‘Dartmoor’’ territory anyway) have been ignored. Essentially these catchment boundaries are there for general interest, to help the user see the main Dartmoor river catchments and to perhaps suggest walking routes that enable the following of catchment boundaries. Acknowledgement: The river GPX lines within this classification were first drawn by Paul Buck, tweaked by Max Piper and then adapted for integration within the Dartefacts database and map displays by Rob Naylor. Catchment Boundary lines have all been created by Rob Naylor (based on Govt. Data and OS map eyeballing). Dartefacts only displays those rivers and leats that exist within the Dartmoor National Park. As Dartefacts does not display rivers or leats that do not exist outside of the DNPA Boundary some rivers and leats are not displayed within the catchments.
