These dams are mapped in OpenStreetMap. The distance is a straight line from the road, not a route you can ride. We do not know whether you can get close — many dams sit behind maintenance roads that are closed to the public. Check dams (sabo dams) and weirs are excluded: they are flood-control structures and some are dangerous to approach. OpenStreetMap does not record whether a dam is a check dam, so to avoid listing one by mistake we keep only dams with a known operator, an encyclopaedia entry, or an official website. Some real dams are missed as a result.
What is on this page — for this forest road we hold a location and a name, and nothing else. OpenStreetMap records almost nothing about surfaces, and holds no closure information.
