#3985 closed enhancement (wontfix)

Add rendering for areas tagged waterway=dam

Reported by: drnoble Owned by: mapnik-team@…

Component: mapnik Version:
Keywords: waterway, dam, render Cc:

Osmarender shows waterway=dam on an area as a thick black line e.g.

Resolution: wontfix
Status: newclosed

The "mapnik" component in trac is for the old XML-based openstreetmap.xml stylesheets which are not deployed on Since June the default style on has been openstreetmap-carto, which has its own issue tracker at

I'm going to go ahead and close this issue as wontfix to avoid people being confused by it and commenting on it instead of somewhere where it will effect the rendering on Closing it doesn't mean the issue won't be fixed in openstreetmap-carto, just that this ticket is against old unmaintained software that has been replaced and this ticket has zero chance of being resolved.

There is an openstreetmap-carto ticket requesting a distinction between unpaved and paved surfaces at, but please read the roadmap at to understand what issues are an immediate priority.
