Apart from the coastline OpenStreetMap contains a lot of other data on surface waterbodies like lakes, rivers and reservoirs. In OpenStreetMap data based maps these are typically renderered from a rendering database that also contains most of the other data used in the map.
For the coarse scales (low zoom levels) this data is however too detailed and voluminous to be rendered efficiently. We here offer a compact version of this data reduced significantly in volume and complexity which still produces results very close to those with the full detail data when rendered in plain color without outlines.

The results of this can be downloaded here.
Reduced waterbodies as raster masks
Raster files representing the global waterbodies reduced in data volume for very efficient plain color rendering at low zoom levels.
Reduced waterbodies as polygons
Polygon data representing the global waterbodies reduced in data volume for efficient plain color rendering at low zoom levels with less styling limitations.
