As discussed on https://www.openstreetmap.org/changeset/134061448:

 - golf=lateral_water_hazard is (for some reason) an area tag, so needs to be applied to a stream area rather than a stream way
 - The south-westernmost golf cartpath appears to be a car park access road (see the gate onto Lindeth Lane) so should be tagged as such. Added the car park to make its destination more obvious
