You can't.  Setting the min/max zoom level at which maps come and go
is on the todo list.  Nobody's gotten to that one yet.

The fact that the roads disappear at various zoom levels is
hard-coded into the shapefile code so that the roads won't overpower
the display when you zoom out too much.  I suppose we could add that
to draw_shapefile_map() for waterways as well, keyed off of the
width of the waterway.
