Non-perennial.
Permanent lakes or reservoirs are represented by (solid blue colour/dashed blue shading)?
Sold blue colour.
A thin purple line with a ‘pylon’ symbol (about every 2 cm) represents a (railway line/major power transmission line?
Major power transmission line.
A solid black line (with a single short check mark across the line represents a (single lane highway/single track railway line)?
