Different color grass over it, a slight hump or indentation, where it goes in and where it comes out, what's growing and not growing along the line, etc.

This is why dowsers work pretty well in "real" tests (actually trying to find water, pipes etc) but in true double-blind tests like the ones SenorBeef mentioned, they fail.

Many "water dowsers" are dudes who know the area well, and can spot signs such as vegetation, rocks, dips, seeps and whatever else has proved in the past to be a good spot for a well. In this case, the "dowsing rod" just acts as a way for them to remove outside distractions and concentrate on the clues.
