A river or lake which is dry for three months, or more, on the average?

Rivers and lakes that don’t carry water year-round are labeled as intermittent water bodies. The criterion of a three-month-or-more dry period is the standard threshold used to define an intermittent river or lake, which is why this term fits best as the map label for such features. The other terms describe broader ideas or map mechanics rather than the water body’s seasonal status: hydrography is the study of bodies of water, legend is the map key that explains symbols, and isopleths are lines of equal value (like elevation or rainfall) rather than a label for a seasonal water feature.
