"Seasonal" isn't a guarantee of such things, of course, merely a guide to
probabilities, and it says that those probabilities are far higher at
times of year than at others.  "Intermittent" is also a guide to
but does not give a guide as to which times of year (or which years) are
likely than others, because such things cannot be determined, it says water
might be there or might not.  "Ephemeral" says that the might be water there
