Fetid means smelling strongly of rot. Fetid water, a fetid smell, fetid and stagnant.
It is stronger than musty and more specific than smelly — fetid names the smell of decay, which is why it suits stagnant water and neglected drains. It is formal and literary. Note the spelling, which is fetid rather than foetid in modern use, and that the Latin means to stink.
