Depends on the meaning. Which slough is that?
Slough (rhymes with plow) is a noun meaning a swamp, as in Bunyan's 'Slough of Despond' in Pilgrim's Progress. In some dialects it is possibly pronounced 'sloe' or 'sloff'?
Slough (sluff) is a verb for what a snake does with unwanted skin. It can possibly also be 'sloff' to some?
What's the Slough you promounce slew (rhymes with through)?
