How to spell POELAGES correctly?

If you meant "portages", then you're probably on the right track. Portages are areas where boats or canoes must be carried overland between bodies of water. Other possible suggestions may include "pollages" (a possible variant of pollution); "poleages" (perhaps related to the use of a pole in boating or construction); or "polages" (a possible misspelling of "politics" or "polls").
