Answer:

After his return from that expedition, Gray set sail for the northwest coast again on September 28, 1790, reaching his destination in 1792. ... On this journey aboard Columbia Rediviva Gray noticed muddy waters flowing from shore and decided to investigate his belief that it might be the "Great River of the West".
