Enya released four singles from "Watermark" between 1988 and 1991. "Orinoco Flow" was the lead single, released in October 1988 and entered the United Kingdom singles chart at twenty-nine. It climbed to number five in its second week before it reached number one in its third, staying at the top for three consecutive weeks. The single was certified silver by the BPI for 250,000 copies sold in its first month of release. Dickins observed that some of the public were confused on the song's title and were asking shop staff for "Sail Away", so he ordered to have the title changed on subsequent pressings to "Orinoco Flow (Sail Away)". The single became a crossover hit in the United States after the single gained airplay on progressive rock, Top 40, and new age format radio stations. "Evening Falls..." was also released in 1988, and peaked at number three in Ireland and number 20 in the United Kingdom. "Storms in Africa" followed, and reached number 12 in Ireland and 41 in the United Kingdom. In 1991, after "Exile" was used on the soundtracks of "Green Card" (1990) and "L.A. Story" (1991), it was released as the album's fourth single. A music video was produced for each single with Michael Geoghegan as director, and included on the video compilation "Moonshadows", released on VHS and LaserDisc by Warner Music Vision and Warner Reprise Video in 1991.
