text: Enya released four singles from Watermark between 1988 and 1991. "Orinoco Flow" was the lead single, released on 3 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 released on 12 December 1988, and peaked at number three in Ireland and number 20 in the United Kingdom. "Storms in Africa" followed on 5 June 1989, 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 on 20 May 1991. 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.
  Enya embarked on a worldwide media tour which lasted from September 1988 to May 1989 and included press, radio and television interviews and appearances, record signings, and lip-sync performances of songs from Watermark. Among her performances included "Orinoco Flow" on the British music show Top of the Pops on 19 October 1988, and "Storms in Africa" at the 1989 World Music Awards in Monte Carlo.
  At the 32nd Grammy Awards in 1990, "Orinoco Flow" was nominated for Best New Age Performance and Best Music Video.
