In times of flood

ALMIGHTY GOD, who art a very present help in time of trouble; Let not the heart of Thy people fail when fear cometh, but do Thou sustain and comfort them until these calamities be overpast: and since Thou knowest the cause and reason why this grievous disaster of flood hath fallen upon men, so do Thou heal the hurt and wounded, console the bereaved and afflicted, protect the innocent and helpless, and deliver any who are still in peril, for Thy great mercy's sake. Amen (The Presbyterian Book of Common Worship, 1906)

O ALMIGHTY Lord God, who for the sin of man didst once drown all the world, except eight persons, and afterward of Thy great mercy didst promise never to destroy it so again; We humbly beseech  Thee, that although we for our iniquities have worthily deserved a plague of rain and waters, yet upon our true repentance Thou wilt send us such weather, as that we may receive the fruits of the earth in due season; and learn both by Thy punishment to amend our lives, and for Thy clemency to give Thee praise and glory; through Jesus Christ our Lord. Amen (Book of Common Prayer)
