石門水庫在地民眾及遊艇業者為祈求地方平安、航行順利，於每年農曆二月三日迎請「水庫媽」及百吉復興宮開漳聖王舉辦水上繞境，已有五十年歷史。此圖片是水庫的清淤船迎請神明上船「換香」祭拜時的情景。
In order to pray for local safety and smooth navigation, the local people and yacht owners of Shimen Reservoir invite the “Reservoir Mazu” (水庫媽) and the Kaizhang Shengwang(開漳聖王) of Baiji Fuxing Temple(百吉復興宮) to hold a Pilgrimage by a boat ride around the reservoir on February 3rd of the lunar calendar every year. It has a history of 50 years. This picture shows the scene of a dredging boat in the reservoir welcoming the deity on board during the “changing incense(換香)” ritual for worship.
