Houlong Waipu Stone Weirs

Stone tidal weirs (石滬) in the shallows off Waipu in Houlong, Miaoli, the last intact survivors of a much larger group that once lined the coast on either side of the Houlong River. Fishermen piled beach cobbles into curved walls that trap fish as the tide falls; the technique is attributed to the Taokas (道卡斯), a Plains Indigenous people, and was later carried on by Han settlers. Hehuan (合歡) and Munai (母乃) are the two weirs standing north of the river, still tended by their owners; Miaoli County registered the group as a cultural landscape in 2015.
