A river was located on the Forest Moon of Endor. The Ewok Wicket Wystri Warrick once battled a hanadak in the river, and Warrick was knocked unconscious and washed up on the river's banks, where he was discovered by a group of mimphs, who took them to their nearby village. When the hanadak came to the village and began destroying it, Warrick managed to lead the hanadak to the river, where it fell down a waterfall.
