Horn Rapids sits on the Yakima River, just prior to it reaching the city of Richland near the intersection of SR 240 and SR 225. It is a diversion dam used to supply water to local irrigation canals. The Tri-Cities is a fun destination with a lot to offer and a lot of historical locations, of which Horn Rapids Dam is one. Members of the Yakima Indian Nation continue to use the location as a historic fishing location. Traditional Native American fishing scaffolds can be seen at the dam year round.
