Riparia is an extinct town in Whitman County, in the U.S. state of Washington. The GNIS classifies it as a populated place.
A post office called Riparia was in operation between 1882 and 1963.[1] The community most likely took its name from a nearby riparian zone.[2]
Riparia was a railway stop along the Snake River approximately 81 miles Northeast of Pasco, WA. The town featured a bridge across the Snake River and a hotel.
From April 6th, 1917 (coinciding with the declaration of war on the German Empire) till October 16th, 1917 a detachment of Company F 2nd Idaho Infantry garrisoned Riparia to guard railroad and waterway infrastructure from sabotage concerns.[3] September 19th, 1917 the unit was redesignated Company F, 116th Engineer Regiment, 41st Division.[4]
