Washa Indians. A small tribe, probably of Muskhogean stock, which, when first known to Europeans, inhabited the lower part of Bayou Lafourche, Louisiana, and hunted through the country between that river and the Mississippi. In 1699 Bienville made an unsuccessful attempt to open relations with them, but in 1718, after the close of the Chitimacha War, they were induced to settle on the Mississippi 3 leagues above New Orleans, and they appear to have remained near that place to the time of their extinction or their absorption by other tribes. They were always closely associated with another small tribe called Chaouacha, with which, they finally became united. In 1805 Sibley stated that there were only four individuals of this tribe living scattered among various French families. The name Ouacha is perpetuated in that of a lake near the Louisiana coast, and it also appears as all alternative name for Lake Salvador.
