History
Rockland claims its founding in 1879, 11 years before Idaho achieved its statehood in 1890. The Rockland Valley was traveled by trappers before its founding, but its first permanent settlers entered the valley in 1878. At that time, Hidalgo Guadelupe Valdez herded his cattle into the valley and chose the valley as his home. In efforts to establish his home he dug a ditch from the East Fork Creek as means to irrigate his 30 acres of land. Thus, he was granted his "Water Right" on Feb. 15, 1879. Not only was he the first settler in the valley, but also the first irrigated farmer in the valley.
