The Asotin Land and Water Company, an affiliated subsidiary of the Lewiston Clarkston Improvement Company, had originally been its competitor for the waters of Asotin Creek. In 1902, the Lewiston Water and Power Company, a predecessor to the L.C.I.C., acquired control of the Asotin Land and Water Company and efforts were begun to rebuild and expand their flume and siphon on the creek. Because of this corporate takeover, some records from the Asotin Land and Water Company remain with those of the L.C.I.C. (See The Lewiston-Clarkston Improvement Company: a register of its records, 1888-1963, in the Washington State University Library. Pullman, 1975.) The Asotin Land and Water Company retained its identity as an organization until about 1939.
