Reference to a 1946 Washington Treaty cannot be found. Perhaps you are referring to the Oregon Treaty, which was signed in Washington, D.C. on June 15, 1846. The Treaty of Oregan ended the boundary dispute concerning the Oregon Country, which had been occupied by Britain and US since the Treaty of 1818.

In 1818, the U.S. and the U.K. signed a treaty agreeing to mutually share the Oregon Country. In 1846, while James K. Polk was President, the U.S. and the U.K. signed the Oregon Treaty, giving the part from the Mexican border, which is today the California and Nevada borders, north to latitude 49° to the U.S. and giving the part north of latitude 49° to the U.K.
