What Spanish port denied the Americans the right of deposit?

Spain, which held most of the territory west of the Mississippi River, refused to acknowledge America's westernmost boundary as the Mississippi where the Treaty of Paris had set it. Spain also denied the U.S. the "right of deposit" at New Orleans, which was also in Spanish possession. A right of deposit allows one nation to temporarily store goods on foreign soil without exorbitant fees. Both of those issues inhibited American trade on the Mississippi.
