The storm in Houston has drawn to my attention, a fact of which I was previously unaware, that there are two quite separate Colorado rivers.
In Britain we have various instances of rivers with the same name e.g. Avon, Ouse etc. But we usually distinguish them by talking about "The Great Ouse" and the "Yorkshire Ouse" etc.
Please could someone explain to me how it arose that there were two Colorado Rivers, And if I describe one as "the Texas Colorado", what do I call the other?
