From wikipedia which,perhaps,might not be the very best source of info regarding the US Constitution:

In the United States of America, an interstate compact is an agreement between two or more states. Article I, Section 10 of the United States Constitution provides that "No State shall, without the Consent of Congress... enter into any Agreement or Compact with another State."

I stand corrected. Thanks for the direct pointer!
