With manmade channels it's far from rare. Example:

"The smaller S-58 water control structure located at the north end of 
Trout Lake generally acts as the drainage divide for flows through the 
KCOL. This is the case except under very high water conditions when 
water can be released northward through the C-32C Canal into the Lake 
Preston, Myrtle, and Joel LMA."

There's also http://en.wikipedia.org/wiki/Reversing_Falls (which in a 
general sense is oneway into the sea but on a large scale reverses daily).
