Narrative:

Departure station contacted us after takeoff to inform us that they had neglected to list an additional 150 pounds of cargo on the load manifest. This additional cargo caused the cargo compartment weight limitations to be exceeded by 116 pounds (maximum normally 1213 pounds). We elected not to return to the departure station because the aircraft's weight was well in excess of the maximum landing weight and aircraft control was not jeopardized.
