Narrative:

A C17 departed riv on the skyes 1 departure. This procedure is built to fly right over an often used jump zone. When the C17 departed I looked to see where the jump aircraft was; and I noticed that they were at their jump altitude and heading towards the jump zone. I then determined that the jumpers would be down and not a factor for the C17. I had some lower altitude aircraft that I was vectoring around the jump zone; and when I was done; I had the C17 contact la ARTCC. I then noticed that the jump aircraft had not dropped the jumpers earlier; but instead was dropping them now; and the C17 was in close proximity. I ask the jump aircraft if they had dropped the jumpers; and they said they had; and had the 'heavy' in sight and started a descent. In the future; I need to ensure that the jump aircraft is clear of the jump zone if I am going to leave an aircraft on the skyes 1 on the departure. If the jump zone will not be clear; I will vector off of the skyes 1 to clear the jump zone.
