Narrative:

After cleared for landing on runway 35 (5400 ft of runway) I observed that a B737 was cleared for takeoff on runway 9L. That aircraft cleared our intersecting runway at about 50 ft off the ground while we were on about 1/2 mi final. As we crossed runway 9L on runway 35 for landing at about 20 ft we were pushed sideways and down with the wake of the B737. It was on the verge of being a disaster. I recovered and landed. I was heavy in weight and had 8 people on board. 1 split second longer and I was going around.
