Fullerton shot a first round 91 and Barragy shot an opening-round 97.
"This was a good way to end the fall season," NIACC coach Chris Frenz said. "We played a tough course in tough conditions against solid competition.
"Sydney and Jordyn didn't score as well as they'd hoped but I like their fight."
"I felt for Ashley and Morgan," Frenz said. "Ashley is battling an illness and Morgan had an unfortunate injury occur Sunday evening.
"I'm looking forward to the spring season with this team."
