Rea, 17, maintained her 100% record to clinch gold while Carlisle's triumph added to her earlier bronze medal.
Newry swimmer Peader Connolly also won a swimming silver on Wednesday.
Ballygowan's Carlisle triumphed in the 100m freestyle with Connolly winning his medal in the 200m backstroke.

Wednesday's success brought the haul of medals by Ulster competitors up to 21 over the six days and Shaun Cassidy, Regional Director of Special Olympics Ulster, described Irish performances over the past week as "incredible".
The breakdown of the Irish medals was 30 gold, 29 silver and 27 bronze.
"We have spent the week rooting for our athletes as they consistently showed skill, determination and passion in their chosen sports and we couldn't be happier with their performance," said the Special Olympics Ulster official.
"From experiencing the traditions of Abu Dhabi to building friendships and making lifelong memories, this is an experience that none of our athletes will forget.
"They are leaving the World Summer Games with much more than just medals and that is everything we could hope for."
The final day of competitive action in Abu Dhabi saw Ireland win four gold, a silver and a fourth-place ribbon in the golf competitions.
