Notre Dame High senior Erin Trahan will hit the pool one last time as a Pio this week as she competes in her final LHSAA Division III Championship Swim Meet.

The most successful swimmer in Notre Dame history, with six state championships and one runner-up, Trahan will look to continue her dominance at the meet and win her fourth consecutive title in the 50-yard freestyle and her third in the 100-yard butterfly.

“She’s had a great impact on our program,” Notre Dame swimming coach Jenny Didier said. “She’s a great leader, and she’s been a great example to our younger kids coming in to follow.”

The two events have been Trahan’s domain since she arrived at Notre Dame in 2012, and she’s only improved every year. Last year’s meet featured her breaking her own Division III record in the 50-yard freestyle with a time of 23.70 seconds and breaking the LHSAA record among all divisions in the 100-yard butterfly with a time of 55.28 seconds.

Never one to rest on her laurels, Trahan has zoned in on bettering her times in both races and hopes to break LHSAA records in both.

“Those are my two main goals,” Trahan said. “Other than that, I want to enjoy my senior year. I want to make sure it doesn’t go by too fast.”

Trahan burst onto the scene as a freshman when she won her first state title and broke the Division III record in the 50-yard freestyle with a time of 24.51 seconds — the first state record in school history — and earned a silver medal in the 100-yard butterfly.

“I knew she was special before she even arrived at Notre Dame,” Didier said. “Seeing her heart in everything, she loves being out there. She’s always looking forward to what’s next. It was always fun, never a chore for her.”

She has proceeded to win and break the Division III records of both events every year since then, culminating in her most successful performance last season in which she cut 0.64 seconds off her record in the 50-yard freestyle and 1.85 seconds off her personal best in the 100-yard butterfly to break the LHSAA record.

“(Breaking the LHSAA record) was an amazing feeling,” Trahan said. “I was hoping to finish somewhere within the 55-second mark, but I wasn’t expecting a time as low as 55.3. When I saw the time on the bored I was like ‘Oh my gosh! Did I really do that?’ ”

While it’s Trahan’s last year as a Pio, the end her of senior year will mark the start of a new beginning, as she has committed to SMU, the reigning American Athletic Conference champion .

As a Mustang she will be following a group of swimmers who have excelled in her events.

This year SMU senior Isabella Arcilla broke a 16-year-old program record in the 50-meter freestyle with a time of 22.15 seconds and in 2014, Marne Erasmus broke the school record in the 100-meter butterfly with a time of 51.1 seconds.

“It’s really exciting because next year I’m going to get to swim with (Erasmus),” Trahan said. “Hopefully she’ll help me get faster and I can perform up to her level.”

While her competitive swimming career is far from over, this week will still be an emotional one for Trahan as she competes in her final meet in a Pios uniform.

“I hope I don’t cry,” Trahan said. “I’m going to miss it. High school swimming is always fun, and I don’t know what it’s going to be like next year without it.”
