For 100 years now, summer in the Belknap neighborhood has meant one thing — it's time for a swim.

The Lakeside Swim Club is celebrating its 100th birthday this year — they even buried a time capsule last week. So, before we dive in to the club, let's just dip our toes with a look at the former quarry-turned-lake by the numbers.

13 — the max depth of the quarry, in feet
40 — the height of the cliffs that surround the quarry, in feet
3.5 million — the number of gallons of water that fill the quarry
15,000 — the number of small-mouth bass that inhabited the quarry ~100 years ago
11 — the number of Olympic swimmers who trained at LakesideWhat's the most accurate and specific way to say this? Olympic swimmers who were former members? "Produced" just makes it sound like they came out of the lake or something

Since 1928, the club has been home to the Lakeside Seahawks swim team, which has produced 11 Olympians in its history — including "Madame Butterfly" herself, Mary T. Meagher.

The Olympians aren't the only reason the team + club are prestigious. Each year, Lakeside hosts the oldest continuously-open swim meet in the US, the Ohio Valley Championships. The competition was held for the 96th time last June.

🌊 At Lakeside, they mean lake-side

Here at LOUtoday, we strive to be hyperlocal to Derby City, but Lakeside might be even more hyperlocal than we are. Membership is limited to homeowners in the neighborhood surrounding the club + associate members who are sponsored by a neighborhood member. Basically, you gotta live nearby or know somebody who does.

Bonus: Want to go into the deep end on Lakeside's century of history? Club member Brigid Kaelin has taken a deep dive with her new book, "Lakeside," released earlier this year, including 300+ photos.
