It was supposed to be Louisville’s answer to the St. Louis arch. But in the press, it was eventually called ugly. A turkey A good idea gone bad. It’s been gone since 1998, but not entirely forgotten. In fact, it’s been on Curious Louisville listener Mark Friedland’s mind: Whatever happened to the Falls Fountain? In this edition of Curious Louisville, we find out the answer.

If you're driving downtown near the river, you can't miss it: a brand new paint job in progress on the Clark Memorial Bridge. We've heard it compared to a school bus, a canary, and butter. Curious Louisville listener Allan Steinberg wanted to know how the color was chosen. (Allan's not a fan: "I was hoping it was only the primer!") WFPL's Amina Elahi went to Rebecca Metheny, the director of the Louisville Downtown Partnership. They're responsible for the paint job, and they also oversaw the KFC Yum Center design and construction--and it turns out, the two are related.

In a park off of River Road, nearly hidden by scrubby grass is a mystery: an about 50-foot wide stone circle marking long-ago infrastructure. This ring intrigued Curious Louisville listener Jim Turner, and he asked about it. “I heard [the circle] was a wading pool administered by the Louisville Water Company in the late 1800's. Is that true?” he wrote. Turner grew up in Louisville, not far from the stone circle. He remembers riding his bike from Field Elementary to the waterworks on Zorn Avenue. “The waterworks was my playground because I grew up very close to it. I rode along and through the waterworks property going places I probably shouldn't sometimes. But when you're a kid, an indestructible kid, adventurous, that's what you do.” So when one day Turner saw an old picture, taken from the distance that appeared to show a body of water — he thought maybe a pool — at the site of the stone circle, it made him curious. Turns out, this stone ring in that's now in a fairly inauspicious place — the Champions Park dog run — was actually part of a lofty nineteenth century vision of a genteel Louisville lifestyle, made possible by pumped household water: “The grounds will furnish our citizens with a delightful place of public resort where the man of business can find recreation from toil and oblivion of care, women and children obtain unrestricted exercise and amusement in the open air and the infirm consult heaven’s pure atmosphere and the genial sunlight as their medical advisors.” That’s from around 1860, when the Louisville Water Company began pumping water. And it’s a description of the park around the stone circle. Louisville Water spokeswoman Kelley Dearing Smith said she believes it was written by Charles Hermony, the company’s chief engineer and superintendent. In 1860, the water company’s major infrastructure was all located near the intersection of Zorn Avenue and River Road. There was the water tower and pump station; those are still standing. There was the city’s original reservoir, which was on a bluff where the Veterans’ Hospital is located today. And across the street, at the current site of the Champions Park dog run, was Water Works Park. A central attraction of the park was this fountain. And in 1860, it was an engineering marvel. “So what they did is, they took the pressure that was coming off of the water in the reservoir — because it's on a bluff right behind us,” Dearing Smith said. “And that pressure helped the water to shoot up into the air from the fountain.” Unfortunately, Hermony’s vision was never really fully realized. Dearing Smith said the park was damaged shortly after it was built, by soldiers walking through on their way to fight in the Civil War. There were also possibly some other problems with upkeep, and with the park not being the attraction it was expected to be. By 1879, Louisville Water had built its current Crescent Hill reservoir, and the original reservoir wasn’t needed. That stone circle is what’s still visible of the fountain. If you go into the dog park today, it’s hard to miss: it’s the site where all the little plastic wading pools are gathered, to help small dogs cool off in the summer. And Jim Turner wasn’t the only person to wonder about it. We’ve gotten a few questions at Curious Louisville, and Dearing Smith has fielded some at Louisville Water, too. Sometime this spring, Louisville Water and Metro Parks plan to put a sign at the site, so everyone who comes to the Champions Park dog run will know the history of Water Works Park.

In the middle of the Ohio River, visible from I-65 and Louisville’s Portland neighborhood, is a tiny island called “Shippingport.” You can drive to the base of the island, but you’ll be met with an array of “no trespassing” signs and wire gates. And Curious Louisville listener Ruby Fields wanted to know what was behind them.

If you’re driving down I-64, and happen to look out over the Ohio River, you may catch a glimpse of a house-like structure on top of the 14th Street Bridge. It’s small -- barely noticeable -- but a lot of people have questions about it. Including our latest Curious Louisville listener. WFPL’s Ashlie Stevens has more.

Over the last couple years, WFPL's Curious Louisville has received nearly a dozen questions about Louisville recycling. People want to know what happens after it leaves the curb, where it all goes, and how a 2017 Chinese policy impacts recycling in Kentucky. In this installment of Curious Louisville, WFPL’s Energy & Environment Reporter Ryan Van Velzer visits the largest recycling center in Louisville to answer one of our most commonly asked questions.

Traffic signals: you barely notice them until they’re not working. But what actually causes them to malfunction? That's what a Curious Louisville listener wanted know; As WFPL's Amina Elahi found out the culprit is often power, or -- more accurately -- the lack of it. Here's more:

What do Paul McCartney, Betty White and Muhammad Ali have in common? All three, along with about 100,000 other people, have been given the title “Kentucky Colonel.” But how does one gain the honor? That was listener Patrick Grantz’s question for Curious Louisville -- and our resident Kentucky Colonel, broadcast managing editor Rick Howlett, has the answer:

If you listen to our sister station WFPK, or attended Forecastle in 2016, you’ve probably heard of Pokey LaFarge He’s an artist whose music, as NPR’s Stephen Thompson once said, “evokes the old-timey spirit of a thousand crackling 78 RPM records.” LaFarge is based in St. Louis, but lived in Louisville for a time, which is what inspired his 2015 song “Home Away From Home” -- and our latest Curious Louisville question from listener Troy Richardson.

Earlier this month, Curious Louisville asked what questions you have about the JCPS audit and possible state takeover. You sent us more than 50 in the first 24 hours, and we realized we’d need to dedicate some extra time to answer them all. Here's our hour-long news special, hosted by Kentucky Public Radio’s Ryland Barton and WFPL education reporter Roxanne Scott.
