A section of the Trinity River levee in Texas has collapsed, and that is raising new concerns about the integrity of the system that shields the city from flood waters. The collapse is just off Interstate 35E at Regal Row. City of Dallas officials say that unlike most levee collapses they see, this one was caused by a water leak.

A Dallas Water Utilities water line runs across the top of the Trinity River levee where the collapse occurred; a slow leak caused the erosion leading to the damage. “This is a unique situation, obviously,” said a spokesperson from Trinity Watershed Management. “You’ve got a water line that’s running near the levee, and so you’ve got a leak, and that’s pretty unique and rare.”

There are terrific circus acts packed into "Ovo," the new Cirque du Soleil confection that opened Friday outside AT&T Park for its U.S. premiere. Death-defying Butterflies, foot-juggling Ants, contortionist Spiders, high-bounding Crickets and other bountifully talented human insects keep saving a beautifully designed show from its mind-boggling misconception and ear-punishing music.

Keep your eyes on the Butterflies, Vladimir Hrynchenko's sinuous hand-balancing, Ryo Yabe's wondrous Diabolo routine, Li Wei's deft slackwire dancing or Svetlana Belova and Nantel's anatomy-defying contortions, though, and all is well. No, the egg story never pays off. But the flying Scarabs - a trapeze act without trapezes - is a feat of aerial acrobatics you won't soon forget.
