IRVING (CBS 11 NEWS) – The City of Irving will balance water pollution and fireworks for Saturday’s July 4th celebration… and it’s all about Lake Carolyn.

The city is inviting thousands lakeside to view the pyrotechnics. But it is also cautioning that the water in Lake Carolyn itself is still polluted from spring floods.

On the same e-mail Irving sent out this week promoting Saturday’s extravaganza, it also cautioned Lake Carolyn’s water is not suitable for recreation.

For weeks the city has aerated and diluted the lake water; during the floods a manhole backed up… the nearby Trinity River overflowed and dropped sewage into the lake. Lakeside residents have balked about what they’ve seen floating on top.

Carliss Gruzins had a lot to say while exercising his canine buddies — Waffles and Pigtail. “Walking the dogs and stuff you can kind of see some of the stuff floating on the surface, it’s kind of gross,” he said, adding, “It’s pretty mild, you might say. I hold my dogs a little bit tighter so they don’t go running and he chases ducks so he might possibly want to run into the water.”

Lake Carolyn is the gem for much of Las Colinas. But Friday, the romantic gondola rides are on hold and paddle boarding was also forbidden. Warning posters initially took Gruzins by surprise. “We really didn’t notice it until we saw some of the signs, and then you look for it you can actually see it and you notice there’s less activity on the lake itself.”

But the pyrotechnics will go off as scheduled; the city tells CBS 11 News people were never allowed in the lake during fireworks anyway. A sentiment echoed by David Mikesa, who is planning a big watch party. “No one swims here, no one really fishes here, it’s more aesthetics,” he told CBS 11 News adding, “There’s signs saying, ‘Don’t go on the walkway, don’t swim.’ I mean, I don’t know anyone that’s swimming in this water anyhow. But for the most part I don’t see anything that’s been effected.”

Demand for lakeside table views are not effected at the tony La Cima Restaurant atop nearby Williams Square, either. But anyone hoping to watch from nearby city parks or trails are in for disappointment. The Trinity River remains over its banks and most of those areas are closed.

For romantics still needing a gondola ride — for, say, a marriage proposal — gondola rentals have moved about two miles away to nearby Lago de Claire, also located in Irving.
