 The final hydrant party will be held from 1 to 3 p.m. at the Roosevelt Swim Center parking lot on August 14th. Parks and Recreation Special Events Coordinator Lindsay Myers said, The first hydrant party at Sioux Park was a huge success. It was a hot day, there were a lot of kids, and it's a lot of fun and water to go around. Last summer's hydrant party at College Park was a big success, so we're hoping for another great turnout. We're again encouraging kids to bring their squirt guns and other water toys from home. As the summer warms up, these parties will be a great way to cool off.
