The festival tradition is strong in Lenexa, where locals annually celebrate spinach, animals, barbecue and, today, water. Lenexa’s Waterfest runs from 5 to 8:30 p.m. at Sar-Ko-Par Trails Park (87th Street Parkway and Lackman Road). Now in its eighth year, the festival was created to sell residents on a small sales tax to fund the city’s new Watershed Division, which finds creative ways to divert storm water. This year’s festival is ultra-kid-friendly, featuring paddle-boating, water slides, face painting, balloon animals, the ubiquitous moonwalk and a powerful spray from the Lenexa Fire Department. The free event traditionally draws a few thousand people, keeping adults busy with cane-pole fishing, a live bird presentation from the Kansas City Zoo and music from local band the Rain Dogs. The first 1,000 attendees score free hot dogs. For more information, call 913-477-7658.
