The last day for swimming in the pools at Leeds, Lewis, Leif Erickson and Cook Parks will be Sunday August 3rd.Riverside Family Aquatic Center will remain open on a daily basis through August 13th, the day before the first day of school. Sioux City's Parks and Rec Supervisor Eric Griffith says it's been a great year at the pools. "I think it's gone great, we haven't had any staff issues," said Griffith. "We haven't had any incidents really. We did have a 911 call earlier in the year at Cook pool, but other than that, you know we always have some first aid things that was have to do at the pool, but I think the staff this year, very similar to last year, has worked well together." The Riverside pool will remain open on weekends from August 16th through Labor Day.
