It's a sign which you could see at your neighborhood pool this summer.
The city is facing a lifeguard shortage.
Without lifeguards, the city says its pools wouldn't be safe and couldn't be open.
Finding lifeguards is a little bit more difficult than it used to be.
Sioux Falls Aquatics Director Jean Pearson said "more and more kids that are in college are finding internships and are having only to work part time for us or are not able to come back to Sioux Falls for the summer."
A month from now, the city's pools will be filled with water. Right now, the city only has half as many lifeguards as it needs but it feels confident they will have enough lifeguards for each and every pool by the start of the summer season.
A pool without lifeguards could make parents nervous.
"There would be no way we would open unless we were staffed adequately. I wouldn't feel comfortable opening without adequate coverage of our pools. That would not happen. I do hope by the first part of may that we'll be sitting in a good position," Pearson said.
Most lifeguards are kids 18 and up, younger kids might be given a chance but it's not all fun in the sun.
"To do this, you have to be mature. It's not an easy job. You're dealing with life and death. It's not for everyone but I think there's an opportunity there for a lot of kids to truly shine," Pearson said.
A job as a lifeguard could be a good way to meet people, help others and of course make some extra cash.
