Memorial Day is typically regarded as the unofficial start of summer, and the target date for opening public pools.
But some pools in Western New York may not be open on time, and it's not because of the chlorine shortage.
Instead, trained lifeguards are in short supply.
WGRZ reports that the YMCA is trying to fill 20-25 open lifeguard positions for their pools and camps.
The YMCA Buffalo Niagara cites a big reason for the shortage is because they haven't held in-person training courses for new lifeguards.
The ongoing coronavirus pandemic put the usual in-person trainings on hold.
"Those trainings have been put on hold. We do have guidance on how to provide those programs to get new lifeguards trained, but the classes are smaller in size. So in a class where you might have typically 12 people, we might now only have 8. So we are limited a little bit on the number of people that are in each class."
