Memorial Day weekend -- with the school year done or nearly so, and the long days of summer stretched out in the horizon -- is the traditional start to the public pool season.

Large communities tend to have more options: Atlanta has 17 swimming pools, including four natatoriums and 13 outdoor facilities, while DeKalb County's 11 pools include 10 outdoor sites and one aquatic center. But even smaller cities have places to cannonball.

ATLANTA

Atlanta will open most of its 12 outdoor swimming pools Saturday.

The city of Atlanta also plans to open its pools at Anderson Park, Pittman Park and Thomasville Park Saturday-Monday for Memorial Day weekend. Those pools are normally closed on the weekends.

The city began operating splash pads at D.H. Stanton, Center Hill, Historic Fourth Ward and Perkerson Park earlier this month. The city also operates four indoor pool facilities year-round.

Pool fees are $2 for children, $4 for adults, and free for children ages 5 and under. For more information, call 404-546-6788.

CHEROKEE

Cherokee County has no public pools.

CLAYTON

Clayton County's three public pools are already open for the year. The pools at Steve Lundquist Aquatic Center and Virginia Gray Recreation Center are inside pools and open year-round, while the outdoor site at the Carl Rhodenizer Recreation Center opened earlier this month.

But the popular Beach at International Park in Jonesboro -- a spring-fed lake with adventure kiddie pool, slides, sandy beach, water trampoline and sun deck -- officially opens for the year Saturday.
