The park also conducts realistic staff training exercises during operating hours. Visitors may occasionally see rescue practice, training mannequins or emergency-response drills.
Rain, Lightning & Weather Policy
A cloudy or rainy forecast does not automatically mean the Aqua Park is closed, but Collinsville uses specific lightning, visibility and temperature rules.
Lightning / Thunder
The waterpark closes if lightning is detected within 10 miles or thunder is heard.
30-Minute Rule
Reopening requires lightning to be outside the 10-mile radius and 30 minutes to pass after the last thunder.
70°F Opening Rule
Both air and water temperature must reach at least 70°F for normal opening.
Rain
Rain alone does not automatically close the park. Pools close if lifeguards cannot clearly see the bottom.
Tornado Warning
Guests must move to locker rooms or leave the facility and follow staff instructions.
Rain Checks
Qualifying rain checks may be issued after an official weather closure under the published conditions.
When Can You Receive a Rain Check?
Under the 2026 published policy, a rain check can be available when the facility declares a full-day closure after a qualifying weather delay and the guest meets the policy conditions.

- You must have been inside for less than two hours at closure.
- Very late entries are not eligible.
- Each guest must be present to receive the rain check.
- The rain check expires at the end of that season.
- Rain checks cannot be exchanged for cash.
Group Visits & Birthday Planning
Groups of 20 or more are asked to schedule in advance. Qualifying organized groups may have access to group pricing on Monday–Thursday rather than paying normal walk-up admission for every guest.
Birthday parties are also available during regular operating hours, but parties need to be scheduled in advance.
