A park with some excellent water-based rides requires expansion.
This park has every original RCT attraction and scenery available for research (excluding ride upgrades, i.e. Airplanes for the Suspended Roller Coaster).
White Water Park already has all the water rides built and opened, with good designs (though White Water Slide has a tendency to crash, covering the first sections after the biggest drop is a good idea). This only accounts to four ride types, and five rides, so this park needs some expansion (and little room for it).
This scenario is known as Aqua Park in the American version of the game, and is translated as Pure or Clear Water Park in the French version. Also, the rides in the American version don't have names.
There are some minor differences between the vanilla and RCT Classic version of this scenario. Walls and a roof have been added to the bridge at the park entrance. Wooden and tall wooden fences from the Jurassic Themeing have been built around the station of White Water Rapids. Furthermore, the list of available and researched rides is now upgraded.
Looking at guests' thoughts about White Water Slide at the beginning of the scenario reveals that the ride only recently crashed, as some guests are avoiding it, thinking it isn't safe.
There's a video on Youtube showing a player beating the scenario in a handful of minutes, using only ad campaigns. This player plays the scenario on OpenRCT2, and uses the "Turbo Speed" and "auto-completion when goals are met" features this game offers.
