As you cannot build underwater, be reasonable with this setting. If this line is too high, you raised the sea level too much and begun a new flood (Noah is probably the only one who wouldn’t mind). This line marks how high water will reach so be careful when releasing that left click.

As you click and drag to adjust the sea level, you will notice a line that goes up and down across any hills you have made. To do that, select the “Move sea level” tool and hover over your sea. You can basically make oceans and seas using only terraforming tools and then later adjust the sea level at any time. Even though you can shape the land after you started a city, this is one of the reasons to do most of the work in map creation mode. This can have a much bigger effect if you claimed a large part of the water surface in the city that you’re already building. They will obstruct the traffic for a short time, but will eventually dry out. Don’t worry about waves hitting your infrastructure. That’s why it’s a good idea to define the basin where water will be, fine-tune the coast and then go with traffic (the best advice is to leave traffic for last). Each time you take away from the water surface, a huge wave will appear on the ground where you took it and will travel some distance across the map. The reason for this is that it takes a long time for water to settle down, and every change you make will take time as simulation needs to unfold. At this point, it’s a good idea to pause the game, define the water surface, unpause and fast forward – in that order. If you dig below this level and connect the hole to the map border, water will start pouring in without the need of creating a water source. This means that when you start a new map, you will be given flat land whose altitude will be 60m (try using level tool to check this value). To begin with, I need to mention that the game’s default plain level is 60. It is also important to know that all water manipulation takes time, and even if you can speed up the game’s simulation (which is highly recommended), you need to be patient. This is not valid for ponds or any other water surfaces separated from outside water.

The first thing I will cover is large water surfaces like seas and lakes. Considering what you can gain from this tool, it outweighs the learning curve and when I saw the fantastic waterfalls that some users have made, it made me want to learn more. Depending on your terrain configuration and water sources, you can create big lakes, small rivers, and fantastic waterfalls. Water can sometimes be very fickle and it takes time to see the impact on your map. Seas, Lakes and Large Water Surfaces in Cities: Skylines If you are not familiar with his name, he is famous for a large number of quality maps in the Steam workshop for Cities: Skylines, so his guide is a perfect reference.

Also, after you have read it, bear in mind it’s “as short as possible” explanation but if you want to know more, head over to this extensive and well-written guide from no other than MrMiyagi – Making Maps with Mr Miyagi – Guide, Tips and Resources. You will still have to know how terraforming tools work, so if you haven’t read the previous article, head on over here and make sure you do because I will be continuing on that. It also requires you to be patient because even if you can speed up the game simulation, it takes time for water to settle. Even if this tool has only 2 options, it is far more complicated than any other in map creating. In the previous article about Cities: Skylines, I mentioned terraforming tools and left water creating and manipulation for this article.
