Dam

Dam is a building classified under Dams and Landscaping. It was introduced during the Closed Beta and received a notable change in Update 6: dams can now be built anywhere and are no longer restricted to Ground-Only placement.

Dams require more Logs to build than Levees. Because of their higher Log cost, dam construction represents a larger raw-material investment compared with levee construction. In game modes that penalize or limit resource availability, that higher Log requirement affects build decisions and long-term planning for water-management and landscaping projects.

• Dams were introduced in the Closed Beta and remain part of the game’s landscaping toolset.
• Update 6 changed placement rules so dams can be constructed anywhere, removing the previous Ground-Only restriction.
• Dams require more Logs to build than Levees, making them a more Log-intensive option for water-control or landscaping structures.
• In Hard mode, avoid using dams when conserving Logs is a priority; instead, use levees and floodgates to achieve similar goals while saving on Logs.

The information here is limited to documented design history, placement rules, and comparative Log cost relative to levees.
