We use the data on the dam locations to improve our assessments of environmental impacts of dams. This allows us to better quantify trade-offs between the benefits (for example, hydropower generation, water storage) and the impacts of dams, which in turn may help to improve decision making.
You can help by identifying dams on satellite imagery and saving the locations. See here here for guidelines.
No! Just your eyes and a connection to the website.
You can delete your own entries by clicking the dam and selecting delete in the pop-up window.
We ask you to register to prevent that users accidentally delete entries of others. Also, the registration enables us to keep track of the efforts per person (and distribute mugs).
The registration details are used only to track the number of dams per person. We do not use these data for anything else.
