What to write about
- A correction: the address of the page and what looks wrong. Agencies correct their own provisional values, and our pages take the corrected values on the next build.
- A removal: the page, what you want taken off it, and why.
- A question about our numbers, our sources or anything else on the site.
Not for warnings
We cannot answer questions about safety on the water. For flood warnings, use the official service of your country; for shipping, the notices of the waterway authority.
