Dammed If You Do

A map and infographics visualizing dam hazard in California


Dams are important, but not often thought about by members of the public, until something goes wrong. This project communicates the potential risk, with an objective of building support for dam safety in California.

What it does

Identifies and communicates the status of dams in the California division of dam safety database

How I built it

Built by Daniel Siegal, Jessica Rahman Colin Bailey, and tag along with Dan Constable ; )

Challenges We ran into


What We learned

Dam data is becoming more available, but still not complete. Assessing the potential water supply impacts from a dam damage or failure is difficult given current data availability.

What's next for Dammed if You Do

Potential interactive features using d3, incorporation of water supply data and potential impacts.
