Is a Dam Failing in Your Neighborhood?


A version of this story ran in the March / April 2019 issue.


How to use this map:

  1. You can sort dams by their condition — satisfactory, fair or poor — and whether they’re regulated by using the menu to the left of the map. Make sure you select criteria for both condition and regulation.
  2. Check the condition of dams in your neighborhood by using the search bar in the upper right corner of the map. You may need to zoom out a bit to see dams in your area. Click on an individual dam to see if it has ever failed, whether it’s regulated by the state and other information.
