National Dam Awareness Safety Day.

[Jehanne]

From the web page:

National Dam Safety Awareness Day occurs each year on May 31 to commemorate the failure of the South Fork Dam in Johnstown, Pennsylvania on May 31, 1889.  The Johnstown disaster was the worst dam failure in the history of the United States, with over 2,200 lives lost. National Dam Safety Awareness Day was created to encourage and promote individual and community responsibility and best practices for dam safety, and what steps people can take to either prevent future catastrophic dam failures or lessen the impact if a failure was to occur. Another important goal of National Dam Safety Awareness Day is to promote the benefits that dams offer.

It's just something else that the Trump administration will ignore.
