Links for the two sites above:

San Diego report (very slow loading)

Reports little except that it was a privately owned dam, whose owners already have agreed to $12 million (US?) in settlements for prior damages due to improper land management activities.

Boston Globe report

Says only that the search for some people still missing has been called off. Does give March 15 as the original date of the dam failure, and reports the discharge as "300 million gallons of water."

My quick calculation (not certified for accuracy) is that's about enough water to cover 3/4 square mile one foot deep. The reports cited don't really give enough info for anyone not familiar with local conditions to know whether it's a local news event that happened to involve someone known in Boston, or if it represents something of more general significance.

Sympathy and concern of course extends to those injured/missing/killed, and to their families and friends.

Comments from someone who knows more?
