July 13, 2013 in Boston was a day more than 50 years in the making, as the long-suffering Charles River was opened for recreational swimming.

After receiving a “D” grade for water quality by the U.S. EPA in 1995, the Charles began a steady road to recovery that resulted in a “B+” in 2011. And this summer, after half a century, it was once again open to swimmers — and swim they did.
