City Splash is the exciting opportunity to safely swim in the Charles River! The annual state sanctioned community swim, hosted by the Conservancy, allows members of the public to experience the joy of swimming in their Charles River–the cleanest urban river in the United States!

Before every City Splash event, water quality tests are done at the event site to ensure the public’s health and safety at the swim.

History of City Splash 
The Charles River Conservancy’s first City Splash on July 13, 2013, marked one the first public community swim in the Charles River in more than fifty years. Recreational swimming has been prohibited in the Charles since the 1950’s when a growing awareness of the health risks posed by pollution in the Charles caused the beaches and bathhouses lining the river to close. After years of environmental health progress, most notably the EPA’s Charles River Initiative, swimming is now allowed through state-sanctioned events such as the Charles River Conservancy’s City Splash events and the annual Charles River Swimming Club’s One-Mile Swim Race, which began in 2007.
