In 2007 the club held its first annual one mile swim<\/a> in the Charles’ basin. This was the first sanctioned public swimming event in the river in over 50 years<\/strong>.<\/p>\n\n\n\n After decades of pollution, the Charles River has benefited from the ongoing Clean Charles River Initiative<\/a>, which was started in 1995 to restore the river’s ecological health. The river is now clean enough on most summer days to meet swimming standards. The club aims to raise awareness of and celebrate the efforts that went into cleaning the river, as well as to highlight the need for continued clean-up to enable recreational swimming in the future.<\/p>\n\n\n\n Not sure about swimming but interested in helping out with our annual swim?
