摘要

The decision to remove Brantley Dam on the Dan River in Virginia was unanimous. On 18 January 2011 Danville City Council in the US voted for the 60-year old low head structure to be taken down. Originally built to divert water to an intake facility at the Brantley steam plant, the lm high, 153m long dam is no longer in use. Environmental concerns were not top of the council's agenda when they voted for the dam removal option. It was the death of a five-year-old boy in April 2010 which prompted a review of safety measures, specifically at low head dams. Four deaths have occurred at Brantley Dam over the past 45 years but these are not isolated events. Similar incidences have occurred across the US at low head dams, causing some people to label them as 'drowning machines'.
