context_page_description: Boulter's Lock is a lock and weir on the River Thames in England north-east of Maidenhead town centre, Berkshire. The present 1912-built lock replaces those at this point of the river to the immediate east dating from the late 16th century and that of 1772 built by the Thames Navigation Commission. The lock is on the western side of the north-south flowing reach between the A4094 Maidenhead to Cookham road and Ray Mill Island. The name is variably used for the immediate surrounding area.
  The weir is some way upstream of the lock, at the northern end of Ray Mill Island. It is one of the most popular whitewater freestyle kayaking areas on the River Thames, as it has been modified to allow kayakers to use it without causing disruption to other river users.
context_section_description: The weir at Boulter's Lock is a popular kayaking site. A canoe/kayak flume is installed during each summer to add to a permanent fixed ramp in front of the third of the weir's six gates.
