Whetstone Brook is a tributary of the Connecticut River that runs through the heart of Brattleboro, Vermont, in the United States. It flows into the Connecticut at an elevation of 250 feet (76 m) above sea level.[1] The headwater for the brook is at Hidden Lake, which is 1,500 feet (460 m) above sea level in the town of Marlboro.[1] Of the 28-square-mile (73 km2) watershed, over two thirds is contained within Brattleboro, while another 30 percent is in Marlboro. The remaining 2% is within the town of Dummerston.[1] The brook is crossed by Creamery Covered Bridge in West Brattleboro, which was built in 1879. The original Abenaki name for the waterway is Kitadowôganisibosis.[2]
