On This Day – October 30, 2015

It was a sunny October day in 2015 when I visited the Flood Control Site 14 on Thayer Road in New Ipswich. Site 14 is one of the four earthen dams built to control downstream flooding caused by the Souhegan River which originates in this town. It is designated as town conservation land so I felt the need to check it out. Here are the specifications.

The GPS Coordinates  for the center of the dam are 42°45’54.8″N 71°51’32.2″W

SITE 14 Height: 35 feet Length: 1,500 feet Maximum Storage: 885 acre-feet Hazard Classification: High hazard Areas Susceptible to Breach Flooding: Ashley Mill Road, Greenville Road, Tricnut Road, N.H. Route 124 (Old Turnpike Road), and the Mill Pond at Otis Falls. Any development along Furnace Brook and the Souhegan River between these road crossings/structures may also be susceptible to flooding.
