Marked Tree Lock and Siphons
Marked Tree Lock and Siphons, Flood control facility in Poinsett County, United States
The facility contains three steel tubes measuring 228 feet in length and 9 feet in diameter, positioned on a levee along the St. Francis River.
The Memphis District Corps of Engineers constructed the siphons in 1939 for Drainage District Number Seven of Poinsett County at a cost of 215,000 dollars.
The dedication ceremony in June 1939 gathered hundreds of people to witness the engineering achievement that would protect local communities from flooding.
The structure operates through a vacuum pump system that lifts water over an earthen levee and deposits it into the river channel without requiring continuous energy.
The facility features a concrete lock stretching 130 feet with a control house managing four gates, while the siphons maintain a 97.1 percent operating efficiency.
