Tangan Barrage is located in Chapati village of Ward No. 6 of Rajagaon Union Parishad in Thakurgaon Sadar Upazila under Thakurgaon District under the auspices of Bangladesh Water Development Board in collaboration with Asia Development Bank Panchagarh Powar Division. The project was inaugurated by then-President Hussain Muhammad Ershad.
It may be mentioned here that in 1990, 44.50 hectares of land in Thakurgaon district was irrigated with wheat, boro, mustard and potato during the dry season at a cost of Tk 14 crore 82 lakh 8 thousand with the funding of the Asian Development Bank.
In front of/above the barrage, in the rainy season, the bizarre water body creates a beautiful environment for human sight. The downstream side of the barrage has a pleasant environment for visitors to sit and watch through development work including tree planting as per the protected area plan on both sides. At present, due to the expectations of the visitors of Tangan Barrage in the area, various developments including shop jute business have been achieved. The area has become usable as a picnic spot.
