Old Tushmanlu offstream reservoir gravity dam was constructed around the village of Tushmanlu in northern part of Mianeh, East Azerbaijan early after Islamic revolution of Iran in 1357 Iranian year. Regarding the high quality of soil and water and proper weather condition, the best quality of gardens crops has persuaded farmers to develop the area of their gardens. On the other hand, because of the poor design and construction of the traditional existing dam, studies of building a higher and more stable dam instead of old dam started by Pars Ray Ab Consulting Engineering Company in 1379 Iranian year.
