The initial survey for checking potential observation site at the Zaung Tu Dam was participated by University of Tokyo (UTokyo) members Mr. Akira Kodaka, Dr. Ralph Allen Acierto, and Mr. Shin Yonehara. The group also joined by three member of Department of Hydropower Planning Implementation. Mr. Oo Kyaw Aye (Staff Officer, Civil) was from the Investigation Branch, while Mr. Kyaw Win Hlaing and Mr. Thaung Htike was from the Maintenance Branch. The group left the accommodation at 6:30am using a 4-wheel-drive (4WD) vehicle due to the rough terrain going to Zaung Tu Dam. Zaung Tu dam is accessible during the dry season through the roads for almost 4hours (one-way) drive using a 4WD vehicle. However, during the rainy season the area is accessible primarily through using a pump engine boat along the Bago River. The travel time during rainy season would take at least 7hours one-way from Zaung Tu Weir according to the DHPI and Department of Hydropower Generation Enterprise (DHGE) officers. This is compared to around 3-4hours drive on dry season from Zaung Tu Weir. The members of DHPI and Mr. De Par Aung (plant manager, DHGE officer) were kind enough to give a tour around the facilities in Zaung Tu Dam. Figure 1 shows the powerhouse of the Zaung Tu Dam that has a 20MW capacity using two hydropower turbines.

The initial survey was done to check potential sites for the future installation of weather observation system at Zaung Tu dam. Several sites were selected and considered near the powerhouse area due to a relatively flat area and less number of trees. Figures 3 to 7 shows the other dam facilities such as intake structure, spillway, and embankment.
