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.

Currently, manual observation of rainfall and water level
are being managed by the members of DHPI maintenance branch. Figure 2 shows the
rain gauge used for manual observation of at least 3 times in a day.
Observation is done at 6:00am, 12:00nn, and 6pm in local time.

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.
