The lake surface is also 224 km² at design level. The height and capacity figures leave that surface out, so keep 224 km² beside them. The dam is about 40 km and about one hour north of the city, and also about 60 km from the city center. The one-hour figure belongs to the 40 km account. Minutes for the 60 km figure are check on arrival.
An outside look is about 30–45 minutes, with the plant below the dam closed. A registered visit is about 2–3 hours, free or very low. Do not plan a tour inside the powerhouse when the outside look is the visit. Boat tours are given as 7:00–17:00. Time on the water, and a boat fee, are check on arrival. October–April are the dry months for this reservoir, and early morning or late afternoon is the hour for the viewpoint. The dam is the trip north of town. It is not the picture of the night under Khau Ca.
