HI Charles,

Just a technical note as regards a dam. In Zambia and in Southern Africa in general we call the body of water a dam, this is technically not correct. A dam is the wall that holds back the water, ie it dams the water. The water behind the wall is called a reservoir or lake. In parts of the world the dam (or dam wall as we call it here) may have a different name to the lake or reservoir. For example Lake Mead in Nevada, USA (https://www.openstreetmap.org/relation/1275469#map=17/36.01666/-114.73549) is the name of the reservoir held back by the Hoover Dam, the name of the wall. The water feature, already mapped, is as a result of people digging out stone to make crushed stone, it is therefore not a reservoir but could be possibly tagged as a pond.
