Are Lake Memphremagog and Lake Prespa both freshwater lakes?
Lake Memphremagog Lake Memphremagog (French: "Lac Memphrémagog" ) is a fresh water glacial lake located between Newport, Vermont, United States and Magog, Quebec, Canada. The lake spans both Quebec and Vermont, but is mostly in Quebec. Most of the watershed that feeds the lake is located in Vermont, and is a source for accumulated phosphorus, sediments and other pollutants. Recent cleanup efforts have started to improve the water quality. The lake furnishes potable (drinking) water for 200,000 people.
Seerhein The Seerhein ("Lake Rhine") is a river about four kilometres long, in the basin of Lake Constance. It is the outflow of the Upper Lake Constance and the main tributary of the Lower Lake Constance. The water level of the lower lake is about 30 cm below the level of the Upper Lake. It is considered part of the Rhine, which flows into Lake Constance as the Alpine Rhine and flows out of the Lake as the High Rhine. The Seerhein arose after the last Ice Age (the Würm glaciation, about 9650 BCE). Some time after this period, the water level of Lake Constance gradually dropped by about ten metres and the shallow parts fell dry. Some parts of the Seerhein still have a character a bit like a lake.
