In chemistry, an alkali is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases.
Lake Baikal is a large rift lake in Russia. It is situated in southern Siberia, between the federal subjects of Irkutsk Oblast to the northwest and the Republic of Buryatia to the southeast.
Lake Constance refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (Obersee), Lower Lake Constance (Untersee), and a connecting stretch of the Rhine, called the Lake Rhine (Seerhein). These waterbodies lie within the Lake Constance Basin in the Alpine Foreland through which the Rhine flows. The nearby Mindelsee is not considered part of Lake Constance.

A kettle is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating a dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake and when the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than 10 m (33 ft) deep and eventually fill with sediment. In acidic conditions, a kettle bog may form but in alkaline conditions, it will be kettle peatland.
Lake Neusiedl, or Fertő, is the largest endorheic lake in Central Europe, straddling the Austrian–Hungarian border. The lake covers 315 km2 (122 sq mi), of which 240 km2 (93 sq mi) is on the Austrian side and 75 km2 (29 sq mi) on the Hungarian side. The lake's drainage basin has an area of about 1,120 km2 (430 sq mi). From north to south, the lake is about 36 km (22 mi) long, and it is between 6 km and 12 km wide from east to west. On average, the lake's surface is 115.45 m (378.8 ft) above the Adriatic Sea and the lake is no more than 1.8 m deep.
Lake Starnberg, or Starnberger See ) — called Lake Würm or Würmsee until 1962 — is Germany's second-largest body of fresh water, having great depth, and fifth-largest lake by area. It and its surroundings lie in three different Bavarian districts, or Landkreise. The lake is property of the state and accordingly managed by the Bavarian Administration of State-Owned Palaces, Gardens and Lakes.

The Großer Plöner See or Lake Plön is the largest lake (30 km2) in Schleswig-Holstein, Germany. It is located near the town of Plön. Its main tributary, as well as its main outflow, is the River Schwentine.
A lake is an often naturally occurring, relatively large and fixed body of water on the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers, such as Lake Ontario. Most lakes are freshwater and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water.
The Meadow Lake Tribal Council (MLTC) is a tribal council representing nine First Nation band governments in the province of Saskatchewan. The council is based in Meadow Lake, Saskatchewan.
Lille Lungegårdsvannet or Smålungeren is a small 5 acres (0.020 km2) lake in the centre of the city of Bergen in Vestland county, Norway. The octagonal lake is a natural lake that was historically connected to the nearby Store Lungegårdsvannet bay via a short strait, but the strait was filled in 1926. Today the lake is located in a park in the city centre. There is a large decorative fountain located in the central part of the lake.
Strandavatnet is a lake in Hol municipality, Norway. The lake covers an area of 23.75 square kilometres (9.17 sq mi), and lies 975 metres (3,199 ft) above sea level.' The lake is a reservoir for the Rud hydroelectric powerstation in Hovet, Buskerud. In 1952/1953 a dam was constructed which lifted the lake level 28 meters, thus the lake varies between 950 and 978 m above sea level.
