Lake Kitaura is typical eutrophic lake in Japan. The maximum and average depth is 10 m and 4.5 m, respectively.

Lake Temo (IT10-006-A) is located in north-west Sardinia. The construction of the dam began in 1971 and ended in 1984. The reservoir lies at 226 m a.s.l. and has an area of 4.81 km2, a mean depth of 15.8 m and a maximum capacity of 91 x 106 m3. Its catchment extends for 142 km2.

Lake Cuga (IT10-003-A) is located in the north-western part of Sardinia. The reservoir was built in 1965, but its first filling was in 1975. It lies at an altitude of 114 m a.s.l. and is extended for about 58 x 106 m2, with a maximum and average depth of 45 m and 11 m, respectively. It has a volume of 34 x 106 m3. The waters are used mainly for irrigation and drinking supplies. Cuga Lake is classified as eutrophic since the early years of its filling.

Lake Monte Lerno (IT10-004-A) is located in the North East part of Sardinia in the municipality of Pattada. Its construction was completed in 1980. The catchment area is extended for 160 km2. The reservoir lies at 563 m a.s.l. and has a maximum area of 4.4 km2, a mean depth of 14.9 m and a volume of 89.5 x 106 m3 of water. Its waters are used for drinking and irrigation. Lake Monte Lerno is classified as eutrophic.

Øvre Heimdalen is located by Valdresflya in the eastern part of Jotunheimen on the border between the municipalities of Øystre Slidre and Vågå. The valley floor, which is oriented east-west, is at an altitude of 1,100 metres. The surrounding mountains reach over 1,800 m above sea level. Birch forest grows on the south-facing valley side, but the rest of the area is above the tree line. Research activity in Øvre Heimdalen began in 1957 with documentation of the trout population in Øvre Heimdalsvatn, and how the biomass, growth rate and age composition of the population were affected by environmental conditions.

Lake Cedrino (IT10-002-A) is the result of the dam on the Cedrino River built in 1984. The lake is located in the eastern centre of Sardinia. It has a surface area of 1.5 km2 and a volume of 20 x 106 m3 when it is filled to the maximum share (103 m a. s.l.), and a mean depth of 26.5 m. The catchment covers about 627 km2.

Lago Alchichica se localiza a una elevación de 2300 msnm con una profundidad 62 m y es de agua salobre.Habitan organismos endémicos y se encuentran rocas calizas de particular interés por los microorganismos que viven en ellas. Se encuentra en la Cuenca Oriental de Puebla.

Measurements of lake physics (including e.g. water temperature, alkalinity, conductivity, oxygen and Secchi depth) are part of lake monitoring, which is usually carried out by monthly sampling at many regular lake sites (5 to 17 sites depending on the intensity of the measurements over the years). The integrated sample represents the whole water column of this polymictic shallow lake with a mean lake depth of 1.2m. The measurement satisfy the analytical standards of Ö-Norm in Austria. In case of water temperature, also depth profiles were measured during some sampling periods.
