Founded in 1922, the International Society of Limnology (SIL) is an organization devoted to the study of inland waters. It currently consists of around 1,250 members from 70 different countries. Since 2013, Dr Tamar Zohary has been the General Secretary-Treasurer of SIL. She is also a senior research scientist at the Kinneret Limnological Laboratory at Israel Oceanographic & Limnological Research, where her research focuses on phytoplankton ecology and the impact of water‑level fluctuations on lake ecology.

Located in the Echo Crater of the Waimangu Volcanic Rift Valley in New Zealand is Frying Pan Lake (aka Waimangu Cauldron), a natural hot spring with an approximate surface area of 3.8 hectares (9.3 acres). The average temperature of the water in the lake is 50–60°C (122–140°F). Frying Pan Lake reaches around 200 m (656 ft) across as its widest point. A bathymetric survey conducted by the New Zealand Oceanographic Institute in the 1970s calculated the average depth to be approximately 6 m (19 ft 8 in), with a maximum depth of 20 m (65 ft 7 in).
