Deildartunguhver (Icelandic pronunciation: [ˈteiltarˌtʰuŋkʏˌkʰvɛːr̥]) is a hot spring in Reykholtsdalur, Iceland. It is characterized by a very high flow rate for a hot spring (180 liters/second) and water emerges at 97 °C (207 °F). It is the highest-flow hot spring in Europe.[a]
Some of the water is used for heating; it is piped 34 kilometres (21 mi) away to Borgarnes and 64 kilometres (40 mi) away to Akranes.
A fern called Struthiopteris fallax,[1][2] grows in Deildartunguhver. This fern is the only endemic fern in Iceland, and it does not grow anywhere else in the world.

* Combined, the 47 hot springs in Hot Springs, Arkansas, U.S., have a flow of 35 liters/second (9 gal/second) and the water is 35 to 68 °C (95 to 154 °F).
* The Hay-Yo-Kay Hot Springs in Truth or Consequences, New Mexico, U.S., have a flow of 99 liters/second (26 gal/second).
* Lava Hot Springs in Idaho, U.S., have a flow of 130 liters/second (34 gal/second). Glenwood Springs in Colorado, U.S., have a flow of 143 liters/second (38 gal/second).
* The Dalhousie Springs complex in Australia has a peak output of about 250 liters/second (66 gal/second) now.
* There are many very-high-flow non-thermal springs; there are 33 recognized "magnitude-one springs" (having a flow in excess of 2,800 liters/second in Florida alone. Silver Springs, Florida, U.S., has a flow of more than 23,000 liters/second (6,100.
