Deildartunguhver

Deildartunguhver 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. It is the highest-flow hot spring in Europe.[1]

Some of the water is used for heating, being piped 34 kilometers to Borgarnes and 64 kilometers to Akranes.

Struthiopteris fallax (Lange) S. Molino, Gabriel y Galán & Wasowicz

A fern called Struthiopteris fallax[2][3], grows in Deildartunguhver. This fern is the only endemic fern in Iceland, and it does not grow anywhere else in the world.

The Hay-Yo-Kay Hot Springs in Truth or Consequences, New Mexico has a flow of 99 liters/second. Lava Hot Springs in Idaho has a flow of 130 liters/second. Glenwood Springs in Colorado have a flow of 143 liters/second. The Dalhousie Springs complex in Australia had a peak total flow of more than 23,000 liters/second in 1915, giving the average spring in the complex an output of more than 325 liters/second. This has been reduced now to a peak total flow of 17,370 liters/second, so the average spring has a peak output of about 250 liters/second. However, there are many very-high-flow nonthermal springs; there are 33 recognized "magnitude one springs" (having a flow in excess of 2800 liters/second) in Florida alone. Silver Springs, Florida has a flow of more than 23,000 liters/second.
