Feature Type: Geyser
Geyser/Spring Type: Fountain geyser

Basin
Midway Geyser Basin
Complex
Flood Group

Flood Geyser is a fountain-type geyser. Erupting with bursts to 25 feet at intervals of minutes to a few hours. Commonly, Flood plays frequently with one of three types of eruptions:

Minor - every 1-4 minutes for 30 seconds
Intermediate - every 15-25 minutes for 2 - 5 minutes
Major - every 30-45 minutes for 6-8 minutes


At times though, Flood has been known to have intervals of 2-3 hours with durations of only about five minutes.


What to look for:
Flood is most easily seen from the roadside pullout at the top of the rise just south of the main Midway boardwalk area. The geyser is located at the base of the hill on the edge of the Firehole River. Flood actually has a fairly large crater. The distance and the large size of its nearby neighbor, Circle Pool, conspire to make it look small. Flood erupts from a circular crater approximately 30 feet in diameter.

Between eruptions, the water in Flood sits down a few feet. As the eruption nears, boiling in the crater begins. The boiling increases and then the water quickly rises and Flood bursts to life. Unfortunate fishermen have been caught by surprise by Flood's unexpected play. A few have been seriously burned as a result.
