Flash Flood, Gila

When
February 27, 6:00 AM MST to 11:00 PM MST
Where
Gila County, Payson
Reported by
GOVT OFFICIAL
Coordinates
33.800, -110.812 (the zone’s center; the record gives no point)

Snowmelt and runoff from rain resulted in considerable flows in the Tonto Creek, between Payson and Roosevelt Lake. Four roads, which cross the Tonto Creek, were closed by Gila County Public Works. The Tonto Basin area was affected the most by the flood. About 300 people in several subdivisions along the east side of Tonto Creek were isolated. Secondary Forest Service roads were inaccessible due to mud. Gila County Emergency Services assisted the Sheriff's Department and the Public Works Department in ferrying medical supplies and basic food staples across Tonto Creek.

What these are

Flash Flood
Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.

After NWS Directive 10-1605, the rules offices file Storm Data by.
