History
Nondalton is an Athabascan Indian (Tanaina and Iliamna) village. The name means "lake after lake" in their language: the village is situated along one of a line of lakes. Nondalton was first recorded in 1909. The village was originally located on the north shore of Six Mile Lake, but was moved to the present location in 1940, due to the depletion of wood and the growth of mud flats.
Subsistence hunting and fishing are the major economic activities. Government is by tribal council. There is a food store with a post office attached, a state-certified public school providing pre-kindergarten through 12th grade instruction, an outpatient medical clinic with family social services, a maintained Russian Orthodoxchurch, a fishing lodge, and a water purification plant. Uncertified water is usually piped to most houses; septic tanks are used for sewage; and electric power and telephone service is available. Nondalton is on a boil drinking water notice indefinitely.
Nondalton is isolated: there are no highways or roads connecting it to other villages. The primary means of access and egress to the village is by airplane: a privately owned airport for single-engine craft services the village.
Among the issues affecting the village at the start of the 21st century is the proposed Pebble Mine site in the vicinity of nearby Lake Iliamna.
