The Mother Goose Lake (English for "Mother Goose Lake") is a lake on the Alaska Peninsula in the southwest of the US state Alaska .
The 28 km² large lake is located 18 km west-northwest of the Mount Chiginagak volcano at an altitude of 23 m . The tributaries Vulcano Creek and Indecision Creek originate in the Aleutian chain . In the middle of the lake there is an island about 45 hectares in size. Mother Goose Lake is drained by the King Salmon River on the western shore of the lake. The lake and its catchment area are entirely within the Alaska Peninsula National Wildlife Refuge . There are stocks of balsam poplars ( Populus balsamifera ) on the lake shore and in the vicinity of the lake .
Acid entry in 2005
Geothermal activities of the nearby Mount Chiginagak volcano led to the melting of its glaciated mountain top in early May 2005 and the formation of an acidic crater lake with a pH value of about 3. The crater rim broke after a certain time and the acidic content of the crater lake flowed into the Mother Goose Lake. In the following years no more salmon spawned in the lake.
