The Diamond Lake is a lake in Douglas County in the southern US state of Oregon .
The lake was named after John Diamond (so it has nothing to do with diamonds). The settler first sighted the lake in 1852 when he was on the summit of the nearby shield volcano Mount Diamond , which was also named after him.
geography
Diamond Lake, located at an altitude of 1580 m , has an area of approximately 11 km² and is only up to sixteen meters deep. It is about six kilometers long and two kilometers wide. East of the lake rises the 2799 meter high shield volcano Mount Thielsen and west of the 2551 meter high Mount Bailey . It is also part of the Umpqua National Forest . Crater Lake National Park begins less than five miles south .
biology
In 1992 a population of Gila bicolor ( Girard , 1856), known as Tui chub , a species of the carp family that is not native to Diamond Lake , was discovered. The fish reproduced quickly and negatively affected the lake's ecosystem. A decline in the rainbow trout population and a threat to native insect species have been noted. The Oregon Department of Fish and Wildlife then poisoned the water and with it the Tui chub population in 2006 in order to restore the original condition. The project was more successful than expected, as a significant recovery of the ecosystem could already be observed in 2007.
