Diamond Lake (Oregon)

The Diamond Lake is a lake in Douglas County in the south of the U.S. state of Oregon.

The lake was named after John Diamond ( has nothing to do with Diamenten ). The settlers sighted the lake for the first time in 1852, when he was on the top of a nearby shield volcano Mount Diamond, which was also named after him.

Geography

The Diamond Lake has an area of about eleven square kilometers and is only up to sixteen feet deep. He is about six miles long and two miles wide. East of the lake are the 2799 -meter-high shield volcano Mount Thielsen and west of the 2551 meter high Mount Bailey rises. He is also part of the Umpqua National Forest. Less than eight miles south begins the Crater Lake National Park.

Biology

In 1992, a population of tui chubs ( Gila bicolor Girard, 1856), an alien in Diamond Lake fish species of the family Cyprinidae, discovered. The fish increased rapidly and influenced the lake's ecosystem negatively. A decline in the population of rainbow trout and the threat of alien insect species were found.

The Oregon Department of Fish and Wildlife ( approximately Ministry of the fauna and flora of Oregon ) poisoned the waters and thus the population of tui chub in 2006 to restore the original state. The project was more successful than expected, because in 2007, a significant recovery of the ecosystem could be observed.
