Lake Isabella (also called Isabella Lake )[1][2] is a reservoir in Kern County, California created by the earthen Isabella Dam. It was formed in 1953 when the U.S. Army Corps of Engineers dammed the Kern River at the junction of its two forks at Whiskey Flat. At 11,000 acres (4,500 ha), it is one of the larger reservoirs in California. The area is in the southern end of the Sierra Nevada range and the lake itself is located in low mountains at an elevation of approximately 2,500 ft (760 m) where summer temperatures reach over 100 degrees (°F) but low enough to avoid winter snows on the surrounding ridges. Lake Isabella is located about 40 mi. northeast of Bakersfield, and is the main water supply for that city. Lake Isabella can be reached by car from Bakersfield via state Highway 178 and from Delano via Highway 155. The former towns of Isabella and Kernville were flooded by the newly created reservoir.
Isabella Dam deficiency
In 2006, Isabella Dam was found to be too unstable to hold a full amount of water and approximately 40% of a full reservoir had to be let out to restabilize the earth works.[citation needed] Presently the U.S. Army Corps of Engineers won't let the water get above 60% of capacity until an estimated 10–15 years of studies and repairs are made.(completion date needed) To further add to this problem the Isabella Dam bisects an active fault that could lead to a catastrophic failure if an earthquake occurs along it. This fault was considered inactive when the site was studied in the late 1940s.
The lake is a dividing point. Upper Kern River flows into Lake Isabella, Lower Kern River flows out of the dam and toward Bakersfield. The nearby towns of Lake Isabella and Kernville receive economic benefit from tourism created by the Lake Isabella Recreation Area and the whitewater rafting attraction of the Upper and Lower Kern River. Much of the wilderness surrounding the lake is part of the Sequoia National Forest.
