Bradley Lake is a natural lake on the Oregon Coast in Coos County, Oregon, United States, about 4 miles (6.4 km) south of Bandon. Its surface area is 23 acres (9.3 ha).[1] It is a popular fishing spot for rainbow trout.[3]
Bradley Lake was formed when coastal sand dunes blocked the exit of China Creek, flooding a depression, and accumulating about twenty feet of sediment. The lake has been protected from storm surges, but not tsunami waves, which dumped sand and salt water. Kelsey et al discovered evidence of seventeen such events, after radiocarbon dating of core samples, over a 4600 year period within the Cascadia subduction zone.[4][5]
