In response to the ever-increasing demand for electrical power in the region during the early 20th century, a plan was proposed by Pacific Coast Power Company (later Puget Sound Traction Light & Power), and in 1910 the "White River Power Project" was begun. This project created a large reservoir by flooding of 4 existing lakes known as Kirtley Lake, Crawford Lake, Church Lake (formerly Kelley Lake), and Lake Tapps. The flooding was accomplished by building approximately 2.5 miles of earthen dikes which raised the water level by 35 feet, thereby joining the lakes together. The resulting 14-mile-long lake required some 20 million board feet of lumber to complete the necessary miles of flumes, canal lining, and rail trestles.
