Celilo Converter Station

The Pacific DC Intertie (also called Path 65) is an electric power transmission line that transmits electricity from the Pacific Northwest to the Los Angeles area using high voltage direct current (HVDC). The line capacity is 3.1 gigawatts, which is enough to serve two to three million Los Angeles households and represents almost half of the Los Angeles Department of Water and Power (LADWP) electrical system's peak capacity.The intertie originates near the Columbia River at the Celilo Converter Station of Bonneville Power Administration's grid outside The Dalles, Oregon and is connected to the Sylmar Converter Station north of Los Angeles, which is owned by five utility companies and managed by LADWP. The Intertie can transmit power in either direction, but power flows mostly from north to south. The section of the line in Oregon is owned and operated by Bonneville Power Administration, while the line in Nevada and California is owned and operated by Los Angeles Department of Water and Power. The transition is at the Oregon–Nevada border, at 41°59′47″N 119°57′44″W. This is one of two HVDC lines serving Los Angeles; the other is Path 27.

Fifteenmile Creek is a 54-mile (87 km) long tributary of the Columbia River in the U.S. state of Oregon. It drains 373 square miles (966 km2) of Hood River and Wasco counties. Arising in the Cascade Range near Mount Hood, it flows northeast then west to its confluence with the Columbia near The Dalles. It was named "fifteenmile" because in pioneer days the main road crossed the creek about fifteen miles (24 km) from The Dalles.

The Indian Shaker Church and Gulick Homestead are an ensemble of historic buildings in The Dalles, Oregon, United States.

Gulick, an employee of the locally-important Seufert salmon canning concern, included a church building in the complex in ca. 1896 for his wife, Harriet, a member of the Wasco people. The church was the smallest of five Indian Shaker Church congregations in the state.The church and homestead were added to the National Register of Historic Places in 1978.

The Dalles Dam is a concrete-gravity run-of-the-river dam spanning the Columbia River, two miles (3 km) east of the city of The Dalles, Oregon, United States. It joins Wasco County, Oregon with Klickitat County, Washington, 300 miles (309 km) upriver from the mouth of the Columbia near Astoria, Oregon. The closest towns on the Washington side are Dallesport and Wishram. The Army Corps of Engineers began work on the dam in 1952 and completed it five years later. Slack water created by the dam submerged Celilo Falls, the economic and cultural hub of Native Americans in the region and the oldest continuously inhabited settlement in North America. On March 10, 1957, hundreds of observers looked on as the rising waters rapidly silenced the falls, submerged fishing platforms, and consumed the village of Celilo. Ancient petroglyphs were also in the area being submerged. Approximately 40 petroglyph panels were removed with jackhammers before inundation and were placed in storage before being installed in Columbia Hills State Park in the 2000s. The reservoir behind the dam is named Lake Celilo and runs 24 miles (39 km) up the river channel, to the foot of John Day Dam. The dam is operated by the U.S. Army Corps of Engineers (USACE), and the power is marketed by the Bonneville Power Administration (BPA). It is part of an extensive system of dams on the Columbia and Snake Rivers. The Dalles Dam Visitor Center, in Seufert Park on the Oregon shore, was built in 1981. A tour train was closed in autumn 2001, partly due to post-September 11 security concerns, and partly due to deteriorating track conditions and a small derailment. The Columbia Hills State Park is nearby. The Dalles Lock and Dam has been designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.The Dalles Dam is one of the ten largest hydro power producing dams in the United States. Along with hydro power, the dam provides irrigation water, flood mitigation, navigation, and recreation.
