Celilo Converter Station, south of the Dalles Dam. For nearly 50 years this BPA-owned facility has provided low-cost hydroelectric power to Southern California via the Pacific Intertie, a high-voltage direct current (HVDC) transmission line that runs uninterrupted for 846 miles. By steadily upgrading capacity, the 3800 Megawatt line delivers electricity to over 2 million homes in Los Angeles. Photo with labels added adapted from ABB 
With the building of The Dalles Dam in the 1950s, Native peoples were dis-placed, re-placed. Some did not move, many returned seasonally or to stay . Such a place is the Lone Pine In-Lieu Fishing Site, a federally-owned plot near river’s edge. As Molly Harbarger reports in March 2016, “ ‘We understand there are some terrible living conditions there,’ said U.S. Army Corps of Engineers' Portland District spokeswoman Diana Fredlund. Few of the sites are as bad as Lone Pine. … Lone Pine is gated, separating it from The Dalles, a hub of Columbia Gorge life. The tribal members don't have access to the city's amenities like electricity. Instead, residents have to jack it from the bathroom lights and generators."
