Found the following article online, use it to answer the question: What is named for one of the newcomers?  Before settlers moved into the basin, it consisted mainly of upland and wetland forests in which Native Americans fished, hunted, and foraged. Evidence suggests that people lived in the northern Oregon Cascade Range as early as 10,000 years ago. By 2,000 to 3,000 years ago, settlements in the Clackamas River basin, adjacent to the Johnson Creek watershed, had moved to the river's lower floodplain. The area was the home of the Clackamas Indians, a subgroup of the Chinookan speakers who lived in the Columbia River Valley from Celilo Falls to the Pacific Ocean. The Clackamas lands included the lower Willamette River from Willamette Falls at what became Oregon City to its confluence with the Columbia River and reached into the foothills of the Cascades. When Lewis and Clark visited the area in 1806, the Clackamas tribe consisted of about 1,800 people living in 11 villages. Epidemics of smallpox, malaria, and measles reduced this population to 88 by 1851, and in 1855 the tribe signed a treaty surrendering its lands, including Johnson Creek.By the middle of the 19th century, the European American newcomers had begun to remove vegetation, build sawmills, fell trees, fill wetlands, and farm in the fertile soil along Johnson Creek. The creek is named for one of these newcomers, William Johnson, who in 1846 settled in what later became the Lents neighborhood of Portland and operated a water-powered sawmill. In early 1848 Lot Whitcomb, who would later found Milwaukie, filed a donation land claim and built a sawmill near the confluence of Johnson Creek and the Willamette River. In 1886, plans were made for train tracks along the creek. In 1903, the Springwater Division Line, also known as the Portland Traction Company Line, the Cazadero Line, and the Bellrose Line, was built along Johnson Creek to provide rail transport for passengers and freight. Sellwood, Eastmoreland, Lents, and Pleasant Valley were among the new communities that grew up along the line. By the 1920s, housing began to replace creekside farms.
