Lake Oswego /ɒsˈwiːɡoʊ/ is a city in the State of Oregon, primarily in Clackamas County with small portions extending into neighboring Multnomah and Washington Counties. Located about 8 miles (13 km) south of Portland and surrounding the 405-acre (164 ha) Oswego Lake, the town was founded in 1847 and incorporated as Oswego in 1910. The city was the hub of Oregon’s brief iron industry in the late 19th century, and is today a suburb of Portland. As of the 2010 census, the city had a total population of 36,619, a 3.8% increase over the 2000 population of 35,278.
According to the United States Census Bureau, the city has a total area of 11.35 square miles (29.40 km), of which, 10.68 square miles (27.66 km) are land and 0.67 square miles (1.74 km) is covered by water. That area does not include more than 1,100 acres (4.5 km) of unincorporated land within the urban services boundary as defined by Clackamas County.
Oswego Lake is a lake, originally named Waluga (wild swan) by Clackamas Indians, which has been expanded is and currently managed by the Lake Oswego Corporation. The lake supports watercraft, and a dock floats at the lake’s east end, where boaters can disembark and walk to the nearby businesses. The main canal from the Tualatin River was dug in 1872.
Every three years, the water level in the lake is lowered several feet by opening the gates on the dam and allowing water to flow into Oswego Creek and on to the Willamette River, enabling lakefront property owners to conduct repairs on docks and boathouses. In 2010, the lake was lowered about 24 feet (7.3 m) to allow for construction of a new sewer line, the lowest lake level since 1962, when the original sewer line was installed.
The city extends up Mount Sylvania and through Lake Grove towards Tualatin.
