By Wikipedia Lake Oswego (IPA: ?s wi? ?o) is a city in Clackamas County, Oregon, United States. (Small parts of the city extend into Multnomah County to the north and Washington County to the west.[1]) It is located south of Portland and surrounds the private 405-acre (1.6 km˛) Oswego Lake. As of the 2000 census, the city had a total population of 35,278. Lake Oswego is notable for its reputation as one of the most affluent suburbs of Portland. In 2000, the city had a median income of $71,597, up from $57,499 in 1990. Additionally, like the rest of the Portland metropolitan area, house prices have grown rapidly (as of June 2006); the median value in 2000 was $296,200, over twice what it was in 1990 ($142,600). The city has some of the highest valued real estate in the state, particularly the homes overlooking the lake.
According to the United States Census Bureau, the city has a total area of 28.4 km˛ (10.9 mi˛). 26.8 km˛ (10.4 mi˛) of it is land and 1.6 km˛ (0.6 mi˛) of it is water. The total area is 5.57% water. Oswego Lake is a private artificial lake managed by the Lake Oswego Corporation. [2] A house with a view of Oswego Lake, or better yet a house that backs onto the lake, is likely to be very expensive and much sought after. This lake is navigable, and on a weekend, many small boats may be found plying its waters. There is a dock at the east end of the lake, where boaters can dock, disembark and go to the nearby movie theater or a nearby restaurant. Canals extending from the lake were dug by Chinese immigrants in the early part of the century. Every five to ten years, the water level in the lake is lowered 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. The lake was most recently lowered in October 2006. [2] The city extends up Mount Sylvania and through Lake Grove towards Tualatin.
