context_page_description: Dairy Creek is a 10.55-mile tributary of the Tualatin River in the U.S. state of Oregon. It begins at the confluence of its east and west forks near the unincorporated community of Schefflin and meanders southeast across the Tualatin Valley to the Tualatin River near Hillsboro, in Washington County. East Fork Dairy Creek begins at 45.788446°N 123.041498°W in Columbia County, slightly north of its border with Washington County, and flows generally south for 22 miles. West Fork Dairy Creek, also about 22 miles long, forms at 45.7553899°N 123.178168°W, near the unincorporated community of Tophill, and flows generally southeast. Before railroads displaced river boats on the Tualatin, some steamships also worked the lower section of Dairy Creek, with plans to go as far up stream as Centerville.
context_section_description: The USGS monitors the flow of East Fork Dairy Creek at a station near the unincorporated community of Meacham Corner, 12.3 miles (19.8 km) from the confluence with the west fork and about 23 miles (37 km) from the mouth of Dairy Creek. The average flow at this station is 76.9 cubic feet per second (2.18 m³/s). This is from a drainage area of 33.8 square miles (87.5 km²), about 15 percent of the total Dairy Creek watershed. The maximum flow recorded there was 1,580 cubic feet per second (45 m³/s) in January 2003, and the minimum flow was 6.9 cubic feet per second (0.20 m³/s) in September 2007.
