Shoal Creek is a stream found in the northeast portion of the metropolitan area, north of the Missouri River. Its watershed is about 48,000 acres and it originates near the Clay County and Platte County line north of State Route 152. From here the Creek flows east, south east where several other tributaries (many also named Shoal Creek) join it from the north and eastern parts of Clay County. It continues southeast past the intersection of I-35 and I-435 before heading to the Missouri River.
The Urban Monitoring Network consists of two sites on Shoal Creek and 1 site on the East Fork of Shoal Creek sites on Shoal Creek. The most downstream site (Site 1) is located south of the N Pleasant Valley Road Bridge as it crosses Shoal Creek. The middle site (Site 2) is located West of Missouri Route 1 near NE 76th Street. The final and most upstream site is located on the East Fork of Shoal Creek (Site 3) and is located in Hodge Park just north of NE Barry Road.
Urban land use (developed) for the watersheds above each monitoring site is 60.9%, 26.6% and 16.2% for the lower, middle and upper watersheds, respectively. Percent impervious cover for the lower, middle and upper watersheds is 18.2%, 9.5% and 2.5%, respectively.
