White Rock Creek is a creek occupying a chain of four sub-watersheds within the Trinity River watershed. From its source near Frisco, Texas at , this creek runs south-by-south-east through suburban Dallas for where it widens into White Rock Lake, then continues south for another to its mouth on the Trinity River, of which it is a major tributary. Despite running through one of the most populous areas of Texas, and flowing under many major roads and highways, its banks remain heavily wooded and undisturbed in many places and many local parks are situated within its watershed, which is generally considered to extend to either side of its path. At least eight "White Rock Creeks" exist in the Dallas metro area; this article describes the White Rock Creek of Collin County and Dallas County, Texas which feeds into White Rock Lake. Course Intermittent in its upper reaches, the creek flows south, generally parallel to and between the Dallas North Tollway and Preston Road (State Highway 289). Its upper stretch flows from Frisco east of Preston, crossing under the Sam Rayburn Tollway State Highway 121. It crosses under Preston Road near Hedgcoxe Road in Plano. Widening slightly as it flows south and crosses Legacy Drive, the creek continues a southerly course through Plano between Preston Road and the Dallas North Tollway, narrowing again as it crosses West Spring Creek Parkway. It next crosses under West Parker Road where it passes through the Gleneagles Country Club. A number of parks encompass the creek as it next crosses under West Park Boulevard (State Highway 544). Still following a course between Preston and the Dallas North Tollway, the creek crosses West Plano Parkway, Atchison, Topeka and Santa Fe Railway tracks, President George Bush Turnpike, where it enters the City of Dallas. It continues past Frankford Road, runs through Preston Trail Golf Course, crosses under Keller Springs Road, Southern Pacific Railroad tracks, runs through Prestonwood Country Club where it is joined by McKamy Brook, then crosses Arapaho Road and Belt Line Road. After crossing Belt Line, the creek cuts east under Preston but quickly returns to a south-easterly course. From here, the creek meanders further and further east of Preston, no longer following it (or rather, Preston no longer follows the creek). The creek crosses Hillcrest Road just north of Interstate 635, it then flows under Interstate 635 just east of Hillcrest, flows adjacent to
