The South Platte River is one of the two principal tributaries of the Platte River. Flowing through the U.S. states of Colorado and Nebraska, it is itself a major river of the American Midwest and the American Southwest/Mountain West. Its drainage basin includes much of the eastern flank of the Rocky Mountains in Colorado, much of the populated region known as the Colorado Front Range and Eastern Plains, and a portion of southeastern Wyoming in the vicinity of the city of Cheyenne. It joins the North Platte River in western Nebraska to form the Platte, which then flows across Nebraska to the Missouri. The river serves as the principal source of water for eastern Colorado. In its valley along the foothills in Colorado, it has permitted agriculture in an area of the Colorado Piedmont and Great Plains that is otherwise arid.

The Denver, South Park, and Pacific Railroad was a historic 3 ft narrow gauge railroad that operated in Colorado in the western United States in the late 19th century. The railroad opened up the first rail routes to a large section of the central Colorado mining district in the decades of the mineral boom. The railroad took its name from the fact that its main line from Denver ascended the Platte Canyon and traversed South Park, hence its popular name "The South Park Line." Founded in 1872 by Colorado Governor John Evans, the company was purchased by the Union Pacific Railway in 1880, though it continued to be operated independently. The line went bankrupt in 1889 and was reorganized under a new corporate name as the Denver, Leadville and Gunnison Railway. When the Union Pacific went bankrupt in 1893, the DL&G lines went into receivership and were eventually sold to the Colorado and Southern Railway. In the first half of the 20th century, nearly all the company's original lines were dismantled or converted into 4 ft 8+1⁄2 instandard gauge. The last train to run the old DSP&P tracks was from Como, Colorado on April 11, 1937. A section of the standard gauge line between Leadville and Climax is still operated as a passenger excursion railroad called the Leadville, Colorado and Southern Railroad. At its peak the Denver, South Park and Pacific Railroad had 335 miles (539 km) of narrow gauge line, making it the largest narrow gauge railroad in the state of Colorado.

Lakewood Gulch drains a section of Lakewood and west Denver, Colorado into the South Platte River. It is the historic location of the old Interurban Shortline Railway and, in 2008, is a greenbelt that includes Rude Park, Sanchez Park and Lakewood Gulch Park.

It contains a part of the route of the (current) heritage streetcar Platte Valley Trolley and the Denver sections of the creek have an adjacent bike path. According to the Jefferson County Colorado Place Names Directory, "Lakewood Gulch originates on the north east foot of Green Mountain in Lakewood, flows east through Sixth Avenue West Park and Red Rocks Community College and continues east through Lakewood into Denver, where it joins the South Platte River southwest of the intersection of I-25 and Colfax Avenue."
