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.

Fishing in Colorado has brought in a large amount of revenue for the state. In 2019 Colorado Parks and Wildlife estimated outdoor recreation contributed roughly 62 billion dollars to the state economy. Fishing was reported to be the 5th most popular outdoor activity and 110, 511 fishing and hunting combination licenses were sold. Ice fishing makes up part of this total fishing revenue and is a common annual sport for Colorado residents and out-of-state visitors. There is no legal definition of ice fishing season. Rather, people begin to ice fish once the lakes freeze over with thick enough ice. Colorado Parks and Wildlife also recommend that people always ice-fish with another person. Typically, this starts in December and ends in April for Colorado. Lakes size, depth, elevation, and seasonal weather can cause variance to the season. Once the lakes freeze over with thick enough ice, anglers go out onto the ice, drill holes through the ice, and fish for a variety of species.
