At the McKay Point Dam, the St. John's River splits off to the northwest, making a wide loop around Visalia before becoming Cross Creek north of Goshen, from where it flows south. The main channel of the Kaweah River continues to the southwest through farmland, with Outside Creek and Deep Creek splitting to the south before the Kaweah itself divides into Mill Creek and Packwood Creek. Mill Creek continues westward through Visalia, and Packwood Creek skirts to the south of the city, terminating in a small flood control basin. Mill Creek ends at a confluence with Cross Creek, which flows southward to the old Tulare Lake bed near Corcoran, joining a channel carrying water from the Tule River. The Kaweah Delta region, as defined by the Kaweah Delta Water Conservation District, covers about in Tulare and Kings Counties; the main cities are Visalia and Tulare.
