2015 Map of Lucas NW

About this map

The Missouri River carves a deep valley through this portion of South Dakota, where the expansive waters of Lake Francis Case dominate the southern landscape. The terrain transitions from the upland plains of Platte Colony in the northeast down toward the rugged bluffs overlooking the water. This 2015 survey shows the critical transport corridor provided by the Platte-Winner Bridge, which connects the high ground across the river valley. Inland from the river, the landscape is defined by the agricultural grid of section lines and rural routes like Farmers Rd and 269th St. Small tributary drainages such as Snake Cr cut through the northern reaches, while the small settlement of Red Rock sits perched on the western slopes above the reservoir, illustrating the area's sparse but deliberate pattern of occupation along the Missouri's modified course.
