South Dakota’s Iconic Destinations At Risk! Lake Francis Case Stands With Fort Thompson, Oacoma And More Under Flood Warning

Published on August 16, 2025

The National Weather Service (NWS) has put out a flood warning for central South Dakota, covering Buffalo and Lyman counties. This warning will last until 1:00 PM CDT on August 16, 2025, due to intense rainfall from thunderstorms that is already causing flooding in a number of places, including some popular tourist spots. Travelers in the area should stay updated and take basic safety steps while still exploring the state’s lively attractions.

Heavy Rainfall and Flooding Risks in Central South Dakota

As of 2:54 AM CDT, the NWS issued the flood warning, citing excessive rainfall amounts between 1.5 to 2 inches due to thunderstorms. This has led to ongoing flooding and is expected to continue throughout the morning, particularly in low-lying areas prone to flooding.

The affected areas, including Fort Thompson, Oacoma, Reliance, and Shelby, are well-known for their outdoor tourism, especially around the Lake Francis Case and Lake Sharpe regions. With these locations already experiencing flooding, the Crow Creek Housing, Tailrace Recreation Area, and the Lower Brule Reservation could also see disruptions in tourism activities.

Impact on Tourists and Ongoing Events in South Dakota

However, the warning does not seem to affect larger-scale tourism events or festivals across the state at this time. South Dakota’s summer tourism festivals, such as Sturgis Motorcycle Rally, which is ongoing in August, are expected to proceed with minimal disruption, as the event is taking place in areas less prone to immediate flooding.

The Sturgis Rally, which has been drawing thousands of tourists for its motorcycle races, concerts, and outdoor activities, is expected to have little to no impact from the flood warning. However, other smaller, regional events near the affected areas may see slight disruptions. Recreation at Fort Thompson and Oacoma, for example, could be limited if flooding persists throughout the day.

Safety Precautions for Tourists in the Affected Areas

The NWS urges all travelers in the affected areas to take proper safety precautions. Flooding can occur quickly, and most flood deaths result from vehicles being caught on flooded roads. Travelers should be aware of rising waters and adhere to the Turn Around, Don’t Drown advice, avoiding flooded roads altogether.

For visitors planning to explore the Crow Creek Reservation or the Lower Brule Reservation, it is crucial to check in advance for potential road closures or disruptions in local services. Tourism operators are likely to update their social media platforms and websites regularly with information on affected areas, and travelers should follow these updates closely to ensure their plans are not disrupted.

Tourism in South Dakota Remains Resilient Amid Weather Challenges

While the ongoing flooding warning may affect certain regions of central South Dakota, the state’s diverse tourism industry continues to thrive. The Black Hills area, home to attractions such as Mount Rushmore, Badlands National Park, and Custer State Park, remains unaffected by the flooding and is still welcoming tourists. Additionally, travelers seeking to explore the state’s unique cultural events and historic landmarks can continue with their plans.

A Brief Hiccup for Central South Dakota’s Tourism

To sum up, the flood warning NOAA issued for August 16, 2025, serves as a polite nudge for tourists in central South Dakota to take the forecast seriously as the downpour pushes streams to rise. We anticipate travel delays across Buffalo and Lyman counties, and popular stops like Fort Thompson and Lake Francis Case might face brief closures or slowed service. Keeping tabs on the latest from local officials will help visitors navigate around any safety hiccups.

Travelers headed south can plan on the Sturgis Motorcycle Rally proceeding as usual. Still, peeking at the Travel South Dakota site and checking official weather feeds for the latest will help anyone adjust their itinerary smoothly.
