What Makes Sheridan Lake an Underwater Ghost Town?
When Spring Creek was dammed in 1939, the rising waters swallowed Sheridan whole — streets, mine shafts, and all — transforming what was once a bustling gold mining camp into one of South Dakota’s most unusual ghost towns.
Unlike most abandoned towns you can walk through, this ghost town sits roughly 20 feet beneath Sheridan Lake’s surface, permanently sealed away from casual exploration.
Sheridan’s story began in 1875 as Golden City, a hard-rock mining settlement that once served as Pennington County’s first county seat.
The Queen Bee and Calumet mines drove its growth, but exhausted gold deposits drove its decline.
By 1920, only 10 residents remained. The dam simply finished what the failing mines started.
For you, underwater exploration here isn’t possible — but knowing an entire town rests beneath those rippling waters makes the view extraordinary.
How Did Sheridan Lake Flood an Entire Ghost Town?
When you trace Sheridan’s fate, it leads directly to 1939, when workers dammed Spring Creek and forever sealed the town’s destiny beneath rising waters.
The dam’s construction wasn’t dramatic — it simply filled slowly, swallowing abandoned structures, silent mine shafts, and the old county seat’s foundations without ceremony.
Today, you’re looking at roughly 20 feet of water pressing down over what was once a living, breathing gold rush community.
Spring Creek Dam Construction
In 1939, the U.S. government dammed Spring Creek, and the rising waters swallowed what little remained of Sheridan whole. The dam construction wasn’t merely an engineering project — it was a burial.
Decades of gold rush ambition, county seat politics, and hard-rock mining history sank beneath a quiet, rippling surface.
The historical significance of this moment is striking. A town that survived fire, economic collapse, and near-total abandonment finally met its end not through neglect, but through deliberate flooding.
Spring Creek’s waters rose steadily, consuming abandoned structures, mine remnants, and the original town site in SW¼, Section 12.
Today, you’re fundamentally standing above a drowned chapter of Black Hills history whenever you visit Sheridan Lake’s shore.
That’s a road trip moment worth pausing for.
Town Submerged Underwater
Flooding a ghost town takes more than just water — it takes timing, and by 1939, Sheridan’s timing couldn’t have been worse.
When Spring Creek’s dam sealed shut, the rising waters swallowed everything — streets, mine shafts, and abandoned structures — dropping the entire town site roughly 20 feet beneath what’s now Sheridan Lake.
Today, you’re standing above a submerged chapter of Black Hills history.
There’s no underwater exploration access for the casual visitor, but that mystery sharpens the experience.
The lake’s surface ripples over what was once Pennington County’s first county seat, making Sheridan one of America’s most unusual cases of accidental historical preservation.
Drive Highway 85A eight miles north of Hill City, and you’ll find yourself gazing across waters hiding an entire forgotten world beneath you.
How to Get to Sheridan Lake on Highway 85A
To reach the submerged ghost town of Sheridan, you’ll take Highway 85A north from Hill City, covering just eight miles before Sheridan Lake appears on your horizon.
The route cuts through the Black Hills landscape, tracing ground that gold miners once traveled when this territory buzzed with ambition and hard rock drilling.
You’re fundamentally driving toward a watery grave of an entire 19th-century county seat, still resting some 20 feet beneath the lake’s surface.
Highway 85A Route Access
Nestled eight miles north of Hill City, Sheridan Lake sits just off Highway 85A, making it one of the more straightforward ghost town destinations in the Black Hills.

As you approach, remember you’re traveling toward a submerged mining legacy — a county seat, a bustling camp, a failed dream — all lying roughly 20 feet underwater.
Pull over, take in the lake’s surface, and let that quiet expanse remind you that freedom sometimes means chasing stories that most travelers never bother to find.
Eight Miles From Hill City
Getting from Hill City to Sheridan Lake takes less than fifteen minutes, but you’re covering ground that once hummed with prospectors, supply wagons, and the restless ambition of a brand-new mining frontier.
Head north from Hill City on Highway 85A, and the Black Hills will reward you immediately with scenic views that feel untouched by time. Ponderosa pines crowd the roadside, granite formations push skyward, and the open road invites genuine exploration.
Eight miles in, Sheridan Lake appears. Beneath those calm waters sits an entire ghost town, submerged since 1939 when Spring Creek was dammed.
What was once Golden City, then a booming county seat, now rests silently below the surface. You’re not just arriving at a lake — you’re arriving at living history.
What Remains Visible of Sheridan Lake’s Sunken Ghost Town?
What you won’t find during underwater exploration:

What remains is the lake itself — a liquid monument to ambition, exhaustion, and abandonment.
The freedom of this road trip lies in knowing something extraordinary hides beneath ordinary water.
You’re standing above a former county seat, swallowed whole by Spring Creek’s dam in 1939.
