With Virginia and the nation celebrating 250 years of freedom from England in 2026, I thought it might be fun to occasionally bring up some local history. At one time, Botetourt County stretched all the way to the Mississippi and into Wisconsin, which means my county's history is also the history of much of the nation.
Carvins Cove is being talked about a lot these days because a Google data center is locating at The Botetourt Center at Greenfield. This is an industrial park the county created in the 1990s and its purpose has changed several times over the last 30 years.
The data center is supposed to use up to 8 million gallons of water a day when the entire thing is built out.
We recently visited the Cove. As you can see in the photos below, the lake is down considerably, as indicated by the dirt at what should be the water line at full pond. We've been in a drought situation for over a year now.
However, there is more to the story of Carvins Cove than water usage. Right now, it's a water reservoir with a conservation forest area that locals treat as both landmark and backdrop.
But beneath that calm surface lies the memory of an entire community: farms, a school, a church, a resort hotel, even an amusement park. All of it now rests under the water that supplies much of the Roanoke Valley.
This is the story of how that happened.
Before the Water: A Frontier Settlement
Carvins Cove began as a small early‑19th‑century settlement built around a grist mill on Carvins Creek. Its namesake, William Carvin, was one of the first settlers in the Hollins area and held a 150‑acre land grant along the creek.
By the late 1800s and early 1900s, the Cove had grown into a modest but lively rural community. Before its destruction, it included:
• Rocky Branch School
• Cove Alum Baptist Church
• Cove Alum Springs resort hotel
• Tuck‑Away Park, a small amusement park
• At least 60 homes
It was a place where Botetourt and Roanoke families lived, farmed, worshipped, and gathered. It was a quiet valley.
The First Rumblings of Change (1920s)
The community’s fate shifted in the early 1920s when the Virginia Water Company announced plans to build a dam to impound water in the area. By 1926, the company publicly confirmed the dam would be constructed at the falls of Carvins Creek.
An 80‑foot abutment was completed by 1928, but the reservoir itself remained unrealized for nearly two decades. The valley continued its daily life, even as the shadow of the future lake grew longer.
The Final Years of the Community (1940–1946)
Everything changed when the City of Roanoke acquired the Roanoke Water Company in 1942. With municipal backing, the reservoir project accelerated:
• The city began purchasing and condemning land throughout the Cove.
• On February 14, 1944, the last structures were auctioned off.
• In total, Roanoke acquired over 12,000 acres for about $1 million.
• In 1945, German POWs were brought in to help clear timber.
By May 1946, the reservoir filled and overtopped the dam, sealing the valley’s fate. The official dedication followed in March 1947.
What Lies Beneath
During drought years, the waterline drops enough that stone foundations and remnants of the old community reappear, ghostlike, along the shoreline.
Even when the water is high, hikers and riders sometimes notice old chimneys, walls, or roadbeds tucked into the woods. They are quiet reminders of what used to be there.
Carvins Cove Today: Water, Wilderness, and Memory
Today, Carvins Cove is:
• The primary water source for roughly 130,000 customers in the Roanoke Valley.
• One of the largest municipal parks in the United States (ranked between 2nd and 9th depending on the source).
• A major recreation area offering hiking, mountain biking, horseback riding, paddling, and fishing.
It’s also fed in part by the Tinker Creek tunnel, opened in 1966, which diverts Botetourt water under Tinker Mountain into the reservoir.
Carvins Cove is no longer a village, but it is very much alive.
Why Carvins Cove Still Matters
Carvins Cove is a rare place where natural beauty, local history, and regional infrastructure intersect. For Botetourt County, it’s a reminder of:
• The early frontier families who shaped the region
• The sacrifices made for public water access
• The way landscapes hold memory, even when transformed
Standing on the shoreline today, it’s easy to forget that a community once lived beneath your feet. But the past is still there in the foundations that surface during drought, in the old photographs preserved by local families, and in the name “Carvin,” which still echoes across the valley.
Sources include the Western Virginia Water Authority; the City of Roanoke archives; the Roanoke Times historical coverage of the Carvins Cove project; the Botetourt County and Roanoke County historical societies; the Virginia Department of Historic Resources; and regional histories documenting the Cove Alum Springs resort, the early Carvin land grants, and the 1940s reservoir construction.
