If you own waterfront property on Lake Chatuge, rip rap erosion control is the most reliable way to keep your shoreline — and your investment — from washing into the lake. Between the Tennessee Valley Authority’s seasonal drawdown, summer boat wake, and the steep mountain banks around Hiawassee and Young Harris, Chatuge shorelines take a beating year-round. Done correctly and permitted properly, a well-built rip rap bank stops that erosion for decades.
Here’s what makes erosion control on Lake Chatuge different from any other North Georgia lake, why rip rap is the right solution, and what the process actually involves.
Lake Chatuge is a 7,000-acre TVA reservoir straddling the Georgia–North Carolina line, with roughly 132 miles of mostly privately owned shoreline winding through Towns County. It’s also the highest major lake in Georgia, tucked into the Blue Ridge — and that mountain setting is exactly why banks erode so quickly.
Three forces work against your shoreline:
There’s also a timing factor worth knowing. TVA has announced a multi-year drawdown tied to Chatuge Dam spillway repairs, expected to begin around late 2027, that would lower the lake well below its usual winter level. That means stretches of bank normally underwater will be exposed and exposed banks erode. Owners who stabilize before that drawdown protect ground that’s otherwise about to face the elements unprotected.
Rip rap is heavy, angular stone placed along the shoreline to absorb and scatter wave energy before it reaches your soil. Instead of letting waves hit bare dirt, the interlocking rock dissipates that force and holds the bank in place through fluctuating water levels, heavy rain, and wake.
It’s a proven approach on this lake for a simple reason: TVA built Chatuge Dam itself from earthen fill fortified on both sides with rip rap. The same principle that protects the dam protects your shoreline.
The catch is material. Not all rock is true rip rap. Proper rip rap-grade granite or quarry stone is angular, so the pieces lock together and stay put. Smooth river rock and decorative landscape stone shift and wash away — sometimes within a single season — leaving you to pay for the job twice. On Chatuge, the right stone choice is what separates a one-time fix from a recurring problem.
With TVA's spillway-repair drawdown ahead, banks normally underwater will be exposed and vulnerable. Armor your shoreline before it faces the elements unprotected.
Schedule My Shoreline AssessmentThis is where Lake Chatuge stands apart from lakes like Lanier. Chatuge is not governed by the U.S. Army Corps of Engineers — it’s managed by the Tennessee Valley Authority. Almost any alteration to the shoreline, including rip rap and other erosion control, requires a TVA Section 26a permit before work begins.
A few things every Chatuge owner should know:
Navigating that process on your own is daunting. As part of every rip rap project on Lake Chatuge, Martin Docks handles the permitting — gathering site drawings, submitting documentation, and coordinating directly with TVA so your installation is fully compliant from day one.
Every shoreline is different, so every project starts with a hands-on plan.
Rip rap on Lake Chatuge requires a TVA Section 26a permit. We manage the drawings, paperwork, and TVA coordination so your project is compliant from day one.
Start My Rip Rap ProjectErosion control and lake access go hand in hand. While we’re armoring your bank, it’s the ideal time to add custom shoreline or pathway steps — built into the natural topography for safe, stable access from your home to the water. A protected, well-graded bank is the perfect foundation for steps that last.
Local experience is everything on this lake. Chatuge’s soils, slopes, and TVA guidelines differ significantly from other North Georgia waters, and the right contractor knows that difference cold. Martin Docks has built and protected North Georgia shorelines for nearly 70 years, with a local office right in Hiawassee serving Lake Chatuge, Lake Nottely, and Lake Blue Ridge.
Too often, owners call us only after irreversible erosion has already cut into their property and its value. The smarter move is to protect your shoreline before that happens — especially with the coming drawdown ahead.

Most owners call us after the damage is done and property value is already lost. A little stone now saves your bank — and your investment — for decades.
Request an EstimateDo I need a permit for rip rap on Lake Chatuge? Yes. Lake Chatuge is a TVA reservoir, and shoreline stabilization — including rip rap — requires a TVA Section 26a permit before work begins. Not all waterfront lots are eligible to apply, depending on their land rights. Martin Docks manages the entire permitting process as part of your project.
How much does rip rap cost on Lake Chatuge? Cost depends on the length of your shoreline, the tons of stone required, bank slope, site access, and erosion severity. Because every Chatuge lot is different, the only accurate way to price a project is an on-site shoreline evaluation.
Is granite rip rap better than river rock? For erosion control, yes. Angular granite and quarry stone interlock and stay in place through wake and changing water levels. Smooth river rock and landscape stone tend to shift and wash out, often within a year — and TVA requires approved, natural stone anyway.
How long does rip rap last? A properly designed and installed rip rap bank can protect your shoreline for decades with minimal maintenance, because correctly sized, interlocking stone holds its position through repeated freeze-thaw, drawdown, and wave cycles.
When is the best time to install rip rap on Lake Chatuge? Lower water during the seasonal drawdown often makes for a cleaner, more durable installation. With TVA’s larger spillway-repair drawdown expected around late 2027, stabilizing now protects bank that’s otherwise about to be exposed.
