Riprap & Shoreline Work on Watts Bar Lake, Tennessee
Watts Bar Lake has 722 miles of shoreline in Roane, Rhea, Meigs and Loudon counties, and any work on the Tennessee Valley Authority's land along it needs a TVA Section 26a permit first. If your bank is undercut, slumping or shedding soil into the water, this site explains what TVA allows for riprap and other shoreline repair, which TVA, Tennessee and county approvals apply, what the winter drawdown shows you, what the work costs, and how to reach one independent local contractor. Separate guides cover dock repair, new docks and boat lifts.

On Watts Bar Lake, riprap starts with TVA
Riprap is loose rock placed along the foot or face of a bank so moving water hits stone instead of soil. Where the land at the water's edge belongs to TVA, the federal rules in 18 CFR 1304.208 decide whether stone is allowed and how it's placed, and TVA approves the plan before work starts.
TVA's first question is whether the shoreline is eroding enough to justify the treatment you're asking for. Its rule lists plant-based repair, riprap and gabions, and, only for severe erosion, retaining walls. Worth knowing: the plant-based list itself includes stone at the toe of the eroded bank, so a repair can mix rock low down with planting higher up.
The approvals are simpler on cost than on time. TVA charges no application fee for shoreline stabilization, but it aims for about 100 days to issue minor construction permits and says some take 120.
What TVA's riprap rule requires
- TVA has to find the erosion is enough to justify the treatment.
- Quarry-run or natural stone, unless TVA approves something else.
- The rock follows the bank's existing contour.
- Grading is limited to what the stone needs for a stable slope.
- Manufactured erosion-control gabions are allowed.
What it rules out
- Old tires, chunks of concrete, or scrap from a building site.
- Rebuilding land the lake has already taken.
- A wall on a bank that isn't severely eroded, unless it joins an approved wall.
- Cutting or clearing plants on TVA land without written approval.
- Any work on TVA property before TVA approves it in writing.

The approvals, in brief
Shoreline work on Watts Bar Lake can involve a federal permit from TVA, a state permit from Tennessee, a copy to the Army Corps, and a county building office. Here is who does what:
TVA Section 26a
Applications go through TVA's online system only, as of October 1, 2025. Stabilization costs nothing to apply for; a dock or boathouse is $1,000. TVA usually visits the site and aims to decide minor projects within 100 to 120 days.
Tennessee (TDEC)
A state Aquatic Resource Alteration Permit covers bank stabilization. General permit GARAP001, Repair of Eroding Banks and Shorelines, is written for it. Where a notice is required, the fee for a personal residence is $50, and coverage normally takes three to four weeks.
Army Corps and county
TVA passes a copy to the Corps' Nashville District, which normally issues nothing of its own. Roane County's codes office is in Kingston at 865-717-4230. Ask your county building office whether your project needs a local permit.
The lake drops every winter
Watts Bar is a flood-storage reservoir, so TVA lowers it each fall to make room for winter storm runoff. The drawdown starts November 1. A drop of five to six feet uncovers a band of bank that's underwater all summer, which makes it easier to see how deep an undercut goes or whether old riprap has slid.
TVA's stabilization rule doesn't set a season for riprap, so the drawdown is a chance to look and plan rather than a deadline. Fixed docks on Watts Bar must have decks at least 24 inches above full summer pool, so in winter they sit well above the water.
What the drawdown means for banks, docks and liftsWatts Bar Lake levels, per TVA
- Summer range
- Typically 740 to 741 feet
- Winter minimum
- 735 feet, held for navigation
- Drawdown starts
- November 1
- Back up
- Main-river reservoirs stay lower until late April or early May
- Flood storage
- 379,000 acre-feet
What the work costs
We haven't found published riprap prices for Watts Bar Lake or anywhere in Tennessee, so this site uses a national range and says so. Riprap is priced by the linear foot of shoreline, and Angi's 2025 national figures run from $70 to $400 a foot. Run 120 feet of bank through that range and you get $8,400 to $48,000.
Treat national numbers as a sanity check only. Plan around the written price from whoever actually walks your bank.

Kingston, the Clinch River arm and the lower lake
From the Solway Bridge down to Kingston, where the Clinch River joins the Tennessee, and from Kingston on down to Watts Bar Dam, the Department of Energy reports contaminated sediment buried in the old river and creek channels. Dredging there is restricted, and dredging permit requests are reviewed by TVA, DOE and TDEC. DOE gives dredging for a dock as an example of work that needs a permit. Riprap that doesn't dig into the lakebed isn't addressed, so ask TVA early if your job involves any excavation below the water.
How it works
This site is a referral service. It doesn't place stone or build docks. It puts lake property owners in touch with one independent local contractor, and here is what that looks like:
-
1
Tell us about the shoreline
Call or use the form. Say where on the lake you are, roughly how much bank is involved, and what you're seeing: a caving bank, rock that slid, a tired dock or a lift.
-
2
One contractor gets it
Your request goes to one independent local contractor who works on Watts Bar Lake, not to a list of companies.
-
3
They come look
The contractor contacts you, walks the shoreline or dock, and gives you a price in writing.
-
4
You decide
Hire them or don't. If you do, the contract, the TVA and state permits, the work and the payment stay between you and them.
You pay nothing for being referred.
Common questions about Watts Bar shoreline work
Does stone on my bank need TVA's OK?
When the bank is TVA land, it does. Nothing gets built, placed or cut on TVA property without TVA's written approval in advance, plants included. Applying costs nothing for shoreline stabilization. The permits guide covers the application.
Could a seawall go in rather than riprap?
Sometimes, but TVA keeps walls for two situations: erosion bad enough that a wall is TVA's judged best control, or a new wall tying into one TVA already approved. Retaining walls and seawalls has the material and placement limits.
Is there a season when riprap can't go in?
TVA's stabilization rule doesn't set one. Check the conditions on your TVA permit and any Tennessee permit coverage, which can add their own. The drawdown page explains what the lower winter water does and doesn't change.
Does Tennessee require a permit as well as TVA?
Tennessee requires an Aquatic Resource Alteration Permit for physical changes to state waters, with bank stabilization listed as an example. General permit GARAP001 covers repair of eroding banks and shorelines.
