Shoreline Stewardship on Old Hickory Lake

Shoreline stewardship on Old Hickory Lake starts with protecting natural vegetation, controlling runoff, removing litter safely and checking permits before altering the bank, vegetation, dock or lakebed. Gallatin’s stormwater system drains to Old Hickory Lake, while shoreline projects may involve the U.S. Army Corps of Engineers, TVA, Tennessee environmental regulators or other authorities depending on the property and proposed work. Check the responsible agency before beginning construction or vegetation removal.

For Gallatin-area lake homeowners, boaters and anglers, shoreline stewardship means more than picking up trash. It includes keeping vegetation in place, slowing polluted runoff, responding to erosion carefully and checking with the right authority before changing a bank, dock, access path or shoreline habitat.

That work matters locally because Gallatin’s stormwater system drains to streams, the Cumberland River and Old Hickory Lake. The city says runoff can carry sediment, oil, gasoline, pet waste, trash, fertilizers, pesticides and other pollutants directly into local waterways. Gallatin also identifies Old Hickory Lake as the source of the city’s drinking water.

The most useful first step is simple: leave as much natural shoreline in place as practical, keep pollutants out of runoff and contact the responsible agency before beginning physical shoreline work.

Why shoreline stewardship matters near Gallatin

Old Hickory Reservoir extends through Davidson, Sumner, Wilson, Trousdale and Smith counties. The Tennessee Wildlife Resources Agency’s reservoir report lists approximately 22,500 acres of water and 440 miles of shoreline, and documents substantial recreational fishing use.

A vegetated shoreline can slow runoff, hold soil, provide shade and support fish and wildlife habitat. The U.S. Environmental Protection Agency describes varied, layered lakeshore vegetation as a buffer that can reduce nutrient and sediment runoff, help prevent bank erosion and provide habitat.

That does not mean every bank should be left untouched or that every erosion problem can be solved with plants alone. Slopes, wave action, fluctuating water levels, drainage patterns, soil conditions, existing structures and property ownership all affect the appropriate solution. The goal is to avoid unnecessary disturbance and use a properly reviewed design when intervention is needed.

A practical stewardship checklist

Keep a natural buffer where possible

A shoreline buffer can include trees, shrubs, native grasses, wildflowers and other ground cover. The Tennessee Urban Riparian Buffer Handbook recommends native plantings and explains that established buffers generally should not be routinely mowed, although access paths and selected edges may need maintenance.

For a Gallatin-area property, consider these practices:

• Keep mature trees and established shrubs unless removal is necessary for safety or an approved project.
• Reduce the amount of closely mowed lawn immediately beside the water.
• Use native perennial vegetation suited to the site rather than introducing invasive plants.
• Keep one narrow, clearly defined access path instead of creating several informal paths down the bank.
• Avoid applying fertilizer, herbicide or pesticide near the water unless the product and application are appropriate and all applicable requirements are met.
• Do not assume that a plant is permitted simply because it is beneficial for habitat; work on TVA or federal property may require advance approval.

TVA’s shoreline regulations state that native trees, shrubs, wildflowers, native grasses and ground covers may be used to create or improve vegetative cover in the TVA shoreline management zone, while vegetation removal and chemical applications may require advance permission or an approved management plan.

Reduce runoff from yards, driveways and paths

Gallatin says its stormwater system does not send runoff to a treatment plant. Instead, stormwater can flow directly toward local streams, the Cumberland River and Old Hickory Lake.

Small property changes can reduce the amount of sediment and pollution moving downhill:

1. Direct downspouts onto stable, vegetated areas rather than toward the lake or an eroding slope.
2. Keep bare soil covered with mulch, erosion-control materials or established vegetation while work is underway.
3. Use gravel, stepping stones or other stable surfaces for heavily traveled paths where appropriate.
4. Keep leaves, grass clippings, pet waste, oil and household chemicals out of ditches, catch basins and drainage channels.
5. Inspect the route water takes during and after a heavy rain. Concentrated flow is often an early warning that a path, swale or outlet needs attention.

The city specifically warns that grass clippings, leaves, tree limbs and other debris can clog drainage structures, contribute to flooding and harm aquatic habitat.

Handle shoreline erosion before it becomes a larger project

Look for exposed roots, undercut banks, small channels carrying water toward the lake, newly bare soil, displaced rock or a receding edge. Photograph the area from several angles and note whether the problem follows rainfall, boat traffic, seasonal water-level changes or drainage from the property.

Do not treat riprap, gabions, retaining walls, fill or grading as do-it-yourself improvements without checking requirements. The Tennessee Department of Environment and Conservation lists bank sloping and stabilization, dredging, excavation, structural fill and related alterations among activities that may require an Aquatic Resource Alteration Permit or Section 401 certification.

TVA identifies shoreline stabilization as a project category under its Section 26a program, with different review categories based partly on project length and type.

The U.S. Army Corps of Engineers also manages shoreline-use rules for Old Hickory Lake. Its 2020 plan describes a goal of balancing permitted private use with protection and restoration of natural and cultural resources.

The practical rule is to document the problem first, then ask the responsible agencies what approvals and design standards apply. A contractor’s recommendation is not a substitute for agency authorization.

Remove litter and dispose of yard waste properly

Litter picked up along a public shoreline, creek or access area should be handled through an organized cleanup or the managing agency when possible. Wear gloves, use sturdy bags and do not handle unknown containers, medical waste, ammunition, fishing hooks embedded in debris or other hazardous objects. Report potentially dangerous materials to the appropriate authority rather than placing them in a household trash bag.

Gallatin’s Adopt-A-Street and Stream program offers a formal way for groups to commit to recurring cleanup and maintenance. The city says the program helps reduce stormwater pollution, protect drinking water and support recreation.

For private lakefront property, keep collected litter and yard waste out of the water and drainage system. Gallatin provides brush and leaf collection for eligible city environmental-services customers, subject to the city’s current requirements.

Protect shallow-water habitat while boating and fishing

Anglers and boaters can help by avoiding unnecessary disturbance of shallow vegetation, observing posted no-wake or restricted areas and removing fishing line, bait containers and other gear from the shoreline. Never abandon a fish attractor, brush pile or other structure in the lake without confirming that it is authorized.

TWRA describes habitat projects in Tennessee reservoirs, including fish-attractor work and efforts to establish aquatic plants that can stabilize shorelines and provide nursery cover.

Old Hickory Reservoir is a heavily used fishery. TWRA reported 518,000 hours of fishing effort on Old Hickory Reservoir in 2022, with black bass fishing representing the largest share of reported effort. That level of use makes basic practices—keeping line out of the water, respecting habitat projects and leaving natural cover undisturbed—especially important.

Permits and agency responsibilities

The agency responsible for one shoreline project may not be responsible for another. Before work begins, identify whether the proposed activity involves private land, TVA-controlled land, Corps-managed land, the lakebed, a tributary, a wetland or a public access area.

U.S. Army Corps of Engineers shoreline management

The Nashville District maintains the Old Hickory Lake Shoreline Management Plan and Resource Manager’s Office. In January 2026, the Corps announced public workshops in Gallatin and Mt. Juliet as part of an update process for the 2020 plan. The announcement identified proposed changes involving community docks and shoreline erosion-control methods.

Because the update process may affect future requirements, consult the current Old Hickory Lake plan rather than relying on an older copy. The Corps’ published contact information for the Resource Manager’s Office includes 615-822-4846 and [email protected].

TVA Section 26a review

TVA says Section 26a permission is required before certain construction, maintenance or modification activities affecting navigation, flood control or public lands within its jurisdiction. Examples can include docks, piers, boathouses, pathways, shoreline stabilization, ramps, dredging, fill and other obstructions.

TVA provides an interactive map and project guidance so applicants can check whether a property is in an eligible zone. Permission to work on TVA land is a separate concern from permission to work on privately owned land, and other local, state or federal approvals may still apply.

Tennessee water-quality permits

TDEC’s Aquatic Resource Alteration Permit program covers physical alterations to waters of the state. The agency lists examples including dredging, excavation, bank sloping, stabilization, channel relocation, structural fill and wetland work.

Ask TDEC or the permitting professional handling the project whether an ARAP, Section 401 certification or another authorization is required. Do not infer that a project is exempt because it is small, residential or intended to reduce erosion.

City of Gallatin stormwater responsibilities

The City of Gallatin’s Engineering Division handles stormwater planning, construction-plan review, inspections, complaint investigations, education and public involvement related to local water quality.

City review does not replace federal or state shoreline approvals. It may still matter when work changes drainage, affects a city road or ditch, involves construction runoff or creates an illicit discharge concern.

A seasonal maintenance plan

Spring: Inspect drainage paths, access steps, exposed roots and shoreline debris after heavy rain. Replant bare areas before runoff creates a larger channel.

Summer: Mow less near the water, watch for algae or unusual water conditions, secure boating and fishing equipment and remove litter during routine visits.

Fall: Keep leaves and brush out of ditches and the lake. Plan native planting or stabilization work early enough to complete required reviews before construction.

Winter: Review photographs from the previous year, mark changes in the bank and contact the appropriate agency before scheduling dock, vegetation or erosion work. Water-level changes can expose new areas of bank, but exposed soil is not automatically an invitation to grade or fill.

What to document before contacting an agency

Prepare a short project packet with:

• The property address and parcel information.
• A map or aerial image showing the work area.
• Photographs of the bank, access route and adjacent shoreline.
• Approximate length and height of the affected area.
• A description of the cause you suspect, such as runoff, wave action or failing drainage.
• A sketch of proposed planting, stabilization, dock or access work.
• Information about equipment, fill, rock, structures or vegetation that would be added or removed.
• Any existing permits, shoreline plans, easements or prior agency correspondence.

This information helps the agency determine which review pathway applies. It also reduces the risk of paying for a design that cannot be approved.
