Old Hickory Lake Dock Permits & Shoreline Rules: What Every Buyer Needs to Know

If you are moving here from somewhere with an ocean, a private pond, or a lake you could buy a piece of, the first thing to understand about Old Hickory is that it is not a lake in the way you probably picture one. It is the Cumberland River, backed up behind a federal dam at Hendersonville and stretching about 97 river miles upstream to Cordell Hull Lock and Dam at Carthage. The dam sits at Cumberland River mile 216.2, roughly 25 river miles above downtown Nashville. Old Hickory Lake is a U.S. Army Corps of Engineers project, managed by the Corps' Nashville District. It is not a TVA lake, and TVA has no ownership, management, or permitting role on this water.

That one fact governs almost everything on this page. On Old Hickory, a private dock is not a fixture that conveys with a house. It is a federal permit issued as a privilege on public land, normally for a five-year term, and it becomes null and void the day the property changes hands. Understanding that before you write an offer is the difference between buying a lake house and inheriting somebody's permit problem.

Two ground rules before the details. First, the Corps is the only authority on any specific address, so nothing here is a promise about a particular property. Second, every rule below is stated under the 2020 Old Hickory Lake Shoreline Management Plan, which is the operative document as of September 2, 2026 while a September 2025 tracked-changes draft works through review. Where the draft would change something, this guide says so.

Who owns the shoreline behind an Old Hickory Lake house?

Almost always, the United States does. The land around Old Hickory was bought under a minimum acquisition policy the Corps' own Master Plan calls the Eisenhower Policy. It limited acquisition to a line, or a series of lines along tangents, located at or near the 451-foot contour at the dam and extending to the 464-foot contour at the upper end of the lake. The Master Plan describes the result plainly: a very narrow fringe of land around the lake. Normal pool is 445 feet, so in most places the government's strip is dry land sitting above the water's edge, and a private lot ends at that line rather than at the water.

It is worth being precise about what that line is, because a common shortcut gets it wrong. The boundary is a metes-and-bounds fee line, not a readable elevation contour. The Corps' own explanation of it in the 2020 public-comment responses is to picture the bathtub ring the lake would leave if it rose about six feet: the line sits far back on flat ground and close to the water on a bluff. Acquisition did not follow a specific contour. Old Hickory also has no federal building setback from the public line, though local zoning still applies.

The line was originally surveyed, established, and marked between 1982 and 1984 with signs on metal or wooden posts and yellow blaze marks painted on trees. The Corps re-marks a section of it each year, and owners sometimes mistake that re-marking for a new survey. It is not one. The Corps states that it is the responsibility of each adjoining property owner to know the exact location of his or her property lines and corners, and disturbing the markers is destruction of government property under 36 CFR 327.14.

Since 2020 there is also a survey rule with teeth: before a new permit is issued, the line must be clearly identified, and if it is not, the new owner must use a licensed surveyor and provide a stake survey of the public property line. The Corps will supply information including bearings and distances, but the survey is at the owner's expense. If you are buying a lot where nobody can point to a blaze or a post, that is a line item to plan for, not a detail to discover later.

A flowage easement is a different thing that also carries the government's name. On easement land the Corps holds an easement interest but not fee title: the landowner keeps full use of the land subject to restrictions that maintain flood capacity and hold the government harmless for flood damage, and on a flowage easement the Corps retains the right to inundate. Fill on flowage-easement land requires written Corps approval, and minor residential landscaping fill above ordinary high water is handled case by case and capped at one vertical foot or ten cubic yards without an engineer-certified flood-storage offset plan.

One line from the Shoreline Management Plan is worth memorizing before you tour anything: these uses of public lands and waters that are permitted to adjacent landowners are privileges, not rights. Permit Condition 1 says the permit is a privilege granted by the United States. Condition 8 says it does not convey any property rights either in real estate or material, and 36 CFR 327.30 says the same. If a permit is not renewed or is revoked, the permitted facility comes out at the owner's expense.

Is my shoreline dock-eligible?

That is decided by the Shoreline Allocation Map, not by the listing. The Corps classifies every foot of Old Hickory's roughly 440 miles of shoreline into management categories, and the category controls what may exist at the water's edge. Here is how the whole lake divides under the 2020 plan, which the September 2025 draft leaves unchanged.

Read that table twice, because the half-truth in circulation is that half the shoreline can have a dock. Half of the shoreline is Limited Development, but Limited Development is sub-classified, and private and community docks are permitted only in the roughly one-third that is allocated for private docks and mowing. The other 17 percent is mowing only. The Corps explains why: many areas that may be open to mowing front shorelines that are impractical for moorage of floating docks because of steep bluffs, narrow coves, shallow water, or impacts to navigation.

Even inside the 33 percent there is no guarantee. The plan says directly that a Limited Development designation on the Shoreline Allocation Map does not guarantee that a dock permit will be issued at a specific location within that area. The decision follows a site inspection and turns on location, amount of lake frontage, pool fluctuation, shoreline characteristics, water depth — the dock must be able to float during normal pool elevation of 445 msl — and impact on public use. Docks on the main channel are coordinated with the District so commercial navigation is not impeded.

What does a lot need to qualify for a private dock?

• •Property that qualifies for a residential building permit, and that directly adjoins the public property — not separated from it by a road, a right-of-way, subdivision common area, or leased land.
• •Proof of ownership plus a surveyor's plat.
• •A minimum of 65 feet of allocated shoreline. Allocated shoreline is measured as the shortest possible lines from the adjoining private property's outer corners to the shoreline at normal pool, so a wide lot with a pinched water edge can fail the 65-foot test.
• •One dock per owner at one location, regardless of how many parcels the owner holds.
• •At least 50 feet of separation from any other dock. Some existing docks are closer than that, and in those overcrowded areas no new docks or expansions to existing ones will be permitted.

How big can a dock be on Old Hickory Lake?

• •The dock plus the moored boat or boats, including slips, may not exceed 700 square feet. The Corps reviewed that cap in 2020 and kept it, on the reasoning that large cruisers and houseboats must be moored at a commercial marina. Oversize docks permitted under earlier rules are grandfathered.
• •A slip dock may be up to 40 feet long. One section may be 8 feet wide; others are limited to 6 feet. A platform dock with no slip is capped at 160 square feet, or 280 square feet with a personal-watercraft or small-boat lift. A walkway may be up to 6 feet wide.
• •A dock may not extend more than 50 feet perpendicular from the shore, and up to 59 feet only in unusual circumstances supported by depth soundings, as an alternative to dredging. In a narrow cove the limit is 50 feet or one-third the cove width, whichever is less.
• •Floating construction only. Fixed piers, fixed walkways, and fixed docks are prohibited, docks cannot be moored to trees, and flotation must be encased and warranted for a minimum of eight years. Concrete footers are capped at 25 square feet.
• •A roof may shelter the boat but may not be used as a sun deck or storage area, and flat roofs that could serve as a sun deck or patio are no longer permitted. New enclosed boathouses are not permitted. Roof overhang beyond three feet counts toward the square footage.
• •Lifts may not be fixed with driven pilings, must be attached so they fluctuate with the dock and the water level, and count toward the square-footage cap. Mooring buoys are not permitted.
• •No side floats, diving boards, slides, playground equipment, grills, tables, or furniture. No human habitation, and no renting, leasing, or licensing of the dock or a slip. A 50-cubic-foot gear locker, which may double as a bench, is the only storage allowed.
• •Electrical work follows the National Electrical Code and is certified by the state electrical inspector, with the disconnect above flood pool and no floodlights. Solar panels have been allowed since 2020, with no wires across government property and the equipment in a locked box on the dock.
• •Plans are certified by a licensed engineer, architect, or licensed general contractor. Construction must be finished within 180 days or the permit is void, and permits will normally be issued for a five-year term.

Does the dock permit transfer when I buy?

No. This is the single most misunderstood fact in lake real estate here, and it is not ambiguous. The Shoreline Management Plan states that shoreline use permits are non-transferable, and that a new permit may be issued to a new property owner after he or she submits a completed application and the required fees, with the permit issued only after the fee is paid. Permit Condition 23 says that upon the sale or other transfer of the permitted facility, or the death of the permittee and his or her legal spouse, the permit is null and void.

There is a clock attached. Under Condition 29, the seller or the buyer notifies the Resource Manager prior to finalization of the sale, and the new owner must apply for a shoreline use permit within 14 days or remove the facility and restore the use area within 30 days from the date of ownership transfer. Put both dates on the closing calendar before you go under contract, not after.

Several things also come off the dock at the sale by rule, not by negotiation:

• •Existing stairs or other access to a dock roof must be removed, or the access permanently restricted, upon change of ownership.
• •A pre-existing enclosed boathouse may remain only while structurally sound, and when ownership changes the new permittee is required to remove the sides.
• •A lift that does not float with the dock must be removed before ownership changes to a new permittee.
• •Unused side floats and certain licensed land items, such as water pumps, come out as well.

And the part that turns a seller's deferred problem into a buyer's problem: non-compliance follows the property. Until non-compliance issues are satisfactorily resolved, the permit will not be reinstated or reissued, even if the property changes ownership. The plan puts the duty to disclose on the owner — it is the property owner's responsibility to inform potential purchasers of any restrictions imposed by the Corps due to non-compliance with permit conditions — but the consequence lands on whoever owns the house next.

What is a Corps Realtor Letter, and who can ask for one?

It is the one pre-offer document almost nobody uses, and it exists specifically for this moment. The Shoreline Management Plan describes Realtor letters as a valuable tool to inform prospective realtors or buyers of the shoreline classification adjacent to their lot, and to correct any deficiencies with the existing permit prior to sale of the property. The letters are provided to the current owner or owners, they are valid for 90 days, and they are generally issued within 14 days of a completed application. The September 2025 draft keeps all three elements unchanged.

Because only the current owner can request one, a buyer's move is to ask the seller to obtain it — ideally before the listing ever goes live, so the classification and any permit deficiencies are known to everyone up front. That is a normal ask on a lake property, and a seller who has already done it is telling you something useful.

The reason it matters this much is what the Tennessee seller's disclosure does not cover. The RF201 Residential Property Condition Disclosure, version 01/01/2026, asks about the date of the most recent survey and changes since, encroachments and easements affecting ownership, flooding, drainage, or grading problems, any requirement to maintain flood insurance, damage from flooding, zoning violations, deed restrictions, the HOA, and common areas co-owned with others. It asks nothing about dock permit status, permit compliance, shoreline classification, or where the government line runs. Those answers exist only at the Corps and on a stake survey.

What does it mean when a dock is grandfathered?

Under Public Law 97-140 as amended by §1134(d) of Public Law 99-662, permits for facilities that existed as of November 17, 1986 may not be revoked unless the dock or structure presents a hazard, the permittee fails to comply with the conditions of the permit, or the District Engineer revokes the permit when the public interest necessitates it. A grandfathered dock may be repaired or rebuilt to its original permitted shape and size, or smaller, with permission from the Resource Manager.

For a buyer that cuts both ways. An older dock that is larger than 700 square feet, or sits closer than 50 feet to a neighbor, may be entirely legal because it predates the rule — and it can never be enlarged. If it falls out of compliance and the problem is not corrected, the plan is blunt about what follows: the permit will be revoked, the dock must be removed, and another permit or outgrant will not be issued.

What can and can't happen on the Corps strip behind the lot?

• •Vegetation: a permit is needed even for understory control, and cutting trees greater than one inch in diameter at the base is prohibited. Mowing permittees may be required to maintain 24 trees per acre. No cutting is allowed in environmentally sensitive areas or on the lake's islands. Fallen trees, driftwood, and debris may be removed without approval.
• •Erosion control: the approved methods are a vegetative buffer strip, quarry-run riprap, placement of existing natural rock, and vegetative or bioengineering methods, with gabions only where those are impractical. Removing natural-rock placement from that list is one of the 2026 draft proposals, so treat it as proposed and not yet in effect. Hard seawalls are not a listed standard method.
• •Structures: stairs, walkways, footbridges, and chair lifts require a license and certified plans, and a footbridge may not extend below or cross over the 445-msl elevation.
• •Wake: no-wake designations will not be given solely to protect private docks. No-wake areas are state designations enforced by TWRA.
• •Marine railways: no new marine railways will be approved. Existing ones were granted in lieu of a shoreline use permit for a private dock and remain in lieu of a dock permit.
• •Enforcement: government representatives are allowed to cross the permittee's property to inspect and, if necessary, to remove an unauthorized structure, and the permittee reimburses the removal cost within 90 days.

Does a lake community with deeded access come with a boat slip?

Usually not the way buyers assume. The community association, not the individual members, owns a community dock, and one can exist only on Limited Development shoreline that is allocated for docks. For a multiple-family development the Corps permits a single facility of up to twenty boat slips, at one slip per sixty-five linear feet of allocated shoreline suitable for placement of individual private docks. The applicant must be a legally incorporated non-profit association, and the request qualifies only after the development is substantially complete, defined as twenty-five percent of the units owner-occupied. The facility must be for the legitimate recreational use of actual residents and not a speculative venture by developers to enhance marketability. Near campgrounds, marinas, and ski areas, only a community dock will be permitted at all. Individual slips cannot be rented, leased, or licensed.

Do the arithmetic before you fall for a brochure. Twenty slips is the ceiling for a facility, and one slip per 65 feet of allocated shoreline is the rate, so in most lake communities the number of slips is far smaller than the number of homes. The September 2025 draft would narrow it further: it adds language that the number of slips will never exceed the number of residential lots with 10 feet of private property adjacent to common area with allocated shoreline directly fronting a Limited Development Area allocated for private docks. That sentence is not in the 2020 text — it is the proposed minimum-frontage rule, and it is not in effect yet.

How much does Old Hickory Lake drop in winter?

About a foot. This is the number that surprises people coming from deep tributary reservoirs, where the winter drawdown can be dozens of feet. Old Hickory is a run-of-the-river project that experiences minimal annual pool fluctuations. Its power pool was designed for fluctuation between elevation 442 and 445, but because of navigation and recreation hazards in the lower range, the pool is operated in the upper portion, typically fluctuating between 444 and 445.5 at the dam. TWRA states it in plain numbers: full pool is 445 feet mean sea level and winter pool is 444 feet mean sea level.

Maintenance drawdowns happen on top of that, and they are periodic rather than annual, requested by the Resource Manager, and shallow. The dated example: beginning October 30, 2023, the Corps lowered the lake from about 445 to 443 feet, held it between 443 and 443.5 — roughly one to two feet lower than normal pool — reached target on November 3, held through November 19, and refilled between November 20 and 27. The Resource Manager framed it as an opportunity for private property owners to take advantage of a lower lake level to perform maintenance on their docks or remove debris from the shoreline. No comparable 2024 or 2025 drawdown announcement exists, so do not plan around a fixed annual schedule.

Where that foot actually shows up is the coves. Surface area is about 22,500 acres at 445 and about 19,550 acres at 442, and the roughly 3,000 acres in between are shallow cove margin, not main channel. The Corps' own eligibility criterion is the practical version of the same physics: a dock must be able to float at normal pool elevation 445, so a silted cove that will not float a dock at 445 will not get a permit. When you tour, look at the cove, not the channel.

What are the flood facts for an Old Hickory Lake property?

State them as facts about elevation and zone, and get them from the map rather than from anyone's opinion. Old Hickory was authorized as a multiple-purpose project by the Flood Control Act of 1938 and reauthorized by the Rivers and Harbors Act of 1946, and its primary authorized purposes are a navigable channel on the Cumberland and hydroelectric power, with recreation, fish and wildlife, and water quality secondary. The Master Plan is specific about what the project does not have: Old Hickory was not designed with flood control storage, though it does have a small amount of space dedicated to flood surcharge storage, between elevation 445 and 450, which replaces the natural river-valley storage lost when the lake was impounded. The Corps notes those two terms are often confused. The maximum observed elevation is 451.54, in 2010.

For a specific parcel, the numbers that matter are FEMA's. The Sumner County Flood Insurance Study lists Old Hickory Lake at East Camp Creek, in feet NAVD88, at 450.2 for the 10-percent-annual-chance event, 451.1 for the 2 percent, 451.4 for the 1 percent, and 452.8 for the 0.2 percent. For the Cumberland River between miles 216.14 and 248.44, the floodway shown on the FIRM was designated using the shorelines, because the dam creates an impoundment effect upstream. NFIP community numbers are 470185 for Gallatin and 470186 for Hendersonville. One datum caution: converting NAVD88 to NGVD29 adds 0.23 feet, and the Corps' 451.54 observed elevation is not stated in NAVD88, so the Corps figure and FEMA's 1-percent figure are not the same frame of reference and should not be lined up as if they were.

The mechanics are straightforward. A federally backed mortgage on a structure in a Special Flood Hazard Area triggers mandatory flood insurance; Zone X is outside the SFHA. Look the parcel up at the FEMA Flood Map Service Center, msc.fema.gov, and get an actual quote from a licensed insurance agent — premiums are parcel-specific and the ranges circulating online are estimates, not quotes. RF201 items 10 through 12 ask the seller about flooding or drainage problems, any requirement to maintain flood insurance, and damage from flooding. We will pull the map for any property you are serious about; we will not guess at a premium.

What is changing in the 2026 shoreline plan update?

The operative document is the 2020 Old Hickory Lake Shoreline Management Plan, Appendix M to the Operational Management Plan, approved by the Great Lakes and Ohio River Division on December 7, 2020 under the authority of 36 CFR 327.30 and ER 1130-2-406. It replaced the 2014 plan, and that review determined the locations where private docks may be approved.

A draft plan with tracked changes dated September 2025 has been posted. Public workshops were held January 13, 2026 at Mt. Juliet Middle School and January 14, 2026 at Gallatin High School, with written comments due February 13, 2026. Named proposals include establishing a minimum frontage for residential lots adjacent to common area to qualify for a community dock slip, and removing natural rock placement as a means of approved shoreline erosion control. As of September 2, 2026 no approval announcement has been published, so the 2020 plan governs. The previous cycle ran roughly fourteen months from workshops to approval, which is the only honest guide to timing — the Corps has not published a date.

What the draft does not change is as useful as what it does. The 33/17 shoreline allocation split, the 14-day and 30-day transfer clock with its non-transferable permit, and the Realtor Letter's 14-day issuance and 90-day validity are identical in the draft text.

Where do you verify any of this?

• •The Old Hickory Lake Resource Manager's Office, No. 5 Power Plant Road, Hendersonville, TN 37075 — 615-822-4846, OldHickoryLake@usace.army.mil. The official Shoreline Allocation Map is kept there. Note that the Old Hickory Lake Visitor Center has been closed to the public since the December 9, 2023 tornado and business is handled by appointment, so do not plan on walking in.
• •The Sumner County Assessor of Property GIS, at 355 N Belvedere Drive in Gallatin, for parcel lines. Parcel mapping is not the Corps line and does not substitute for a stake survey.
• •The FEMA Flood Map Service Center at msc.fema.gov for the parcel's flood zone, plus a licensed insurance agent for an actual premium.
• •The plan documents themselves: the 2020 Shoreline Management Plan, the September 2025 tracked-changes draft, and the 2016 Old Hickory Lake Master Plan are published in the Corps' digital document collection at usace.contentdm.oclc.org.

What do lake buyers get wrong about docks?

• •Assuming lakefront means the lot touches the water. Nearly everywhere on Old Hickory, a strip of United States land sits between the property line and the lake.
• •Assuming half the shoreline can have a dock. Half is Limited Development, but only the roughly one-third allocated for private docks and mowing permits one; the other 17 percent is mowing only.
• •Assuming the deed stops at the water's edge or at a readable contour. The boundary is a surveyed fee line on dry land, and a new permit can require a stake survey at the owner's expense.
• •Assuming the permit conveys at closing. It is non-transferable and void at the sale, and the new owner has 14 days to apply or 30 days to remove the dock.
• •Assuming an existing dock is permitted and compliant. Uncorrected non-compliance blocks reissuance to the buyer, no matter who created it.
• •Assuming a lake community with deeded access means a slip. Twenty slips is the ceiling for a community facility, at one slip per 65 feet of allocated shoreline.
• •Touring in July and imagining February as a different lake. It is about a foot — and the foot lands in the coves, not on the channel.

How our team works an Old Hickory lake purchase

Docks and shorelines are exactly the kind of specialized due diligence that gets skipped. Before you write an offer we confirm the shoreline classification and the permit's current standing with the Corps, ask the seller to request a Realtor Letter, measure the existing dock against the 700-square-foot cap and the 65-foot and 50-foot rules, pull the FEMA map for the parcel, and put the 14-day and 30-day transfer deadlines on the closing calendar. Then we walk the line with you and look for the blazes and posts, because the property you are buying ends where the government's begins.

And we put the relationship in writing: every buyer agreement includes a 24-hour kickout, so written notice releases you within 24 hours if we are not earning it. We would rather earn the lake house every week than lock you in for six months.
