Lake Martin vs. Other Alabama Lakes: How Smith Lake and Logan Martin Compare

Updated October 2026

There's no single best lake in Alabama to buy a house on. There's the best lake for you. Lake Martin is the biggest of the three Alabama Power lakes I compare here, Smith Lake is by far the deepest, and Logan Martin is the long, narrow one on the Coosa River. Which one fits comes down to your budget, how you boat, how far you'll drive, and whether this is a weekend place or your full-time home.

I live and work in Auburn, and Lake Martin is a big part of my world. If Lake Martin is already your front-runner, my guide to buying a lake house on Lake Martin walks through the whole process.

The Bottom Line

Lake Martin covers 41,150 acres with 880 miles of shoreline, per Alabama Power. That's about 1.5 times Smith Lake's acreage, by my math.
Smith Lake is smaller at 27,316 acres but reaches 264 feet deep at the dam, compared with 155 feet at Lake Martin.
Logan Martin is 48.5 miles long with 275 miles of shoreline and 69 feet of depth at the dam.
Martin and Smith are both storage lakes, so their levels drop in fall and winter and refill for summer.
A public monthly market report covers the Lake Martin Area. Comparing prices lake to lake works best with specific sold homes.
Whether the house is your primary home or a second home changes how Alabama assesses it for property tax.

Lake Martin, Smith Lake, and Logan Martin at a glance

Here's how the three lakes line up on Alabama Power's own lake pages, current as of October 22, 2026.

Lake	Surface area (acres)	Shoreline (miles)	Length (miles)	Max depth at dam (feet)	Listed elevation (feet)
Lake Martin	41,150	880	31	155	491
Smith Lake	27,316	713	35	264	510
Logan Martin	15,263	275	48.5	69	465

A little history helps, too. Martin Dam went into service in 1926. Smith Lake's dam went into service in 1961 and stands 300 feet tall. Alabama Power lists a watershed of 3,000 square miles draining into Lake Martin and 944 square miles draining into Smith Lake.

Size and shoreline: how much lake do you want?

Lake Martin's 880 miles of shoreline is the headline number. In practice, all that shoreline spreads out into a lot of coves and creek arms. In my experience, that's what makes the lake feel so different from one side to the other. A home on a quiet slough and a home on open main-channel water can feel like two different lakes.

Smith Lake's 713 miles of shoreline is packed into less surface area, wrapping around a long, deep reservoir. Logan Martin stretches 48.5 miles but covers only 15,263 acres, so it reads more like a wide river than a big open bowl.

My read on what this means for you:

If you want room to roam by boat, Lake Martin's size gives you a lot of water to explore.
If you care more about a specific cove than the whole lake, size matters less than the exact lot.
On any of the three, the cove, the view, and the water in front of the dock matter more than the lake's total acreage.

When you're ready to narrow down where on Lake Martin, my rundown of the best Lake Martin communities is a good next step.

Depth and water levels: the question to ask before you fall in love

Depth is where Smith Lake stands apart. It reaches 264 feet at the dam, versus 155 feet at Lake Martin and 69 feet at Logan Martin, per Alabama Power.

Water level matters even more for a buyer. Alabama Power runs both Lake Martin and Smith Lake as storage lakes. That means the water is drawn down in fall and winter and refilled for summer. A dock that floats in deep water in July can sit much closer to the bottom in January.

Here's a snapshot. On October 22, 2026, Alabama Power's lake pages showed Lake Martin about 3.7 feet below its listed 491-foot elevation. Smith Lake was about 11.1 feet below its listed 510-foot elevation, by my math. That's one day's reading, not a target level, and it moves all season.

What I tell buyers on every lake:

Ask what the water depth is at the end of the dock in winter, not just in summer.
If you can, see the property during the drawdown before you close.
Look at how the shoreline slopes. A gentle slope can leave a dock high and dry sooner than a steep one.

Prices and market pace: what the public numbers cover

The Alabama Center for Real Estate at the University of Alabama publishes a monthly Lake Martin Area report, and it counts waterfront and non-waterfront homes together. In May 2026, the most recent release I'm citing here, the Lake Martin Area had 79 closed residential sales and a median sales price of $499,000, up 15.0% from a year earlier. Homes sold that month averaged 109 days on the market. There were 506 listings, and the report put supply at 6.4 months at the current sales pace.

Two things to keep in mind with that report. First, it mixes lake homes with off-water homes, so it isn't a waterfront price. Second, one month is one month. It isn't a forecast.

The ACRE reports reviewed here did not provide a comparable Smith Lake series. So if you're weighing Smith against Martin on price, the better way to do it is cove by cove, with recent sold homes that match what you want. That's work I'm happy to do with you on the Lake Martin side.

If you're thinking long term, I go deeper on that in is a Lake Martin house a good investment.

Docks, shoreline work, and the parcel itself

On Alabama Power lakes, shoreline work like docks, boathouses, and seawalls goes through Alabama Power's lakeshore permit process. Each lake has its own guidelines, so read the current ones for the lake you're buying on. Don't assume one lake's rules carry over to another.

My checklist for any lake lot, on any of these lakes:

Get a copy of the deed and survey early, and see exactly where the property line meets the water.
Ask whether the existing dock and any seawall were permitted.
Check the parcel's flood zone on FEMA's map before you talk insurance.
Confirm the septic permit and what the system was approved for, especially if you plan to add bedrooms.
Verify internet service, drive time, and the nearest hospital for the specific address, not the lake in general.

Full-time home or second home: taxes and rentals

How you'll use the house changes the math, on any lake.

Property tax classification. The Alabama Department of Revenue assesses single-family owner-occupied residential property at 10% of value, as Class III. Property not otherwise classified is Class II, assessed at 20%. A homestead is a single-family owner-occupied home and its land, up to 160 acres. Before you budget for a second home, ask the county revenue commissioner how that house will be classified. This isn't tax advice, so loop in your tax pro, too.

If you're planning to live at the lake year-round, my post on moving to Lake Martin full time covers what that day-to-day looks like.

Short-term rentals. Alabama's lodgings tax applies to rooms or accommodations rented to transients for periods of less than 180 days of continuous occupation, according to the Alabama Department of Revenue. If a booking platform collects and pays all the state and local lodgings taxes for you, you don't need separate accounts. If you also book guests directly, you do. The state doesn't run every county or city lodgings tax, so you'll need to check with each local government too.

Local rules change. Confirm current requirements with the city or county before relying on anything here. This is not legal advice.

Selling an Auburn-area home to buy at the lake

If you're selling a home in Auburn or Opelika to buy at the lake, your home-base market matters to the plan. These figures cover LCAR All Areas, a reporting cut that includes Auburn, Opelika, and the rest of Lee County and excludes the Outside Lee Co area. It is not a lake-specific dataset.

Per the Lee County Association of REALTORS®, the median sold price for residential homes in LCAR All Areas was $425,000 in September 2026, compared with $400,000 in September 2025. Sales rose to 189 homes from 161 a year earlier. Homes took longer to sell, averaging 66 days on the market versus 54 days in September 2025.

Median sold price, LCAR All Areas residential, September 2025 vs. September 2026. Median sold price: $400,000 in September 2025, $425,000 in September 2026

My read: if your Auburn-area sale is funding the lake purchase, build in time for that sale. Timing both moves together is where a plan really pays off. Before you list, it's also worth a look at capital gains tax when you sell in Alabama.

Which Alabama lake fits you?

This is my opinion, built from the facts above and a lot of time on the water. It isn't a ranking.

You want the most lake to explore and you're based in East Alabama. For most of my Auburn and Opelika clients, Lake Martin is the closer of these lakes, and its size gives you plenty of water.
Deep water is at the top of your list. Smith Lake's depth at the dam is in a different league from the other two.
You want a long, river-style lake. Logan Martin's 48.5-mile length gives it that feel.
You're on a firm budget. Don't pick the lake first. Pick the price, then compare specific homes on each lake that fit it.
You plan to rent it out sometimes. Check the local rental rules and lodgings tax setup for that exact address before you fall for the view.
