Who Owns Your Lake?

Who owns your lake? And what kind of lake regulations could the answer mean for you as a homeowner? This question doesn’t even occur to most people. But if you are considering buying a lake home, this is something you absolutely, positively need to know.

Contrary to popular belief, lakes are not undesignated public land. They are typically owned by the government or private entities. Each lays down its own set of rules and guidelines for homeowners. When shopping for a lake home, you can save a lot of stress by finding out who owns your lake, and the rules they have.

Most large, developed lakes in the United States are owned or maintained by utility companies or the United States Army Corps of Engineers. They may also own parts, or all, of the shoreline. Homeowners along the shoreline may own their land outright, or have it in a long-term lease.

Do your homework, and always read the fine print! Here is a play-by-play on the most common types of entities that control lakes in the United States.

Utility Companies

Many of the larger lakes in the United States feed hydropower dams that generate electricity. According to the Federal Energy Regulatory Commission, there are currently more than 1,700 of these dams in the United States.

Famous hydropower lakes include Lake Mead in Arizona/Nevada, the Sam Rayburn Reservoir in Texas, and Clarks Hill Lake in Georgia/South Carolina.

These lakes are often, but not always, owned by the utility company that operates the dam. The company oftentimes owns a portion of the shoreline, as well, or retains property rights along the shoreline.

Lake regulations on these properties typically focus on construction and shoreline maintenance. Some common types of regulations include:

  • Homeowners may need permits for new construction or improvements
  • Limits and material standards for dock construction
  • Landscaping, erosion control and seawall construction guidelines
  • Water usage for utilities (especially during drought conditions)
  • Warning systems, safety precautions and “off-limits” areas near the dam itself

Lakes that feed hydroelectric dams will often rise and fall with the seasons, as energy usage fluctuates.

Check with the utility company to check on the lake level. For example, the Tennessee Valley Authority maintains a website to let visitors check on lake levels and planned water releases.

United States Army Corps of Engineers

The US Army Corps of Engineers governs more than 450 lakes in 43 states.

They manage these for flood control, recreation, preserving natural wildlife and recreation. They manage many of the hydropower lakes, as well.

On these lakes, some, or all, of the homeowners’ land may be owned by the Army Corps of Engineers, and leased to the homeowners. Leases can range from 20 to 99 years.

Take note: in these cases, mortgage lenders will never approve a mortgage longer than the lease. For example, banks will never approve a 30-year mortgage for property on land with a 25-year lease.

Here are some common lake regulations for Army Corps of Engineers lakes:

  • Serious restrictions on any portion of the property designated “public land.” This includes fence construction, roads, landscaping, gardening, etc.
  • Boat and dock size limits
  • “Off limits” areas near the dam or other utilities
  • Rules against destruction of wildlife habitat

Part of the property may be designated as “flowage easement land.”

Agencies keep this land, usually defined as a certain distance from the shoreline, clear for flood control. It can be privately owned, but has certain restrictions in order to guarantee the flow of water during flood conditions.

Homeowners can typically use flowage easement land as they see fit, with three common exceptions:

  • No structures for human dwelling, such as guest houses
  • Installation of septic tanks, sewer lines or other underground utilities is severely limited
  • Landowners cannot build fences across flowage easement land; they can, however, build them up to the edge of it.

Homeowner’s Associations

Homeowner’s Associations control many of the smaller, private lakes in the United States.

These associations have very different concerns than the federal government or utility companies.

Their lakes don’t serve a major public interest. Rather, people use these lakes primarily for their beauty and personal enjoyment.

Because of this, regulations focus more on the lake’s aesthetics and culture. Homeowners often have more legal rights.

At the same time, they can run into problems if any improvements or usage don’t fit within the rules of the homeowner’s association.

Common lake regulations by homeowner’s associations include:

  • Association membership fees
  • Limits on boat or dock size
  • Limits on boat speed and other water activities
  • Approval required for new construction, especially those facing the water
  • Standards for upkeep, such as dock repair, landscaping and shoreline maintenance

Do Your Homework on Lake Regulations

Each lake is different.

Even if you have spent years visiting a lake, chances are you don’t know all the aspects of owning property there. Always do your homework before making an offer!

This is one reason to work with an agent who specialized in lake property, especially on your lake, when shopping for a lake home.

Real estate agents who specialize in lake property know their lake’s quirks, and can help you find the home of your dreams without all the headaches.

Biggest Dams in the United States

There are more than 90,000 dams in the United States, according to the American Society of Civil Engineers. So what are the biggest dams, and which one is the largest?

That’s a simple question with a complicated answer.

Do we mean the tallest? The longest? The one that generates the most electricity, or the one that holds back the most water?

Here’s an answer to all four of those. These behemoths are wonders of human engineering, each of them with its own unique history.

The Tallest: Oroville Dam

Location: Oroville, California
Impounds: Feather River
Creates: Lake Oroville
Height: 770.5 feet
Length: 6,920 feet (1.31 miles)
Construction: 1961-1968

At just over 770 feet tall, the Oroville Dam was built in the 1960s by the California Department of Water Resources. The state built several dams in that period to water California’s rapidly expanding farm economy.

The Oroville Dam diverts the Feather River into the California Aqueduct, creating a major water supply for the San Joaquin Valley.

At the same time, it also offers flood protection to large parts of California. The embankment dam prevented an estimated $1.3 billion worth of flood damage between 1987 and 1999.

Additionally, this dam also powers the underground Edward Hyatt Pump-Generating Plant.

This plant works alongside two off-stream reservoirs west of Oroville to form the Oroville-Thermalito Complex. Working together, the plants generate more than 2.8 billion kilowatt-hours of energy per year.

The Oroville Dam made headlines in February 2017, when intense flooding eroded the dam’s main and emergency spillways.

This erosion threatened the dam’s main wall and could have become a serious danger to nearby residents. For safety’s sake, the State of California evacuated 188,000 people for nearly six weeks as crews raced to repair the damage.

The repaired spillway was reopened in early April 2019.

The Longest: Cochiti Dam

Location: Cochiti Pueblo, New Mexico
Impounds: Rio Grande River
Creates: Cochiti Lake
Height: 251 feet
Length: 29,040 feet (5.5 miles)
Construction: 1965-1973

Though one of the biggest dams in length, the Cochiti Dam is one of the shortest in height. Surprisingly, it isn’t even on most lists of the largest dams, because of its height of only 251 feet.

However, it is one of the 10 largest earthen dams in the United States, and for good reason.

The Cochiti Dam stretches more than five miles across! It contains more than 65 million cubic feet of earth and rock and it is the eleventh largest earth-fill dam in the world.

Engineers designed the dam as a flood control mechanism, to limit the effects of heavy runoff on the surrounding area.

It was authorized under the Flood Control Act of 1960, and construction lasted from 1965 to 1973.

The resulting Cochiti Lake has a permanent recreation pool, with an intermittent pond in the arm of the Santa Fe River. The remaining capacity of the reservoir, about 672 million cubic meters, is reserved for flood and sediment control.

The Largest by Lake Volume: Hoover Dam

Location: Clark County, Nevada / Mohave County, Arizona
Impounds: Colorado River
Creates: Lake Mead
Height: 726 feet
Length: 1,244 feet (0.24 miles)
Construction: 1931-1936

Possibly the most famous dam in the United States, the Hoover Dam sits at the border between Arizona and Nevada. Its curved face stretches between the walls of the Black Canyon and holds back the Colorado River to form Lake Mead.

At the time of its construction, the Hoover Dam was the largest concrete structure built. The dam stands 1,244 feet long, 726 feet high, and 660 feet thick at its base.

Its construction required an incredible 3.25 million cubic yards of concrete. Just for perspective, that’s enough to pave a 16-foot-wide highway from San Francisco to New York City!

From the very beginning, designers kept long-term strength at the forefront of their minds.

They brought many innovative solutions to bear. These include the dam’s characteristic convex shape and a nonreactive concrete aggregate that won’t deteriorate due to alkali-silica reaction over the years.

As a result, the Hoover Dam easily withstands forces on a geologic scale.

It needs to be, too. It holds back Lake Mead, the largest man-made reservoir in the United States by water capacity.

The lake is 112 miles long when full, and has 759 miles of shoreline, with a maximum depth of 532 feet. It provides water to nearly 20 million people in Arizona, California, and Nevada.

The Most Powerful: Grand Coulee Dam

Location: Grant / Okanogan counties, Washington
Impounds: Columbia River
Creates: Franklin Delano Roosevelt Lake
Height: 550 feet
Length: 5,223 feet (0.99 miles)
Construction: 1933-1942

The Grand Coulee Dam is a gravity dam located on the Columbia River in Washington State.

The U.S. Bureau of Reclamation designed the dam in the 1930s for the primary purposes of flood control and irrigation. Today, it works as the largest electric power-producing facility in the country.

Construction began on the Grand Coulee Dam in 1933. For cost reasons, the builders originally designed the dam, and went through the first year of construction, as a 290 foot “low dam.”

After a visit from President Franklin D. Roosevelt though, the federal government gave funding for a larger dam. Incredibly, the engineers successfully transitioned to a 590 foot “high dam” design during construction!

Of course, the dam’s power plant has been upgraded several times over the years.

First, with the onset of World War II, power generation became a national priority. Then, in the postwar housing and economic boom.

Most recently, in 1973, the government added a third power plant to the dam, with six generating units.

Today, Grand Coulee Dam supports four different powerhouses containing 33 hydroelectric generators.

They generate, on average, 21 billion kilowatt-hours (KWh) per year. That’s enough to power 2.3 million households for a year!
