Have you ever typed “lake texoma” in a message and wondered if it looks right? You are not alone. Many people are not sure how to write place names, and lakes can be tricky. The short answer is easy: Lake Texoma should be capitalized. Both words need a capital letter, every time you use the full name.
The Quick Answer
Write it like this: Lake Texoma.
Do not write it like this:
- lake Texoma
- Lake texoma
- lake texoma
- LAKE TEXOMA (unless the whole line is in capital letters, such as a sign or a headline style)
“Lake Texoma” is the official name of one specific place. Because it is a name, it is a proper noun. Proper nouns always start with a capital letter.
What Is a Proper Noun?
A noun is a word for a person, place, or thing. There are two main kinds:
- Common nouns are general words. “Lake,” “river,” “mountain,” and “city” are all common nouns. They can describe thousands of places.
- Proper nouns are the special names of one person, place, or thing. “Lake Michigan,” “Mount Everest,” and “Lake Texoma” are proper nouns.
One writing guide explains it in a simple way. You can talk about a lake in the middle of the country, or you can say “Lake Michigan,” which tells the reader exactly which lake you mean. That is the power of a proper noun. It points to one thing and nothing else.
So when someone writes “Lake Texoma,” they are not talking about any lake. They are talking about the large lake on the border of Texas and Oklahoma.
Why Both Words Get a Capital Letter
You may ask: “Texoma” is clearly the special name. Why does “Lake” need a capital letter too?
The reason is that “Lake” is part of the official name. Style guides have a clear rule for this. The U.S. Government Publishing Office style manual says that a common noun that forms an essential part of a proper name is capitalized. Its example is “Lake of the Woods.” When you use the word alone, as in “the lake,” it is not capitalized.
A style guide from the University of Wisconsin says the same thing. It gives “Lake Mendota” as an example of a name with capitals, and “the lake” as the form with a small letter when it stands alone. The guide also points to The Chicago Manual of Style as a source for these rules.
Here is how that rule works for our lake:
| How you write it | Is it correct? | Why |
|---|---|---|
| Lake Texoma | Yes | The full official name |
| the lake | Yes | A general, short reference |
| Texoma | Yes | The special part of the name, used as a short form |
| lake Texoma | No | “Lake” is part of the name |
| Lake texoma | No | “Texoma” is the main name part |
Real Examples You Can Copy
Seeing the rule in real sentences makes it easier to remember.
Wrong: We spent the weekend at lake texoma. Right: We spent the weekend at Lake Texoma.
Wrong: The fishing guide meets visitors at lake Texoma at sunrise. Right: The fishing guide meets visitors at Lake Texoma at sunrise.
Wrong: Have you seen a map of lake texoma? Right: Have you seen a map of Lake Texoma?
Now look at a sentence that uses both the full name and a short reference:
Lake Texoma is popular with boaters. On summer weekends, the lake gets very busy.
The first sentence uses the full name, so it has capital letters. The second sentence says “the lake” in a general way, so it uses a small letter. This is exactly how the style guides want you to write it.
When Do You Use a Small Letter?
You only use a small “lake” when you are not using the official name. Here are the main cases:
- When you say “the lake” alone. “We drove to the lake after lunch.” Here, the reader already knows which lake you mean.
- When you talk about lakes in general. “Many lakes in Texas are man-made.”
- When you describe a lake without naming it. “It is a large reservoir on the state border.”
If you write the full name, use capitals. If you use a general word, use a small letter. That one idea solves almost every case.
Other Names Connected to the Lake
The lake’s name appears in many other names. Most of them also need capital letters because they are proper names too.
- Lake Texoma State Park is the name of a state park in Oklahoma.
- Lake Texoma’s shoreline: add ‘s for a possessive, and keep both capitals.
- Denison Dam is also called Lake Texoma Dam.
- Texoma by itself is often used for the whole region around the lake. It is still capitalized.
What about two lakes in one sentence? The University of Wisconsin guide says that common words become capitalized in plural names, such as “Langdon and State Streets.” Following that same idea, you would write “Lakes Michigan and Huron.” For two separate full names, the safest and clearest way is simply to write both in full: “Lake Texoma and Lake Murray.”
Common Mistakes to Watch For
Even careful writers make small mistakes with place names. Here are the ones that appear most often.
1. Writing it in lowercase when typing fast. On a phone, it is easy to skip the capital letter. A quick check before you send an email or post a comment helps.
2. Capitalizing only one word. “Lake texoma” and “lake Texoma” are both wrong. If one word has a capital letter, the other one needs it too.
3. Capitalizing “the lake” every time. Some people think respect for a place means using capitals everywhere. But “the lake” on its own is a common noun. Keep the capital letters for the real name.
4. Capitalizing “the” in the middle of a sentence. You write “the Lake Texoma area” with a small “the” unless it starts the sentence.
5. Copying the lowercase spelling from social media. Many online posts are written quickly and casually. Do not use them as a guide for your own writing.
Why Capital Letters Matter in Your Writing
You might think a capital letter is a very small detail. But it does real work.
- It shows you know the place. A correct name tells the reader that you care about the details.
- It avoids confusion. A capital letter shows that you mean the exact lake, not “a lake called Texoma.”
- It looks professional. If you write a blog, a travel page, a school paper, or a business website, correct names make your work look careful and trustworthy.
- It helps people find you. Many people search for the name with proper capitals, and tidy writing is easier for readers to understand.
A Closer Look at Lake Texoma
Now that the rule is clear, it helps to know a little about the lake. Places with a long history often have names worth getting right.
Where It Is
Lake Texoma sits on the border between Oklahoma and Texas. It is formed by Denison Dam on the Red River. The lake is at the point where the Red River and the Washita River meet. According to Wikipedia, it covers about 89,000 acres, which is around 139 square miles.
The name “Texoma” blends the words “Texas” and “Oklahoma,” the two states that share the lake. Congress approved a law on September 30, 1944, that gave the lake this name. Public records of that law still exist today.
A Big Lake with Many Visitors
Lake Texoma is one of the largest reservoirs in the United States. It is the 12th-largest lake managed by the U.S. Army Corps of Engineers, and the largest in the Corps’ Tulsa District. It is also the most popular one there, with about 6 million visits each year.
Part of that popularity comes from location. The lake is about an hour’s drive north of the Dallas and Fort Worth area, so many families can visit for a day or a weekend.
Fun Things to Do
There is a lot to do around the lake. Wikipedia lists two state parks, 54 parks run by the Army Corps of Engineers, 12 marinas, and 26 resorts. People enjoy boating, sailing, water skiing, wind surfing, and camping. The lake is also known for fishing. Two state parks sit on its shores: Lake Texoma State Park in Oklahoma and Eisenhower State Park in Texas.
A Rare Fish in Salty Water
Here is a fact that surprises many people. The Red River that feeds the lake is salty. The salt comes from deposits left behind by an old sea that existed in this area about 250 million years ago, as Wikipedia explains. Because of this, striped bass, a saltwater fish, can live in the lake. Lake Texoma has the only self-sustaining population of striped bass in Texas.
How the Lake Was Built
The story of the lake begins before World War II. The Flood Control Act of 1938 gave money for the dam. The main goals were flood control, water supply, and making electricity. Sam Rayburn, a well-known congressman from Texas, helped push the project forward in the early 1930s.
Work on the dam continued during the war. German prisoners of war helped with some of the work, such as clearing trees and light building jobs. The dam was finished in January 1944 and cost about 54 million dollars at the time. Recreation was not officially added as a goal of the project until 1988, even though people had been enjoying the lake for many years.
The Texas county historical marker near Denison also tells part of the story. It says the lake covers about 93,080 acres in normal conditions and has a shoreline of about 550 miles. It also notes that building the lake meant moving railroads, roads, utilities, and cemeteries, and that the old town site of Preston went under the water.
A Short Time as a National Park Service Area
In 1946, the Corps of Engineers gave the Park Service responsibility for recreation at the lake. For a little over three years, it was a unit of the National Park System. In 1949, the Park Service returned it to the Corps of Engineers, and the Corps has managed it since.
A Record Flood Year
In 2015, heavy rain pushed the lake higher than ever before. Wikipedia reports that the lake reached a record level of 645.72 feet on June 1, 2015. The top of Denison Dam stands at 670 feet. That same month, the draining water formed a large whirlpool near the dam that was seen around the world.
Simple Tips to Remember the Rule
You do not need to memorize a long list. These small habits are enough:
- Think “name or not.” If you are using the full name, use capitals on every main word.
- Compare it with other lakes. You would never write “lake michigan” or “lake superior,” so do not write “lake texoma.”
- Check your short forms. “The lake” alone gets a small letter. “Texoma” alone keeps its capital.
- Use your spell checker, but do not trust it fully. Some tools do not catch place names.
- When unsure, check a style guide or a trusted dictionary. The Chicago Manual of Style and the GPO style manual are good places to look.
Frequently Asked Questions
Is it Lake Texoma or lake Texoma?
It is Lake Texoma. “Lake” is part of the official name, so both words need a capital letter. Style guides, including the GPO style manual, say that a common word that is an essential part of a proper name should be capitalized. A small “lake” is fine only when you use it alone, such as “the lake.”
Should I capitalize “the lake” when I talk about Lake Texoma?
No. When you write “the lake” by itself, it is a common noun and takes a small letter. For example: “Lake Texoma is huge. The lake covers about 89,000 acres.” The first sentence uses the full name, and the second uses a short reference, so only the first one has capital letters.
Why is “Texoma” capitalized?
“Texoma” is the special name of the lake and of the region around it. It is a blend of “Texas” and “Oklahoma,” and it works as a proper noun. That is why it is always written with a capital T, whether you write “Lake Texoma,” “Texoma,” or “the Texoma area.”
