Mammoth Spring In North Central Arkansas

The city of Mammoth Spring is nestled along the Arkansas/Missouri border in North Central Arkansas. We wanted to take you along as we traveled to see the spring from which the city got its name.

We visited Mammoth Spring State Park to view the spring. This is a huge spring that bubbles up from underground at the north end of the park. According to the signs posted in the park, the spring emits an average flow of 9.78 million gallons of water per hour. So the average amount of water flowing from this underground spring is about 235 million gallons daily.

All of this water flows from underground and across two outflow areas into the lake created by a dam on the park’s south end. The dam was used to redirect the flow of water through a hydroelectric generator in the early part of the 20th century.

As you read the article you can click on any of the photos to see a larger version in your browser. Our tour started directly behind the visitor center. This is where you can see a bridge support from the old bridge that connected the train station to the city of Mammoth Spring. The original bridge was made of wood. It was replaced by a steel bridge in later years. The steel bridge was privately owned and was sold for scrap back in the 1960s. In the photo, you can see that freight trains still pass the train station, which also contains a museum.

A Piece Of History

As you continue north along the path to the spring you will see an old artillery piece to your left. Known locally as the “Big Gun”, the sign placed with the gun tells about its history. It is fired at dawn and dusk each day during the annual week-long celebration known as the “Reunion of the Blue and Gray”. This celebration is held annually in July.

After you view the “Big Gun” continue north along the walking path and you’ll come to Mammoth Spring. If you’ve been to other small natural springs you’ll marvel at the amount of water that comes to the surface here from underground. These are some photos from the first outflow that you encounter along the path.

There also is an abundance of wildlife in the park. Below is a photo of a mother wood duck and her ducklings. She and her brood decided to rest in the shade just a few feet from where we were shooting.

Continue along the path for a short distance and you will come to another bridge that gives you a good view of the second outflow from the Mammoth Spring. The roaring water gives you an idea of how much water is emitted from the spring.

Be sure and take the path to your left up to the raised viewing platform. From there you can get a sense of how large Mammoth Spring truly is.

Train Station and Museum

You can follow the trail back down the way you came to the walkway and continue around the lake. This will take you to the train station and museum that you could see across the lake from the visitor’s center. We found that the museum was closed on Monday so we were unable to get any photos from inside.

Dam and Hydroelectric Plant

The trail around the lake is a loop trail. As you continue from the train station you will arrive at the dam and the old hydroelectric power plant. The dam was built in 1888 to provide water power to drive machinery for local industry. The rights to the dam were bought in 1925 by the Arkansas-Missouri Power Company. In 1927 the hydroelectric plant was built. It provided electricity to the area until 1972.

As you can probably see from the photo above from this point it is only a short walk back to the parking area. Before you leave be sure to visit the friendly folks in the Visitor Center and pick up a drink, snack, or souvenir.
