Tongue River Reservoir State Park

Tongue River Reservoir State Park

Tongue River Reservoir State Park

Tongue River Reservoir State Park is located near the southeastern border of Montana, just 10 minutes outside of Decker.

A 265-mile-long tributary of the Yellowstone River, “the Tongue” (as it is called locally) starts in Wyoming and runs through Montana.

The park features a 12-mile long reservoir set in the scenic prairie and bluff lands of southeastern Montana, which is characterized by the striking contrast of red shale and juniper canyons. Due to the rareness of large bodies of water like this in this part of the state, the park can see up to 50,000 visitors a year.

81 reservable campsites with electric hookups, and 27 of those are double occupancy with two electric hook-ups. There are also 80 non-reservable, non-electric sites!

At 12 miles long, the reservoir makes for excellent fishing any time of year! You’ll find crappie, walleye, bass, and northern pike here. You can also fly fish below the dam, and a fish cleaning station is located within the park.

Forgot anything or just need additional supplies? The marina at Campers Point has firewood, ice, fishing and boating supplies, boat rentals, boat and RV storage, bait, groceries, snacks, drinks, gasoline, souvenirs, fishing and hunting licenses, and non-resident park passes.

While summertime may be the most popular time to visit the park, Tongue River Reservoir State Park also features amazing ice fishing and year-round campsites that support just that.

  • Take the boat out on the water! There are two boat ramps with docks, one at Campers Point and one at Pee Wee North.
  • Go for a swim! Sand Point has a small beach area for swimming.
  • Keep your eyes open for wildlife! You may see osprey, blue herons, deer, antelope, or bald eagles.
  • Bring your picnic! The designated day-use area has picnic tables at Campers Point and Sand Point.

Tongue River Reservoir has some of the best ice fishing in Montana.

Just ask Chris Jairell of Sheridan, WY who landed a massive 42-inch, 15-pound Tiger Muskie while ice fishing last year.

Tongue River Reservoir boasts miles and miles of ice to test your skill and get you out this winter.

You can also check The Marina's Facebook page to keep tabs on the water and weather conditions. They post regular updates as well as provide an opportunity to share your big fish stories. Just be prepared to provide photographic evidence when you do.

The Marina is also a great place to learn about what you can fish for, ice conditions, and travel tips. You can also call them at (406) 757-2225

Tongue River Reservoir State Park currently holds two state records for the weight of fish caught, including a 37.5 pound Northern Pike?

Lake Elmo State Park

Lake Elmo State Park

Lake Elmo State Park

Inside the city limits of Billings is Lake Elmo State Park. A large 64-acre reservoir, Lake Elmo is the perfect place to swim, paddle, fish, picnic, bird watch, or hike the 1.4-mile nature trail.  The Lake, originally known as Holling Lake Reservoir, was constructed to provide water to irrigated farmland as part of the Carey Land Act of 1894.  The water that fills the man-made lake is diverted from the Yellowstone River near Laurel, MT, and flows through 63 miles of gravity-fed canals before reaching the lake.

Things to do:

Prior to becoming a State Park in 1983, Lake Elmo was once the site of a two-story restaurant and night club known for dancing, big band music, and two-inch thick T-bone steaks.  Nearby property owners created beaches for swimming and even cleared snow from the lake in the winter to host ice skating.  At once point a thriving boat club was formed by local water skiing and motor boating enthusiasts.

The Regional Office for Montana Fish, Wildlife, and Parks is now located in the park.  The Regional Office houses an impressive collection of taxidermied birds, fish, and wildlife.  You can also purchase conservation licenses and apply for permits at the office which is open weekdays from 8 a.m. to 5 p.m.

A special feature of Lake Elmo is its Dog Park. The 200-square-foot fenced-in area includes a water area and is located on the west side of the lake. Each visitor is allowed a maximum of two dogs in this special area. Dogs must be 4 months or older. Dogs must be on a leash in all other areas of Lake Elmo State Park.

In the 1930s and 1940s, the Lake Elmo Supper Club drew people for dining, dancing, and watching water skiers just out the back door. The Supper Club burned down in 1946, but Lake Elmo continues to be a popular place today.

The reservoir was constructed in 1906 and serves as the storage basin for the Billings Bench Water Association. 

Your four-legged friends will love Lake Elmo State Park as much as you! The dog park at Lake Elmo is a 200-square-foot fenced area that includes access to the water located on the west side of the lake. You and two of your furry friends are allowed to run off-leash in this area, but must be on a leash in all other parts of the park. 

During the summer, the lake is stocked with fish regularly and Roger’s Pier is an excellent fishing spot on the south shore of the lake. And although a popular place to cool off in the summer, the lake can be accessed from many points which means these parks never feel too overcrowded. 

Only non-motorized boating is allowed on the lake though, so you won’t find any water skiing here like you could in the 30s and 40s!

Did You Know

Curious what other visitors have had to say about the park?

"It's basically on the outskirts of town. Fair sized, man made lake with stocked, variety of fish. No motorized craft allowed on the lake. There are picnic shelters, kids play ground, paved parking and restrooms. The water's edge is a work in progress with some beach areas and a boat ramp. No overnight camping. A great day trip."

"I really like this lake, not only is it large enough to explore it has great picknick areas, walking trails. It's very clean and well taken care of."

"Great family place. Canoeing, swimming, and just fun in the sun with people you care about."

"A beautiful lake right in town and watching the sunset there was breathtaking."
