Oasis at Lakeport: What Opens in Osage Beach and When

Oasis at Lakeport, the amusement park and resort going up on Jeffries Road next to the Grand Glaize Bridge in Osage Beach, has a new opening date. The first phase is now expected by mid-April 2027, and eight of the park’s 12 rides are already standing, according to KY3’s October 7 report.

Below is what is being built, the order it opens in, and why the traffic it brings matters to anyone who owns land along Highway 54 and Osage Beach Parkway.

When Oasis at Lakeport Opens

The project opens in pieces. The amusement park comes first, the indoor water park follows about six months later, and the hotel comes last.

Dates as reported by KY3 on October 7, 2026. Each filled square is one ride standing.

Operating partner Todd Schneider told KY3 the park plans free admission and no extra parking fees for guests. Managing partner Fred Ross credited Brinkmann and its subcontractors with the construction work, and the Osage Beach Board of Aldermen was reviewing a bill that would make the park part of an entertainment district, which Schneider said would allow open containers throughout the park and at Dog Days Bar and Grill next door.

What’s Being Built on Jeffries Road

The site covers 25 acres, according to Brinkmann Constructors, the general contractor. The owners are a partnership of SkyView Partners, Tegethoff Development and Fred Ross, who owns Big Thunder Marine. LakeExpo names Jeff Tegethoff as the developer. Brinkmann’s project page splits the work into two phases.

Phase one

Nine-acre amusement park with roller coasters and family rides
200-foot observation wheel with lake views
800-space parking garage
Shops, restaurants and public boat slips

Phase two

13-story Marriott with 400 guest rooms and a conference center
50,000-square-foot indoor water park under a retractable glass roof
Spa, outdoor pool, fitness center and pickleball courts
Two levels of parking below grade

In KY3’s timeline the arcade opens with the park, and the water park opens ahead of the hotel, so the split on the ground may not match the two phases on paper exactly.

The Opening Date Has Moved Before

This isn’t the first schedule. When Osage Beach aldermen approved the development plan in June 2023, the project was expected to open in 2024, according to ABC17. In January 2026, LakeExpo’s roundup of projects to watch listed the park for fall 2026. KY3 noted construction delays in spring 2025, and the first phase now points to April 2027.

None of that is unusual for a project this size, but it’s a reason to treat April 2027 as a target and to check for updates before you plan around it.

What a Free Park Does to Year-Round Traffic

A park with free admission and no parking fee takes the cost out of a short visit, so a family can stop for an evening instead of planning a whole day around it. And the partners have pitched it as a year-round draw from the start. Back in 2023, Schneider said the project would offer “year-round attractions and entertainment for everyone at the lake to enjoy.” The plan the city’s planning commission reviewed that June called for the park to be open from 10 a.m. to 10 p.m., year-round, according to ABC17.

An indoor water park and a 400-room hotel are the pieces that keep running after the boats come out of the water. Mark Barrett, who owns Dog Days Bar and Grill, told KY3 he expects the park to bring customers both in season and off season.

The partners have planned for the cars. They completed traffic studies with MoDOT and plan to add a traffic signal on Jeffries Road, and Schneider said the team has mapped out how cars will flow in and out. Schneider called Oasis “one of the largest direct investments in tourism in the history of the state of Missouri.”

Why It Matters If You Own Frontage

Visitors to a park like this don’t only spend money inside the gate. They buy gas, eat out, store boats and book rooms, and the businesses that catch that spending want to be on the roads visitors already drive. Oasis sits at Highway 54 and Jeffries Road, so more of those trips run along the Highway 54 corridor through Osage Beach.

That corridor doesn’t have much open commercial land left. We wrote about that in our post on Lake of the Ozarks land for sale on Highway 54. All four properties in our portfolio of Lake of the Ozarks commercial real estate sit along Osage Beach Parkway and Highway 54, and three have renderings for visitor-facing uses like a destination restaurant, watercraft storage and a hotel.
