Plans by the Osage Nation to establish a casino and hotel at the Lake of the Ozarks are advancing, as a newly issued federal environmental study provides the clearest picture yet of what the development could entail. The 83-page Draft Environmental Assessment (EA), released by the Bureau of Indian Affairs (BIA) under the U.S. Department of the Interior, evaluates multiple scenarios for the 29-acre site in Lake Ozark.
Located at the intersection of Osage Beach Parkway and Bagnell Dam Boulevard, the land is currently owned by Osage Casinos. The federal assessment outlines three alternatives: no action on the site, development of a hotel without gaming, and the construction of a full resort-style casino and hotel—the Osage Nation’s preferred option.
Detailed Overview of the Proposed Development
The favored plan, designated “Option A” in the environmental report, calls for a substantial casino-resort complex. The project would include a 40,000-square-foot Class II gaming area featuring up to 750 electronic gaming machines, a 150-room hotel tower, and a variety of additional amenities such as a fitness center, swimming pool, event spaces, dining establishments, and 435 parking spaces. The total size of the building would span roughly 237,160 square feet.
According to the assessment, the proposed facility would generate an estimated $100.6 million in annual local economic activity and create around 455 permanent jobs. If regulatory approvals are granted, construction could begin in 2025, with an anticipated timeline of 12 to 18 months to complete the project, according to Lake Expo.
Federal Review Process and Next Steps
The development’s future hinges on two pivotal federal actions. First, the land must be placed into federal trust under the Indian Reorganization Act. Second, a “Two-Part Determination” is required under the Indian Gaming Regulatory Act (IGRA). This legal process must conclude that the casino serves the best interests of the Osage Nation and will not negatively affect the surrounding community. Missouri Governor Mike Kehoe would also need to sign off on this determination for the project to proceed.
In line with the National Environmental Policy Act (NEPA), the Draft EA evaluates the proposal’s potential effects on local water systems, traffic conditions, nearby wildlife, and community infrastructure. Importantly, the study found no significant environmental issues associated with the project. Public feedback on the assessment is being accepted until September 2, after which the BIA will decide whether to issue a Finding of No Significant Impact or require a more in-depth Environmental Impact Statement.
A Long Road to Development
The Osage Nation first announced its intentions to build a casino at the Lake in late 2021 after acquiring the former site of a Quality Inn, which has since been demolished. This initiative came as a competing proposal from the investor-led Osage River Gaming & Conventions group was also gaining attention. However, that effort faced a key legal hurdle—Missouri law only permits casinos near the Missouri and Mississippi Rivers. The group’s push to amend the state constitution failed during the November 2024 election, effectively halting their plans.
Unlike the investor-backed effort, the Osage Nation’s proposal bypasses state constitutional restrictions thanks to its tribal status and pursuit of federal approvals. The Nation has worked closely with local officials to ensure coordination on issues like infrastructure improvements and emergency response services, should the casino be greenlit.
Public Comment Period and Final Approval Process
A formal notice published in the Eldon Advertiser confirms that the Draft Environmental Assessment has been released for public review. This allows residents, stakeholders, and community leaders to weigh in on the project’s potential implications. Following the public comment period, a final decision will be made. Should the project receive the necessary clearances, a 30-day appeal window will open after the official announcement.
Should the Osage Nation’s plans move forward as expected, the development would mark a significant addition to the Lake of the Ozarks’ growing tourism and hospitality landscape, bringing with it major economic and employment benefits for the region. The outcome now depends on the final federal review, gubernatorial approval, and local community input.
