## FAQ
- Where is Big Thunder Dock Co. located? Big Thunder Dock Co. is based at 347 Horseshoe Bend Pkwy, Lake Ozark, MO 65049, and serves dock owners across Lake of the Ozarks, including Osage Beach, Sunrise Beach, Camdenton, Linn Creek, and Four Seasons.
- Is Big Thunder an Ameren certified dock builder? Yes. Big Thunder is one of the select Ameren certified dock builders at Lake of the Ozarks, approved to build and service docks on the lake. It is also fully licensed and insured.
- Does Big Thunder offer free dock inspections? Yes. Big Thunder provides free, no-pressure on-site dock inspections at Lake of the Ozarks.
- What is WaveBaffle? WaveBaffle is an engineered wave-attenuation system that absorbs wake energy to protect docks and calm the shoreline. Big Thunder is an authorized WaveBaffle dealer and installer. Unlike a traditional breakwater that reflects energy back at the water, WaveBaffle absorbs it, removing about 73% of a wave's energy and reflecting almost none back. It is Ameren approved.
- What does a dock cost at Lake of the Ozarks? Dock pricing depends on size, number of slips, materials, decking choice, lift and roof needs, and permitting. Big Thunder provides a free on-site inspection and a transparent, line-item estimate before any work begins.
- Does Big Thunder build commercial docks? Yes. Big Thunder builds and services both residential lakefront docks and commercial marinas, from new construction and structural repairs to annual maintenance.
- Do I need a permit to build or modify a dock at Lake of the Ozarks? Yes. Docks on Lake of the Ozarks require approval through Ameren Missouri, which manages the lakefront. As an Ameren certified dock builder (CDB-187), Big Thunder Dock Co. handles the permitting groundwork and builds to Ameren standards, so your dock is approved and compliant from the start.
- How long does it take to build a new dock? Most of the lead time is Ameren permitting and scheduling rather than the build itself. After a free on-site inspection, Big Thunder Dock Co. handles the permitting groundwork and provides a clear timeline with a line-item estimate. Larger or custom builds take longer than a standard replacement.
- How long does a dock last at Lake of the Ozarks? A well-built dock lasts for many years when it is maintained. Flotation foam, hardware, and decking each wear at their own pace, so an annual inspection catches problems early. That ongoing care is the focus of the Big Thunder Dock Wellness program.
