Tenkiller earned the nickname Oklahoma’s clear water wonderland honestly, and that clarity is the reason it became the state’s premier scuba destination. It also creates a hazard boaters elsewhere never think about: on a summer weekend there are people in the water beneath you, marked by dive flags that not every operator recognizes or respects. Striking a diver is a catastrophic liability event, and it is the exposure we raise first with anyone keeping a boat here. The lake itself is steep and rocky, with bluff walls dropping fast and structure that punishes a misjudged line even in water you can see through. Above the dam, the Illinois is a designated scenic river packed with canoes, kayaks, and rafts all summer, which is a different kind of traffic entirely. A watercraft policy covers the hull and motor, schedules the trailer, and carries the liability limits this particular mix of water actually calls for.
