Seasonal Drawdown
About the Lake

Built for Douglas's 40-foot swing.

Douglas has one of the steepest seasonal drawdowns of any lake in our service area — roughly 40 feet between summer pool and winter pool. That makes fixed pile-driven docks impractical for almost every shoreline; the floating dock category is essentially the only category for new builds on Douglas.

We build aluminum-frame floating systems with pile-guided anchoring rated for the full water-level range, plus integrated Floatair lifts sized to your boat. The result is a dock that rides the water level all year — no seasonal hauling, no winter storage, no waiting for summer pool to use the dock.

Fixed Docks

Built on pilings driven into the lakebed, our fixed docks provide a sturdy platform for life on the water, with options for covered boat slips, metal roofs, and custom layouts.

Douglas Lake FAQ

Common questions.

Why are fixed docks so rare on Douglas?

Douglas drops about 40 feet from summer pool to winter pool. A fixed dock built for summer pool sits 40 feet above the waterline in winter — unusable and structurally over-stressed. Floating systems with pile-guided travel are the standard for that reason.

Do you handle the TVA 26a permit on Douglas?

Yes — every Douglas build gets a 26a application filed and paid by us. The 40-foot drawdown spec is part of the submission.

How is Douglas different from Cherokee or Norris?

Drawdown. Cherokee swings about 25 feet, Norris around 30 (variable), Douglas around 40. That's the deciding factor on dock type.
