Corps of Engineers policy prohibits private shoreline uses that give exclusive benefit to an individual or group. At Sam Rayburn that means floating, fixed and movable boat docks, and fixed or floating piers, along with significant vegetation modification such as formal landscaping. Portable roll-away docks are prohibited at all times, not merely restricted.
The restrictions on adjacent landowners are equally specific. Personal property may not be left on government land for more than 24 hours. Boats and floating devices may not be moored. Permanent structures and roads may not be built. A house on this lake does not come with its own place to tie up, and no permit converts it into one.
That single fact is why a waterfront page for Sam Rayburn that shows off boathouses would lose credibility with a local reader in about four seconds. Homes here do not have private boathouses the way they do on Lake Livingston or Toledo Bend, and pretending otherwise helps nobody.
Because so much rides on it, confirm the current position for your own frontage with the Sam Rayburn Project Office — 7696 RR 255 W, Jasper, TX 75951-9598, (409) 384-5716 — before you buy a property, a boat or a design around the idea of a dock. The Lower Neches Valley Authority holds the water supply contract, but the shoreline is the Corps' to police.
