Anchoring A Houseboat

How Should I Anchor My Boat?

WE THANK the many boaters who anchor only in ways that preserve the resources we all love, while ensuring the safety of future users!

Properly anchor your houseboat


  • At a slow idle speed, approach a sandy beach in a location protected from wind or away from large areas of open water, like a cove.
  • Position the boat just far enough offshore so its bouncing does not create a divot on shore. Or place an old tire under the bow to protect the rock (and your boat) from being damaged.
  • Place anchors on the beach at a 45 degree angle from the cleats on the stern of the houseboat. for more stability, place similar lines from the cleats midway down the sides of the houseboat.
  • Dig 2-foot holes and bury the anchors with the points down and toward the boat.
  • Be sure to check the anchor lines every morning/night for tightness. You may have to adjust lines as the lake rises or falls.
  • When you leave, fill in the holes on the beach with sand and leave the area looking like you were never there. This is how temporarily burying anchors in sand will leave the area unimpaired for future generations, a requirement for all NPS lands. Respect other visitors and protect the quality of their experience.

Vessels may also utilize other alternative anchoring methods such as anchor bags.

Pin Anchoring / Houseboat Staking

Pin anchoring/houseboat staking is the act of anchoring vessels by placing a stake into a natural rock feature. This includes reusing existing pin anchors and/or holes. Anchoring vessels by pin anchoring is illegal because it impairs the resources. All units of the National Park Service are guided by the Organic Act. This Congressional mandate defines the dual mission of the National Park Service, both to conserve park resources and provide for their use and enjoyment in such a manner and by such means as will leave them unimpaired for future generations.

Federal Code of Regulations. Title 36, Chapter 2.1 (a)(1)(iv) covers the Preservation of Natural Resources.
(a) Except as otherwise provided in this chapter, the following is prohibited:
(1) Possessing, destroying, injuring, defacing, removing, digging, or disturbing from its natural state:
(iv) A mineral resource.
Houseboat Staking is also considered vandalism. (Reference 36 CFR 2.31 (a) (3) Vandalism. Destroying, injuring, defacing, or damaging property or real property.)
In accordance with regulations and the delegated authority provided in Title 36, Code of Federal Regulations, Chapter 1, Part 1, authorized by Title 16, United
States Code, Subsection 3, the provisions of Section 1.5(a)(1) are established for:

  • Pin anchoring: The act of anchoring vessels utilizing a device inserted into the rock either in a natural opening or one created by a person. This includes reusing existing pin anchors and/or holes.

Determination: The practice of pin anchoring within the boundaries of Glen Canyon NRA is considered injuring, defacing, and disturbing to mineral, archeological, and paleontological resources. Pinning into sandstone creates a permanent hole. As lake levels rise and fall, water rapidly dissipates carbonate minerals from the pinning hole, weakening the surrounding stone. This increases the development of geological hazards and rock falls as the sandstone fractures and flakes at an increased rate. Glen Canyon NRA has over 2,500 documented archeological and paleontological sites throughout the park. Pin anchoring can cause irreversible damage to these resources. Pins sometimes become permanently lodged in the sandstone, posing a significant safety hazard to visitors and vessels.

If I can't find a sandy beach it's not safe to anchor my boat without drilling a few holes.

If you cannot find a sandy beach on which to properly anchor your boat, you can tie your line around a boulder, or hold it down with a temporary weight such as approved anchor bags. If you are doing it right, it should take four-six anchor lines at the most, depending on the size of your boat. More information about anchor bags / alternative anchoring.

We also do not recommend using climbing gear as temporary anchors. Lake Powell sandstone is not solid enough to firmly place this gear. The movement of the water and lines could dislodge climbing cams, and the spreading nature of the cam may further destabilize the rock.

But the holes were here when I got here. I'm just reusing them.

"Reusing" holes only make them deeper and wider - every time someone "cleans the hole out" with drills more of the sandstone is scraped away. This weakens the sandstone and accelerates crumbling and damage. In addition, you might think you need a few extra holes, just to make sure your boat is good and tight. That's how these rock beaches end up with dozens of holes.

Swimming at the rocky slope is so much more fun without having to worry about getting impaled.

Why else should I care?

Lake Powell is constantly changing. The beach you see today may have been fully underwater a few months ago, and the deep water you just swam in today may be completely exposed rock in a few months. When a boat pulls up to a rocky beach, the captain cannot see directly underneath the bow. If there are stakes left in the rock, they could possibly rip through the hull of the unsuspecting boat. Swimmers are also at danger on the sides of rocky beaches.

What can I do to help prevent the destruction of Lake Powell's shoreline?

Education first, then enforcement.

Everyone who loves Lake Powell is encouraged to help by using the Powell Watch Program, “if you see something, say something.” Help us out on Lake Powell! If you see any boaters pounding stakes into the rock, or drilling holes in order to set stakes, send us a message at e-mail us. The message will go to our Dispatch Center and will be processed accordingly.

In an emergency, call 911 or hail National Park Service on Marine Band 16.

If boaters don’t respond to education, enforcement is the next step. Drilling holes in rock for pin anchoring is illegal and vessels found in violation will be cited.

Thank You to the boaters who enjoy the resources we all love, while protecting them for future generations!
