Historic - Quagga Mussel Handout -before infestation

E-mail Print PDF

Starting on June 20, 2013 a Handout is being given to all arriving boaters at NPS entrance booths, stapled to the back of the Green Mussel Certificate. The informational document states that Decontamination is required when leaving Lake Powell.

Here are the facts:

Mussels were discovered at Lake Powell in March 2013.  It is now possible that mussels can attach to your boat while at the lake. Therefore, live mussels must be removed before leaving the lake.  This requires you to inspect your boat before leaving Lake Powell as it is not legal to transport mussels along the highway in UT or AZ

While at the ramp you must clean all mud and debris from your boat and drain water from ballast tanks, bilge, livewells and engine.  Remove the plug. Tilt motor up and down until no water drains out. Remove any foreign matter from boat and trailer.

This is the first step in a complete decontamination process.  The second step must occur before the boat is launched in a new water.

The boat can be dried for 7 days (during summer) at your home. Or if you wish to launch before the drying period is complete then the boat must be professionally decontaminated with scalding water (140 degrees) before launching  at a new water. Phone numbers are given below to find a decontamination station.

Utah Division of Wildlife Resources will set up boater check points along the highways to ensure that departing boaters have taken these precautions and that boats driving along the Utah highways are clean, drained and dry.

Please do your part to prevent mussels from being moved to new waters in Utah and other states.

The text of the informational document which you will receive at Lake Powell is as follows:

DECONTAMINATION REQUIRED AT LAKE POWELL

In March 2013, quagga mussels were discovered in Lake Powell. These tiny clams can reproduce quickly and attach to almost any
underwater surface. If they accumulate, they can damage irrigation pipes, boat engines, intake valves and other submerged items.
The mussels’ microscopic larvae can hide in water that accumulates on your boat and recreational equipment. To prevent these
invasive mussels from spreading to other lakes and reservoirs, anyone who uses a watercraft at Lake Powell must:
decontaminate it after leaving the water.
Why is decontamination mandatory?
It is critically important to protect our waterbodies from invasive species. If our recreation areas become infested, access to your
favorite lake or reservoir could be restricted. We don’t want to see this happen, so we’ve provided some easy decontamination
processes for everyone who boats at Lake Powell. By following these laws, you — the boaters — can help keep waters clean and open
for everyone.
Decontamination is simple
Under Utah law, you are required to decontaminate your boat when leaving Lake Powell. This means that immediately
after boating — while you are still onsite at the lake — you must clean any mud and plants off your boat and drain all its water (from
the wells, ballast and lower-engine unit). Then, there are two easy options to finalize the decontamination process:
Option #1
— Before boating in another water, you must dry your boat and equipment completely: 7 days in summer (5 days in
Arizona), 18 days in spring/fall and 30 days in winter.
Option #2
— If do not have time to dry your boat completely (as specied above), please contact the Utah Division of Wildlife
Resources for a free, professional decontamination before you boat in another water. Contact numbers are found here:

Stop for checkpoints
Law enforcement personnel will conduct random checkpoints near Lake Powell during the 2013 boating season. If you are
transporting a watercraft, you will be required to stop during the checkpoints. The primary goals of the checkpoints are to:
• Verify that water or mussels are not being transported
• Educate boaters about the importance of properly decontaminating their watercraft and equipment
