Prevent
the Spread of Zebra Mussels
Into
Our Lake!
Zebra Mussels cause IRREPARABLE
DAMAGE TO LAKES.Take every possible precaution to keep them out of our
lake.
Prior to putting any
vessel, tube, bait bucket, anything that has been in another body of water into
our lake, you must take the following steps.
“Clean. Drain. Dry.” Three simple, but important words.
That’s the message from the Nebraska Invasive Species Project.
CLEAN – Remove all plants,
animals, and mud, then thoroughly wash everything, including all crevices and
other hidden areas on your boat and equipment, or anything that was in another
body of water outside of North Lake.
DRAIN – Eliminate all
water before leaving the area, including wells, ballast, and engine colling
water.
DRY – Allow time for
your boat to completely dry before launching in other waters. At least 5 days prior to putting into North
Lake.
Zebra mussels spread
to new waterways when boats carrying mussels from infested waters are put into
uncontaminated rivers or lakes.
The most important
way for boaters to address the spread of zebra mussels is to check their
equipment for these aquatic hitchhikers and remove any visible mud, plants,
from the boat, fish, or animals. What may appear to be harmless species, such
as the zebra mussels, have been known to travel in ballast water, attached to
boats, and transported between reservoirs.Clean,
drain, and dry all equipment that comes into contact with the water. If
there is a place for water to collect, there is a chance that zebra mussels or
other similar invasive species may be transported, including on boat trailers.
Boaters should drain
the bilges and live wells in their boats, and if unable to be drained, a cup of
bleach can be added to kill any live mussels.
It is also a good
idea to dry the boat for several days before its next use. If possible,
power-wash the boat, motor, and trailer to scour off invisible juvenile
mussels.
If you have had your boat in another body of water, you
must have it sit out of any water for a week. Clean, drain, dry.
If you have been tubing, kayaking, canoeing, walking, or
fishing in the Platte River,
YOU MUST wash off all materials that were used in the
water. This includes your dog! Please rinse everything, dry everything, and
let it all sit out of water for at least 5 days before putting them back in the
North Lake!
If minnow buckets are used on another body of water, they
also need to be cleaned and dried out.
DO NOT put any minnows or fish caught in the Platte River,
or any other body of water in our lake.
What are zebra and quagga mussels?
Zebra and quagga mussels are freshwater
bivalve mollusks (animals with two shells). They are relatives of clams and
oysters. It is very difficult to tell the two species apart in the field. The
shell color of both mussels alternates between a yellowish and darker brown,
often forming stripes. Larvae are microscopic whereas adults can reach up to
two inches long. The zebra mussel is nearly triangular in shape and the quagga
mussel is more rounded. Unlike native North American freshwater mussels, which burrow in soft sediment, adult zebra and quagga
mussels can attach via small byssal threads to hard surfaces.
Both zebra and quagga mussels
can survive cold waters but cannot tolerate freezing. They can endure
temperatures between 1°–30°C (33°–86°F). Zebra mussels need waters above 10°C
(50°F) to reproduce while quagga mussels can reproduce in waters as cold as 9°C
(48°F). The embryos are microscopic. The larvae, called veligers, are
planktonic and free-floating. The veligers float in the water column or are
carried in the current for about four to eight weeks. The larvae develop shells
and settle onto any solid surface, including the skin or shells of native
aquatic species. Zebra mussels are native to the Black and Caspian Seas. Zebra
mussels were discovered in the Great Lakes in 1988. Quagga mussels are native
to the Dnieper River Drainage in the Ukraine and were first found in the Great
Lakes in 1989. Both species have since spread to more than 25 states.
They have recreational impacts.
These mussels encrust docks and
boats. Attached mussels increase drag on boats. Small mussels can get into
engine cooling systems causing overheating and damage. Increased hull and motor
fouling will result in increased maintenance costs on watercraft moored for
long periods of time. The weight of attached mussels can sink navigational
buoys.
Zebra and quagga mussels also
impact fish populations and reduce sport-fishing opportunities. Their sharp
shells can cut the feet of unsuspecting swimmers and beach goers.
ZEBRA MUSSELS ARE BAD AND WE DO NOT WANT THEM IN OUR LAKE!
THEY WILL DESTROY OUR
LAKE AND PROPERTY.
