Brazilian Waterweed - Egeria Densa
DBW To Start Treatment of this
Invasive Weed
Updated Tuesday, November 9,
2010
The
Department of
Boating and Waterways
will begin spraying our waterways on April
1st, 2011 in an attempt to eradicate this
invasive weed from our beautiful waterways.
Our tidal flows can make treating these
weeds challenging but DBW is putting
together a detailed plan for treatment.
Funding may not be available in all years so
a comprehensive management system is being
put in place.
As we come into
the winter months, this species of aquatic
nuisance begins to die off when the water
temperature drops below 65 degrees. At it's
weakest in the spring, the DBW will treat
the plants with a safe chemical to further
eradicate it.
What can you do?
Pull and properly dispose of aquatic plants
and weeds! Here’s how:
-
Pull
the plants and weeds from their roots.
Remove the entire plant/weed, including
the roots.
-
Place
the entire plant/weed in garbage bags or
cans and move them far away from the
water. If plants/weeds are left to dry
on the dock or near the water line,
seeds will blow back into the water and
cause more growth.
-
Encourage your friends and neighbors to
properly remove and dispose of aquatic
plants/weeds near their property.
-
Avoid
any contamination of our waterways. All
spraying MUST be done by a licensed
pesticide applicator. This is required
under the
Clean Water and Endangered
Species Acts.
AQUATIC
WEEDS can be disposed of at the District’s
dump site from 9:30 – 10 a.m. and from
2:30-3 p.m., Monday – Friday. The dump site
is located just east of Discovery Bay on the
dirt levee road. For more location
information, please call Rec 800 at (925)
634-2351. No plastic bags, garbage,
or landscape trimmings are allowed. This is
a aquatic weed dump site only.
Thank you to
Supervisor
Piepho, The California Department of
Waterways, Reclamation District 800, and The
Discovery Bay Yacht Club for their efforts
on our behalf regarding this problem.
