Aquatic Plant and Algae Identification
Descriptions, photographs, and line drawings of 100 aquatic plants.
Search Ecology's plants database to see which plants are growing in each
water body (not all water bodies in Washington have been surveyed).
Search Ecology's algae database to see if blue-green algae are
growing in each water body and if they are toxic (not all algae
blooms have been tested).
Information on how to press plants, prepare for mailing for
identification, how to distinguish look-alike aquatic plants.
Aquatic Plant Management
Descriptions of commonly used aquatic plant control
techniques including manual, biological, and chemical methods.
Specific methods used in Washington to eradicate or control Eurasian
watermilfoil.
Information about some of Washington's common
native aquatic plants.
Information about some of Washington's invasive
freshwater plants.
Aquatic Weed Grants
Grant Guidelines, lists of grant projects, grant applications,
sample grant applications and grant agreements.
Planning for Aquatic Plant Management
A manual that guides people through the steps needed
to develop a plan for the control of aquatic vegetation. Lake groups using herbicides under Washington's Nuisance
Weed and Algae Permit should use the guidance below.
Integrated Plan for Early Infestations of Eurasian
Watermilfoil
An integrated plan for the management of pioneering
infestations of the state-listed noxious weed Eurasian
watermilfoil (Myriophyllum spicatum).
Some Ecology-approved plans for Washington State listed
Noxious Aquatic Weeds are listed below. Many of these PDF files load slowly;
be patient.
Freshwater Noxious Emergent Integrated Pest Management Plan
(pdf file)
This plan covers noxious emergent freshwater plants such as
purple loosestrife, yellow iris, garden loosestrife, and
others and contains management information. This plan is
required to be used by those treating noxious, emergent weeds
under Washington's NPDES permit for state-listed noxious
weeds.
Pesticides to Control Aquatic Plants and Algae
Aquatic pesticide NPDES
permits for Washington (noxious weeds, aquatic plants and algae, irrigation,
mosquito, etc.).
Risk assessments and environmental impact statements for the aquatic use of 2,4-D, endothall, diquat,
and triclopyr.
Information about herbicide concentrations and other environmental
data collected from Washington's lakes after herbicide treatment for
noxious weed control.
This paper describes the pesticide evaluation process that will be
used to screen the approximately 750 pesticide active ingredients
that are currently registered in Washington State.
An
Innovative Approach to Applying Aquatic Herbicides
See how the Mason Lake group are using "tents" to contain aquatic
herbicides over small infestations of Eurasian watermilfoil.
Algae Control Program
Read about Ecology's new algae management program that
includes algae identification, toxicity testing, and coming
soon a new grant program.
Discover which algae pose threats to humans, pets, and
livestock.
Is your lake experiencing an algae bloom? See photographs
of blue-green blooms and find out how to have your algae
identified and tested for toxicity (Washington state waters
only).
Information about algae, control methods for algae,
nutrient-reduction technologies for lakes, and general lakes
information.
A small grant program for algae management in Washington
waters will start fall of 2007.
Search this database to see which Washington water bodies
experience toxic algae blooms.
Lake Information
The Washington
Lakes Book has lots of fun and useful information to help you
live with your lake.
Information about lake landscaping practices and forming a lake
association.
A great overview of water quality monitoring methods
for lakes and streams in language anybody can understand.
A list of lakes that Ecology has
monitored. Bathymetric maps are included for many Washington lakes.
Read about efforts to reduce phosphorus in common household
products.
