About Us

Research & Data

Ecology provides the high-quality science that is the foundation of Washington state environmental policy. Our monitoring, assessment, and modeling services provide a data-rich understanding of our state’s land, air, and water. We provide access to that data through reports, databases, maps and user-friendly online tools.

Wastewater testing
Whole effluent toxicity testing ensures wastewater does not harm aquatic life.
tTools for ArcGIS
An ArcMap Python add-in with tools that analyze stream-channel attributes and near-stream topography and vegetation to estimate effective shade inputs for use in temperature modeling programs.
Habitat monitoring
We collect data on the health of environmental systems that support plant and animal life.
tTools for ArcGIS 9.x (Build 7.5.3)
An older version (for 9.x) of an ArcMap Python add-in with tools that analyze stream-channel attributes and near-stream topography and vegetation to estimate effective shade inputs for use in temperature modeling programs.
Puget Sound Tide Model
A research tool programmed in Python by David Finlayson for predicting the tides of the Sound. The model was originally developed by Lavelle et al. (1988) at NOAA PMEL and subsequently updated by H. Mofjeld to include the full suite of standard tidal constituents.
Freshwater fish contaminant monitoring
We analyze freshwater fish for various toxic chemicals.
Modeling the environment
Computer models mathematically represent part of the environment to predict potential changes.
Models and tools for water quality improvement
We use models to help predict water quality changes to help us find strategies to address pollution.
Marine water & sediment monitoring
We conduct water and sediment long-term monitoring to identify ecosystem change.
Models & spreadsheets
Computer models predict changes and spreadsheets calculate. We offer these tools to the public.
Eyes over Puget Sound
We use aerial photos and data from our monitoring stations and ferries to report on Puget Sound.
Monitoring watersheds for salmonids
Does salmon habitat restoration work? Our Intensively Monitored Watersheds program aims to find out.
River & stream water quality index
How is your river doing? The Water Quality Index can help you learn about river & stream health.
Stream biological monitoring
We evaluate the health of rivers and streams by studying multiple aquatic communities.
Forest practices effectiveness monitoring
We evaluate whether forest practices rules protect fish, wildlife, and water quality.
Watershed health monitoring cycles
Learn about past watershed monitoring cycles that give us a snapshot of regional trends.
SolRad
A solar position and solar radiation calculator for Excel/VBA.
Manning's n calculator
An Excel/VBA program to calculate Manning's n (or depth) from cross-section data for trapezoidal or rectangular channels based on equation 14.32 in Chapra's Surface water quality modeling textbook.
Environmental Information Management System (EIM) - search data
Access to discrete and time-series environmental data for air, water, soil, sediment, aquatic animals, and plants.
QA Project Plan template
The template includes information and instructions needed for the preparation of a QA Project Plan. Some of the text will be deleted as the plan is prepared.
