We also keep a statewide clearinghouse for lake data from across the state. This includes historical monitoring and current sampling by Ecology scientists and data compiled under Ecology-funded projects by local governments. Data, including some photographs and lake-bottom maps (bathymetry), are found in the lakes module of the Coastal Atlas database. Look up a lake below.
We coordinated a large lake-monitoring program from 1989 – 1999 to identify statewide water quality concerns. We tested for dissolved oxygen, water clarity, temperature, and contaminants. While this program is no longer funded, we maintain this data. We also monitor some lakes each year for toxic metals and other chemicals.
We participate in EPA's National Lakes Assessment
every five years. Data are collected on a random sampling of lakes representing different regions of the state. We partnered with the Environmental Protection Agency (EPA) on this project in 2007, 2012, and 2017. We will report on the 2017 research when analysis is complete.
