Welcome

Oregon is home to over 100,000 miles of stream, river, and estuary habitat. The Aquatic Inventories Program (AQI) is a robust research and monitoring program with respected survey methodology and innovative techniques used to describe the numerous aquatic species and their habitats across this great state. Our data are collected by trained biologists and are used to determine factors limiting natural fish production, identify habitat protection and restoration needs, and provide information for fish management plans and policies. Whether you're seeking foundational knowledge, beginning monitoring initiatives, or guiding habitat restoration endeavors, our repository of information is your go-to resource for a deeper understanding of Oregon's aquatic ecosystems.

You can discover more information about AQI on this website.
