Crayfish Study

The Pacific Northwest only has one native species of crayfish, but now there are a number of non-native species being found. Scientists do not know a lot about crayfish, native or non-native, in the Pacific Northwest and so you and your students can contribute critical data by learning about the crayfish at your site. Learn more about the Purpose of the Crayfish Study.

A large number of school groups participating in The River Mile expressed interest in helping with crayfish research so this study was created. This study is not limited to Lake Roosevelt. Any K-12 grade school group located in the Columbia River Watershed can participate and submit data about crayfish in their area. Any information collected and submitted will aid in the understanding of the distribution and populations of crayfish species in the Columbia River Watershed.
