An Education Program of the National Park Service



The River Mile currently has 4 projects in which groups can participate in collecting and sharing data with everyone in the network (and the world). They are a crayfish study, a plant inventory, an animal inventory and a water quality monitoring program. Data submission and field collection methods are being continuely enhanced. We use several methods for sharing data with the network. All methods feature the ability for everyone to obtain any of the data. Our two main methods are ArcGIS Online and iNaturalist. Which you choose depends on what technology is available for your and your students’ use.

Crayfish Study »

Columbia River Watershed 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.Additional information about this study and its protocols is available on The River Mile’s webpages and by request.

Water Quality Monitoring »

Water, and clean water especially, is essential to life on Earth. Water Quality monitoring on a regular basis is important for the understanding of watershed health. You will need to collect enough data over time so you can tell what is likely to be normal results so you can tell when there are changes.

Plant & Animal Inventories »

It is important to know as much about your site as possible in order to understand the factors affecting watershed health in your location. Besides collecting water quality samples you need to understand how the plants, animals and humans use and rely on your site
