Sign Up Now! Our Sediment Study Sampling Starts December 20th, so please sign up for sampling dates and a training, if you haven’t done this yet. But if you’d like to sample, the dates fill up fast, so choose your date even if you haven’t completed the training. If you can’t make it, please cancel your sampling date. Learn more about the study, including reports and videos, below.

Our Sediment Study monitors turbidity in the Spokane River.

Hangman Creek pollutes the Spokane River with tons of sediment each day in the spring, choking sensitive native redband trout and burying their nests.

Hangman Creek pollutes the Spokane River with tons of sediment each day in the spring, choking sensitive native redband trout and burying their nests.

Each spring Hangman Creek fills with sediment, spewing tons of dirt into the Spokane River. This cloudy water is bad for fish, macroinvertebrates, and all who depend on them.

The Spokane Riverkeeper, with help from Spokane Fall Trout Unlimited, leads a citizen science monitoring project to study water transparency (turbidity) in Hangman Creek and the Spokane River.

You can volunteer for this study! Sign up for a training to help us to collect scientific data to protect the Spokane River! You will monitor water clarity (turbidity) in the Spokane River and Hangman Creek. We will use these data to determine the intensity and duration of degraded water quality in Hangman Creek and its effect on the Spokane River. Sign up below for a training (virtual on December 151th), in person on January 11th) and for sampling dates. If you missed the training, email jule@spokaneriverkeeper.org and he will train you personally!
