2024 Sediment Study Training Sign Up is closed, but if you’d like to volunteer contact Jule at [email protected]. Learn more at the below. Read our 2023 and 2024 report 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.
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 15th, in person on January 8th) and for sampling dates. If you missed the training, email [email protected] and he will train you personally!
