Some community members had the chance to be scientists for the day at the Boise River.
Volunteers and trainers participated in the Ninth Annual Treasure Valley Watershed Watch Saturday.
Each volunteer was paired up with a professional scientist to do basic water-quality testing.
"Everybody loves the Boise River but not everybody probably knows the status of the river, so this gives folks a chance to understand the health of the river, take some basic water quality tests, gather some data, be scientists for a day, and connect with the environment," said Tim Merrick, public information officer for the U.S. Geological Survey.
There were a dozen sites along the Boise River from Lucky Peak to Caldwell.
Teams were able to identify native and non-native aquatic species in the river, while also testing water samples for dissolved oxygen, bacteria, phosphorus, and other water-quality parameters.
