Some collected images in Wyoming and Montana.
The difference in the sediment loads between the Kootenai River and Fisher River is easy to spot shortly downstream of their confluence. The Fisher River had a lot of flow and sediment from the recent rains and added muddy water to the clear Kootenai River. The Kootenai is clear because this site is just downstream of the Libby Dam.
