Water-quality data are collected in Lake Koocanusa at the international boundary and on the Kootenai River downstream of Libby Dam. Water depth changes over the season and the platform records data from the water surface to the bottom of the lake, regardless of the lake's depth. Data in graphs are updated weekly to present the latest results. All data are considered provisional.
