But for the endangered Kootenai River white sturgeon, too much sediment can be a bad thing. <\/p>\n<p>It\u2019s not so much an issue for the adults, but the fish\u2019s eggs are easily smothered if there is too much sediment around. So keeping tabs on the sediments is therefore important for the long-term viability of the fish\u2019s populations, which need to be protected if goals for restoring the river are to be met.<\/p>\n<p>The Kootenai Tribe of Idaho is the primary organization working to improve conditions on the Kootenai River. In a recent work, they partnered with the U.S. Geological Survey to deploy acoustic Doppler velocity meters at three sites along the river near Bonners Ferry.<\/p>\n<p>The submerged devices emit sound pulses into the river at specific frequencies, similar to sonar. The sound pulses reflect off sediment suspended in the water and then scientists can use the strength of the return signal, called backscatter, to calculate the amount of sediment particles flowing through the river.<\/p>\n<p>The use of acoustic technology is improving the monitoring of sediments nationwide, researchers say. At monitoring sites along the Kootenai River, having the devices makes it possible to track high sediment transport through some of the most critical habitat reaches.<\/p>\n<p>Acoustic meters were deployed near Crossport, a site below Moyie Springs and a Kootenai tribal hatchery. These gathered measurements from 2011 through 2014 on suspended sediment concentrations.<\/p>\n<div id=\"attachment_24527\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-24527\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2016\/02\/kootenai_doppler.jpg\" alt=\"An acoustic Doppler velocity meter mounted on a track for instream deployment.

(Credit: U.S. Geological Survey)<\/p><\/div>\n<p>USGS scientists found that total suspended sediment concentrations were driven primarily by tributaries flowing into the Kootenai River between Libby Dam and the areas under study. And they were highest during rain-on-snow events.<\/p>\n<p>On average, the relative percentage of suspended sediment concentrations composed of fine materials was 73, 71, and 70 percent at the Moyie, Crossport, and tribal hatchery sites, respectively. Researchers found that suspended sand transport often increased with high streamflows, typically but not always associated with releases from Libby Dam. <\/p>\n<p>Scientists also found the measurements useful following a large December rain storm, after which they were able to track the sediment concentrations as they surged and then subsided. <\/p>\n<p>Members of the Kootenai Tribe say that the partnership with the USGS has provided a lot of valuable insights over the years. The knowledge has helped them to design and implement restoration projects, as well as evaluate their impacts.<\/p>\n<p>Full results of the study are published under open-access license in the USGS Publications Warehouse.<\/p>\n<p><em><span style=\"color: #808080;\">Top image:\u00a0Hydrologic technicians retrieve a bedload sample from the Kootenai River near Bonners Ferry, Idaho.
