Scientific Evidence
There have been no Environmental Impact Statements on the impacts of sand and gravel dredging on the Kansas River since the 1990 Final Regulatory Report and Environmental Impact Statement on Commercial Dredging Activities on the Kansas River. Currently the United States Corps of Engineers is performing an Environmental Assessment on commercial dredging in the Kansas River. The results will likely be made public in the Fall of 2013.
Links to scientific publications and government reports on the impacts of sand dredging on the Kansas River and Missouri River are provided below.
