Finding the keys to sustain a reservoir like Lewis and Clark Lake not only involves engineering but also an economic framework to put solutions into action. Brigham Young University professor of civil and environmental engineering, Rollin Hotchkiss, will speak to both of those sedimentation issues at a public meeting beginning at 10:30 a.m., Monday, August 1, at The Landing, 104 Capital St., in downtown Yankton.

This meeting is hosted by the Missouri Sedimentation Action Coalition, a nonprofit organization dedicated to educating the public about the sedimentation problems in and around the Missouri River reservoirs. Hotchkiss has researched the cost benefit analysis approach and its shortcomings. At the Yankton meeting, he will relate that information to Gavins Point and Lewis and Clark Lake.

Hotchkiss has authored more than 150 papers and reports dealing with topics such as determining peak flows in watersheds and turbulence in natural channels and culverts. He also co-authored “Conversion of a Missouri River Dam and Reservoir to a Sustainable System: Sediment Management” with University of South Dakota researchers Howard E. Coker and Dennis A. Johnson in 2008.  The article was published in the Journal of the American Water Resources Association.

The August 1 presentation will include information about how dams impact water and sediment, upstream, within the reservoir and downstream. Other topics include: what can be done to mitigate sediment problems, why we have sediment problems, world-wide happenings, along with the cost benefit analysis approach.

Hotchkiss has been a professor at BYU since 2005 and is currently the Civil and Environmental Engineering Department Chairman. He earned his bachelor’s degree from BYU and his PhD in civil engineering from the University of Minnesota. Previously, he was a professor at the University of Nebraska-Lincoln and Washington State University.

MSAC encourages the public to attend this free event. The information is important to planners in all levels of government, engineers, non-governmental organizations, educators, other professionals and anyone concerned about the future of Lewis and Clark Lake and the other Missouri River reservoirs.
