Flooding and silt topics of MSAC annual meeting

Join the discussion focused on Missouri River flooding and sedimentation Monday, March 19, in Wagner during the Missouri Sedimentation Action Coalition's annual membership meeting.

Tim Cowman will present "Anatomy of the Missouri River Flood 2011" at 7:30 p.m. at the Wagner Theater. The presentation will examine the hydrologic events that contributed to the historic flood of 2011.

Impacts of the flood on river geomorphology, the riparian ecosystem, and floodplain infrastructure will be discussed. The presentation will illustrate impacts to the free-flowing segments of the Missouri River between Pickstown, SD, and Ponca, NE, as well as impacts to the channelized river segment from Sioux City, IA, to Omaha, NE.

Cowman is the director of the Missouri River Institute at the University of South Dakota. He has a masters degree in Natural Sciences from USD. His work includes research on the geology and history of the Missouri River, with a focus on current and historical river geomorphology.

During its 11th annual membership meeting, MSAC will elect two individuals to its board of directors for three-year terms. The following two directors have expiring terms: Jason Glodt, representing Class I (Government) and Jeff Peters, representing Class II (Organizations.)

Membership will be updated on activities and future goals of the organization. Staff will issue a progress report on a new video presentation featuring photos between Pierre and Sioux City taken in November of 2011 illustrating sedimentation in and around the reservoirs.

MSAC will host an informal, public open house beginning at 6:30 p.m. at the Wagner Theater prior to the annual meeting. The public is invited to view MSAC displays and visit with area river management officials.

Tom Curran, Fort Randall Dam project manager for the U.S. Army Corps of Engineers, and Steven Mietz, National Park Service superintendent of the Missouri National Recreational River, are scheduled to attend. Les Labahn of the Randall RC&D also is scheduled to participate and can discuss the Lewis and Clark Watershed Implementation Project.

The public is invited to bring their questions and comments.

A regular, bi-monthly MSAC board of directors meeting is scheduled at 3:30 p.m. The public is invited to both meetings and the open house.

"Please put this date on your calendars. If we are to address sedimentation problems in the Missouri River main stem reservoirs we need to act as a unified coalition and encourage cooperation among the people who can engage in sediment management," said Sandy Korkow, MSAC's executive director.
