(SPRINGFIELD, SD) – Join the Missouri Sedimentation Action Coalition for its 23rd Annual Membership Meeting scheduled for 10 a.m., Thursday, May 2, 2024 at the Ponca Tribe of Nebraska – Tribal Headquarters Conference Room in Niobrara, Nebraska at 2523 Woodbine Street.

The meeting is free and open to the public. Interested people are encouraged to attend. A virtual meeting link is available for those who cannot attend in person. Register by clicking the box above.

Paul Boyd, hydraulic engineer – River and Reservoir Engineering Section of the U.S. Army Corps of Engineers (USACE) – Omaha District, will provide an update brief on the sediment collector pilot project planned for at least a week-long installation on the Niobrara River later this summer. The project, funded by the Corps’ Regional Sediment Management (RSM) Program, is coordinated by USACE Omaha District and in collaboration with the Corps’ Engineering Development and Research Center (ERDC) and the Missouri Sedimentation Action Coalition (MSAC).

For decades, the Niobrara River with its nearly unlimited sand supply has been the single, largest contributor of the sedimentation building up in the Lewis and Clark Lake delta. MSAC sees this short-term collector pilot project with the potential of sparking long-term results. Over the past several years the group has focused on the Lewis and Clark Lake region as the waterbody behind Gavins Point Dam will be the first of the six Missouri River mainstem reservoirs to fill with sediment if no action is taken. Phase 2 of a Section 22 Planning Assistance to States study requested by MSAC to develop a sediment management plan for this region was released at the end of 2023. Next steps will also be discussed at the annual meeting.

Additional business for MSAC’s annual meeting includes a Board of Directors member election. MSAC’s Board of Director members with terms expiring are: Tim Cowman, of Vermillion, Class I – Governmental Entities, and Kersten Johnson, of Sioux Falls, Class II-Organizations.

MSAC, a 501c3 nonprofit organization, was organized in 2001. It is dedicated to educating the public and to promoting the intelligent use of all available programs and funds to alleviate the sedimentation-caused problems of the Missouri River main-stem reservoirs. MSAC supports a sustainable approach to reservoir management, envisioning doing what is necessary to extend the storage capacity of the reservoir as far into the future as possible recognizing the value of our most precious resource – water.

Paul Boyd, hydraulic engineer – River and Reservoir Engineering Section of the USACE – Omaha District, will provide an update brief on Phase 2 and next steps. Joining Boyd will be Justin Brewer, Chief, Economics and Planning Quality Review for USACE – Omaha District. Phase 2 is part of the effort by MSAC, stakeholders and the USACE to develop a sediment management plan for the Lewis and Clark Lake region. Phase 2 includes a detailed economic inventory of benefits and a review of possible sediment management actions that could produce positive sustainability benefits. Next steps will be discussed.

Shortly after Gavins Point Dam was completed in 1957 near Yankton, SD, people at the upper end of the lake and upstream began to feel the impacts of accumulating sediment. Currently, the lake is at least 30 percent full of sediment and by the year 2045 it is projected to be 50% full of sediment. In 2018, MSAC requested technical assistance from the USACE to develop a sediment management plan for the Lewis and Clark Lake region. The project is jointly funded by the USACE and the local sponsor, MSAC. To date, 14 stakeholders along with MSAC and its members have contributed funds to the local effort. MSAC anticipates lessons learned in this process will help the other Missouri River reservoirs in future planning.

Additional business for MSAC’s annual meeting include a Board of Directors member election. MSAC’s Board of Director members with terms expiring are: Mark Simpson, at large, and Paul Lepisto, at large, and Mary Hurd, at large.

Mazdak to outline technology focused on addressing reservoir sedimentation
Join MSAC for a free webinar

Emerging technologies could assist in lengthening the lifespans of the nation’s reservoirs plagued by sedimentation. The Missouri Sedimentation Action Coalition invites the public to learn more about one approach from Mazdak International Inc., during a free webinar Friday, Oct. 28^th beginning at 11 a.m. central.

Mazdak International Inc. of Sumas, Washington, was a finalist in the Guardians of the Reservoir Prize Competition and captured the Innovation Award in September with its slurry pulsejet engine. Baha Abulnaga and David Dibley of Mazdak developed this new technology.

Abulnaga will outline the technology and provide information about another of its projects designed to address the transport of sediments.

“The Guardians of Reservoirs noticed that current technology at depth exceeding 50 feet was very limited and challenged the innovators for new solutions for depth of 50 feet to 200 feet or even deeper, such as the Hoover Dam that is 600 feet deep,” Abulnaga said. “Mazdak International developed a new submersible platform that operates on the principle of an internal combustion liquid piston engine. The submersible dives to the depth of 200 feet and operated on the principle of creating the pressure needed to push the slurry up to a mother barge. This is achieved by the detonation of a mixture of a gaseous fuel and air against a liquid piston of dredged sediments and water. Fuel and compressed air are supplied from the mother barge, while slurry and exhaust gases are directed in the opposite direction in separate pipes to the mother barge and then pumped further around the dam in a floating slurry pipeline. The invention is called ‘Slurry Pulsejet Engine’ because it generates pulses of slurry.”

The inventors are also working on collecting methane emissions from reservoirs to convert them as fuel for dredging using the slurry pulsejet engine. It is estimated that the methane emissions from water lakes, rivers and reservoirs could cover all the electricity needs of the Earth for 2018, Abulnaga said.

Continued sedimentation at the nation’s reservoirs threatens project benefits and impacts the environment downstream of dams. It can also impact areas upstream of the reservoir including tributaries.

MSAC intends to offer additional webinars introducing emerging reservoir sedimentation management technologies. MSAC continues to develop a sediment management plan with stakeholders and river managers for the Lewis and Clark Lake region. MSAC is a 501c3 nonprofit organization dedicated to education and promoting action to address sedimentation in and around the Missouri River reservoirs.

The Bureau of Reclamation selected D-Sediment team from Germany as the prize winner of the Guardians of the Reservoir Prize Competition, according to Reclamation’s press release dated Sept. 15, 2022. The 3 D Dredger™ Team was presented with the Versatility Award. Reclamation partnered with the U.S. Army Corps of Engineers and NASA Tournament Lab and HeroX on this competition, which was launched on July 14, 2020 to develop more cost-effective sediment removal methods for reservoirs.

Two hydraulic engineers will provide a special presentation entitled “How Bureau of Reclamation is Reframing Reservoir Sedimentation.” Tim Randle and Jennifer Bountry, based in the Bureau’s Denver Sedimentation and River Hydraulics Group office, will join MSAC’s annual meeting via webinar.

MSAC has requested an update on the Guardians of the Reservoir Challenge. The Bureau of Reclamation, in collaboration with the U.S. Army Corps of Engineers, is sponsoring a three-phase competition spanning nearly two years that seeks development of more cost-effective sediment removal methods for reservoirs. This competition builds upon the successes of the “Sediment Removal Techniques for Reservoir Sustainability” competition, and looks to continue progress in the development of new processes and technologies that collect and/or transport sediment from reservoirs at a rate that sustains their current capacity.

In June of 2021, MSAC collaborated with the U.S. Army Corps of Engineers to host a Solutions Workshop as part of Phase 2 to develop a sediment management plan for the Lewis and Clark Lake region. Shortly after Gavins Point Dam was completed in 1957 near Yankton, SD, people at the upper end of the lake and upstream began to feel the impacts of accumulating sediment. Currently, the lake is at least 30 percent full of sediment and by the year 2045 it is projected to be 50% full of sediment. The project to develop a sediment management plan is jointly funded by the U.S. Army Corps of Engineers and the local sponsor, MSAC. To date, 14 stakeholders along with MSAC and its members have contributed funds to the local effort.
