Court orders Edenville Dam owner do emergency inspection By Stephanie Parkinson, June 15th 2020, nBC25news.Com A judge in the United States DistriCt Court DistriCt of MiChigan Southern Division has ordered BoyCe Hydro, the owner of the Edenville Dam, to Complete an emergenCy inspeCtion of the Edenville Dam. A judge in the United States DistriCt Court DistriCt of MiChigan Southern Division 1 Copy obtained from the National Performance of Dams Program: http://npdp.stanford.edu has ordered Boyce Hydro, the owner of the Edenville Dam, to complete an emergency inspeCtion of the Edenville Dam. MiChigan Attorney General Dana Nessel took this matter to Court because it has been nearly three weeks sinCe the state ordered BoyCe Hydro to do this inspeCtion. Nessel Believes the Edenville Dam still poses a significant safety threat. The Edenville Dam failed on May 19. 10,000 people were evacuated and Midland County saw CatastrophiC flooding. The judge has ordered Boyce Hydro to submit reports for part of this inspeCtion by June 19, and the rest of the work be completed by June 24. An attorney for Sanford Dam BoyCe Hydro told Mid MiChigan NOW the inspeCtion was done By an engineer on June 10, But the reports had not Been Completed and sent to the state. (What shape are the other dams in MI?) Kalamazoo County’s largest dam does not pose a safety threat, officials say By Brian MCViCar | mlive.Com, Jun 15, 2020 KALAMAZOO, MI — Six miles east of downtown Kalamazoo sits Morrow Dam, the largest dam in the county. Standing 26-feet tall, the hydroeleCtriC power dam’s concrete walls and mechanical equipment serve a dual purpose: generating millions of hours of clean energy and, during periods of intense rain, keeping countless gallons of water from rushing into the Kalamazoo River. In the wake of historiC flooding caused by the Edenville Dam failure in mid-MiChigan, some residents are no douBt asking: Could the Morrow Dam suffer the same fate during a catastrophiC storm? (Dam removal. Always at least one story. It’s guaranteed that not everyBody is waiting for dam removal.) 60-Foot Dam to Be Removed From Cuyahoga River By RaChele Mongiovi, Ohio, Jun. 15, 2020, speCtrumnews1.Com CUYAHOGA FALLS, Ohio — At 60 feet high and 400 feet wide, the Gorge Dam is a site to see. It's situated on the Cuyahoga River in Gorge Metro Park in Cuyahoga Falls. • The Gorge Dam degrades the water quality and provides a horrible habitat for river species • Removal of the dam will speed up the flow of the water, providing reCreation for experienCed kayakers • DeConstruCtion of the dam Could start in 2023 ConstruCted in 1913, the dam powered a hydroeleCtriC power plant and provided Cooling water for a coal power plant. "When you put a dam on a river you essentially turn a fast, free-flowing river into a segmented, slow water, almost like a lake environment, it's no longer a river," said Dr. John Peck, professor of geosciences, University of Akron. 2 Copy obtained from the National Performance of Dams Program: http://npdp.stanford.edu PeCk says the Gorge Dam degrades the water quality and provides a horriBle habitat for river species. It is now known as the single greatest unresolved water quality problem on the river. "What we found upstream is that onCe these dams were removed they were a tremendous benefit to the communities, that not only did we improve water quality within a year after the dams had come down, they created wonderful plaCes for people to be and wonderful aCCess to the river where there Been none," said Elaine Marsh, watershed specialist, Summit Metro Parks. A regional effort from Summit Metro Parks, the EPA, First Energy and other agenCies have Been pushing for the dam's removal. Removing the dam will speed up the flow of the water, providing reCreation for experienCed kayakers. "OnCe the 60-foot dam comes out, we're going to have access to the entire river, so right now there's a mile and a half of dam lake and when that is removed, somewhere in there is going to be ledges and rapids," said Donald Howdyshell, an experienced kayaker. Howdyshell has Been white water kayaking for five years. The dam currently sits right in the middle of two and a half miles of white water. "I think everyBody, from kayakers to hikers, are waiting for that dam to Come down, everyBody wants to know what's hidden underneath that water BeCause noBody has seen it, noBody alive today knows what it looks like," said Howdyshell. Before the deConstruCtion of the dam, sediment will need to Be removed first. "Behind the Gorge, there's a phenomenal amount of sediment, 900,000 cuBiC yards and if they didn't, all that material would erode downstream, and it's slightly polluted, it would fertilize the lower Cuyahoga River and we don't want that to happen," said PeCk. OnCe the sediment is removed, the ConCrete dam will be hammered away and hauled off-site, bringing the Cuyahoga River back to its natural state. "To have white water is really an unusual thing and on a major river like the Cuyahoga, it's really a big deal, so we will be an attraction to paddlers states away," said Marsh. The earliest the deconstruction of the dam could start is 2023. (Another Cuyahugo River dam removal,) Brecksville dam demolition expected to be completed before July June 19, 2020, .scriptype.com ContraCtors Began the proCess of removing the BreCksville Dam from the Cuyahoga River on May 21. Removing the dam will allow the river to flow freely through the Cuyahoga Valley National Park for the first time in over 190 years, improving natural conditions and recreational access. Kokosing Industrial is the Contractor performing the work. The National Park ServiCe has CollaBorated for over a deCade with the Ohio Environmental ProteCtion AgenCy, United States Army Corps of Engineers, Ohio Department of Natural Resources and Friends of the Crooked River to prepare for the project. The seCtion of the Ohio & Erie Canal Towpath Trail near the river will Be Closed for the duration of the projeCt (through SeptemBer). However, a parallel seCtion of trail will remain availaBle, so trail use should not be interrupted. \ Trail users should Be prepared to stop if ContraCtors need to cross the open section of trail with heavy equipment. The river aBove and Below the dam within the construCtion area is closed to paddlers and anglers. Paddlers wishing to portage around the dam must use the Towpath Trail on the east side of the river. The railroad tracks are closed to all pedestrians north of the railroad boarding station. Due to the inaBility to provide enough spaCe for soCial distanCing, the NPS will not estaBlish a puBliC viewing area for this projeCt. It will provide updates on social media and at nps.gov/cuva/learn/dam-removal.htm . The Current ConCrete dam, Built in 1951 to provide water to the AmeriCan Steel and Wire Company, stands eight feet tall and 163 feet aCross. It is referred to as the BreCksville Dam and/or the Canal Diversion Dam. The ConstruCtion of the modern dam submerged the remnants of the wooden Pinery Dam, Built in 1827 to divert water from the Cuyahoga River into the newly constructed Ohio & Erie Canal. Although no longer needed to Cool the steel mills downstream, the BreCksville Dam still feeds the watered seCtion of the Ohio & Erie Canal, part of whiCh is 3 Copy obtained from the National Performance of Dams Program: http://npdp.stanford.edu designated a National Historic Landmark. Dams, however, impair fish haBitat, alter streamflow and water temperatures and create increased sedimentation of rivers and streams, significantly decreasing water quality. ContraCtors Created an opening in the dam to allow water and sediment to flow and lower the water behind the dam. With lower water levels, cultural resources will Be doCumented Before the Complete removal of the BreCksville and Pinery dams. The demolition phase of the project is expected to be complete By late June, depending on weather conditions.

Mueller, Member Manager Mr. Lee W. Mueller, Member Manager Boyce Hydro Power, LLC Boyce Hydro Power, LLC 6000 South M-30 10120 W. Flamingo Rd., Suite 4, #192 P.O. Box 15 Las Vegas, Nevada 89147 Edenville, Michigan 48620 SUBJECT: Emergency Order Edenville Dam, Dam ID No. 549 Gladwin County, T19N, R02W, Section 27 Dear Mr. Mueller: The Edenville Dam, Dam ID No. 549, is regulated under Part 315, Dam Safety, (Part 315) of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA). On May 19, 2020, the Edenville Dam suffered a catastrophic breach of its earthen embankment which caused an uncontrolled release of impounded water from Wixom Lake. As a result, the Tittabawassee River side of the impoundment was mostly drained, and the flow of the Tobacco River was diverted through the causeway, partially lowering the Tobacco side of the impoundment. However, both the Tittabawassee portion of the dam and the Tobacco River side of the impoundment are still maintaining head, continue to meet the Part 315 definition of a “dam” and still pose a significant threat to public health and safety and the natural resources of the state. Currently the Tittabawassee side holds back roughly 10 feet of head, while the Tobacco side is holding back nearly 30 feet of head. During the breach, the Tobacco River side earthen embankment sustained significant damage, which could endanger the remainder of the dam, potentially causing another uncontrolled release of impounded water.

  • Preliminary Report on the Edenville Dam Failure and Response Efforts
    STATE OF MICHIGAN DEPARTMENT OF ENVIRONMENT, GREAT LAKES, AND ENERGY EGLE LANSING GRETCHEN WHITMER LIESL EICHLER CLARK GOVERNOR DIRECTOR August 31, 2020 VIA E-MAIL The Honorable Gretchen Whitmer Office of the Governor P.O. Box 30013 Lansing, Michigan 48909 Dear Governor Whitmer: Per your directive, please find the attached report detailing initial steps the Michigan Department of Environment, Great Lakes, and Energy (EGLE) is taking to find the answers we all seek regarding the Edenville and Sanford dam collapses of May 19, 2020. The historic rain event that led to the dam failure and catastrophic 500-year flooding event in mid-Michigan illuminated in many ways the consequences of inadequately investing in our State’s infrastructure. It also points to potential improvements that should be made in policies, procedures, funding, and regulations. The ongoing investigations and reviews will analyze and provide recommendations in those areas and others. We are eager to see them. As you will read, EGLE continues, as we have since the moment the dams failed, to work with local, state, and federal partners to help the affected communities recover from their losses. We cannot overstate the extent to which the emergency preparedness planning and swift action from first responders helped prevent more disastrous outcomes. Public servants at all levels worked incredibly fast to fight back in every way possible and protect the community. This was apparent in the long hours—through the night and over multiple days—put in by the emergency teams. We saw it from the wastewater treatment plant operators staying with their machinery as long as they possibly could until the rising flood forced them to leave their posts.

As a free-market think tank, the Mackinac Center is guided by its belief in free markets, individual liberty, limited government and the rule of law. Founded in 1987, it is headquartered in Midland, Michigan. For more information, visit www.mackinac.org. 1 The 2020 Midland County Dam Failure Introduction Over 2,500 homes and buildings were damaged by flooding in mid-Michigan on May 19, 2020, when an aging dam failed on the Tittabawassee River, causing the cascading failure of a second dam immediately downstream. Initial reports indicated that as many as 150 homes and businesses were damaged beyond repair. Approximately 11,000 residents were hurriedly evacuated ahead of the flooding that caused as much as $200 million in damages. Fortunately, no deaths or serious injuries were reported. In any other year, the choices made by Boyce Hydro Power, the owner of the failed dams, and state regulators, working in the Department of Environment, Great Lakes, and Energy, might not have led to the failure of the Edenville and Sanford dams. But a major rainstorm compounded the regulatory and financial storms facing Boyce Hydro, and, together, these factors stressed the dams beyond their breaking point. The Edenville Dam had survived heavy spring flooding in the past.

The Village of Sanford lies on the extreme southwest shore of the impoundment, near the impoundment's dam outlet. Sanford Lake is a 1250-acre impoundment of the Tittabawassee River. Sanford Impoundment is also bisected by US10 at the southern end. Sanford Dam is the last in a series of four large hydropower dams on the Tittabawassee. Boyce Hydropower, LLC, formerly Wolverine Power, owns and operates the hydroelectric dam at the lower end in the Village of Sanford. Built in1925, the dam has a height of 36 ft., a hydraulic head of 26 ft., a controlled crest length of 1,579 ft., and a spill width of 139 ft. There is no fish ladder on this dam or any of the dams upstream. Fish do pass downstream over the gates to some extent. The outlet to Sanford Lake is at the dam, through the Tittabawassee River, to the Saginaw River and eventually to Saginaw Bay. Sanford dam was licensed under FERC in 1987, but amended to be included for relicensing with the upstream 3 dams in 2028. There is a minimal flow requirement for downstream release of 210 ft3/s, except during the walleye spawning season when there is a 650 ft3/s minimal flow requirement. There are many small drainages and the main Tittabawassee, which inlet to the lake.
