Dead River Frequently Asked Questions
Updated January 2004
On May 14, 2003, a dike at Silver Lake in Marquette County was
breached, releasing the reservoir into the Dead River system.
Following are the answers to some questions that are asked quite often.
If you have a question that is not answered here, or if you'd like further
information, contact us.
- What caused the breach in the dike at Silver Lake?
- Initial studies indicate a failure in a fuse plug and its
foundation was due to improper design. The dike that washed out was a
"fuse plug spillway," which is designed so that part of it will release
and allow a limited amount of water to flow out of the reservoir when
the reservoir water level gets too high. These specially designed dikes
are intended to protect the remaining portions of the dam. However, at
Silver Lake, a greater portion than anticipated gave way.
- In what condition are the Hoist and McClure Dams?
- The floodwaters caused some damage that must be repaired,
but state and federal officials and private companies inspected the Hoist
and McClure dams after the flooding and determined that they are still
safe.
- Is the Dead River safe?
- In January 2004, the company began drawing down the Hoist
reservoir in preparation for spring run off. This could result in unstable
ice conditions, and the public is being cautioned to stay off the reservoir.
- Who is responsible for debris cleanup?
- According to state law, the riparian landowner is responsible
for deciding if debris should be removed. Work in a waterway or wetland
requires a permit from the Department of Environmental Quality. Contact
Joan Duncan at 346-8300.
- Has UPPCO done anything about environmental recovery along the Dead River?
UPPCO has hired an environmental consulting firm and
has been working with the Michigan Department of Environmental Quality,
the Michigan Department of Natural Resources, and other federal, state,
and local agencies to mitigate any environmental impact to the Dead River.
For an expanded answer, please review the following news releases:
- What can private property owners do to correct erosion caused by
high water, and who pays for the effort?
- The Central Lake Superior Watershed Partnership and the
Natural Resources Conservation Service can provide advice on sedimentation and erosion control.
The watershed partnership number is 226-2461. The NRCS number is 226-8871. At this time, no
public funds are available for this effort.
