Crumbling Infrastructure: $36 billion needed to fix nation's dams;
$10.1 billion for 'most critical' structures

Lexington, KY 11/10/2003
According to the American Society of Civil Engineers (ASCE), our
infrastructure is falling apart. Nowhere is the deterioration of
infrastructure more apparent than in our nation's dams.
In response to these concerns, the Association of State Dam Safety
Officials (ASDSO) has compiled state and national estimates of the
cost of dam rehabilitation. In the coming year, ASDSO will ask Congress
to establish a national dam financing solutions program.
A nine-member task committee of ASDSO has concluded that the cost
upgrading or repairing all of our nation's non-federal dams would
exceed $36 billion.
The committee's report, The Cost of Rehabilitating Our Nation's
Methodology, Estimate and Proposed Funding Mechanisms, states that
almost one-third of this amount - $10.1 billion - is needed for
the nation's most critical dams, those whose failure would cause
loss of human life. The
states currently regulate more than 10,000 of these "high-hazard-potential"
structures, and this number is increasing.
ASCE's 2003 Progress Report for America's Infrastructure, released
September, judged dams as being in worse condition than reported
two years ago. As dams merited a grade of 'D' on the 2001 Report
Card for America's Infrastructure, their continued deterioration
is valid cause for concern, if not alarm.
In the past two years, at least 21 dam failures have occurred in
The May 2003 failure of Silver Lake Dam, in Michigan's Upper Peninsula,
caused the failure of downstream Tourist Park Dam and the evacuation
of more than 1,800 people in the city of Marquette. The failures
resulted in more than $100 million in damage, including about $10
million damage to utility facilities, $4 million in environmental
damage and $3 million to roads and bridges. Twenty homes and three
businesses were damaged or destroyed. The We Energies power plant,
which generates half the electricity produced in the Upper Peninsula,
was flooded, causing the closure of two nearby iron mines, and the
layoff of about 1,100 mine workers for several weeks, until the
power plant was repaired. The mine owner estimated that the shutdown
cost the local economy about $1 million a day.
Also in May, several dams failed in North Carolina, causing the
of approximately 75 homes and damages estimated at $12 million.
The state is spending nearly $5 million to rebuild the Hope Mills
dam, which provides a critical stream crossing.
For the past 20 years, ASDSO has worked to prevent such calamities.
Association has been instrumental in the passage of dam safety legislation
in the U.S. and in the establishment and strengthening of state
programs. However, ASDSO has long recognized that financial constraints
on dam owners limit the effectiveness of state programs.
Well over 50 percent of U.S. dams are privately owned; state and
governments, federal agencies and utilities own the remainder. Most
owners are not wealthy and even those who possess considerable financial
resources are often overwhelmed with the staggering costs of dam
maintenance, repairs and upgrades.
"Maintain 'em or drain 'em," a motto adopted by the National
Dam Safety Program, aptly expresses the dam owner's dilemma. Faced
with the choice of repairing or upgrading a dam, or the less expensive
draining a lake, many owners choose the latter course; however,
where dams provide drinking water or flood control, dam removal
may not be a viable alternative.
The loss of a reservoir of any size often has negative economic
impacts on local communities that have depended upon the impoundments
created by dams for water supply, recreation and flood control.
function of flood control has become increasingly important in recent
as more and more development has occurred in historic floodplain
protected by dams. As these dams deteriorate, they should be fixed
replaced, as dam removal leaves property in downstream floodplains
vulnerable to flooding.
Dam owners faced with either option-dam repair or dam removal-often
need financial assistance. In order to estimate the magnitude of
ASDSO established a nine-member task committee to develop a reliable
estimate of the national cost of dam rehabilitation.
The committee's intensive two-year, peer-reviewed study considered
number of state-regulated dams, the size of the dams, the costs
of deferred maintenance (any maintenance activity that does not
require formal engineered plans or the approval of a professional
engineer), the cost of engineering evaluation and design, the cost
of rehabilitation (whether repair, replacement or removal) and the
cost of increasing storage capacity or structural upgrades. Estimates
do not include costs for administration of a funding mechanism;
nor do they take into account the increasing number of high-hazard-potential
The task committee has recommended the creation of a national dam
rehabilitation loan program. ASDSO has worked with lawmakers to
legislation that provides funding for repairs to high-hazard-potential
and is currently seeking a sponsor for the legislation.
Commented ASDSO Legislative Chairman, Brad Iarossi, "Congress
just approved a bill that allocates $18.6 billion toward infrastructure
Iraq, including $125 million for dam construction and repair. Is
infrastructure less of a priority? Our lawmakers should also be
with the poor condition of U.S. infrastructure, which currently
our safety and well-being."
The ASDSO report notes that many states cannot afford to wait for
a national funding program; thus, it provides guidelines for establishing
revolving loan funds for dam rehabilitation, repair and removal.
federal loan programs could then supplement these state funding
mechanisms. Funding programs for dam repairs now exist in fewer
than a dozen states, but ASDSO is working to improve this situation.
On November 4, New Jersey voters approved a dam rehabilitation funding
bill that provides $15 million to pay for state projects and $95
low-interest loans to private and municipal dam owners. John Moyle,
Manager of the New Jersey Dam Safety and Flood Control Section,
noted, "Having an effective program requires not only staff
and a strong enforcement program but also a dam repair funding mechanism
for dam owners. The funding mechanism is a win-win situation since
it provides assistance to the owners, stimulates the economy by
providing jobs and protects our citizens from potential dam failures."
Raul Silva, co-chair of the ASDSO task committee, applauds the New
Jersey initiative, and hopes that federal lawmakers will take the
"When public safety is an issue, the federal government often
proactive approach to repairing other elements of the national
infrastructure," emphasized Silva. "Unfortunately, dams
have not gotten
this kind of comprehensive attention, maybe because they're usually
built in out-of-the-way locations and they're not something that
people actually see and use directly in their daily lives. But the
benefits that dams provide
are tangible and the risks posed by dams that are not properly maintained
and repaired are real."
"For a long time, we in the profession have said that inspections
not enough to make dams safe; that dam owners facing expensive maintenance
and repairs need financial help. Now, for the first time, we have
a realistic answer to the question, how much will it take to fix
the problem?" said Silva.

education, and communication.
