Water infrastructure budgets to see massive cuts in 2012. 4/4/2011, Homeland Security Newswire
Next year water infrastructure projects and programs are expected to see massive budget cuts as
President Obama has proposed slashing infrastructure spending at the EPA and USACE. The Corps will
lose almost $1 billion, primarily from reductions in water infrastructure programs. States worry that
cuts will make it difficult to fund future infrastructure upgrades, and reports have shown that the US
faces a $500 billion shortfall for water infrastructure funding over the next twenty years.

Leaky Missouri levee highlights national problem, AP, 4//27/2011
A 2009 USACE survey identified 114 levees in 16 states that were "unacceptable for operations and
maintenance. The US is home to nearly 100,000 miles' worth of private levees. Congress passed the
National Levee Safety Act in 2007 and directed the Corps of Engineers to account for all private
levees, but no money was provided for the task.

Vermont
State to drain Sweet Pond. 3/30/2011, Brattleboro Reformer
State forestry officials have laid out plans to drain a Guilford pond after the site's dam was deemed a
potential hazard. The department has not arrived at an answer as to whether it should be removed or
replaced. Officials with the state's Department of Forests, Parks & Recreation, which owns the dam,
will begin draining the pond soon. Parks representatives have already begun the process of seeking
potential funding. According to the DSS Facilities Engineering Division, recent projects ranged from
$30,000 to $50,000 for the actual deconstruction.

Virginia
Property owners to fund spillway. 3/28/2011, Northern Virginia Daily

Bethel Island leaders worry about condition of levee as money runs dry. 4/2/2011, San Jose Mercury
News
Appx. 2400 ft of the Bethel Island levee, the only protection the Delta island has from flooding, is
either 8 ft tall or only 12 ft wide at the top. CA requires levees to be 11.2 ft above sea level and 16 ft
wide at the crown. The managing district in charge of the levee will most likely try a second time to
persuade voters to approve a parcel tax to repair it. Measure X, which failed earlier, called for an
annual tax of $252.29 on every parcel except those that are located completely underwater. Of Bethel
Island's 1822 parcels, 222 would have been exempt.

Capturing river water with dams in California faces problems. 4/8/2011, ScrippsNews
The price of water from new dams carries much of the burden to repay construction cost, as critics
fear water will be prohibitively expensive. This is the concern with two large projects: Temperance Flat
on the San Joaquin River; and raising Shasta Dam ($ 1 billion) on the Sacramento River. There are
however, exceptions such as Vaqueros Dam ($118 million), a project funded by ratepayers.

450 dams have been taken down nationwide since 1999, including 60 in 2010. As dam removals
continue, the focus has shifted from environmental restoration to public safety. Other dams
mentioned: Avalonia, Kennebec River, Rutan dam, Penobscot River, Eightmile River, East Haddam,

Plans Change for Levee Fix. 4/8/2011, WTHI - Terre Haute
Last month's Bennington Levee break sent the White River flowing over 8,000 acres of farm ground.
The county has been unable to get any federal or state assistance to fix it; officials say county's $1.4
million "rainy day fund" will be enough to fix Bennington Levee and another break along the Prairie
Creek Levee, but not to cover an additional $1-million for temporary repairs that would allow farmers
to plant this year's crops.

Floods force evacuations in Indiana, Kentucky and Missouri. 4/22/2011, WTHI - Terre Haute
Water rolls in through a break in the Bennington Levee that the county has been unable to get
repaired. Officials say the break in the southern part of the levee should serve as a relief valve and
limit the amount of flooding upstream. The river is expected to run a foot and half higher than it did
when the levee gave way last month and officials here have already given warning to the people in the
area.

Iowa
Sensors monitor flood threats. 4/5/2011, WCF Courier
Sensors developed by the Iowa Flood Center use sonar to measure the distance from a bridge to the
surface of a body of water running beneath. The sensors, installed on 50 Iowa bridges in a joint
project between the Center and the Iowa DNR, send reports every 15 minutes to a database at the
center's headquarters on the University of Iowa campus. The sensors supply more limited data than
those overseen by USGS, but at $3500 apiece (plus a $30 monthly cell phone charge) are less
expensive and require almost no maintenance.

Activists fight to stop dam across Mekong. 4/8/2011, AP
A plan for the first dam across the Mekong River (Xayaburi dam) has set off a major environmental
battle in Southeast Asia. Construction would lead to the resettlement of up 2,100 villagers and impact
tens of thousands of others. Estimated cost $3.5 billion.

China (Also included: Japan)
Lawrence Solomon: Dams are worse. 4/2/2011, Energy Probe
Executive director of Energy Probe claims the most dangerous source of electricity belongs to major
hydroelectric dams (not nuclear power), mentioning the catastrophic failures of the Banqiao and
Shimantan dams in '75. While deaths from nuclear accidents are rare, those from dams are not. Italy
lost 2000 people in a '63 dam failure, France 400 in '59. The Chinese government claims 40% of its
dams are at risk. If the Three Gorges dam failed, the tsunami created could precipitate the world’s
largest man-made disaster, with a death toll in the millions.

Southeast Asian Nations to Discuss Laos Dam. 4/18/2011, Wall Street Journal
Thailand, Vietnam, Cambodia and Laos are expected to meet in Vientiane to debate and possibly
decide whether Laos should proceed with the $3.5 billion Xayaburi dam. Laos hopes to use revenue to
drive economic growth in one of the world's least-developed countries. Environmentalists and some
government officials say the project will damage downstream fishing areas—a major worry given the
rising anxiety over food security in Asia—and force some residents to abandon river communities. It
could also set a precedent for further development on the Mekong. Other dams mentioned: Nam
Theun 2 (Laos).

Sri Lanka
Sri Lanka dam safety confab gets Dutch expertise. 4/4/2011, Lanka Business Online
Dutch expert will lead forum on disaster risk organized by LirneAsia, a regional policy research body
that has been active on improving dam safety policies in Sri Lanka, which has 12,000 small dams and
350 medium and large dams. LirneAsia says more needs to be done in funding dam maintenance and
safety. Authority over dams is highly diffuse with multiple ministries and entities having responsibility
for dams in the same river system. In 1986, a large dam in Kantale was breached costing 176 lives.
Options to manage risk include making inundation maps public and using insurance. In Holland
climate change is also being factored into Dutch policy.

Twenty five years after Kantale: Have we learned?. 4/6/2011, Daily Mirror
Kantale dam breached in April 1986, costing 176 lives, $590,000 in relief, and almost $1.7 million in
repairs. Sri Lanka has 12,000 small dams and 350 medium and large dams. Of these, 200+ small
dams breached in the successive floods of 2011 and greater tragedies were avoided by emergency
action on larger dams. On April 27th, an expert on dam safety policies in the Netherlands, Dr Aad
Correlje, will lead discussion at the 2nd LIRNEasia Annual Disaster Risk Reduction Lecture and
Response Session.
