May became the month that plunged the
area into a historic drought situation.
The D3 status (Extreme Drought) on the
U.S. Drought Monitor was retained for
the entire month. Area rivers remained
at baseflow, and some reached
historically low streamflows, the
lowest recorded for this time of year
in more than 50 years. Farm ponds
experienced lowered levels as well.
Some smaller creeks which typically
would have water in them after a wet
Spring are reported to be dry. Lake
levels were below normal, including
Tims Ford Lake. Mandatory water
restrictions were placed into effect
in Winchester, Tennessee. Soil
moisture was at historic lows, at the
first percentile or below. Hay cutting
ran behind and at a lower production
rate. Non-irrigated com in some
areas was believed to be a complete
loss. Overall yields were reduced and
the dry conditions caused even further
reductions in the expected yields.
Local extension agents rated the com
and wheat crops as poor to very poor.
Extension agents also reported that
cotton and soybeans were stressed due
to lack of soil moisture. Pasturelands
produced very low yields of hay due to
lack of growth, thus farmers have been
forced to reduce cattle herds.

water in their basements. Basement water
levels ranged from a few inches to very
deep water all the way up to the first
floor of homes. Several homes had
basement walls that collapsed. The
overwhelming load on the drainage
system caused sewage to back up
into many homes. The National Guard
brought large generators and pumps to
Aberdeen to alleviate pressure on the
storm system. A school in north Aberdeen
was closed for several days because in
was surrounded by water. Also, many
vehicles stalled on the roads and power
outages occurred, mainly in northern
Aberdeen, as transformers went under
water. Many cars were also damaged by
the flooding. Over thirty families in
Aberdeen were displaced from their
homes with many living in
emergency shelters.
Over one-hundred homes in Aberdeen were
condemned with nearly fifty considered
as unlivable. Thousands of acres of
crops were flooded and damaged with many
seeds and large quantities of fertilizer
washed away.
An emergency operations center was

Widespread flooding continued across much
of Brown county through May 8th. Most of
the cities affected included Aberdeen,
Warner, Columbia, Hecla, Groton, Barnard,
Bath, and Stratford. Several hundred
homes, some businesses and countless
roads were affected by the flooding.

damage, especially the north side of
Aberdeen. Seventy-five percent of the
homes in Aberdeen received some water in
their basements. Basement water levels
ranged from a few inches to up to the
first floor of homes. Several homes had
basement walls that collapsed. The
overwhelming load on the drainage
system caused sewage to back up into
many homes. The National Guard brought
large generators and pumps to Aberdeen
to alleviate pressure on the storm
system. A school in north Aberdeen was
closed for several days because in was
surrounded by water. Also, many vehicles
stalled on the roads and power outages
occurred, mainly in northern Aberdeen,
as transformers went under water. Many
cars were also damaged by the flooding.
Over thirty families in Aberdeen were
displaced from their homes with many
living in emergency shelters.
Over one-hundred homes in Aberdeen were
condemned with nearly fifty considered as
unlivable. Thousands of acres of crops
were flooded and damaged with many seeds
and large quantities of fertilizer washed
away.
An emergency operations center was
operated in Aberdeen for several days to
coordinate all emergency activities.
Hundreds of volunteers helped with the
cleanup. Over 2500 tons of flooding
debris was taken to the landfill in
Aberdeen. The Governor was in Aberdeen
and declared a state of
emergency for Brown county.

Columbia also had flooded homes and
basements. Thirty percent of Columbia's
homes had some water in them with two

May became the month that plunged the
area into a historic drought situation.
The D3 status (Extreme Drought) on the
U.S. Drought Monitor was retained for
the entire month. Area rivers remained
at baseflow, and some reached
historically low streamflows, the
lowest recorded for this time of year
in more than 50 years. Farm ponds
experienced lowered levels as well.
Some smaller creeks which typically
would have water in them after a wet
Spring are reported to be dry. Lake
levels were below normal, including
Tims Ford Lake. Mandatory water
restrictions were placed into effect
in Winchester, Tennessee. Soil
moisture was at historic lows, at the
first percentile or below. Hay cutting
ran behind and at a lower production
rate. Non-irrigated com in some
areas was believed to be a complete
loss. Overall yields were reduced and
the dry conditions caused even further
reductions in the expected yields.
Local extension agents rated the com
and wheat crops as poor to very poor.
Extension agents also reported that
cotton and soybeans were stressed due
to lack of soil moisture. Pasturelands
produced very low yields of hay due to
lack of growth, thus farmers have been
forced to reduce cattle herds.

TNZ076-096-097 Moore--Lincoln--Franklin
Drought
May became the month that plunged the
area into a historic drought situation.
The D3 status (Extreme Drought) on the
U.S. Drought Monitor was retained for
the entire month. Area rivers remained
at baseflow, and some reached
historically low streamflows, the
lowest recorded for this time of year
in more than 50 years. Farm ponds
experienced lowered levels as well.
Some smaller creeks which typically
would have water in them after a wet
Spring are reported to be dry. Lake
levels were below normal, including
Tims Ford Lake. Mandatory water
restrictions were placed into effect
in Winchester, Tennessee. Soil
moisture was at historic lows, at the
first percentile or below. Hay cutting
ran behind and at a lower production
rate. Non-irrigated com in some
areas was believed to be a complete
loss. Overall yields were reduced and
the dry conditions caused even further
reductions in the expected yields.
Local extension agents rated the com
and wheat crops as poor to very poor.
Extension agents also reported that
cotton and soybeans were stressed due
to lack of soil moisture. Pasturelands
produced very low yields of hay due to
lack of growth, thus farmers have been
forced to reduce cattle herds.
