The Fall Flood of
During the later days of August and throughout all of September
2010, the Porter area received excessive amounts of rain. Nearly
15 inches of rain fell within Porter and areas south during this
time, leaving the ground soaked and completely saturated. In
Porter itself the ground felt like a sponge, and simply mowing
your lawn with a riding lawn tractor would leave divots in the
yard that would soon "pop" back out after a day or so. During
the week of September 20, it was reported on
www.portermn.org that the
town was fairing well thus far and even after a very wet spring
and summer, basements in Porter were not seeing any water with
the August and September rains.
On September 21 it was reported that the Yellow Medicine River in
Porter was running swiftly, but no more than 1 to 2 feet higher
than normal flow. It was then on the afternoon of September 22
that it began to rain very heavy. By the morning of September 23
it was reported that the Yellow Medicine River had rose nearly 8
feet over night. By noon on Wednesday the City's sanitary sewer
system began to fail, putting raw sewage into Porter resident's
basements, but to worsen matters the Yellow Medicine River also
spilled its banks on Porter's south side and water began rushing
into the old city dikes and filling a garage of a home built on
the old dike.
As sandbagging began it was noted that all three retention dams
south and west of Porter were full to capacity with both Porter
Lake (Dillon Pond) south of Porter and Lake John west of Porter
discharging water over the emergency spillways. By 2:00 MNDOT
was stopping and directing traffic on the west side of Porter as
water rushed through the old skunk creek, which is typically
nothing more than a drainage ditch that rarely has running
water, rushed with heavy currents and spilled its banks flooding
the west part of the Porter Elevator and then running over
Highway 68 at Prairie Avenue with a heavy current.
As the day went on the Yellow Medicine River continued to rise and
started to breach the levies on Porter's east side. Water began
to come up into the yards at SMI where a temporary levy
construction and sandbagging took full-force. SMI loaded
valuable equipment in their buildings and yards onto flat bed
semis to protect anything they could from the rising water. Levy
breaches were also reported behind residences on Sunrise Avenue
as water spilled over the levies from the river and began
threatening those homes.
In an initial report to the FEMA it was reported that nearly
$200,000 in damage was being claimed in city of Porter. Cleanup
continued in Porter for weeks and months to follow the flood.
Flood waters begin to immerse the Syltie
residence on South Brook Avenue as the Yellow Medicine River
left its banks on Porter's South side.
A sandbag dike is constructed at the Syltie
Residence so water can be pumped from the house.
Entering Porter on the East side of town, the
Yellow Medicine River is approaching the top of the city levy's
as water rushes out of the river valley and flows east down the
ditches of Highway 68.
The old red barn on Highway 68 on Porter's
east edge goes under water.
Water begins to rush eastward through the
ditches of Highway 68 as water spills the river banks before
going under the Highway 68 bridge.
The river approaches the Highway 68 bridge
where it begins to spill over levies in all directions.
