Dam outflow decreased as more rain looms
|
June 6, 2012 |
With the Kootenai River level less than half an
inch below flood stage and more rain looming,
the Army Corps of Engineers scaled back outflow
from Libby Dam early this morning.
"Another very intense rainstorm is developing
tonight and should cause river levels to rise
fast in the Moyie, Yaak and Fisher Rivers," said
Corps engineer Joel Fenolio yesterday. "In
response, we are decreasing outflow from Libby
Dam tonight from 15kcfs to 12 kcfs over three
hours starting at 1 a.m. Mountain Standard
Time."
The decrease is expected to lower the level on
the Kootenai River at Bonners Ferry from its
current 1,763.57 feet to just over 1,762.5 feet,
through the coming week, thought tonight's
expected rainfall could raise the river level to
flood stage of 1,764 feet.
"The upcoming storm is forecasted to be more
intense and have longer duratyion than last
night's storm," Fenolio said. "We will monitor
this storm event through the night and make
additional flow reductions as necessary."
At 9:53 a.m. today, the National Weather Service
issued a flood watch and flash flood warning for
the Moyie River at Eastport.
Flood stage there is nine feet, and the current
level at Eastport is 8.71 feet. That level is
expected to reach 9.2 feet by 5 a.m. June 7. At
that level, lowland flooding can occur between
Eastport and Addie.
The National Weather Service, Spokane, predicts
up to half an inch of rain possible by tonight,
accompanied by winds steady at about 11 to 16
miles per hour, gusting to about 25 miles per
hour. The rain should taper off into tomorrow,
though the forecast continues to call for more
showers through the weekend before partly sunny
skies return on Monday.
Property owners throughout the area are
encouraged to keep an eye out for rising water
and to take steps to protect their property
before damage occurs. Sandbags and sand are
available for free to property owners at the
Hall Mountain Fire Station, at Copper Creek and
at the county road and bridge shop on U.S. 95
just south of Three Mile.
Boundary County Emergency Management incident
commander Bob Graham is keeping an eye on the
situation as it develops, but the county will
only step in to help in an emergency.
"A lot of this is up to the homeowners and their
neighbors," Graham said. "They know the area and
what to look out for, and know the steps that
need to be taken to protect their homes and
property."
Those concerned about imminent flooding can call
the sheriff's office at (208) 267-3151,
extension 0. If it appears that flooding is
going to threaten property in the Eastport area,
you can also call Hall Mountain Fire, (208)
267-7375.
