Libby Dam flow increased
|
|
May 1, 2013 |
Current Koocanusa Reservoir elevation is 2403.0
feet.
Current Koocanusa Reservoir inflow is ~13 kcfs.
Current Libby Dam outflow is 13 kcfs.
Between 9 and 11 a.m. today (MST), discharge
from Libby Dam increased from nine kcfs to 13
kcfs. The current discharge of 13 kcfs will be
held throughout the day today and tomorrow.
On April 29, the Army Corps NW Division
Hydrologic Engineering Branch declared that the
Start of Refill for Libby Dam would begin on May
1.
The April 2013 April-August water supply
forecast for Libby Dam was 6189 KAF (thousand
acre-feet), which is ~105% of the 30-year
average from 1980-2010. The May 2013
April-August inflow forecast is expected to
increase by 200 - 300 KAF.
VarQ flow is currently ~17.5 kcfs, but will be
recalculated when a new water supply forecast is
issued later this week.
To avoid drafting the reservoir during refill,
the dam will continue passing inflow up to the
VarQ flow. We expect inflow to exceed VarQ flow
early next week, after which time releases will
be held at the VarQ level until the annual
sturgeon flow augmentation operation begins. |
