The Klamath Basin Area Office of the
Bureau of Reclamation today announced that current extremely dry
conditions in the Klamath Basin have triggered letters to be mailed to
Klamath Project irrigation districts and individual irrigators
implementing the Upper Klamath Lake Watershed Plan (Drought Plan).
"The letters call for meetings between
Reclamation and the districts and individual irrigators to determine the
allocation of water deliveries on the Klamath Project in the event of a
drought," stated Dave Sabo, KBAO Area Manager. Sabo also requested that
the districts "contemplate a range of possible allocation scenarios that
could be implemented if a water supply deficiency materializes."
"Due to our analysis of the March 1
Natural Resources Conservation Service (NRCS) Klamath Basin Forecast,
which predicts hydrological conditions between April and September, we
need to begin now to plan the water deliveries to the Project," Sabo
acknowledged.
Sabo pointed out that the March 1 NRCS
forecast predicted Upper Klamath Lake inflow at 52 percent of average
for April through September.
"But, as of today, snow pack has
dwindled to 38 percent of average. Warm temperatures and dry conditions
will likely further reduce future forecasts," Sabo said.
Oregon Department of Water Resources
measurements of soil moisture show a continuing decline in levels over
the past 4 years. The downward trend is particularly noticeable in
upland areas away from human activities. These are the principal
ground-water recharge areas, and this is indicative that absorption of
snowmelt will continue, potentially reducing runoff throughout the
spring.
"The fall and early winter Upper
Klamath Lake inflows were considerably lower than last year's inflows,"
Sabo said. "Although early season snow pack and inflow forecasts were
extremely optimistic, runoff never materialized."
Sabo said that last week he called for
cooperation in the establishment of immediate conservation practices,
"and today's analysis of the hydrology makes it clear that we can't wait
another two weeks for the mid-month NRCS forecast."
Sabo said it's still early in the
season.
"I'm hopeful that conditions may
improve and that we will have an ample supply for all who depend on
river flows." |
