In danger of failure’
Water leaking through levee at 40 gallons per minute

Marshall Alexander, vice-president of Lakeshore
Garden Drainage District, Ken Thompson of the Army
Corps of Engineers, and Bill Cox also with the
Lakeshore Garden Drainage District, assess the
largest seepage area along a levee that protects a
number of homes along Lakeshore Drive Monday.
Two leaks were identified last week in the 81-year-old levee between Upper Klamath Lake and a drainage ditch, and two additional spring-like leaks were discovered over the weekend.
Currently, the leaks are moving about 40 gallons of water per minute from Upper Klamath Lake into a ditch on the other side of the levee, owned and maintained by the Lakeshore Gardens Irrigation District.
“I think it’s in danger of failure,” Norris said.
The Water Resources Department
recommended constructing an eight-foot wide and
180-foot long stabilization berm and drainage
blanket to mitigate the leaks.
W and H Pacific and Valley Pump had equipment
staged at the marina in case of a failure over
the weekend.
Local officials, homeowners, engineers, a
representative from the U.S. Army Corps of
Engineers and Norris inspected the levee on
Monday and discussed what action to take.
U.S. Army Corps of Engineers representative Ken
Thompson said he wouldn’t be able to sleep at
night if he lived near the levee for fear it
would fail and flood his home.
There are a dozen structures at risk, impacting
10 families. Many homeowners attended the Monday
meeting.
“We’ll get this problem solved,” said homeowner
Bill Cox.
Thompson suggested sandbag dikes be built around
the areas where the leaks are to prevent further
erosion as a quick and temporary solution.
A more permanent solution would be to build a
berm, Norris said. He suggested the vegetation
on the levee be stripped, laying down sand, a
filter fabric and drainage rocks. The most
expensive material is the rocks, which could be
more than $4 per yard, contractors estimated.
“I recommend it’s done where you’ve got those
leaks now,” Norris said.
Because it could be expensive, he further
recommended that additional sections of the
nearly mile-long levee be done each year.
The Klamath County Commissioners approved
using $20,000 from the risk management fund to
help with the leaks.
As of Friday evening, it was undetermined how
additional money would be raised for the
project. The drainage district is a taxing
district with 67 members, but has only about
$2,000.
Klamath County Emergency Services manager Bill
Thompson will soon receive bids for the project,
which is exempt from the county’s official bid
process because of the immediate need for
repairs
