Levee Maintainer, Dredge
Barge
David Talley
I’m Captain and Head Leverman
of the Mallard, a sidedraft clamshell dredge used to
maintain the levees that enclose the salt ponds of San Francisco
Bay.
I came here in 1988. The 200
miles of levees I’m responsible for run, starting in the East
Bay, from the San Mateo Bridge all the way around the South Bay
and back up to Redwood City.
My shift starts Tuesday morning
and goes through Friday night. I drive down from Corning where I
live, 210 miles and 3 ¼ hours away. I’m 41 years old and can
retire with full benefits at 55, but I probably won’t.
The Mallard has no
propulsion system whatsoever. I maneuver it by using the dredging
bucket to pull me where I need to go. It’s like casting a
fishing reel. The Mallard is the last wooden hull
sidedraft dredge on the Bay.
My work is important for many
reasons, one big one being the need to keep the salt water in the
ponds from getting into the Bay. There never has been a breech, or
break in the levee since I have been on board, and I mean to keep
it that way.
I have to be careful of the
high power lines that cross the Bay bringing Hetch Hetchy power
into San Francisco. My biggest concern is the endangered wildlife
I see out here. The Salt Marsh mouse lives in the pickleweed. The
Clapper Rail is a chicken-like bird, the Snowy Plover looks like a
bit of white foam and the Least Tern teaches their young to fish
in the salt ponds. I also watch out for the harbor seal, and
report what I see to Cargill management and the U.S. Fish and
Wildlife Service.
I live on the Mallard
during the work week. It’s just the birds and me. It’s so
quiet at night that I can hear the waves lapping and the boat
creaking. During the day I go from pond to pond to top the levees,
chopping my way through where I need to and closing up the levee
behind me once I’m in.
