Mysterious Machine Dropped to the Bottom of Lake Hodges

It’s the only one of its kind in Southern California and no one will see it again for years.

“It’s a giant upside-down cone with some pipes,” said Jeff Pasek. “It’s a strange looking device.”

It’s a strange looking device called a Speece Cone that’s expected to improve the water quality at Hodges Reservoir near Escondido.

“It’s not going to be seen again for a number of years because it’s 70 feet deep in the reservoir,” said Pasek, a Project Officer with the City of San Diego’s Public Utilities Department.

The $3.4 million project will constantly inject oxygen into the reservoir which will reduce the nutrients that algae feed on, Pasek said.
