STOCKTON, Calif. (AP) - Port officials in Stockton have removed hundreds of thousands of pounds of an invasive plant that has clogged their waterway and other waterways and harbors in the Sacramento-San Joaquin Delta.
The Record of Stockton reports that more than 375,000 pounds of water hyacinth have been removed from the Stockton Deep Water Channel in the past several weeks.
Port officials are trying to avoid a repeat of last year, when ships stopped navigating the channel at night because they could not differentiate land from mats of hyacinth.
Port officials say a state spraying program failed to control the hyacinth, so they hired a Bay Area company to remove it.
When left unchecked, water hyacinth forms a solid carpet across the water surface that can clog propellers, rudders and water intakes.
