Mass of hyacinths leaves many boaters frustrated
STOCKTON -- Tangles of green water hyacinth floating atop channels in the San Joaquin Delta have exploded to life under this summer's heat, creating headaches for local boaters who just try to steer clear of the stuff.
"It's like you're navigating through somebody's green lawn," Roman Oren of Rocklin said Wednesday morning as he worked on his 35-foot cruiser, moored at Ladd's Stockton Marina.
Oren and other Delta boaters leery of floating logs camouflaged under the hyacinth have to slow their boats to a snail's pace while travelling through hyacinth clumps. Or they steer around it altogether.
"The other day, it looked like you could walk across it," Oren said.
Nearly every year since 1982, the state's Department of Boating and Waterways has battled the hyacinth and other water weeds by spraying herbicide on choked areas of the Delta. Spraying is expected to continue until November.
Aside from annoying boaters, the hyacinth starves oxygen from water, hurting fish and plant life native to the Delta. It clogs marinas built in stagnant channels and irrigation systems that draw Delta water.
"In some places, it's worse this year and in some it's better," said June Iljana, a spokeswoman for the Department of Boating and Waterways.
A state crew sprayed herbicide in marinas skirting Stockton in recent weeks. Some flowering hyacinths have wilted and started to rot in the water, while other patches continue to thrive.
"It's certainly rearing its head," said Bill Jennings, chairman of the California Sportfishing Protection Alliance.
Jennings said hyacinth is only one of several exotic species of plants that found their way into the Delta.
Egeria densa, a garlandlike plant that's not native to the Delta, reaches up and wraps around boat propellers.
Jennings, who said he's been caught up in egeria densa more than once while boating in the Delta, urged greater regulation to control importing exotic species.
"Hyacinth will quickly become the least of our problems in the Delta," he said.
