Water Hyacinth Invades Modesto’s Tuolumne River

     Near the 9th Street Bridge in Modesto, California, water hyacinth has begun to blanket the Tuolumne River. Able to double its population in as little as two weeks, water hyacinth is  one of the state’s fastest growing invasives. “It looks like you can walk across it,” said Jenny Kenover, Modesto Council member, referring to parts of the river located near the bridge. With low water, high heat and an excess of nutrients, the hyacinth has found an ideal habitat, prompting local worries over its effects on salmon, insect populations and water quality.
