Christopher Potter and David Bubenheim (SGE) are delivering maps and tabular summaries of live water hyacinth coverage in waterways of the Sacramento-San Joaquin River Delta from the latest cloud-free Landsat satellite imagery. Currently the Delta may be the most extensively invaded estuary by exotic plant species in the world. Water hyacinth is considered to be one of the primary invasive weed problems in Delta waterways: its prolific floating biomass interferes with pumping equipment for agricultural water supply and recreational activities such as boating and fishing. Excessive water hyacinth biomass may alter water quality and provide habitat for undesirable disease-carrying insects. Using Landsat imagery as of mid-July 2015 the total estimated acreage of water hyacinth coverage has increased on Delta waterways by about 92 acres (12%) since mid-June 2015. This is mainly on the Old River, San Joaquin River, and the False River. These Landsat image products are shared widely and used by partners at the USDA, U.S. Bureau of Reclamation, California Department of Parks - Boating and Waterways, and many other state and local agencies to help plan controls on weed biomass growth in all Delta waterways. This remote sensing applied science that spans the western U.S. and Hawaii is funded entirely by the USDA and represents NASA Ames’ most important and recognized collaboration with USDA.
