Annual monitoring is performed by contract scuba divers and the CA State Parks Dive Team to detect and remove any invasive aquatic weeds in Emerald Bay. Emerald Bay was infested with Eurasian watermilfoil and curly-leaf pondweed starting in 2007 and after implementing a removal project that was completed in 2015, this monitoring program was designed and implemented to continue the effort to keep invasive species from establishing in the bay. There is no completion date for this project. It will continue indefinitely.
See project 01.03.01.0041 - Emerald Bay Aquatic Invasive Plant Control for most recent information.
