Overview

Basics

Basics
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.

04/03/2024 10:51 AM Beth Vollmer Removed performance measure accomplishments for 2023 because they are being reported under project 01.03.01.0041 Emerald Bay Aquatic Invasive Plant Control (TRCD). Acres of Invasive Weeds Inventoried =6, Acres of Invasive Weeds Treated=0.3.
01/11/2024 1:22 PM Angelique Carl see project 01.03.01.0041 - Emerald Bay Aquatic Invasive Plant Control for most up-to-date information.
"Zero to few aquatic invasive plants had been detected in Emerald Bay since 2014, until recent surveillance monitoring in 2022 revealed AIP that required a higher level of work that was no longer considered a rapid response action. Dedicated treatment includes diver-assisted suction removal and hand-pulling. To ensure the long-term effectiveness of this work, routine surveillance monitoring will occur, and training of California Department of State Parks divers to conduct annual monitoring and removal of any emerging aquatic invasive plants.”

01/03/2020 2:58 PM Ashli Lewis In 2019, we found 160 stems of milfoil during the above surveillance. The contracted dive team came in and did most of the control work but our staff spent $1400 on hand removal of weeds and coordination with control crew for access and planning.
