Aquatic Invasive Species (AIS) Contain and Control

Control pioneer populations of aquatic invasive species Prevent the spread of aquatic invasive species to unpopulated waters Control established infestations of aquatic invasive species and restore native aquatic species communities Provide research and demonstration that advances the state’s knowledge and understanding of aquatic invasive species control Ongoing maintenance to contain aquatic invasive populations within a waterbody

Examples Of Control Projects

Lake Nokomis Concerned Citizen's Inc.: Bridge Lake Aquatic Invasive Species Control & Prevention

Lake Nokomis Concerned Citizens (LNCC) is sponsoring an AIS Controlling Established Infestations grant on Bridge Lake in Lincoln County to be completed by December 31, 2012. This is a four year project that will focus on EWM management, and AIS education, prevention and monitoring. The goal is to reduce the treatable EWM to less than 10 acres. This will allow LNCC to continue management of AIS with minimal state financial assistance. Learn More

Black Otter Lake P & R District: Black Otter Lake Drawdown & CLP/EWM Control Project

The Black Otter Lake District proposes to control Curly-leaf pondweed (CLP) and Eurasian water-milfoil (EWM) through a drawdown, chemical treatment, hand removal, and preventative measures in Black Otter Lake during the period 2009 - 2011. The project elements and deliverables are specified in Black Otter Lake Districts' Aquatic Invasive Species Grant application, dated August 1, 2008. The project includes monitoring the extent and density of CLP and EWM annually through pre-treatment and post-treatment surveys of known infested areas, and monitoring other lake areas for the presence of aquatic invasive species (AIS); treating EWM infested areas with an aquatic herbicide; conducting hand-removal of CLP and EWM; water quality monitoring, and conducting volunteer activities to prevent further AIS infestations, including conducting watercraft inspections.
