Early Detection for Non-Infested Lakes

Project Status: 
Current Status: 

(Updated August 29, 2017) - Staff coordinate with other partner agencies across the District to perform AIS early detection monitoring at public accesses. This typically involves checking a zebra/quagga mussel sampler plate, sampling aquatic vegetation with a rake and visually assessing the public access area for possible AIS.

About this project: 

High priority waterbodies will receive annual monitoring based upon the use-patterns, shoreline development and interconnectedness of those waterbodies, giving them a higher risk for an AIS infestation. Early detection of AIS allows for rapid response to an infestation and gives us a better shot at control efforts or possible removal.

Monitoring includes a weekly check of a boat launch sampler plate and shoreline, as well as a yearly snorkel survey at other high risk areas around the lake. Tow nets are also used to sample for zebra mussel veligers and spiny waterflea.
