COBB-HIGHLAND RECREATION COMMISSION: Blackhawk Lake EWM EPP

Purpose

The Cobb-Highland Recreation Commission plans to carry out recommendations of the previous Early Detection and Response grant for Eurasian watermilfoil by continued monitoring, education and prevention and planning. The milfoil has not been found in 2012 or 2013, but early detection and response will be critical to protecting the lake if it reappears. The main goals of preventing further introduction and spread of EWM and controlling any existing populations will be reached by updating the APM plan, monitoring and mapping of any existing EWM, training staff and volunteers to perform AIS and water quality monitoring, developing and implementing educational programs to prevent the spread of EWM and other invasives, and conducting a Clean Boats Clean Waters program. The activities include annual monitoring for milfoil using a variety of approved methods, and conducting workshops for schools and other groups. The final report will include maps, raw data and data summaries, and results will be presented via news articles, posters, and presented to professionals at conferences.

Blackhawk Lake in Iowa County, Wisconsin, is a 220-acre impoundment with a maximum depth of 45 feet. The lake is surrounded by public lands with a mostly wooded shoreline. Monitoring and rapid response with manual removal and herbicides to pioneer infestations of EWM helped control its spread in Blackhawk L. EWM has not be found since 2011. Competition from abundant curly-leaf pondweed and lush native vegetation inhibits its growth. Weather affecting water clarity also affects EWM distribution and abundance.
