Cultural Aspects of Lakes

History Growing Off Your Dock: The Living Legacy of Wild Rice in Wisconsin

Wednesday, 8:00-8:50 am

This presentation will provide an overview of the cultural significance of wild rice to Native Americans and early European explorers, look at its long history of use in the state (continuing to today), and present some of the fingerprints this unique resource has left on our contemporary landscape.
Presenter: Peter David, Wildlife Biologist, Great Lakes Indian Fish and Wildlife Commission

Presentation: Manoomin - Wild Rice - History In Your Lake


People, Policy & Politics

Selecting the "Right" Lake Organization for Your Community

Wednesday, 8:00-8:50 am

The presentation will identify the pros and cons of lake associations, qualified lake associations, and public inland lake protection and rehabilitation districts as alternative models of lake governance. Case study based experience from various communities will be provided, using each type of organizational framework.
Presenter: Jeffrey Thornton, Regional Planner, SEWRPC

Presentation:  Organizational Options for Lake Owners


Aquatic Invasive Species

Rapid Response and Control of Policeman’s Helmet (Impatiens glandulifera)

Wednesday, 8:00-8:25 am

The first known Wisconsin occurrence of Policeman’s helmet (Impatiens glandulifera) has been reported in Shawano County. This incredibly invasive plant was originally planted as an ornamental species, and it quickly escaped captivity on the parent parcel. Strong evidence of deer herbivory and transport are documented in the area. An early detection response and eradication program was undertaken by a diverse collaboration of public and private entities due to the close proximity of State Natural Areas and tribal forests. We’ll cover the response protocols and how they were implemented around the infestation site during this presentation.
Presenter: Jon Motquin, Aquatic Invasive Species Coordinator, Shawano County

Presentation:  Rapid Response & Control of Policeman's Helment


Eradication of Ambitious Architects: The Red Swamp Crayfish (Procambarus clarkii) in three SE Wisconsin Ponds

Wednesday, 8:25-8:50 am

The red swamp crayfish, Procambarus clarkii, is a non-native crayfish species that was discovered in three ponds in southeast Wisconsin in the late summer and fall of 2009. Since the discovery, the Wisconsin Department of Natural Resources, along with local partners, has employed a multitude of containment, control, and eradication strategies. The complex burrowing abilities of the red swamp crayfish have proven to be a key factor in the failure of eradication attempts in 2009 and 2010. The red swamp crayfish has likely been eradicated from two of the three ponds based on physical manipulation activities conducted in the fall and winter of 2011. A full scale eradication plan will be implemented for this pond in the fall and winter of 2012. This presentation will focus on the eradication strategies utilized in the attempts to eliminate this invasive species from the fall of 2009 through the end of 2012.
Presenter: Heidi Bunk, Lakes Biologist, WDNR

Lake Habitat & Biology

Most Lakes Are Small: Data and Management Needs for Shallow Systems

Wednesday, 8:00-8:50 am

Most of the millions of lakes in the world are small and relatively shallow (<10 m in depth) and contrary to their deeper counterparts a large proportion of the lake volume is exposed to sediments and soils. Consequently, there is intense interaction between the lake water and the chemical and metabolic processes of the sediment. This presentation will highlight several studies/management plans and discuss data and management needs for shallow systems.
Presenter: Jeremy Williamson, Watershed Biologist, Polk County Land and Water Resources Department

Native Plants & Animals

Native Mussel Monitoring in Eau Claire County

Wednesday, 8:00-8:50 am

Beaver Creek Reserve has just finished a one year project to catalog the native mussels that are in Eau Claire County, Wisconsin. Come explore the wonderful world of native mussels and what lies below the water’s surface in Eau Claire County.
Presenter: Anna Mares, AIS Coordinator, Beaver Creek Reserve

Water Quality, Watersheds, & Groundwater

Using Aquatic Plant Surveys to Evaluate Lake Health

Wednesday, 8:00-8:25 am

Aquatic plant surveys are an underused method of evaluating the health of a lake and tracking changes in a lake. The results can also be used for several aspects of lake management. This presentation discusses ways regular aquatic plant survey results can be used for these purposes.
Presenter: Reesa Evans, Lake Specialist, Adams County

History in the Mucking

Wednesday, 8:25-8:50 am

Wisconsin's landscape has changed dramatically during the last 150 years with the arrival of European settlers. This talk will discuss how chemical and biological evidence deposited in lake sediments (muck) are being used to document the impact of these alterations on the landscape and have impacted lakes across Wisconsin.
Presenter: Paul Garrison, WDNR
Presentation:  History in the Mucking

Scientific Lake Research

Zebra mussel (Dreissena polymorpha) Habitat Preference and Population Dynamics in Northeast Wisconsin and Upper Michigan Lakes

Wednesday, 8:00-8:25 am

With limited zebra mussel (Dreissena polymorpha (Pallas)) management options, there is a need to contain the spread through early detection monitoring. Models based on water calcium concentrations currently assist managers by identifying which lakes to focus pre-invasion monitoring. Knowledge of habitat preference will identify locations within lakes that have high invasion potential. This presentation includes the findings of a study that was done to determine zebra mussel habitat preferences and population dynamics in northern Wisconsin and upper Michigan lakes.
Presenter: Maureen Ferry, Graduate Student, WI Cooperative Fishery Research Unit University of Wisconsin – Stevens Point

Efficacy of Zequanox (Pseudomonas fluorescens) for Controlling Dreissenid Mussels in Natural Waters

Wednesday, 8:25-8:50 am

This presentation includes information on the efficacy of Zequanox, a commercial formulation containing dead cells of a strain of Pseudomonas fluorescens bacterium, that was evaluated for use to control dreissenid mussels (D. polymorpha or D. bugensis) in limited field applications.
Presenter: Jon Motquin, Shawano County AIS Coordinator, presenting for Jim Louma, Fisheries Biologist, USGS Upper Midwest Environmental Sciences Center, La Crosse, WI
