Building on 2019: Year of Clean Drinking Water and Water Quality - Thursday, 8:00-8:50 am

Legislative Update          

2019 was an eventful year for water policy in Wisconsin. The Governor declared it the Year of Clean Drinking Water during his inaugural State of the State address, and Assembly Speaker Robin Vos launched his Speaker’sTask Force on Water Quality, which published its final report in January 2020. A number of bills and initiatives resulted from this work; we’ll recap where things stand in the spring of 2020 and discuss additional legal and policy updates impacting surface waters. 
 
Presenter: Mike Engleson, Executive Director, Wisconsin Lakes

Ecology: Life In and Around Our Waters - Thursday, 8:00-8:50 am

Tribal Resource Panel          

Tribal water resource professionals will discuss different aspects of their work in tribal water resource programs & working for a Tribe. The topics will range from tribal water quality standards, permits, jurisdiction, consultation, what the Tribes can do for non-tribal members, and more. There will be chances for participants to ask questions. 
 
Presenters: 
Celeste Hockings, Water Resource Program Manager / Aquatic Ecologist - Lac du Flambeau Band of Lake Superior Indians
James "Jim" Snitgen, Water Resources Supervisor - Oneida Nation Environmental, Health and Safety Division 

Lake and River Science - Thursday, 8:00-8:50 am

A Changing Lake: Addressing Low Dissolved Oxygen and High Phosphorus in Wisconsin’s Deepest Natural Inland Lake, Green Lake          

As the deepest natural inland lake in Wisconsin, Green Lake is a unique lake with long-term water quality degradation. In 2014, Green Lake was listed as impaired for its progressively worsening mid-depth dead zone--with dissolved oxygen concentrations annually falling below 5 mg/L--in addition to low dissolved oxygen at its bottom waters. Phosphorus concentrations are also increasing above the lake’s water quality criteria of 15 ug/L. In a public-private partnership, the lake association, USGS, and Michigan Technological University are carrying out a multi-year, WDNR-funded research study based on rigorous data and several lake models. The goals of this study are: 1) better understand the lake’s water quality changes, 2) determine the causes of degradation (for dissolved oxygen and phosphorus), 3) identify and quantify management efforts to improve water quality, and 3) create a more resilient lake able to withstand growing pressures from land use and climate change.

Addressing Climate Change Impacts on Lakes and Rivers - Thursday, 8:00-8:50 am

*Two 25 minute presentations

Wisconsin's Changing Climate and Forecasting Aquatic Invasive Species Spread          

In coming decades, Wisconsin's climate is expect to shift with changes in precipitation and temperature. Areas of Wisconsin are expected to resemble the climatic conditions of other US states. As climate shifts ecosystems, there will be an increased strain as community compositions, dynamics, and species-specific responses are altered by novel climates. It is possible, however, to predict how species may respond to future climates using modelling tools including the WICCI Climate Analogue Matching tool and USFWS's Risk Assessment Mapping Program. 
 
Presenter: Jason Granberg, Conservation Biologist, Wisconsin Department of Natural Resources

Coldwater Trout Streams in Wisconsin: Loss, Recovery, and Building Resilience to Adapt to Climate Change     

Water temperature is a key factor in determining where coldwater fish species such as Brook Trout (Salvelinus fontinalis) and Brown Trout (Salmo trutta) live in streams. Our past experiences in losing and restoring coldwater stream habitat can help inform how to address potential losses attributable to climate change. In this presentation I will give a brief overview of the history of coldwater stream loss and recovery in Wisconsin; present empirical data to show how temperatures have been warming in some streams consistent with ongoing changes in climatic conditions; show how projected changes in climate may further change coldwater stream habitat in Wisconsin; and discuss how stream habitat development projects are being used to repair degraded streams and to build resilience to stream warming by helping to keep our cold water cold. 
 
Presenter: Matt Mitro, Fisheries Research Scientist, Wisconsin Department of Natural Resources

Monitoring to Action: Stories from the Field - Thursday, 8:00-8:50 am

* Two 25 minute presentations

Volunteer Lake Level Monitoring for Management and Research          

Volunteers across Wisconsin are monitoring lake levels with help from WDNR, other governmental agencies, non-profits and consultants. A long-term lake level monitoring record gives context to the extreme high and low lake levels we have seen in recent years.  It also aids lake level management and research. This talk will describe the ins and outs of lake level monitoring and will give examples of what we are learning from this valuable data set. 
 
Presenter: Katie Hein, Lake Monitoring Technical Lead, Wisconsin Department of Natural Resources

How DNR Addresses High Water Levels          

A look into how DNR navigates complex water level issues. Learn about best management practices that homeowners can implement to mitigate some effects of high water level conditions. 
 
Presenter: Andrea Stern, Water Management Engineer, Wisconsin Department of Natural Resources
