Why think about the future?
Lake Wingra is a community resource
FOLW is developing goals for the watershed in collaboration with the community
Future changes in the greater Madison area and beyond will impact our ability to meet the goals for Lake Wingra

Scenario analysis
• One approach to thinking about the future
• Scenarios are not predictions!
• Scenarios are plausible stories that expand our understanding of what the future might bring

2015: “Success breeds success”• New individuals &
organizations join Friends of Lake Wingra
• “Friends” generate & leverage more resources
• Pressure local government to improve water quality
![Page 46: Future of Lake Wingra Meeting University of Wisconsin May 9, 2007.](https://reader034.fdocuments.in/reader034/viewer/2022042717/56649f455503460f94c67191/html5/thumbnails/46.jpg)
2015-2025: “Gridlock”• Community change: Older, more culturally &
geographically diverse
• Violent conflict between anglers and fisher people
• C-CLEAR positively broadens access, outreach & education

2015-2025: “Gridlock” (cont.)
• Dane county population & power grows; gridlock over environmental policy ensues
• Geographically broader coalition organizes across watershed; Yahara-CLEAR
• Less effort focused locally on original goals

2025-2035: “Sustainable Organizing”
• Fracture: members leave & resume working locally
• Water quality steadily improved, but slower than members hoped
• Uncertainty over the coalition’s future

What can you do now to make Lake Wingra a better resource for you and your neighbors?
What do you see as priorities for managing Lake Wingra?
