Funding of fisheries management
About
• Formed in 2009
• > 40K lakes
• 3 key components
(Science, Conservation,
Outreach)
• $2.16M in projects
From 2013-2015:
• 8.5K lake surface acres protected by easements and erosion mitigation
• 7K lake acres reconnected
• Outreach to 61K stakeholders

How can we prioritize lakes for rehabilitation work?
Science team project 1:Lake fisheries + habitat assessment
Predicted fish species presence for
~40,000 lakes (Temp is the key driver)

Future goals
• Hindcast (40 y) and
forecast (to 2100) daily
lake simulation models
(using super computing)
for all Cisco lakes in
Wisconsin
• Expand across all lakes
in the MGLP partnership
• Work with agencies and
MGLP to prioritize lake
habitat rehabilitation
• Focus on land
management!
Extirpation
P reduction
Forest Management
Healthy lands = healthy fish(But…this is not traditional thinking!)
