Madison’s Natural Treasures Under Threat
Madison, Wisconsin, is defined by its stunning chain of Yahara Lakes – Mendota, Monona, Waubesa, and Kegonsa. These interconnected waters serve as more than picturesque backdrops; they’re vital recreational hubs, ecological treasures, and the cornerstone of our community’s identity.
The Stakes Are High:
- $220 million annual economic impact to the region
- Critical habitat for diverse aquatic ecosystems
- Prime recreational destination for boating, fishing, and swimming
- Defining feature of Madison’s quality of life
Yet for decades, these lakes have battled a persistent enemy: excessive phosphorus pollution that creates unsightly algae blooms and threatens water quality.
The Phosphorus Problem
What’s Happening in Our Lakes
Excess phosphorus acts as a super-fertilizer for algae, creating:
- Vibrant green “pea soup” water conditions
- Diminished recreational opportunities
- Reduced property values along shorelines
- Potential health risks from toxic algae blooms
- Ecological damage to fish and wildlife populations
Primary Sources of Pollution
Phosphorus enters our lakes through multiple pathways:
- Agricultural runoff from fertilizers and manure
- Urban stormwater carrying nutrients from streets and lawns
- Legacy sediment accumulated over decades in waterways
- Erosion from construction and development
Spotlight: Pheasant Branch Creek Challenge
The Pheasant Branch watershed presents unique challenges as a major contributor to Lake Mendota’s phosphorus load:
- Historical impacts from 1850s creek channelization
- Mixed land use combining rural agriculture and urban development
- Legacy phosphorus stored in streambeds and wetlands
- Increased runoff from decades of development pressure
Comprehensive Solutions in Action
Agricultural Best Management Practices
No-Till Farming and Cover Cropping
- Farmers through Yahara Pride Farms adopt soil-protecting practices
- Winter cover crops prevent erosion and nutrient loss
- No-tillage methods keep protective vegetation in place year-round
Responsible Nutrient Management
- Optimized fertilizer and manure application timing
- Low-disturbance manure injection techniques
- Precision agriculture to match nutrients with crop needs
Natural Buffers and Filters
- Vegetated buffer strips along waterways
- Natural filtration of runoff before reaching creeks
- Wildlife habitat creation alongside water protection
Innovative Manure Processing
- Dane County’s “Cow Power” digesters convert waste to energy
- Advanced technology removes phosphorus from manure
- High-quality compost production reduces field applications
Urban Stormwater Management
Community Action Programs
- Leaf Free Streets Campaign prevents autumn phosphorus pollution
- Resident education on phosphorus-free lawn care products
- Car washing guidelines to protect storm drains
Infrastructure Solutions
- Stormwater retention structures in developing areas
- Increased infiltration through green infrastructure
- Silt curtains at construction sites preventing sediment transport
Legacy Sediment Removal
“Suck the Muck” Projects Dane County’s ambitious sediment removal initiatives target:
- Phosphorus-laden muck in Dorn Creek and Token Creek
- Internal pollution sources that fuel ongoing algae blooms
- Long-term lake health through strategic dredging
Success Stories and Proven Results
Yahara WINS Partnership
This innovative collaboration brings together:
- Farmers and agricultural producers
- Municipalities and local businesses
- Madison Metropolitan Sewerage District
- Dane County environmental agencies
Impressive Results:
- 54,541 pounds of phosphorus prevented from entering waterways in 2023
- Seven consecutive years exceeding reduction goals
- Consistent higher-than-expected performance since 2017
Acker Farm Restoration Success
The 159-acre Acker property restoration represents:
- $10 million investment in conservation
- Largest conservation land acquisition in Dane County history
- Conversion from cropland to protective perennial vegetation
Measurable Impact:
- 5 million gallons of water runoff prevented annually
- 550+ pounds of phosphorus reduction per year
- 275,000 pounds of algae growth prevented annually
- 95% reduction in pollutant loading documented post-restoration
Pheasant Branch Creek Targeted Solutions
Wetland Restoration
