The Clean Boats, Clean Waters (CBCW) program, coordinated by Wisconsin DNR, works to reduce the spread of aquatic invasive species (AIS) through education and prevention.

You may see CBCW watercraft inspectors and volunteers at our boat landings conducting boat and trailer inspections, sharing educational materials, and helping boaters learn steps to protect our lakes. By cleaning, draining, and inspecting watercraft, we all play a role in preventing the spread of invasive species.

Want to get involved?  A few hours can make a lasting difference. Help us protect our lakes by volunteering with the TCFLA Clean Boats, Clean Waters program. To join this effort, contact us.

Water quality in the Tiger Cat Flowage is monitored through two Wisconsin DNR programs: a cost-share two-year monitoring grant awarded to the TCFLA and the fully funded WDNR program Citizen Lake Monitoring Network (CLMN). TCFLA Water Quality Whisperers, a dedicated team of volunteers, help carry out this important work.

Under the CLMN program, monitoring is conducted on: 

• Upper Twin 
• Placid

WDNR Surface Water Grant (2 yr monitoring – 2025 & 2026)

• Tiger Cat
• McClaine
• Burns

TCFLA Water Quality Whispers monitor key indicators of lake health:

• Water Clarity (Secchi Depth): Measured using a black-and-white Secchi disk to determine how deep sunlight can penetrate the water. Water clarity can be influenced by algae, sediment, and organic matter.

• Chlorophyll-a: An indicator of algae levels within the lake. Elevated concentrations may signal increased nutrient loading and algal growth.
• Total Phosphorus: A key nutrient that can contribute to excessive algae and aquatic plant growth when concentrations become too high.
• Temperature & Dissolved Oxygen Profiles: These measurements help evaluate fish habitat, lake stratification, and the overall health of the aquatic ecosystem.

Together, these efforts provide valuable long-term water quality data that supports informed lake management decisions for today and the future.

Each season, anglers compete in the long-standing TCFLA Pike Improvement Project on the Tiger Cat Flowage.

In partnership with the Wisconsin DNR, the program encourages harvest of 3,000 Northern Pike from Tiger Cat Flowage—particularly those under 24 inches—to help improve balance and support healthy Walley and Musky populations.

The summer-long competition offers cash prizes for harvest of Northern Pike while providing valuable data for long-term fisheries management while also providing valuable fisheries data used to guide long-term management decisions.

For contest details refer to the 2026 Pike Improvement Competition Details.

Through a cost-share grant awarded by the Wisconsin DNR, TCFLA volunteers built and installed informational kiosks at three boat launches on the Tiger Cat Flowage to support lake education, stewardship, and public awareness.

The kiosks provide important information for lake users including boating regulations, bag limits, aquatic invasive species and wildlife alerts, and boating safety guidance.

By placing educational resources directly at lake access points, this project encourages responsible recreation and supports the long-term protection of the Tiger Cat Flowage.

TCFLA gratefully recognizes the private landowners who generously allowed kiosk placement on their properties and continue to support stewardship of our lakes and natural resources.
