Facilities staff pilot low‑cost zebra‑mussel cleaning prototype for boat landings
Summary
Facilities staff described a low‑cost misting prototype using a diluted bleach solution to remove zebra mussels at Tainer Lake landings; the unit is expected to cost under $500 in parts and could be piloted and scaled if a state grant is pursued.
Facilities staff told the committee they have developed a simple misting prototype to remove zebra mussels from boats at public landings and will pilot the unit at Tainer Lake.
The proposed approach uses a mist sprayer with a solution containing about two tablespoons of bleach per gallon; staff said the device would be built on a skid so it could be moved between landings and would be designed to avoid any runoff into the lake. Staff estimated parts would total under $500 for a prototype; if the pilot succeeds the Tainer Lake rehabilitation district plans to seek state grant funding to produce additional units.
Why it matters: Zebra mussels are an invasive species that can cause economic and recreational impacts; a low‑cost, maintainable cleaning station at landings could reduce spread without requiring expensive commercial equipment.
Representative quote: "It should work out less than $500 in parts," staff said when describing the skid‑mounted misting unit.
Next steps: Build and pilot a prototype at Tainer Lake landings, evaluate effectiveness and maintenance needs, and pursue grant funding for broader deployment if successful.
