No plans for chemical treatment of Cazenovia Lake in 2013

Efforts to protect and improve the health of the lake will move ahead in 2013. The town board is focusing on source controls, and is working with the Madison County Soil and Water Conservation District and landowners to install sedimentation basins that will reduce sediment inflow. The town highway department is investigating alternatives to sanding critical roadways and working with the town engineer to improve storm water management practices.

Protecting and restoring Cazenovia Lake for the benefit of all requires a long-term commitment and the application of many tools. Chemical treatment will continue to be one component of an integrated approach to lake management.

However, the Cazenovia Town Board has decided to delay the fourth round of chemical treatment of Cazenovia Lake. The Lake was treated with triclopyr (trade name Renovate OTF®) in 2009, 2010 and 2012 as part of the ongoing battle to bring the invasive species Eurasian water milfoil under control. This plant grows quickly in the late spring and forms a canopy at the water surface, interfering with recreational uses and diminishing the lake’s attractiveness. The chemical treatment, while costly, is quite effective and the overall milfoil abundance in Cazenovia Lake has been greatly reduced.

Experts from Cornell University and the NYS Department of Environmental Conservation attended a Cazenovia Lake Watershed Council meeting in November to review progress and discuss next steps. The November summit ended without consensus on a clear path forward for 2013.

The lake association, town and village representatives have been conferring with our consultants from Allied Biological and agreed to request DEC for permits to implement a “spot-treatment” program in 2013. The intent was to apply chemicals to limited areas where milfoil has rebounded and may again threaten recreational uses. However, after thoughtfully evaluating the expenses of a spot treatment and the challenges in getting necessary permits on a shortened time table, it was decided a treatment for 2013 would not be feasible or productive. So, with apologies to all, representatives of the town board advised the lake association board and village representatives on Feb. 18 that chemical treatment would not be part of the 2013 lake program.
