OCWA conducts an annual watershed inspection and monitoring program to assist with maintaining the water quality of Otisco Lake, as mandated by the New York State Public Health Commissioner.  Every year, OCWA interns go door to door in the watershed to ask each resident a series of questions about their property, water, sewage disposal systems, and other environmental practices.  For properties along the lake, we conduct dye testing of the septic systems.  

We have implemented an online form that residents can complete in addition to our door-to-door interviews.  The form can be accessed at the link below.  We will also be making phone calls to residents for whom we have phone numbers. 

Our summer inspectors will visit each property in the watershed to verify information and check for obvious issues with septic systems.   Our inspectors will be wearing OCWA logo’d attire and driving white vehicles labeled with OCWA logos. 

Thank you for your assistance in continuing our practices of protecting the lake water quality.
