If you plan on taking a trip over to Congers Lake, be careful not to step on its latest resident! Clarkstown Supervisor George Hoehmann says photos of a large snake have been making the rounds online. The New York State Department of Environmental Conservation identified it as a large, native black rat snake. They average between three and five feet in length, though they can be as long as eight feet. In a post on Facebook, Hoehmann said not to fret, the snake only feeds on small rodents, it’s not venomous, and poses no harm to people. If you do encounter it, just give it some space.
