The Upper Delaware River region is riddled with water bodies, ranging from rivers to lakes, ponds, streams and wetlands. Those who spend time near such waters are likely to encounter the northern water snake, a large colorful snake that ranges in size from 24 to 50 inches at maturity.
This non-venomous snake is sometimes mistaken for the northern copperhead, a venomous species that prefers drier habitats featuring rocky terrains. Generally speaking, venomous snakes in our region have flattened triangular-shaped heads. But head shape can be misleading.
