 As a tributary of the Passaic River, the Peckman River has been the subject of frequently flooding, particularly from the mid-2000s.The United States Army Corps of Engineers attributes this flooding to an increase in storms and heavy rainfall, which exceed the drainage capacity of the surrounding area.The USACE notes that recent floods have degraded the ecology of Passaic River Basin, largely as a result of erosion, and consistent with the long-term impact seen in watersheds which are heavily urbanized.
