Binghamton University is located within the Fuller Hollow Creek Watershed, 

which contains a surface layer of glacial till and shale bedrock underlying the till.

 

In the 1950s & 1960s, the Fuller Hollow creek was straightened during construction of the subdivisions next to campus and the creek. A large section of the creek was moved westward, eliminating an eastern bend. Some small meanders of the creek across from the Binghamton University eastern playing fields were also straightened between the 1930s & mid-1960s.

 

The straightening has caused runoff velocities within the channel to increase, which has increased erosion rates in the stream channel and banks. The glacial till is readily eroded and contributes bed load (rock sized material) and sediment (finer sized material) to Fuller Hollow Creek during storm events.

​

Large floods (2006 & 2011) have caused major increases in erosion. Meter-diameter boulders have been moved large distances downstream. The eroded bed load and sediment are deposited at the mouth of Fuller Hollow Creek in the form of a delta      within the Susquehanna River
