Historically there was a tidal marsh at its mouth, but some of this reach has been degraded by fill, especially in the construction of West Point Drive. This westernmost reach of the creek has been especially ecologically productive, and part of the reason for Fitzgerald Marine Reserve's designation on August 5, 1969, as a state reserve and was named after James V. Fitzgerald.
