The upper watershed location and limited land-use within Morristown National Historical Park generally serve to protect the integrity and quality of the water resources within the Jockey Hollow and New Jersey Brigade units.
While human-related activities outside the park have severely impacted water resources lower in the Great Swamp/ Passaic River watershed. Surface and ground water resources within Morristown National Historical Park generally remain in good condition.
Indian Grave Brook and a segment of the Passaic River from its source are designated as FW-2 trout maintenance waters.
Primrose Brook is also classified as "Category One (anti-degradation) Waters" by New Jersey Surface Water Quality Standards.
