After meeting a small tributary on its right bank, Jackson Creek resumes a southwestward course and crosses under New York State Route 55, locally Freedom Plains Road.
Now in a more developed area, it converges with another creek and flows under County Route 21 (Noxon Road).
[4] The creek's New York State Department of Environmental Conservation classification varies from class C(T) to C(TS).
The creek suffers numerous impairments, including flooding, erosion, sedimentation, man-made alteration, litter, and invasive plants.
A 2007 study found 16 drainage pipes along the creek, as well as coverts and bridges that restrict its flow and result in localized flooding.
