Here is a map of the Watershed in Ocean County https://barnegatbaypartnership.org/learn/watershed-map/

I was actually hoping to see how the water distributes on the map... but it only shows the area. Sawmill creek is not there, and it feeds into the Manasquan River which leads to the ocean in Brick and Point Pleasant. That's Ocean County. I'm guessing the map needs updates. Thanks for sharing anyway.
