Lake and river questions need property-level answers
Millville's municipal history describes Union Lake's development through dams on the Maurice River, and the city identifies both waterways among its natural features. We treat that setting as a reason to ask about outside water levels, not as evidence that every nearby home floods.
Note whether a wet basement coincides with water collecting across the yard or occurs without visible surface flooding. A foundation inspection can address seepage, while floodplain questions need the appropriate property records. We make that distinction before discussing a pump, because an interior system cannot serve as a river flood barrier.
