What this tracks
This dataset records all dams in Nebraska that meet specific size criteria (25+ feet tall or 50+ acre-feet capacity), including their locations, purposes, hazard ratings, and maintenance status.
Why it matters to you
If you’re buying property downstream from a dam, this data tells you whether the structure is classified as a “Significant” hazard (meaning failure could cause loss of life) or has flood control purposes that might affect your land. Farmers can check NormalStorage values to assess water availability for irrigation. Anglers and outdoor enthusiasts can use Stream and NormalSurfaceArea fields to find potential fishing spots near dams like RUTHER DAM in Cheyenne County.
How to read this data
Hazard — Rates potential danger if the dam fails (sample: “Significant”).
Purpose — Main function like “Flood Control” or “Storm Water Mgmt” (sample: “C - Flood Control, Storm Water Mgmt”).
LastInspectionDate — When officials last checked the dam’s condition (sample: 1679504400000 = March 23, 2023).
Downstream_Town — Nearest community below the dam (sample: “SIDNEY” is 1 mile downstream).
Try it yourself
Search the dataset by your county name to see if any dams upstream from your property have “Flood Control” purposes or “Significant” hazard ratings that could affect your flood insurance needs.
