What this tracks
This dataset maps the boundaries of Nebraska’s watersheds using 8-digit Hydrologic Unit Codes (HUC8), which divide land areas based on water flow patterns.
Why it matters to you
Knowing your HUC8 boundary helps you understand local water risks and regulations. If you’re a farmer in Nebraska, this tells you which watershed your land falls into—critical for irrigation planning or applying for conservation programs. Homeowners can identify flood risks by seeing if their property sits near a watershed boundary where water converges during heavy rains.
How to read this data
HUC8 — A unique code for each watershed (e.g., “10250001” for the Arikaree region).
NAME — The watershed’s common name (e.g., “Arikaree” covers parts of CO, KS, and NE).
AREAACRES — The watershed’s size in acres (e.g., 1,182,065 acres for Arikaree).
