What this tracks
This dataset maps Kansas’ sub-watershed boundaries using 10-digit Hydrologic Unit Codes (HUC-10), which divide the state into smaller drainage areas.
Why it matters to you
If you own farmland in Kansas, this data shows exactly which watershed your property sits in — crucial for understanding flood risks, irrigation rights, or runoff regulations. Developers can check if a parcel drains into protected waterways before planning construction. Rural residents can identify which creek or river their local water quality issues might originate from.
How to read this data
HUC_10 — A unique 10-digit code for each watershed (e.g., 1024000509).
HU_10_NAME — The watershed’s common name (e.g., “Little Tarkio Creek-Missouri River”).
SQ_MILES — The area size in square miles (e.g., 21.99), helping compare watershed scales.
