What this tracks
This dataset maps Kansas’ watershed boundaries using 8-digit Hydrologic Unit Codes (HUCs), which divide land areas based on water flow patterns.
Why it matters to you
If you’re buying property near a creek or planning a farm irrigation system, this data shows which watershed your land sits in—critical for understanding flood risks and water rights. Developers in Kansas City can check HUC boundaries to anticipate stormwater runoff regulations. Homeowners near the Missouri-Nishnabotna basin can identify upstream pollution sources affecting their local water quality.
How to read this data
HUC_8 — An 8-digit code like “10240005” representing a specific sub-watershed, often used in permitting (e.g., well drilling applications).
HU_8_STATE — Lists states the watershed crosses (e.g., “IA KS MO NE”), important for interstate water agreements.
SQ_MILES — Shows the watershed’s size (e.g., “1701”), helping gauge potential flood impact areas.
