Unknown — not enough evidence to call a runway

KCWI field & runways

Clinton Muni, Clinton, Iowa. Field elevation 708 ft. Class E airspace. Non-towered (NON-ATCT). Magnetic variation 0.0°W on record, 2.2°W today.

The FAA's variation of record is the number this field was surveyed against; the second is where north points now, from WMM2025. It is moving 0.042°/year west — about 1° every 24 years — which is why runway numbers eventually stop matching their pavement.

Runway data from the FAA NASR 01 Oct 2026 cycle. Where NASR locates both thresholds, the true heading is the bearing between them rather than NASR's whole-degree alignment. Magnetic is that heading against *today's* declination from WMM2025, not the field's variation of record — so it can differ from the chart by the gap between the two shown above. The number painted on the runway is the one ATC uses.
