8D3 field & runways

Sisseton Muni, Sisseton, South Dakota. Field elevation 1162 ft. Non-towered (NON-ATCT). Magnetic variation 3.0°E on record, 2.7°E 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 0.055°/year west — about 1° every 18 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.
Runway	True	Magnetic	Number	Length	Surface	Pattern
16	167.5°	164.8°	matches rule gives runway 17 in ~4 yr	3,400 ft	ASPH
22	224.4°	221.8°	matches rule gives runway 23 in ~59 yr	1,914 ft	TURF	left
34	347.5°	344.8°	matches rule gives runway 35 in ~4 yr	3,400 ft	ASPH	left
4	44.5°	41.8°	matches rule gives runway 5 in ~59 yr	1,914 ft	TURF	left
