O61 field & runways

Cameron Park, Cameron Park, California. Field elevation 1287 ft. Non-towered (NON-ATCT). Magnetic variation 16.0°E on record, 12.8°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 0.091°/year west — about 1° every 11 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	Notes
13	143.9°	131.2°	matches rule gives runway 14 in ~42 yr	4,051 ft	ASPH	left
31	323.9°	311.2°	matches rule gives runway 32 in ~42 yr	4,051 ft	ASPH	left
