Canadian County, OK Roof Snow Load - 10 psf
Canadian County, OK roof snow load, translated
A typical heated home in Canadian County is designed to carry 10 pounds per square foot of snow on its roof, per ASCE 7-22. 7 psf is what the ground-load formula alone gives; Canadian County's 10 psf low-slope minimum (§7.3.4) beats it, so that figure is the one that governs on flat and low-pitch roofs.
On a roof that means 22 in. of fresh snow, 8 in. once it packs down, or 2 in. of solid ice - three very different piles for the same load. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Where Canadian County ranks
#22 of 77 Oklahoma counties by design load, top 61% of 2,758 nationally - that's Canadian County's spot. Oklahoma counties average 11 psf; Canadian County runs 1 psf lower than that.
FIPS 40017, population 181,760, centered near 35.5434°N 97.9799°W. ASCE 7's underlying ground snow load here is 10 psf before the code's exposure and importance factors bring it to the 10 psf design figure above.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
A building permit needs the number at your exact address, not the county average - the free ASCE 7 Hazard Tool returns that from your coordinates in about a minute and produces a PDF a plan reviewer will accept. See the methodology guide.
