Hutchinson County, SD Roof Snow Load - 28 psf
What ASCE 7 says about snow load in Hutchinson County
That's Hutchinson County's design roof snow load per ASCE 7-22, for a typical heated single-family home - the number a permit reviewer starts from.
Converted to something you can actually eyeball on a roof: about 61.6 in. of fresh powder, 22.4 in. once it settles and packs down, or just 5.6 in. if it's turned to ice. This is a meaningful design load - most modern-code homes handle it fine, though an addition, a carport or a flat-roofed section can be a weak spot.

Read this before you rely on it
