Wheeler County, OR Roof Snow Load - Case Study Area
What "Case Study" means for Wheeler County
ASCE 7's own snow load map has no single figure for Wheeler County: the terrain is complex enough that the code (§7.2) requires an elevation-specific study rather than a county-wide value. That is the map being accurate, not a data gap.
FIPS 41069, population 1,456. 386 US counties get this same case-study treatment; Wheeler County is one of them.

Wheeler County: average annual snowfall
Wheeler County sees about 25.5 in. of snow most winters, per the CONDON, OR US station's 1991-2020 NOAA normal. That station is far enough away (35.6 mi) that local snowfall - especially at a different elevation or near a lake - can run noticeably higher or lower than this figure. See the density guide.

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. Details: the calculation guide.
