Kirkwood measures at upper and lower locations, usually quotes only the upper. I average the 2 quotes, because that meshes with historical data from Carson Pass elevation 8,526 feet. So that's a mid mountain average of 473 inches. Sugar Bowl's 467 is near its base, so TruckeeLocal is probably correct that it gets the most snow. Sugar Bowl's lower elevation and NW leading edge position in the Sierra does mean wetter snow and somewhat increased rain incidence relative to Kirkwood.
I do have some concern about changes in Mammoth's reporting methodology. If you could enlighten me as to the specifics I'd appreciate it. Reporting from the Main Lodge area seems fair, as it would be less than the top but more than the Canyon Lodge side of the mountain. Current average since 1969 of 363 inches might include some understatements in a few of those old years, but unlikely to move the average anything close to 100 inches. FYI I adjusted 1969 up to 505 inches myself already by looking up L.A. Times microfiches.
From a practical skiing perspective Mammoth has huge advantages that could make people think it gets more snow. Most obvious is the blow-in snow on the upper mountain. It is also the only area that combines high water content Pacific snow with Rockies-like elevation to create massive and long lasting snow depths. Nonetheless, in average seasons snow depths are higher at Kirkwood, Sugar Bowl and the upper elevations of Squaw/Alpine until sometime in March when Mammoth's snow preservation advantages come to the fore. Another Mammoth advantage is topography. Many of the lower slopes are fairly gentle and can be skied on a 2-3 foot base, while the steep upper slopes get more snow plus that blow-in.
In most seasons there are storms that hit Tahoe harder, or don't even get as far south as Mammoth. In November the snow has rarely been around long enough for Mammoth's snow preservation advantages to come into play. You're often looking at the result of just one storm, and in that situation the Sierra Crest west of Tahoe is slightly more likely to have the most snow. But the variability is so high you really have to look at the specifics of that first storm and choose accordingly.
