Don't know too much about hunting the Belfair or Quilcene area, but if you're willing to drive a half hour more, Skokomish Flats can be decent at times. Haven't hunted there for a few years, but used to do okay. Kind of hit or miss. Pretty good access too at either Potlatch or Union.

The fields around Hunter Farms (pheasant release site there as well) often flood and pull in quite a few birds on nasty days.

Hope this helps some.
