ok, I lived in vegas for two years and hunted there only 1 season. there are a few options.
1. Overton WMA. Reservation only--basically where everyone from vegas goes. because it is about 45 min from Nellis. They have set up blinds that you must use. It just never seemed like real hunting so I never went there.
2. Ash Meadows NWR. About an hour and a half north west of Vegas near Pahrump. It is a new fuge; I never went there.
3. Pahranagat NWR about an hour and 10 min from Nellis. Two years ago it was close to being dry. Last year the lake had a good amount of water and no plant growth. I am sure (with this last winter) there is much more growth and Ducks. they have bunch of local ducks and you obviously get northern birds depending on when it freezes up north.
you can do well here, you just have to explore and do your scouting. There a bunch of locals that always hunt in their spot and skybust the place to hell (lower lake only).
PM me with more questions. good luck
