I live in Tucson, and work in Santa Cruz county. The AzFG page had said Bog Hole was good for duck, but a FS guy told me it was destroyed. I've been looking for areas, too. I've checked out ponds this year around the Santa Ritas and Arivaca, but found mostly moor hens. One area that may attract ducks later in the year is around Arivaca lake. I've driven by Bear Grass tank - the largest tank in the vicinity -- and seen only moor hens. I plan to check out Wilcox Playa after crane season. If you find some likely spots, let me know and I'll keep you posted on anything I find.
