Colorado deer (whitetail in eastern river drainages, mule deer elsewhere) rely on browse and forb forage more than mast. Limited bur oak and Gambel oak occur in eastern plains and southern foothills; statewide mast surveys are not a focus of state agencies.
Categorical ratings (failure → excellent) per year. Overall is solid; white oak and red oak series are dashed.

No mast survey published; mast is a minor variable in Colorado deer hunting.
Crop quality not yet documented for this year. Check the linked agency source for the most current published survey, and scout productive oaks directly when in the field.
Average for state's limited mast habitat.
Mixed conditions — some areas with productive oaks, others without. Scout for the pockets that produced and hunt the travel routes between bedding and mast. Plots and ag fields still hold deer where mast failed.
Drought-influenced; minimal hunter-relevant change from typical years.

Limited oak habitat; generally moderate production where it occurs.

Without a current mast read, lean on travel-corridor and food-plot setups while you scout for productive oaks in the field.
