Winter pool
Winter pool is the lower seasonal target many USACE reservoirs hold after fall drawdown—freeing flood storage and reducing ice/wind fetch stress on docks. It is published beside full pool in rule curves with the same datum discipline.

Why it matters
Boat ramps that were deep at summer full may be marginal after drawdown. Bass relate to channel swings and remaining timber tops that were underwater in July. Marinas adjust slip cables to a new normal.
