Humpback chub
Little is known about conditions needed for overwintering humpback chub.
However, it is presumed that these fish occupy the same habitats in the
winter as in autumn.
Winter recommendations
Stable winter flows near the 50% exceedence value are recommended. Flows
lower than 75% exceedence (fable 2) caused loss of habitat and may result in
winterkill of smaller fish in pools.
