- •
River flows to an inverted estuary were diminished during prolonged drought.
- •
Extreme hypersalinity led to >50% reduction in the range of smallmouth hardyhead.
- •
Salinity exceeded the osmoregulatory limit of the fish in much of its range.
- •
Salinity returned to pre-drought levels following the return of river flows.
- •
The smallmouth hardyhead population recovered to its former range after 2-years.
