Living with the river
Water & habitat
Clean gravel and oxygenated water matter. Sediment, warming and pollution can reduce suitable habitat; one streamflow number cannot describe all of those conditions.
Seasonal life
Males build shallow gravel nests in spring and guard eggs and young. Nesting dates vary with local water temperature.
