About Stream diversion & reduced ecological flow
A recurring Kauaʻi conservation pressure: Stream diversion & reduced ecological flow.
Names and classification
- Record type
- threat
Kauaʻi occurrence and status
- Recorded state
- Active / stream-specific
Threats and conservation
- Pressure source
- Surface-water diversions and water withdrawals
- Exposure pathway
- Reduced discharge, altered seasonal flow and reduced connectivity to lower reaches/estuaries
- Consequences
- Habitat contraction, temperature/quality change, passage loss and altered estuarine salinity
- Affected requirements
- Aquatic habitat, amphidromous passage, water quality and estuarine freshwater input
- Susceptibility
- Native stream fauna, riparian systems, estuaries and cultural/agricultural water uses
- Reversibility
- Potentially reversible through flow restoration/allocation if physical habitat remains
- Early warning indicators
- Discharge; dry reaches; temperature; passage continuity; estuary salinity; diversion rate
Conservation interventions
- Implementation limits
- Magnitude, exposure and trend are not assumed uniform across Kauaʻi; local evidence governs.
