Streams, rivers and small to large ponds and lakes.
Threats to Survival
Habitat destruction and degradation, eutrophication, sedimentation and invasive species are common in all habitats. River populations are threatened by alteration of natural flow regimes, encroachment of river corridors by development, habitat fragmentation and historical land use. Lake populations are threatened by intense development, modification and recreational use of sensitive shoreline habitats, and dams and other stream barriers.
Actions Recommended to Ensure Survival
Mitigate pollution, limit habitat degradation, maintain naturally variable river flow and limit water withdrawals, maintain adequate vegetated riparian buffer along rivers and lakes and protect or acquire land at high priority sites.
