Threats to Habitat

Habitats Affected: Water column

Common Sources: Dams, water withdrawals, road fill, and culverts

Impacts:

Dams, road fill, and pipe culverts can obstruct passage of anadromous fish to historical upstream spawning grounds.

Surface and ground water withdrawals can significantly alter currents, temperature, and oxygen levels to conditions that deter spawning and egg development of anadromous fish.
