Flow Regulation and Obstruction
Habitats Affected: Water column
Common Sources: Dams, water withdrawals, road fill, and culverts
- 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.
