Freshwater fishes are vulnerable to sedimentation, changes in water
temperatures, excess pollutants, extreme water level changes, and barriers
to movement, such as dams or poorly designed stream crossings. For more
information about these species, read the fact sheets that can be accessed
through the MESA
List.
