Description

1

1

Streams with anadromous (fish ascending from oceans to breed in fresh water) or adfluvial (fish ascending from fresh water lakes to breed in streams) lake and stream habitat. Also included is the habitat upstream from migration barriers known to be reasonable enhancement opportunities for anadromous fish and habitat with high value resident sport fish populations.

2

2

Streams with resident fish populations and generally steep (often 6-15 percent) gradient (can also include streams from 0-5 percent gradient where no anadromous fish occur). These populations have limited sport fishery values. These streams generally occur upstream of migration barriers or are steep gradient streams with other habitat feature that preclude anadromous fish use.

3

3

Streams with no fish populations but which have potential water quality influence on the downstream aquatic habitat.

4

4

Water quality stream without water quality influence on the downstream aquatic habitat.
