| Topic | Habitat: Percent Types by Length of NF Gualala Reaches 2001 |
The image above shows California Department of Fish and Game Habitat Typing results displayed as habitat frequency by length for the North Fork Gualala Basin. The predominance of pools in the mainstem North Fork and lower Little North Fork would suggest suitable habitat for salmonids. Lacks of pools in Doty Creek (upper right tributaries in Doty Creek Calwater) and in the upper Little North Fork suggest aggradation. Similarly, the extensive dry reaches in Robinson, McGann and Dry Creeks are also a clear indication of major aggradation and that salmonid rearing habitat is severely impaired.
