| Topic | Habitat: Embeddedness in Upper Sonoma Creek 1996 |
| Caption: The Chart shows embeddedness, or the degree to which spawning gravels are buried, as determined by habitat surveys of Upper Sonoma Creek in 1996. Data were summarized by reach. Embeddedness of 25% or less is considered suitable for salmonid spawning (CDFG, 1998). Such favorable conditions were only found in the lower reaches. These visual estimates involve some subjectivity and are not as rigorous as other methods of assessing spawning and incubation habitat conditions. Surveys followed CDFG methods and data provided in Southern Sonoma County RCD report. See Info Links for more information. | |
