Data Used to Assess Water Quality: |
Temperature data were evaluated against the temperature requirements of the beneficial use most sensitive to increases in temperature, salmonids. The most sensitive lifestage occurring during July & August when the MWMTs occur is rearing. 8 of 8 MWMT values calculated from temperature samples collected in Bear Pen Creek exceed the evaluation guideline for the protection of core-rearing. MWMT values ranged from 17.5 to 20.9 degrees C. This LOE replaces the portion of LOE 1678 that contains data for Bear Pen Creek from the 2006 Listing Cycle. In LOE 1678 the raw temperature data was compared to the MWAT evaluation guideline, when in fact MWAT values should have been calculated from the raw data and compared to the MWAT evaluation guideline. For this listing cycle we are utilizing an MWMT evaluation guideline, instead of an MWAT, as it better captures temperature extremes. |

Water Quality Objective/Criterion: |
Water Quality Control Plan, North Coast Region (NCRWQCB 2011): Natural receiving water temperature of intrastate waters shall not be altered unless it can be demonstrated to the satisfaction of the Regional Water Board that such alteration in temperature does not adversely affect beneficial uses. At no time or place shall the temperature of any COLD water be increased more than 5 degrees Fahrenheit (F) above natural receiving water temperature. |
Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) for the North Coast Region |
|
Evaluation Guideline: |
If the natural receiving water temperature has been altered, or if alternation is unknown, the evaluation guideline to determine adverse affect on the most sensitive beneficial use (in this case, salmonids) is as follows. Per "U.S. EPA Region 10 Guidance for Pacific Northwest State and Tribal Temperature Water Quality Standards" (USEPA 2003), the U.S. EPA recommends a criterion for the protection of moderate to high density summertime salmon and trout juvenile rearing (i.e., core juvenile rearing) of a maximum weekly maximum temperature (MWMT) of 16 degrees C. The MWMT is also known as the maximum 7-day average of daily maximums (7DADM). The 16 degrees C MWMT criterion is recommended to (1) safely protect juvenile salmon and trout from lethal temperatures; (2) provide upper optimal conditions for juvenile growth under limited food during the period of summer maximum temperatures and optimal temperatures for other times of the growth season; (3) avoid temperatures where juvenile salmon and trout are at a competitive disadvantage with other fish; (4) protect against temperature induced elevated disease rates; and (5) provide temperatures that studies show juvenile salmon and trout prefer and are found in high densities. |

The MWMT is also known as the maximum 7-day average of daily maximums (7DADM). The 16 degrees C MWMT criterion is recommended to (1) safely protect juvenile salmon and trout from lethal temperatures; (2) provide upper optimal conditions for juvenile growth under limited food during the period of summer maximum temperatures and optimal temperatures for other times of the growth season; (3) avoid temperatures where juvenile salmon and trout are at a competitive disadvantage with other fish; (4) protect against temperature induced elevated disease rates; and (5) provide temperatures that studies show juvenile salmon and trout prefer and are found in high densities. |

In addition, the following temperature objectives apply to surface waters: The natural receiving water temperature of intrastate waters shall not be altered unless it can be demonstrated to the satisfaction of the Regional Water Board that such alteration in temperature does not adversely affect beneficial uses. At no time or place shall the temperature of any COLD water be increased by more than 5°F above natural receiving water temperature.

Evaluation Guideline: |
The guideline used was from Sullivan et al. (2000) Published Temperature Thresholds-Peer Reviewed Literature which includes reviewed sub-lethal and acute temperature thresholds from a wide range of studies, incorporating information from laboratory-based research, field observations, and risk assessment approaches. This report calculated the 7-day Mean (maximum value of the 7-day moving average of the daily mean temperature) upper threshold criterion for coho salmon as 14.8°C and for steelhead trout as 17.0°C. The risk assessment approach used by Sullivan et al. (2000) suggests that the 7-day average upper threshold of a 14.8°C for coho and 17.0°C for steelhead will reduce average growth 10% from optimum. |

The sampling sites were located along the main stem of the South Fork Eel River, Indian Creek, Moody Creek, Anderson Creek, Piercy Creek, Standley Creek, Bear Pen Creek, Wildcat Creek, Hollow Tree Creek, Dutch Charlie Creek and Redwood Creek. A total of 10,476 sampling measurements were taken at 13 sampling locations from 1994 to 2003. In-stream and riparian measurements were taken at all monitoring locations. |
Temporal Representation: |
Data was recorded for 10 years, from 1994 through 2003. Water temperature data were recorded at ninety-minute intervals, generally from June until Mid-October. Stream temperatures were measured continuously with temperature data loggers (Onset Computer Corp. model HOBO-Temp and OST temperature loggers) in Class 1 streams throughout the property from 1994 to 2004. Hobo-temps allowed uninterrupted data collection to occur throughout the critical summer period. |

Temperature data were evaluated against the temperature requirements of the beneficial use most sensitive to increases in temperature, salmonids. The most sensitive lifestage occurring during July & August when the MWMTs occur is rearing. 7 of 7 MWMT values calculated from temperature samples collected in Standley Creek exceed the evaluation guideline for the protection of core-rearing. MWMT values ranged from 17.2 to 19.7 degrees C. This LOE replaces the portion of LOE 1678 that contains data for Standley Creek from the 2006 Listing Cycle. In LOE 1678 the raw temperature data was compared to the MWAT evaluation guideline, when in fact MWAT values should have been calculated from the raw data and compared to the MWAT evaluation guideline. For this listing cycle we are utilizing an MWMT evaluation guideline, instead of an MWAT, as it better captures temperature extremes. |

EVIDENCE OF ALTERATION OF NATURAL RECEIVING WATER TEMPERATURE: Water temperatures in the South Fork HA have been altered and do not reflect natural receiving water temperatures as environmental factors that influence water temperature have been altered by human activities. Anthropogenic factors resulting in altered stream temperatures include the clearing of ripairan canopy for roads and timber production (USEPA 1999). EVIDENCE OF SALMONID PRESENCE & LIFE CYCLE USE: Coho, steelhead and Chinook are present in the South Fork Eel HA (USEPA 1999; Yoshiyama and Moyle 2010). Rearing occurs year round and spawning/ incubation/ emergence occurs from November to April (Busby et al. 1996; CDFG 2004; Myers et al. 1998). Non-core rearing occurs in the mainstem Eel River, while core rearing occurs in tributaries. |

The 16 degrees C MWMT criterion is recommended to (1) safely protect juvenile salmon and trout from lethal temperatures; (2) provide upper optimal conditions for juvenile growth under limited food during the period of summer maximum temperatures and optimal temperatures for other times of the growth season; (3) avoid temperatures where juvenile salmon and trout are at a competitive disadvantage with other fish; (4) protect against temperature induced elevated disease rates; and (5) provide temperatures that studies show juvenile salmon and trout prefer and are found in high densities. |

Temperature data were evaluated against the temperature requirements of the beneficial use most sensitive to increases in temperature, salmonids. The most sensitive lifestage occurring during July when the MWMT occurred is rearing. 1 of 1 MWMT value calculated from temperature samples collected in Hollow Tree Creek exceed the evaluation guideline for the protection of core-rearing. The MWMT value was 24.3 degrees C. This LOE replaces the portion of LOE 1678 that contains data for Hollow Tree Creek from the 2006 Listing Cycle. In LOE 1678 the raw temperature data was compared to the MWAT evaluation guideline, when in fact MWAT values should have been calculated from the raw data and compared to the MWAT evaluation guideline. For this listing cycle we are utilizing an MWMT evaluation guideline, instead of an MWAT, as it better captures temperature extremes. |

Water Quality Objective/Criterion: |
Per the Basin Plan (NCRWQCB 2007): All waters shall be maintained free of toxic substances in concentrations that are toxic to, or that produce detrimental physiological responses in human, plant, animal, or aquatic life. |
Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) - North Coast Region (Region 1) |
|
Evaluation Guideline: |
Per the National Recommended Water Quality Criteria (USEPA 2006): The 1-hour average concentration (acute criterion or CMC) of total ammonia nitrogen (in mg N/L) for freshwater where salmonid fish are present, which is not to be exceeded more than once every three years on average, is calculated using the following equation: CMC=0.275/(1+10^(7.204 - pH)) + 39.0/(1+10^(pH - 7.204)). |

Spatial Representation: |
Samples were collected from the South Fork Eel River Watershed at 4 locations as follows: (1) from the mainstem South Fork near Branscomb (SWAMP Station ID 111EELBRN), (2) from the mainstem South Fork near Benbow (SWAMP Station ID 111EELBEN), (3) from the mainstem South Fork downstream of Bull Creek (SWAMP Station ID 111EELSFK), and (4) from Elder Creek (SWAMP Station ID 111ELDRCR). Samples were collected from well-mixed flows in glides or riffles. |
Temporal Representation: |
At the Branscomb site, samples were collected from 13 site visits from February 2002 to April 2005. At the Benbow site, samples were collected from 4 site visits from February to June 2002. At the site downstream of Bull Creek, samples were collected from 23 site visits from March 2001 to June 2006. At Elder Creek, samples were collected from 19 site visits from February 2002 to June 2006. Most of the site visits corresponded to fall, winter, spring and early summer seasonal conditions. |
Environmental Conditions: |
There are no known environmental conditions (e.g., seasonality, land use practices, fire events, storms, etc.) that are related to these data. |
QAPP Information: |
Quality control was conducted in accordance with the SWAMP Quality Assurance Management Plan (Puckett 2002). |

Water Quality Objective/Criterion: |
Per the Basin Plan (NCRWQCB 2011): All waters shall be maintained free of toxic substances in concentrations that are toxic to, or that produce detrimental physiological responses in human, plant, animal, or aquatic life. Compliance with this objective will be determined by use of indicator organisms, analyses of species diversity, population density, growth anomalies, bioassays of appropriate duration, or other appropriate methods as specified by the Regional Water Board. |
Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) for the North Coast Region |
|
Evaluation Guideline: |
Toxicity is defined as a statistically significant effect in the sample exposure compared to the control using EPA-recommended hypothesis testing. For SWAMP data exceedances are counted with the significant effect code SL. SL is defined as the result being significant compared to the negative control based on a statistical test, less than stated the alpha level, AND less than the evaluation threshold. |

Data Used to Assess Water Quality: |
Temperature data were evaluated against the temperature requirements of the beneficial use most sensitive to increases in temperature, salmonids. The most sensitive lifestage occurring during July when the MWMT occurred is rearing. 1 of 1 MWMT value calculated from temperature samples collected in Hollow Tree Creek exceed the evaluation guideline for the protection of core-rearing. The MWMT value was 24.3 degrees C. This LOE replaces the portion of LOE 1678 that contains data for Hollow Tree Creek from the 2006 Listing Cycle. In LOE 1678 the raw temperature data was compared to the MWAT evaluation guideline, when in fact MWAT values should have been calculated from the raw data and compared to the MWAT evaluation guideline. For this listing cycle we are utilizing an MWMT evaluation guideline, instead of an MWAT, as it better captures temperature extremes. |

|
Evaluation Guideline: |
If the natural receiving water temperature has been altered, or if alternation is unknown, the evaluation guideline to determine adverse affect on the most sensitive beneficial use (in this case, salmonids) is as follows. Per "U.S. EPA Region 10 Guidance for Pacific Northwest State and Tribal Temperature Water Quality Standards" (USEPA 2003), the U.S. EPA recommends a criterion for the protection of moderate to high density summertime salmon and trout juvenile rearing (i.e., core juvenile rearing) of a maximum weekly maximum temperature (MWMT) of 16 degrees C. The MWMT is also known as the maximum 7-day average of daily maximums (7DADM). The 16 degrees C MWMT criterion is recommended to (1) safely protect juvenile salmon and trout from lethal temperatures; (2) provide upper optimal conditions for juvenile growth under limited food during the period of summer maximum temperatures and optimal temperatures for other times of the growth season; (3) avoid temperatures where juvenile salmon and trout are at a competitive disadvantage with other fish; (4) protect against temperature induced elevated disease rates; and (5) provide temperatures that studies show juvenile salmon and trout prefer and are found in high densities. |

|
Evaluation Guideline: |
Physical characteristics of a site vary due to both natural factors and human disturbance. Statistical models based on a large statewide reference data set can help distinguish natural variability from anthropogenic stress. These models work across the diverse stream types found in California. The Index of Physical Habitat Integrity (IPI) is a multimetric Index developed based on these models to characterize physical habitat condition for streams in California. Index scores near 1 indicate physical habitat conditions similar to reference, whereas lower scores indicate degradation. For the purposes of making statewide assessments, three thresholds (analogous to those used for the CSCI) were established based on the 30th; 10th; and 1st percentiles of IPI scores at reference sites. These three thresholds divide the IPI scoring range into 4 categories of physical condition as follows: greater than or equal to 0.94 = likely intact condition; 0.93 to 0.84 = possibly altered condition; 0.83 to 0.71 = likely altered condition; less than or equal to 0.70 = very likely altered condition. Scores of 0.83 or lower indicate that the physical habitat has been altered and low CSCI scores from this site may be due to impacts to the physical habitat. |

|
Evaluation Guideline: |
The California Stream Condition Index (CSCI) is a biological scoring tool that helps aquatic resource managers translate complex data about benthic macroinvertebrates found living in a stream into an overall measure of stream health. The CSCI score is calculated by comparing the expected condition with actual (observed) results (Rhen, A.C. et al., 2015). CSCI scores range from 0 (highly degraded) to greater than 1 (equivalent to reference). CSCI scoring of biological condition are as follows (per the scientific paper supporting the development of the CSCI scoring tool): greater than or equal to 0.92 = likely intact condition, 0.91 to 0.80 = possibly altered condition, 0.79 to 0.63 = likely altered condition, less than or equal to 0.62 = very likely altered condition. Sites with scores below 0.79 are considered to have exceeded the water quality objective for the aquatic life beneficial use. |

The 16 degrees C MWMT criterion is recommended to (1) safely protect juvenile salmon and trout from lethal temperatures; (2) provide upper optimal conditions for juvenile growth under limited food during the period of summer maximum temperatures and optimal temperatures for other times of the growth season; (3) avoid temperatures where juvenile salmon and trout are at a competitive disadvantage with other fish; (4) protect against temperature induced elevated disease rates; and (5) provide temperatures that studies show juvenile salmon and trout prefer and are found in high densities. |

Data Used to Assess Water Quality: |
Temperature data were evaluated against the temperature requirements of the beneficial use most sensitive to increases in temperature, salmonids. The most sensitive lifestage occurring during July, August, & September when the MWMTs occur is rearing. 0 of 7 MWMT values calculated from temperature samples collected in Redwood Creek exceed the evaluation guideline for the protection of core-rearing. MWMT values ranged from 13.2 to 15.7 degrees C. This LOE replaces the portion of LOE 1678 that contains data for Redwood Creek from the 2006 Listing Cycle. In LOE 1678 the raw temperature data was compared to the MWAT evaluation guideline, when in fact MWAT values should have been calculated from the raw data and compared to the MWAT evaluation guideline. For this listing cycle we are utilizing an MWMT evaluation guideline, instead of an MWAT, as it better captures temperature extremes. |

Data Used to Assess Water Quality: |
Temperature data were evaluated against the temperature requirements of the beneficial use most sensitive to increases in temperature, salmonids. The most sensitive lifestage occurring during July & August when the MWMTs occur is rearing. 7 of 7 MWMT values calculated from temperature samples collected in Wildcat Creek exceed the evaluation guideline for the protection of core-rearing. MWMT values ranged from 17.4 to 19.8 degrees C. This LOE replaces the portion of LOE 1678 that contains data for Wildcat Creek from the 2006 Listing Cycle. In LOE 1678 the raw temperature data was compared to the MWAT evaluation guideline, when in fact MWAT values should have been calculated from the raw data and compared to the MWAT evaluation guideline. For this listing cycle we are utilizing an MWMT evaluation guideline, instead of an MWAT, as it better captures temperature extremes. |

Water Quality Objective/Criterion: |
Water Quality Control Plan, North Coast Region (NCRWQCB 2011): Natural receiving water temperature of intrastate waters shall not be altered unless it can be demonstrated to the satisfaction of the Regional Water Board that such alteration in temperature does not adversely affect beneficial uses. At no time or place shall the temperature of any COLD water be increased more than 5 degrees Fahrenheit (F) above natural receiving water temperature. |
Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) for the North Coast Region |
|
Evaluation Guideline: |
If the natural receiving water temperature has been altered, or if alternation is unknown, the evaluation guideline to determine adverse affect on the most sensitive beneficial use (in this case, salmonids) is as follows. Per "U.S. EPA Region 10 Guidance for Pacific Northwest State and Tribal Temperature Water Quality Standards" (USEPA 2003), the U.S. EPA recommends a criterion for the protection of moderate to high density summertime salmon and trout juvenile rearing (i.e., core juvenile rearing) of a maximum weekly maximum temperature (MWMT) of 16 degrees C. The MWMT is also known as the maximum 7-day average of daily maximums (7DADM). The 16 degrees C MWMT criterion is recommended to (1) safely protect juvenile salmon and trout from lethal temperatures; (2) provide upper optimal conditions for juvenile growth under limited food during the period of summer maximum temperatures and optimal temperatures for other times of the growth season; (3) avoid temperatures where juvenile salmon and trout are at a competitive disadvantage with other fish; (4) protect against temperature induced elevated disease rates; and (5) provide temperatures that studies show juvenile salmon and trout prefer and are found in high densities. |

Evaluation Guideline: |
EVIDENCE OF ALTERATION OF NATURAL RECEIVING WATER TEMPERATURE: Water temperatures in the South Fork HA have been altered and do not reflect natural receiving water temperatures as environmental factors that influence water temperature have been altered by human activities. Anthropogenic factors resulting in altered stream temperatures include the clearing of ripairan canopy for roads and timber production (USEPA 1999). EVIDENCE OF SALMONID PRESENCE & LIFE CYCLE USE: Coho, steelhead and Chinook are present in the South Fork Eel HA (USEPA 1999; Yoshiyama and Moyle 2010). Rearing occurs year round and spawning/ incubation/ emergence occurs from November to April (Busby et al. 1996; CDFG 2004; Myers et al. 1998). Non-core rearing occurs in the mainstem Eel River, while core rearing occurs in tributaries. |
