Data Used to Assess Water Quality: |
In the Russian River at Forestville Access Beach, e.coli samples were collected while fecal coliform samples were not collected. Since e. coli is one of the group of bacteria that comprise the fecal coliform group, it is logical that if median e.coli concentrations for any 30-day period are greater than 50 MPN / 100 ml, then the median fecal coliform concentrations for any 30-day period will also be greater than 50 MPN / 100 ml. Of the 14 e. coli samples collected, 6 median e. coli concentration values were calculated based on a minimum of not less than 5 samples for any 30-day period. Of these 6 median values, none exceed the objective. E.coli median values range from 10 to 20 MPN / 100 ml.
The samples were collected by staff of the North Coast Regional Water Quality Control Board. The data for 2007 are presented in the Russian River Pathogen Data Report of the Russian River Pathogen Project Database (ICE 2008). The data for 2008 are presented by the Regional Water Board (NCRWQCB 2008). |

In total between 1992 and 2008, of the 104 median fecal coliform or median e. coli samples collected from the Russian River at Healdsburg Memorial Beach, 49 exceed the objective. Fecal coliform samples were collected from 1980 to 2001. Of the 117 fecal coliform samples collected, 57 median fecal coliform concentration values were calculated based on a minimum of not less than 5 samples for any 30-day period. Of these 57 median values, 44 exceed the objective. The median values ranged from 49 to 240 MPN / 100 ml. From 2002 to 2008, e.coli samples were collected while fecal coliform samples were not collected. Since e. coli is one of the group of bacteria that comprise the fecal coliform group, it is logical that if median e.coli concentrations for any 30-day period are greater than 50 MPN / 100 ml, then the median fecal coliform concentrations for any 30-day period will also be greater than 50 MPN / 100 ml. Of the 71 e. coli samples collected, 47 median e. coli concentration values were calculated based on a minimum of not less than 5 samples for any 30-day period. Of these 47 median values, 5 exceed the objective. E.coli median values range from 10 to 53 MPN / 100 ml. The samples were collected by staff of the North Coast Regional Water Quality Control Board.

Samples were collected from the mainstem Russian River at Healdsburg Memorial Beach near Healdsburg. Samples collected in 2001, from May to June 11, 2002, and from May to June 26, 2007, were collected from the west bank. All the rest of the samples were collected from the east bank in front of lifeguard stand 3 at the downstream end of the swim area. Samples were collected as far into the main river flow as possible while wading. |
Temporal Representation: |
The samples were collected once in June 1980, October 1986, June 1988, and once a month from June to August 1989. In 1987-1994, 1997-2003, and 2005-2006, samples were generally collected once a week during the summer months between Memorial Day and Labor Day. In 2007, samples were collected from July 3 to August 7. In 2008, samples were collected from Memorial Day to July 15. The samples were often collected on the same day of the week and at the same time of day. |

Data Used to Assess Water Quality: |
In total between 1997 and 2008, of the 103 median fecal coliform or median e. coli samples collected from the Russian River at Monte Rio Beach, 29 exceed the objective.
Fecal coliform samples were collected from 1997 to 2001. Of the 70 fecal coliform samples collected, 49 median fecal coliform concentration values were calculated based on a minimum of not less than 5 samples for any 30-day period. Of these 49 median values, 16 exceed the 50 MPN / 100 ml objective and 4 exceed the 400 MPN / 100 ml objective. Fecal coliform median values range from 2 to 9200 MPN / 100 ml.
From 2002 to 2008, e.coli samples were collected while fecal coliform samples were not collected. Since e. coli is one of the group of bacteria that comprise the fecal coliform group, it is logical that if median e.coli concentrations for any 30-day period are greater than 50 MPN / 100 ml, then the median fecal coliform concentrations for any 30-day period will also be greater than 50 MPN / 100 ml. Of the 78 e. coli samples collected,
54 median e. coli concentration values were calculated based on a minimum of not less than 5 samples for any 30-day period. Of these 54 median values, 9 exceed the objective. E.coli median values range from 10 to 178 MPN / 100 ml.
The samples were collected by staff of the North Coast Regional Water Quality Control Board. The data for 1997 to 2007 are presented in the Russian River Pathogen Data Report of the Russian River Pathogen Project Database (ICE 2008). The data for 2008 are presented by the Regional Water Board (NCRWQCB 2008). |

Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) for the North Coast Region |
|
Evaluation Guideline: |
HuBac (Bacteroides) are present in the human gut and do not survive long outside of the human gut. When present in the water column, measurable HuBac indicate the recent discharge of human fecal waste. There is no defined health-based threshold associated with HuBac results. The detection limit for HuBac is <60/100mL. HuBac concentrations >1000/100mL, which is two orders of magnitude greater than the detection limit, is reliable evidence of the presence of human fecal waste. |
Guideline Reference: |
Detection of the human specific Bacteroides genetic marker provides evidence of widespread sewage contamination of stormwater in the urban environment. |

Spatial Representation: |
The samples were collected from the mainstem Russian River at Steelhead Beach (near Forestville), Forestville Access Beach (near Hacienda), Odd Fellows Bridge (near Korbel), and Johnson's Beach (in Guerneville). The Odd Fellows Bridge sampling site is accessed via Odd Fellows Park Road and the samples are collected by wading from the small sandy beach upstream of the summer bridge. The Johnson's Beach sampling site is located downstream of the children's swim area and upstream of the bridge. Samples were collected as far into the main river flow as possible while wading. |
Temporal Representation: |
For all the samples collected between 2006 and 2007, samples were generally collected once a week during the summer months between Memorial Day and Labor Day. For all of the samples collected in 2008, samples were collected once a week from May 27 to July 15, 2008. The samples were often collected on the same day of the week and at the same time of day. For Steelhead Beach and Johnson¿s Beach, the samples were collected in 2006-2008. For Forestville Access Beach, the samples were collected in 2007-2008. For Odd Fellows Bridge, the samples were collected in 2006. |
Environmental Conditions: |
There are no known environmental conditions (e.g., seasonality, land use practices, fire events, storms, etc.) that are related to these data. |

Data Used to Assess Water Quality: |
One of the 38 Enterococcus samples from the Russian River at Healdsburg Memorial Beach exceeds the evaluation guideline. Sample concentrations ranged from less than 10 to 109 MPN / 100 ml. The samples were collected by staff of the North Coast Regional Water Quality Control Board. The data for 2006-2007 are presented in the Russian River Pathogen Data Report of the Russian River Pathogen Project Database (ICE 2008). The data for 2008 are presented by the Regional Water Board (NCRWQCB 2008). This LOE is an exact duplicate of LOE 5943 from the Russian River HU, Middle Russian River HA, Geyserville HSA water body. The data from the Russian River at Healdsburg Memorial Beach was incorrectly assessed in the Geyserville HSA water body, and this LOE represents the transfer of that data to the correct water body. No changes were made to the original LOE aside from placing it in the correct water body. LOE 5943 will not be used in the Indicator Bacteria Decision in the Geyserville HSA, and will be retired after the change has been reflected and this listing cycle has been completed. |

Fourteen sample results were not used in the assessment because the laboratory data reporting limit(s) was above the objective and therefore the results could not be quantified with the level of certainty required by the Listing Policy. This LOE re-assesses data from LOE 29886 from the 2010 Integrated Report. Data were re-assessed in order to (1) update the numeric objective, and (2) evaluate these data in their own LOE, instead of being evaluated in the same LOE as other pesticide data. |

If Yes, then the water body is not considered impaired, if No, Then go to Step 2. Step 2: Determine if temperatures adversely affect beneficial uses. If Yes, then the water body is considered impaired, if No, then go to Step 3. Step 3: Determine if temperatures are increased by 5 degrees F. If Yes, then water body is impaired, if No, then water body is not impaired. |

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: |
EVIDENCE OF ALTERATION OF NATURAL RECEIVING WATER TEMPERATURES (NON-NATURAL TEMPS): Water temperatures of the Russian River HA, including the Guerneville HSA, do not reflect natural conditions as environmental factors that influence water temperature have been altered by human activities. Examples of human alteration to the Russian River include flow changes resulting from the Potter Valley Project and dam construction, as well as landuse practices, such as logging and agriculture, which have resulted in alterations to streambanks, channel morphology, and stream temperatures (FERC 2002). EVIDENCE OF SALMONID PRESENCE & LIFE CYCLE USE: Coho, steelhead, and Chinook are all present in the Russian River watershed (CDFG 2002). Spawning, incubation, and emergence for these three salmonid species cumulatively occurs November through the end of May. Steelhead juveniles rear year-round in the Russian River (Steiner Environmental Consulting 1996). |

|
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. |

|
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. |

This LOE re-assesses data from LOE 6085 from the 2010 Integrated Report cycle, which incorrectly compared the data against the site-specific specific conductivity objective for the mainstem Russian River. The data are now compared to the secondary MCL as is appropriate. |

Water Quality Objective/Criterion: |
Per the Basin Plan (NCRWQCB 2011): 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. At no time or place shall the temperature of WARM intrastate waters be increased more than 5°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 not been altered, or if alternation is unknown, the evaluation guideline to determine adverse affect on the mostsensitive beneficial use (in this case, salmonids) is as follows. Per the "Effects of Temperature, Dissolved Oxygen/Total Dissolved Gas, Ammonia, and pH on Salmonids" (Carter 2008), the lethal temperature evaluation guidelines for the most sensitive salmonid species (in this case, steelhead trout) are 20°C during spawning, egg incubation, and fry emergence and 24°C during adult migration, adult holding, and juvenile growth and rearing. These guidelines are for chronic exposure and require data that is collected for at least 7 consecutive days as salmonids may survive brief periods at these temperatures.

Data Used to Assess Water Quality: |
The natural receiving water temperature of Fife Creek has been altered due to the removal of riparian vegetation and the subsequent loss of shade, human landscaping along channel banks downstream of Armstrong Woods, changes in the channel substrate and geometry from excess sediment loads, and other human activities. In order to determine if temperature adversely affects beneficial uses, Regional Water Board staff attempted to compare the samples to the 20°C and 24°C lethal temperature evaluation guidelines. It is unknown if any of the 3 samples exceed the evaluation guideline as the samples were not collected over 7 consecutive days and were therefore incomparable. The samples were collected as part of a targeted sampling event on Fife Creek. Data are summarized in Goodwin (1999). |

Water Quality Objective/Criterion: |
Per the Basin Plan (NCRWQCB 2007, p. 3-4.00): 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. At no time or place shall the temperature of WARM intrastate waters be increased more than 5°F above natural receiving water temperature. |
Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) - North Coast Region (Region 1) |
|
Evaluation Guideline: |
If the natural receiving water temperature has not 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 the "Effects of Temperature, Dissolved Oxygen/Total Dissolved Gas, Ammonia, and pH on Salmonids" (Carter 2008), the lethal temperature evaluation guidelines for the most sensitive salmonid species (in this case, steelhead trout) are 20°C during spawning, egg incubation, and fry emergence and 24°C during adult migration, adult holding, and juvenile growth and rearing. These guidelines are for chronic exposure and require data that is collected for at least 7 consecutive days as salmonids may survive brief periods at these temperatures. Acute lethal temperature thresholds were selected by Carter (2008) based upon best professional judgment of the literature. |

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: |
One DDT sample collected in the Guerneville HSA had a detectable level of DDT and the sample exceeds the evaluation guideline. The sample concentration was reported as detected not quantifiable (DNQ), with estimated value of .003 ug/l (method detection limit of 0.002 ug/l, reporting limit of .005 ug/l). There were also an additional 18 samples from the Guerneville HSA, which were non-detect. However, these non-detect data could not be utilized in this assessment because the detection limit for DDT is above the evaluation guideline. Per the listing policy, when a sample value is less than the quantitation limit, and the quantitation limit is greater than the evaluation guideline, the result shall not be used in the analysis. The samples were collected as part of the Surface Water Ambient Water Monitoring Program (SWAMP) (NCRWQCB 2008). |

Data Used to Assess Water Quality: |
None of the DDT samples collected in the Russian River at Healdsburg Memorial Beach had a detectable level of DDT. Non-detect data could not be utilized in this assessment because the detection limit for DDT is above the evaluation guideline. Per the listing policy, when a sample value is less than the quantitation limit, and the quantitation limit is greater than the evaluation guideline, the result shall not be used in the analysis. The samples were collected as part of the Surface Water Ambient Water Monitoring Program (SWAMP) (NCRWQCB 2008). This LOE and LOE 46527 contain data originally evaluated in LOE 25639, which included data from a site that is not in this water body. The data from LOE 25639 have been split into two LOEs, with data now evaluated under the correct water body. |

Data Used to Assess Water Quality: |
State Water Board staff re-assessed SWAMP data for Russian River HU, Lower Russian River HA, Guerneville HSA to determine beneficial use support and results are as follows: 0 of 0 samples exceed the criterion for Dacthal, Total. Twenty sample results were not used in the assessment because the laboratory data reporting limit(s) was above the objective and therefore the results could not be quantified with the level of certainty required by the Listing Policy. This LOE re-assesses data from LOE 29886 from the 2010 Integrated Report. Data were re-assessed in order to evaluate these data in their own LOE, instead of being evaluated in the same LOE as other pesticide data. |
