Data Used to Assess Water Quality: |
The following process is utilized to interpret the narrative Temperature Objective in the Basin Plan for impairment assessments. Step 1: determine if temperatures reflect natural conditions. 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): The water temperatures of the Gualala River watershed do not reflect natural conditions as environmental factors that influence water temperature have been altered, such as flow alteration and riparian shade removal (NCWAP 2003). EVIDENCE OF SALMONID PRESENCE & LIFE CYCLE USE: Coho and steelhead are present in the watershed (NCWAP 2003). Steelhead rearing occurrs during all months of the year (Moyle et. al. 2008) and spawning occurrs January through March for steelhead (Busby et al. 1996) and November through May for coho (CDFG 2004). The Gualala River watershed supports core rearing. |

State Water Board staff re-assessed SWAMP data for Mendocino Coast HU, Gualala River HA, Gualala River to determine beneficial use support and results are as follows: 0 of 0 samples exceed the criterion for Atrazine, Total. Three 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 29875 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. |

The following process is utilized to interpret the narrative Temperature Objective in the Basin Plan for impairment assessments. Step 1: determine if temperatures reflect natural conditions. 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. |

Evaluation Guideline: |
EVIDENCE OF ALTERATION OF NATURAL RECEIVING WATER TEMPERATURES (NON-NATURAL TEMPS): The water temperatures of the Gualala River watershed do not reflect natural conditions as environmental factors that influence water temperature have been altered, such as flow alteration and riparian shade removal (NCWAP 2003). EVIDENCE OF SALMONID PRESENCE & LIFE CYCLE USE: Coho and steelhead are present in the watershed (NCWAP 2003). Steelhead rearing occurrs during all months of the year (Moyle et. al. 2008) and spawning occurrs January through March for steelhead (Busby et al. 1996) and November through May for coho (CDFG 2004). The Gualala River watershed supports core rearing. |

|
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. |
