|
Weight of Evidence: |
This pollutant is being considered for placement on the section 303(d) list under section 3.2 of the Listing Policy (Policy).
Six lines of evidence are available in the administrative record to assess this pollutant. These are temperature data on five life stages for anadromous fish and information on the historical and current state of the fishery. A large number of seven-day averages of maximum (7DADM) daily temperatures exceeded the anadromous fish life stage temperature criteria.
Based on readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of placing this water segment-pollutant combination on the section 303(d) list in the Water Quality Limited Segments category.
This conclusion is based on the staff findings that:
1. The data used satisfies the data quality requirements of section 6.1.4 of the Policy.
2. The data used satisfies the data quantity requirements of section 6.1.5 f the Policy.
3. Thirty-eight of 76 yearly maximum 7DADM values calculated from temperature data collected during the adult migration life stage (Julian weeks 36 through 43) from 1991 to 2007 exceeded the narrative temperature objective, and this exceeds the minimum criteria for listing from Table 3.2 of the Policy.
4. Thirty-eight of 49 yearly maximum 7DADM values calculated from temperature data collected during the spawning life stage (Julian weeks 40 through 50) from 1999 to 2007 exceeded the narrative temperature objective, and this exceeds the minimum criteria for listing from Table 3.2 of the Policy.
5. Thirty-six of 73 yearly maximum 7DADM values calculated from temperature data collected during the smoltification life stage (Julian weeks 11 through 24) from 1999 to 2007 exceeded the narrative temperature objective, and this exceeds the minimum criteria for listing from Table 3.2 of the Policy.
6. Thirty-six of 73 yearly maximum 7DADM values calculated from temperature data collected during the juvenile rearing life stage (Julian weeks 11 through 24) from 1999 to 2007 exceeded the narrative temperature objective, and this exceeds the minimum criteria for listing from Table 3.2 of the Policy.
7. Seven of 27 yearly maximum 7DADM values calculated from temperature data collected during the steelhead summer rearing life stage (Julian weeks 24 through 37) from 1999 to 2007 exceeded the narrative temperature objective, and this exceeds the minimum criteria for listing from Table 3.2 of the Policy.
8. Pursuant to section 3.11 of the Policy, no additional data and information are available indicating that standards are not met.
9. The data used satisfies the data quality requirements of section 6.1.4.5.7 of the Policy. |
|
RWQCB Board Decision / Staff Recommendation: |
After review of the available data and information, RWQCB-CVR staff concludes that the water body pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem. |

Stream temperatures were measured by California Department of Fish and Game (CDFG) using data loggers (Stowaway, Tidbits and Hobo Temp Pros). Monitoring occurred from 1999 to 2007 depending on the monitoring station, identified by a river mile. The 7DADM was recorded weekly for each river mile. The maximum 7DADM value was calculated for each year. Based on the data provided, 38 out of 76 maximum 7DADM values exceeded the <18oC criteria from 1999 to 2007. |

Evaluation Guideline: |
The guideline used was the 2003 US EPA Region 10 Guidance for Pacific Northwest State and Tribal Temperature Water Quality Standards (USEPA, 2003). The document includes recommended temperature criteria for salmon and trout based on different life stages. The recommended temperature for salmon and trout adult migration is <18oC for a 7DADM. The adult migration life stage occurs from river mile 0 (confluence with the San Joaquin River) to river mile 58 (Goodwin Dam). This life stage occurs during Julian weeks 36 through 43, which is approximately September 1st through October 31st. |

QUALITATIVE (EVALUATED) ASSESSMENT - UNSPECIFIED |
Data Used to Asses Water Quality: |
The Stanislaus has a good spring and fall-run of salmon (G.H. Clark, 1929). Prior to Tulloch Dam (1958) the average annual fall-run escapement averaged 10,300 spawners (Yoshiyama, Ronald M., Eric R. Gerstun, Frank W. Fisher, and Peter. B. Moyle, 2001). Post Tulloch, escapement declined to an average of 4,300 spawners.
After New Melones Reservoir was operating in the 1970s, annual escapement dropped to an average of 3,600 spawners. Since 2000, the escapement population has steadily declined and by 2006 had dropped to about 65% below the year 2000 peak population. Also, populations have declined when Delta exports and ocean harvesting was reduced at the same time (CDFG July 2007 Letter to the Federal Energy Regulatory Commission). Between 1952 and 2006 the fall-run escapement population has oscillated over time and has dropped to levels less than 1,000 on several occasions.
The Department of Fish and Game has submitted data to the Regional Water Quality Control Board regarding warm water temperatures present in the lower Stanislaus River during the fall adult upstream migration seasons for the years 1999 thru 2006 (Tables 7 and 10 in CDFGs Letter to the RWQCB, 2007). Also, the Department of Fish and Game has submitted data to the Regional Water Quality Control Board regarding warm water temperatures present in the lower Stanislaus River spawning habitat reaches during the first half of the spawning season for years 1999 thru 2005 (Table 11 in CDFGs Letter to the RWQCB, 2007). Data collected in 2002 at Orange Blossom Bridge shows as water temperature decreased below 13°C, spawning activity, measured by weekly spawning redd counts, rises (Jason Guignard, 2002).
Steelhead in the Stanislaus are considered winter run. Adult steelhead have been recently captured while migrating upstream at the fish counting weir located near Riverbank (Cramer Fish Sciences) Juvenile rainbow trout have been caught in rotary screw traps out-migrating the Stanislaus River. Anecdotal reports by anglers suggest that steelhead populations are good following years where summer rearing conditions are good (e.g. presence of cold water temperatures).
State and Federal agencies believe their abundance trends mirrors those of salmon causing them to be listed as threatened in the Central Valley. The Department of Fish and Game submitted data to the Regional Water Quality Control Board regarding warm water temperatures present in the lower Stanislaus River juvenile steelhead rearing reaches during the summer for years 1999 thru 2006 (Table 11 in CDFGs Letter to the RWQCB, 2007). |

Water Quality Objective/Criterion: |
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.
In determining compliance with the water quality objectives for temperature, appropriate averaging periods may be applied provided that beneficial uses will be fully protected. (Central Valley Regional Board Basin Plan, Pg. III-8.00, Water Quality Objectives) |

|
Evaluation Guideline: |
In the absence of necessary data to interpret numeric water quality objectives, recent temperature monitoring data shall be compared to the temperature requirements of aquatic life in the water segment. In many cases, fisheries, particularly salmonids, represent the beneficial uses most sensitive to temperature. Information on current and historic conditions and distribution of sensitive beneficial uses (e.g., fishery resources) in the water segment is necessary, as well as recent temperature data reflective of conditions experienced by the most sensitive life stage of the aquatic life species. If temperature data from past (historic) periods corresponding to times when the beneficial use was fully supported are not available, information about presence/absence or abundance of sensitive aquatic life species shall be used to infer past (historic) temperature conditions if loss of habitat, diversions, toxic spills, and other factors are also listed.
